Ingredients
Cookie Base
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1 tablespoon lemon zest (about 1 large lemon)
- 1 tablespoon fresh lemon juice
- 2 cups all-purpose flour
- ½ teaspoon baking powder
- ¼ teaspoon baking soda
- ¼ teaspoon salt
Lemon Curd Filling
- 3 large egg yolks
- ½ cup granulated sugar
- 2 tablespoons cornstarch
- ½ cup water
- ¼ cup fresh lemon juice
- 1 tablespoon unsalted butter
- ½ teaspoon lemon zest
Meringue Topping
- ½ cup granulated sugar

- 3 tablespoons water

Tips for the Best Results
Follow these simple tips to ensure your cookies turn out perfectly:
- Create the well while warm: Right after baking, press the back of a teaspoon into each cookie to form a small well while the cookie is still warm and pliable.
- Cool completely before filling: Fill cooled cookies so the curd stays in place instead of melting into the cookie.
- Stiffen the whites fully: Whip egg whites to full stiff peaks before adding the hot sugar syrup for the most stable meringue.
- Pour syrup slowly: Add the hot sugar syrup in a thin, steady stream while mixing on high to prevent deflating the whites.
- Check meringue temperature: Continue beating until the meringue is glossy and the mixing bowl feels close to room temperature—this indicates it’s done.
- Brown carefully: Use a kitchen torch for delicate browning; if you don’t have one, a very brief 2–3 minute bake at 400°F will toast the tips.
Storage
Store the assembled cookies covered in the refrigerator for up to three days for best texture and flavor. After three days the meringue can begin to weep and lose its structure, although the cookies remain safe to eat. The lemon curd can be made up to three days ahead and kept refrigerated until assembly.

Instructions
Cookies
- Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Cream the softened butter and sugar until light and fluffy, about 2–3 minutes. Beat in the egg, vanilla, lemon zest, and lemon juice until smooth.
- Whisk together the flour, baking powder, baking soda, and salt. Add to the wet ingredients and mix until just combined.
- Scoop about 1½ tablespoons of dough per cookie and roll into balls. Place on the prepared sheet and bake 10–12 minutes, until edges are lightly golden and centers are set.
- Immediately press the back of a teaspoon into the center of each warm cookie to form a shallow well. Cool completely before filling.
Lemon Curd Filling
- In a saucepan, whisk egg yolks, sugar, cornstarch, water, and lemon juice until smooth.
- Cook over medium heat, whisking constantly, until the mixture thickens and becomes glossy, about 5–7 minutes.
- Remove from heat and stir in butter and lemon zest. Let cool until slightly warm, then spoon about 1 teaspoon into each cookie well. Chill while preparing the meringue.
Meringue Topping (Italian Meringue)
- Whip egg whites (with cream of tartar if using) to stiff peaks.
- Combine sugar and water in a saucepan and cook to 244°F (soft-ball stage) or test by dropping a bit of syrup into cold water to form a soft ball.
- With the mixer running on high, pour the hot syrup in a thin, steady stream into the whipped whites. Continue beating until the meringue is glossy and the bowl feels close to room temperature.
Assembly
- Spoon or pipe meringue over each lemon-filled cookie.
- Optionally torch the tops lightly with a kitchen torch for an even, toasted finish. Alternatively, place cookies briefly under a hot oven (about 400°F) for 2–3 minutes to brown the tips—watch carefully.
- Allow to cool completely before serving.
Frequently Asked Questions
Is Italian meringue safe to eat without baking? Yes. The hot sugar syrup cooks the egg whites as it is incorporated, making Italian meringue safe to eat immediately.
Can I make the lemon curd ahead? Yes. Lemon curd can be made up to three days in advance and kept refrigerated until ready to use.
Why might my meringue weep or deflate? If the syrup wasn’t hot enough or the egg whites weren’t whipped to full stiff peaks before adding syrup, the meringue may lose stability. Follow temperature and whipping guidelines for best results.
Can I skip the candy thermometer? Yes. Use the cold water test: drop a bit of syrup into cold water and if it forms a soft ball between your fingers, it’s ready.
How long do the cookies keep? For best texture, enjoy within three days when stored covered in the refrigerator. After three days the meringue may begin to weep, though they remain safe to eat.
