Preheat oven to 375°F (190C).
In a large bowl, add the butter, cookie butter, vanilla extract, and both sugars. Whisk with a hand or stand mixer on medium speed for about 2 minutes or until creamy.
Mix in egg.
Mix in the flour, baking soda, baking powder, and ground Biscoff cookies. Stir well until a batter forms.
Gently fold in the white chocolate chips.
Place the dough in the refrigerator for a few minutes if it's too soft. Once the dough is firm enough to scoop, scoop out 9 equally sized cookie dough balls using a cookie scoop or tablespoon.
Place the cookie dough balls on the cookie tray and bake for 9-11 minutes.
Remove the cookies from the oven and allow them to cool on a cooling rack.
