Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.

In a large mixing bowl, cream the butter and powdered sugar together until smooth and creamy.

Add the vanilla extract and mix to combine.

In a separate bowl, whisk together the all-purpose flour, almond flour, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing just until a dough forms.

Roll out the dough on a lightly floured surface to about 1/8-inch thickness.

Cut out an even number of cookies using a scalloped round cookie cutter. Use a smaller shape cutter (like a bunny) to cut out the center of half the cookies.

Place the cookies on the prepared baking sheets and chill for 10 minutes.

Bake for 8-10 minutes, or until the edges are just starting to turn golden.

Cool cookies completely on a wire rack.

Spread a teaspoon of lemon curd on the flat side of each whole cookie. Top with a cut-out cookie and gently press to sandwich together.

Dust generously with powdered sugar before serving.
