01 - Line a baking sheet with parchment paper. Scoop 12 heaping teaspoons of Biscoff spread onto the sheet and freeze for at least 30 minutes until solid.
02 - Preheat oven to 350°F and line another baking sheet with parchment paper.
03 - In a large bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy.

05 - In a separate bowl, whisk together the flour, baking soda, and salt.
06 - Gradually add the dry ingredients to the wet mixture, mixing just until combined.
07 - Gently fold in the white chocolate chips and crushed Biscoff cookies.
08 - Scoop 2 tablespoons of dough per cookie. Flatten slightly in your palm, place a frozen Biscoff ball in the center, and wrap dough around to seal completely.
09 - Arrange stuffed dough balls on the prepared baking sheet 2 inches apart. Refrigerate for 15 minutes.
10 - Bake for 11 to 13 minutes until edges are golden and centers are just set. Cool on the tray for 5 minutes before transferring to a wire rack.
