Why You’ll Love These Copycat Crumbl Buckeye Brownie Cookies
These homemade Crumbl-inspired cookies aren’t just a dessert; they’re an experience designed to delight your senses. Here’s why they’ll quickly become a favorite:
- Three Layers of Unforgettable Indulgence: Imagine biting into a cookie where every layer contributes to an extraordinary taste and texture. First, a thick, fudgy brownie cookie provides a dense, chewy chocolate foundation. Next, a light and creamy whipped peanut butter filling offers a melt-in-your-mouth counterpoint. Finally, a silky smooth chocolate ganache seals the deal with a rich, glossy finish. Each distinct layer brings its own rich flavor and unique texture, ensuring that every single bite is a mini dessert adventure, perfectly balanced and utterly satisfying.
- The Ultimate Crumbl Dupe Experience: Say goodbye to long lines and premium prices. These cookies capture the essence of Crumbl’s bakery-sized, thick, and incredibly rich offerings, but with the added satisfaction of making them yourself. The flavor profile is uncannily spot-on, allowing you to enjoy that signature Crumbl taste while having complete control over the quality of your ingredients and, more importantly, saving a significant amount of money compared to the $5-per-cookie price tag. It’s an economical way to enjoy gourmet treats.
- A Fantastic Make-Ahead Dessert: Planning ahead has never been easier or more rewarding. The components of these cookies can be prepared in stages, allowing you to bake the fudgy brownie bases one day and assemble them with the creamy peanut butter filling and ganache the next. For ultimate convenience, you can even freeze the cookie bases and fillings separately, making it incredibly simple to whip up a batch of these delectable treats for a last-minute dessert craving or unexpected guests. This flexibility makes them perfect for busy schedules.
- Chocolate and Peanut Butter Lover’s Dream: If the iconic combination of chocolate and peanut butter, famously celebrated by Reese’s, makes your heart sing, then these cookies are your personal slice of heaven. They perfectly blend the deep, bittersweet notes of chocolate with the salty, nutty richness of peanut butter. The interplay of sweet and salty, combined with melty chocolate pockets and a chewy cookie texture, creates a truly harmonious flavor explosion that hits all the right notes for an unparalleled dessert experience.
- Remarkably Freezer-Friendly: Don’t worry about having too many cookies. These Buckeye Brownie Cookies freeze beautifully, even when fully assembled. This means you can bake a large batch and store them away for those moments when a sweet fix is absolutely necessary. Simply pull one out at a time, let it thaw, and enjoy a gourmet cookie whenever the craving strikes, maintaining its delightful texture and flavor.

Ingredients for Crumbl Copycat Buckeye Brownie Cookies
Crafting these bakery-worthy treats involves three distinct yet simple components, each contributing to the cookie’s overall richness and complexity. Here’s a detailed look at the ingredients you’ll need for each layer, along with their crucial roles:
Brownie Cookie Base
This is the fudgy, chocolatey foundation that gives these cookies their incredible depth and chewy texture.
- Unsalted Butter: When melted, butter provides a rich, moist, and wonderfully chewy texture, essential for mimicking a true brownie. It also adds a deep, buttery flavor that complements the chocolate beautifully.
- Brown Sugar: This adds significant moisture to the cookie dough, contributing to its soft and chewy interior. The molasses content in brown sugar also imparts a subtle caramel-like flavor, enhancing the overall sweetness.
- Granulated Sugar: Balances the sweetness from the brown sugar and aids in the cookie’s structure. It helps create those slightly crisp edges while keeping the center tender.
- Large Eggs: Eggs are vital for binding the ingredients together, providing structure and richness. They also contribute to the tender crumb and moisture content, ensuring the cookies aren’t dry.
- Vanilla Extract: A cornerstone in almost any baked good, vanilla extract deepens and enhances all the other flavors, adding a warm, sweet aroma and taste that is irreplaceable.
- All-Purpose Flour: The primary structural component of the dough, all-purpose flour gives the cookies their shape and body. Proper measurement is key to avoiding dry or overly dense cookies.
