1 1/4 sticks softened unsalted butter
1/2 cup sugar
1 large egg at room temperature
1 1/2 tsp. lemon zest
1/2 tsp. vanilla extract
2 cups sifted all-purpose flour
2 T. toasted almond flour
1 cup confectioners’ sugar
3 T. ground freeze-dried raspberries (optional)

In a large bowl and using an electric mixer at medium-high speed, beat butter and sugar together until light and fluffy, about 5 minutes. Beat in egg, lemon zest, and vanilla extract; scrape down sides of bowl. In a small bowl, combine all-purpose flour and almond flour. Slowly add flours to butter mixture, beating until dough just comes together. Remove dough from bowl, shape into a disk, wrap tightly with plastic wrap, and refrigerate for 2 hours. Preheat oven to 350°. Line 2 baking sheets with parchment paper; set aside. On a lightly floured surface, roll dough to just thinner than 1/4 inch. Using various sizes of heart-shaped cutters, cut about 3 dozen cookies, rerolling dough only once, if necessary. Carefully transfer cookies to baking sheets; bake for 7 to 10 minutes, or until edges just turn golden. Cool on baking sheets for 5 minutes, then transfer to a wire rack to cool completely. In a small bowl, sift together confectioners’ sugar and ground raspberries, if desired. Dust cookies lightly with sugar.
