Lemon Biscoff Bars

Preheat the oven to 350ºF. Grease an 8 x 8 pan. Set aside.

In the bowl of a food processor, pulse the cookies until coarsely ground. Add the brown sugar, salt, and melted butter. Process until a ball of dough starts to form.

Transfer the dough to the prepared 8 x 8 pan and press it evenly across the entire bottom of the pan. Bake for 20 minutes.

While the crust bakes, prepare the filling by whisking together the eggs, sugar, flour, baking powder, lemon juice, and lemon zest.

Once the crust is finished baking, immediately pour the filling over the crust and continue baking for 20-25 minutes, until set and golden at the edges. Cool completely before slicing.