- Unsweetened Cocoa Powder: Essential for that intense, deep chocolate flavor. Using unsweetened cocoa powder allows you to control the sugar content and achieve a more pronounced chocolate taste, rather than an overly sweet one.
- Salt: A small but mighty ingredient, salt is crucial for balancing the sweetness and truly bringing out the robust flavors of both chocolate and peanut butter, preventing the cookies from tasting flat.
- Baking Soda: This leavening agent helps the cookies rise slightly and contributes to a soft, tender, and slightly chewy texture, preventing them from becoming too dense.
- Semi-Sweet Chocolate Chips: Folded into the dough, these chips melt into delightful pockets of extra chocolatey goodness, adding another layer of indulgence and texture to the brownie base.
Peanut Butter Filling
This creamy, dreamy layer is the heart of the “buckeye” experience, offering a smooth and irresistible peanut butter punch.
- Unsalted Butter (softened): Softened butter is key to achieving a smooth, creamy, and rich filling. It provides a luxurious mouthfeel and helps the frosting spread effortlessly.
- Creamy Peanut Butter: The star of this layer, creamy peanut butter delivers that bold, nutty, and slightly salty flavor that defines a buckeye. For the best, most consistent texture that holds its shape, it’s highly recommended to use a “no-stir” brand like Jif or Skippy, as natural peanut butter can be too oily.
- Powdered Sugar: Also known as confectioners’ sugar, this finely milled sugar sweetens the filling and is essential for creating that thick, smooth, and spreadable frosting-like consistency that sets beautifully.
- Vanilla Extract: Just like in the cookie base, vanilla extract enhances the overall flavor profile, adding a warm undertone that complements the peanut butter.
Chocolate Ganache
The final, glossy touch that elevates these cookies to a professional bakery standard, adding rich chocolate and a beautiful sheen.
- Semi-Sweet Chocolate Chips: These melt down to form the rich, shiny, and decadent topping. Semi-sweet chocolate provides the perfect balance, ensuring the ganache isn’t overly sweet and pairs well with the already sweet filling and cookie.
- Heavy Cream: The secret to a perfectly smooth and glossy ganache. Heavy cream, when heated and combined with chocolate, creates an emulsion that is both pourable when warm and sets with a soft, luxurious bite when cool.

Expert Tips for Baking Perfect Crumbl Copycat Buckeye Brownie Cookies
Achieving bakery-quality results at home is easier than you think with these helpful tips. While full detailed instructions are available in the recipe card below, these insights will ensure your Copycat Crumbl Buckeye Brownie Cookies turn out absolutely perfect every time.
- Embrace Room Temperature Ingredients: This tip is fundamental for both the cookie dough and the peanut butter filling. Allowing ingredients like eggs and the butter for your filling to come to room temperature before you start mixing ensures they incorporate smoothly and uniformly into your batters and frostings. This seamless integration results in a more consistent and superior texture across all three layers, guaranteeing a soft, tender cookie and a perfectly creamy filling.
- Scoop Your Dough Tall, Not Wide: When portioning out your cookie dough, resist the urge to flatten the mounds. Instead, use a large cookie scoop or two spoons to create tall, substantial mounds of dough on your baking sheet. This technique is crucial for encouraging the cookies to bake up thick and chewy, rather than spreading out into thin, flat discs. Aiming for height helps achieve that coveted bakery-style thickness and a wonderfully dense, fudgy center.
- Master the Art of Not Overbaking: This is perhaps the most critical tip for achieving that signature fudgy brownie base. These cookies should be removed from the oven when their edges are just set but their centers still appear slightly soft and perhaps a little underdone. Don’t worry, they will continue to firm up and set beautifully as they cool on the hot baking sheet and then on a wire rack. Overbaking is the quickest way to dry out your brownie base, sacrificing that rich, moist, and fudgy texture you’re striving for.
- Cool Completely Before Assembling: Patience is a virtue, especially when layering these cookies. It’s incredibly tempting to rush the assembly process, but if the cookies are even slightly warm, the delicate peanut butter filling and the glossy chocolate ganache will melt, slide, and create a messy situation. For clean, distinct, and stackable layers, ensure your cookie bases are completely cool to the touch before you begin spreading any toppings.
