These coconut lemon bar cookies have a chewy & buttery coconut cookie with a rich lemon curd filling. They are incredibly flavorful, refreshing, and there is no dough chilling!
In a medium sauce pan, combine the granulated sugar and egg yolks. Whisk them together until smooth and combined. Add the lemon zest and lemon juice and whisk until combined.
Place the pan over the stove on low-medium heat and stir constantly while it heats up. The mixture will begin to thicken and bubble. Once it begins to bubble, it should be done. If you have a thermometer, it should be about 160F.
Remove from the heat and add the cubed butter. Stir until the butter has completely melted and the mixture is combined.
Strain the lemon curd into a bowl and get rid of the lemon zest. Cover it with cling wrap/tin foil that is placed directly onto the curd. This will prevent a film on the top of the lemon curd from forming. Let it cool at room temperature while making the cookies.
Cookie
Preheat the oven to 350F and line a baking sheet with parchment paper.
In a medium-sized bowl, whisk together the flour, cornstarch, baking powder and salt. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, or a large bowl if using a handheld mixer, beat the butter and cream cheese together on medium-high speed until smooth and no lumps remain. With the mixer on low-medium speed, stream in the granulated sugar and beat on medium-high speed until combined and fluffy, about 1-2 minutes.
Add the egg, egg yolk, vanilla extract, and coconut extract and mix on medium speed until combined. Add the dry ingredients and mix on low speed until a dough forms, scraping down the bottoms and sides of the bowl as necessary. It will be thick and sticky.
Fill a small bowl with granulated sugar and another small bowl with powdered sugar.
Using a large cookie scoop, approximately 3 tablespoons, scoop the cookie dough and immediately place it in the granulated sugar. Toss to coat - immediately placing the scooped cookie dough into the granulated sugar will prevent the dough from sticking to your hands.
Roll the dough into a ball with your hands and toss in the powdered sugar - coat it generously. Place on the lined baking sheet, spacing the cookies about 3 inches apart. The cookies will spread in the oven.
Using a rounded tablespoon, press the bottom of the tablespoon into each cookie until it forms a round indent. Place a heaping teaspoon of curd into the indent. Bake the cookies for 11-13 minutes until the cookies are set and the curd is bubbling up. It will set when the cookies are cooling.
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a cooling rack to cool completely. Dust with additional powdered sugar if desired. Enjoy!
