01 - Line a baking sheet with parchment paper. Scoop 12 teaspoons (about 1 heaping teaspoon each) of Biscoff spread onto the sheet. Freeze for at least 30 minutes until solid.
02 - Preheat oven to 350°F. Line another baking sheet with parchment paper.
03 - In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
04 - Beat in the egg and vanilla extract until well combined.
05 - In a separate bowl, whisk together the flour, baking soda, and salt.
06 - Gradually add the dry ingredients to the wet, mixing just until combined.
07 - Fold in the white chocolate chips and crushed Biscoff cookies.
08 - Scoop 2 tablespoons of dough per cookie. Flatten slightly in your hand, place a frozen Biscoff spread ball in the center, and wrap the dough around it, sealing completely.
09 - Place stuffed dough balls onto the prepared baking sheet, spacing 2 inches apart. Chill in the fridge for 15 minutes.
10 - Bake for 11-13 minutes, or until edges are golden and centers are just set. Let cool on the tray for 5 minutes, then transfer to a wire rack. Enjoy warm for maximum lava effect.