- Chill After Assembly for the Best Set: Once you’ve lovingly spread the peanut butter filling and drizzled the chocolate ganache over your cooled cookie bases, a brief chill in the refrigerator works wonders. Placing the assembled cookies in the fridge for about 15-20 minutes allows the layers to set properly. This firming-up process not only enhances the cookie’s structural integrity but also makes them significantly easier to store, stack, and transport without any smudging or smearing of the beautiful toppings. This step guarantees a pristine finish and a delightful eating experience.

Effective Storage Solutions for Your Buckeye Brownie Cookies
These magnificent cookies are so delicious, you’ll want to savor them for as long as possible. Proper storage is key to maintaining their fresh taste and perfect texture. Here’s how to store your Crumbl Copycat Buckeye Brownie Cookies:
- Room Temperature: For immediate enjoyment, store your cookies in an airtight container at cool room temperature for up to 3 days. To prevent the delicate ganache from sticking or smudging, it’s a good practice to place a piece of parchment paper between layers of cookies. This keeps each cookie looking as pristine as when it was first made.
- Refrigerator: If you want to extend their freshness, these cookies can be stored in an airtight container in the refrigerator for up to 1 week. Be aware that the chocolate ganache will firm up considerably when chilled. For the best eating experience, allow the cookies to sit out at room temperature for 10-15 minutes before serving. This brief warm-up will soften the ganache and bring out the full depth of flavors.
- Freezer: For long-term storage, these cookies are excellent candidates for freezing. You can freeze fully assembled cookies in an airtight container for up to 2 months. Again, layering with parchment paper is advisable to protect the toppings. Alternatively, if you prefer the freshest possible toppings, you can freeze just the baked brownie cookie bases. When ready to serve, thaw the bases and then apply the freshly made peanut butter filling and chocolate ganache for optimal texture and flavor.
- Thawing Tip: When retrieving cookies from the freezer, the simplest method is to let them sit at room temperature for approximately 30 minutes. If you’re in a hurry and want to gently soften the ganache, a quick 10-second blast in the microwave can do the trick, but be careful not to overheat and melt the layers entirely.

Ingredients
Brownie Cookie Base
- 1 cup unsalted butter, melted
- 1 cup brown sugar
- ½ cup granulated sugar
- 2 large eggs
- 1 tsp vanilla extract
- 1 ¾ cups all-purpose flour
- 1 cup unsweetened cocoa powder
- 1 tsp salt
- 1 tsp baking soda
- 2 cups semi-sweet chocolate chips
Peanut Butter Filling
- ½ cup unsalted butter, softened
- 1 cup creamy peanut butter
- 2 cups powdered sugar
- 1 tsp vanilla extract
Chocolate Ganache
- 2 cups semi-sweet chocolate chips
- ¾ cup heavy cream
Instructions
- Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.
Make the cookie dough:
- Melt the butter and let it cool slightly to prevent cooking the eggs.
- In a stand mixer or with a hand mixer, cream the slightly cooled melted butter with both brown sugar and granulated sugar until the mixture is smooth and well combined.
- Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract until fully incorporated.
- In a separate bowl, whisk together the flour, cocoa powder, salt, and baking soda. Gradually add the dry ingredients to the wet ingredients, mixing on low speed just until combined and no streaks of flour remain. Be careful not to overmix.
- Gently fold in the semi-sweet chocolate chips by hand.
Scoop and bake:
- Use an ice cream scoop (about 3 tablespoons) or a large spoon to shape tall, generous mounds of cookie dough.
- Place the dough balls 2–3 inches apart on the prepared baking sheets to allow for spreading, and bake for 11–12 minutes. The edges should be set, but the centers will still look soft.
- Allow the cookies to cool completely on the baking sheets before attempting to assemble them with the toppings. This is crucial for clean layering.
Make the peanut butter filling:
- In a clean mixing bowl, cream together the softened unsalted butter and creamy peanut butter until the mixture is smooth and light.
- Add the vanilla extract and gradually incorporate the powdered sugar, whipping until the filling is thick, fluffy, and spreadable.
Make the ganache:
- In a microwave-safe bowl, combine the semi-sweet chocolate chips and heavy cream. Microwave on high for 1 minute, then remove and stir until smooth.
