Perfect for gifting, these easy lemon thumbprint cookiesare madewith a lemon curd thumbprint and a buttery shortbread base. Use homemade microwave lemon curd or store-bought for these cute cookies!
Preheat the oven to 350ºF (180ºC) and line two baking sheets with parchment paper. Set aside.
In a medium mixing bowl, stir the flour, powdered sugar, and cornstarch until well combined. Set aside.
1 ¾ cups all-purpose flour, ¾ cup powdered sugar, ¼ cup cornstarch
Place the butter and vanilla in a large mixing bowl. Cream together on high speed until pale and light, about 1 to 2 minutes.
1 cup butter, 1 teaspoon vanilla extract
Add the flour mixture to the butter and mix on low speed until a dough forms that clears the sides of the bowl.
Divide the cookie dough into approximately sixty 15-gram portions. Roll each portion of dough between your hands to form a smooth ball.
Place the granulated sugar in a small bowl and roll each dough ball in it to coat. Arrange 30 dough balls on each baking sheet, leaving a little space between them. The cookies won't spread much as they bake.
3 tablespoons granulated sugar
Use the back of a ½ teaspoon measuring spoon to press a round indentation into each dough ball, stopping just short of the baking sheet. The indentation should form a neat, rounded well for the lemon curd.
Divide the lemon curd evenly among the cookies. Bake for 18 to 20 minutes, or until the curd is set and the bottoms are lightly golden. Transfer to a wire rack to cool completely before storing in an airtight container.
½ cup lemon curd
Notes
You can make the cookies any size; however, the baking time will change.
The dough for these cookies doesn't spread very much, although it does spread slightly around the 10-minute baking mark. I bake all 60 lemon curd cookies on one sheet, and sometimes a couple will stick together, but not too badly. If you're worried about them sticking together, bake 30 cookies per baking sheet.
Rolling the cookie dough balls in sanding sugar is optional, but I recommend it as it prevents the ½ teaspoon from sticking when making the indents to fill.
Depending on how small or large your cookie indents are, you may need a bit less or a bit more lemon curd than called for in the recipe.
Storage
Cooled cookies can be stored in an airtight container on the counter for up to five days. They can also be stored sandwiched between parchment paper in a container in the freezer for up to one month.
