Lemon Thumbprint Cookies (adapted from Glorious Treats)
3/4 cup (1 1/2 sticks) unsalted butter
1/2 cup powdered sugar (plus a little extra for dusting the finished cookies)
1/4 cup sugar
1 teaspoon fresh lemon zest
1 Tablespoon fresh lemon juice
1 teaspoon vanilla
1 teaspoon baking powder
2 cups all purpose flour
3/4 cup prepared lemon curd ( I made my own curd)
Beat butter in a large bowl until smooth. Add sugars and continue mixing. Add egg, lemon zest, lemon juice and vanilla. Mix until fully incorporated. Add baking powder, and then flour (slowly, while mixing). Stop mixing as soon as the flour is fully incorporated. Cover dough and chill in the refrigerator about 1 hour.
Place lemon curd into a small ziplock bag, and cut off one corner of the bag.
When the dough has chilled, preheat oven to 350*F. Roll small balls of dough and place on a silpat lined, or parchment lined baking sheet. Flatten balls of dough slightly with the palm of your hand. Use your thumb to create a crater in the center of the dough. Fill crater with about 1 teaspoon of lemon curd.
Bake cookies about 15 minutes, or until cookie edges are just turning golden brown. Remove from oven, cool slightly, then move to a wire cooling rack to cool fully. Dust cookies with powdered sugar.
Lemon Curd Recipe:
1/4 cup fresh lemon juice (usually requires 1-2 lemons)
2 teaspoons finely grated lemon zest
1/3 cup sugar
4 egg yolks
3 Tablespoons butter (I use unsalted)
Combine all ingredients in the top of a double boiler (or in a metal bowl over a pot of simmering water). Heat, while stirring (almost) constantly with a whisk, until mixture thickens. It is done when it’s thick enough to coat the back of a spoon. Remove from heat, cover and refrigerate until cool. Store in the refrigerator up to 2 weeks.
(Note- I found that when I dusted the cookies with powdered sugar, the sugar fully covered the lemon filling. I wanted the filling to show up a bit, so I dipped one finger into a small bowl of water, then just slightly moistened the lemon filling. Then, sprinkle with powdered sugar, and the sugar will only be visible just the cookie portion.)
Recipe yields about 3 dozen cookies