- If the chocolate is not fully melted and smooth, continue to heat in 15–30 second intervals, stirring well after each, until completely incorporated. Let the ganache cool slightly before using, as hot ganache will melt the peanut butter layer.
Assemble the cookies:
- Once the brownie cookies are completely cool, spread an even layer of the creamy peanut butter filling over the top of each cookie.
- Spoon a generous amount of the slightly cooled chocolate ganache over the peanut butter layer and gently spread it evenly with a small spatula or the back of a knife, ensuring full coverage.
- Allow the assembled cookies to sit at room temperature for 1-2 hours, or refrigerate for 15-20 minutes, until the ganache is fully set and firm to the touch.

Frequently Asked Questions About Buckeye Brownie Cookies
Here are answers to some common questions you might have while baking these delicious Copycat Crumbl Buckeye Brownie Cookies:
Can I use natural peanut butter in the filling?
It is generally not recommended to use natural peanut butter for the filling in this recipe. Natural peanut butter, especially the kind that separates, tends to be much oilier and runnier than conventional no-stir brands. This excess oil can make your peanut butter filling too loose to spread effectively and can cause it to slide right off the cookie base, making assembly a challenge. For the best consistency, a creamy, no-stir peanut butter (such as Jif or Skippy) is ideal, as it provides the perfect thick texture that sets nicely and holds its shape on the cookie.
Why are my cookies spreading too much in the oven?
If your cookies are spreading more than desired and turning out too thin, there are a few common culprits. One possibility is that your melted butter for the brownie base was too hot when you mixed it with the sugars, which can lead to a thinner dough. Always allow melted butter to cool slightly before incorporating it. Another reason could be that your cookie dough itself was too soft or warm. If you find your dough difficult to handle, a quick chill in the refrigerator for 20-30 minutes before scooping and baking can significantly help prevent excessive spreading, encouraging thicker cookies.
My cookies turned out dry — what might have happened?
The most frequent reason for dry cookies is overbaking. For these fudgy brownie cookies, you want them to be just set around the edges and still appear slightly soft, almost underbaked, in the very center when you pull them from the oven. They will continue to cook and firm up as they cool on the baking sheet. Additionally, inaccuracies in flour measurement can lead to dryness. Spooning flour directly from the bag can compact it, resulting in too much flour. For precise measurement, always spoon flour into your measuring cup and level it off with a straight edge, or, even better, weigh your flour using a kitchen scale for consistent results.
Can I use Dutch-process cocoa instead of regular unsweetened cocoa powder?
Yes, you can certainly try using Dutch-process cocoa powder, but be aware that it might subtly alter both the flavor and texture of your cookies. Dutch-process cocoa is treated to be less acidic and has a darker color and milder, smoother chocolate flavor compared to natural unsweetened cocoa. Because Dutch-process cocoa is alkaline, it reacts differently with leavening agents. Ensure your baking soda is fresh and active, as the chemical reaction needed for rise might be slightly different than with acidic natural cocoa powder. The result will still be delicious, but expect a potentially deeper, less bitter chocolate note.
How long does the ganache typically take to set?
At average room temperature (around 70-72°F or 21-22°C), the chocolate ganache will typically take about 1 to 2 hours to fully set and become firm to the touch. The actual time can vary depending on the ambient temperature and humidity of your kitchen. If you need to speed up the setting process, placing the assembled cookies in the refrigerator for about 15-20 minutes after applying the ganache will significantly firm it up. However, avoid storing them uncovered in the fridge for too long, as the ganache can become too hard and might lose some of its attractive glossy sheen.
Can I make these cookies gluten-free?
Yes, it is possible to adapt this recipe to be gluten-free. You can try substituting the all-purpose flour with a high-quality 1:1 gluten-free baking flour blend. When selecting a blend, ensure it already contains xanthan gum or another binder, as this is crucial for providing structure and preventing your cookies from being too crumbly. While the texture might vary slightly from the original, many bakers have successfully made this swap with excellent results. Start with a good blend, and you’ll likely achieve delicious gluten-free Buckeye Brownie Cookies.
