Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a small bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.

In a large bowl, cream together the butter, granulated sugar, and light brown sugar until fluffy.

Add the egg and vanilla to the creamy mixture and mix until well incorporated.

Fold in the Biscoff spread until combined.

Gradually add the dry mixture to the wet ingredients, mixing until just combined. Fold in the M&M's.

Portion the dough onto the prepared baking sheet, spacing about 2 inches apart, and lightly press down each dough ball.

Bake for 12-14 minutes until edges are golden brown, let cool on the baking sheet for 10 minutes before transferring to a wire rack.
