Enjoy summer in a bite with these lemon bar cookies! These buttery cookies are pillowy soft and have a tart, creamy pool of lemon curd baked into the center. Dusted with powdered sugar, they taste exactly like a lemon bar in cookie form!
In a large bowl with an electric hand mixer or in the bowl of a stand mixer fitted with the paddle attachment, cream the butter and sugar together on medium-high speed until light and fluffy.
1 cup unsalted butter, ¾ cup granulated sugar
Add the egg yolk and vanilla extract. Beat on medium-high until well combined.
1 egg yolk, 2 teaspoon vanilla extract
Gradually mix in the flour ½ cup at a time on low until fully combined. Then mix in the salt.
2 ¼ cup all purpose flour, ½ teaspoon salt
Chill the cookie dough for 20 minutes. While it chills, preheat the oven to 350°F/180°C and line 2 cookie sheets with parchment paper.
Use a medium cookie scoop to portion the dough. Roll each scoop into balls.
Drop each ball into a bowl of powdered sugar, rolling it around until evenly coated. Place the balls 1-2 inches apart from each other on the lined baking trays.
¾ cup powdered sugar
Use the bottom of a teaspoon to press down on top of the dough to create a well. Fill the well with 1 heaping teaspoon of lemon curd.
½ cup lemon curd
Bake the cookies for 12-14 minutes until the edges are set and the lemon curd is bubbly.
Remove from the oven and let the cookies cool on the hot tray for 5 minutes.
Transfer the cookies to a wire rack and let them cool completely. Dust with more powdered sugar and enjoy!
