Use a food processor to grind the Biscoff cookies. The finer the grind, the smoother cookie texture!
1 cup Biscoff Cookies
Mix the flour, cookie grind, Baking soda, salt, and Speculaas spice to the butter mixture in two or three passes.
Scrape the bottom of the bowl to make sure all dry ingredients incorporated. Divide the dough into two discs, wrap them in cling wrap and refrigerate for at least an hour.
Preheat the oven to 350F, line two baking sheets with parchment paper or baking mat, and set them aside.
Lightly dust a working surface and your rolling pin with flour. Roll out the dough to ¼ inch thickness. If you have difficulty rolling the dough, put the dough between two pieces of parchment paper and roll it out.
½ cup All-purpose flour
Dip the cookie stamp into the flour and press the dough hard to create a defined imprint.
