Ingredients
Method
Preparation
- In a medium bowl, whisk together the all-purpose flour, almond flour, and salt; set aside.
- In the bowl of a stand mixer, cream the softened butter and granulated sugar together on medium speed until light and fluffy, about 3–4 minutes.
- Reduce mixer speed to low, add the egg yolk, vanilla extract, and lemon zest, mixing until just combined.
- Gradually add the dry ingredients into the butter mixture on low speed until just combined. The dough should be soft and pliable.
- Divide the dough into two portions, flatten into discs, wrap in plastic wrap, and refrigerate for at least 1 hour.
Baking
- Preheat oven to 350°F (175°C). On a floured surface, roll one disc of dough to about 1/8 to 1/4 inch thickness.
- Cut out cookies using a fluted round cookie cutter and a smaller cutter for the tops. Place on prepared baking sheets.
- Bake for 8–10 minutes. Allow to cool on baking sheets for 5 minutes before transferring to a wire rack.
Making the Lemon Curd
- In a heatproof bowl, whisk together lemon juice, sugar, whole eggs, and egg yolks. Place over simmering water and whisk continuously until thickened, about 8–10 minutes.
- Remove from heat and whisk in the cold diced butter until melted and fully incorporated, then stir in lemon zest.
- Pass the curd through a fine-mesh sieve into a bowl and cover directly with plastic wrap. Refrigerate until thickened.
Assembly
- Dust the tops of the cut-out cookies with powdered sugar.
- On a whole un-dusted cookie, spoon 1–2 teaspoons of lemon curd, spreading it gently.
- Top with the powdered-sugar-dusted cookie to create a sandwich.
Notes
Store assembled cookies in an airtight container layered with parchment for up to 5 days. Unassembled cookies can be frozen for up to 3 months.
