Method
- In a large bowl using a hand mixer or stand mixer, beat the room-temperature butter and 1 cup of confectioners' sugar together on medium-high speed for 2-3 minutes until light and fluffy.1 cup unsalted butter, 1 cup confectioners' sugar
- Add the egg, vanilla extract, and lemon zest to the butter mixture. Beat for about 1 minute until well combined, scraping down the sides of the bowl as needed.1 large egg, 1 teaspoon pure vanilla extract, 1 tablespoon lemon zest
- In a separate bowl, whisk together the all-purpose flour, cornstarch, and salt.½ teaspoon cornstarch, ⅛ teaspoon salt, 2 ¼ cups all-purpose flour
- With the mixer on low speed, gradually add the dry ingredients to the wet ingredients, mixing until just combined and a soft dough forms.
- Cover the bowl and chill the dough in the refrigerator for at least 60 minutes, or up to 3 days.
- Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
- Scoop out tablespoon-sized portions of the chilled dough and roll them into balls. Place the dough balls about 2 inches apart on the prepared baking sheets.
- Use your thumb or the back of a ½ teaspoon measuring spoon to make a deep indentation in the center of each dough ball.
- Fill each indentation with about ½ to 1 teaspoon of lemon curd.⅓ - ½ cup lemon curd
- Place the filled cookie trays in the freezer for 10-15 minutes while the oven finishes preheating.
- Bake the cookies for 10-12 minutes, until the edges are just barely starting to turn golden. The centers will still be soft.
- Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
- Once completely cool, dust the cookies lightly with the remaining confectioners' sugar before serving.2 tablespoons confectioners' sugar
Notes
Success Tips: Do not skip the chilling steps! Chilling the dough prevents the cookies from spreading and helps them hold the lemon curd filling. For the best flavor, use high-quality lemon curd or make your own. The unbaked dough can be refrigerated for up to 3 days or frozen for 2 months, making it a great make-ahead option. These cookies are also delicious filled with other jams or fruit curds.
