Ingredients
Method
- Preheat oven to 350°F (175°C). Line an 8×8 pan with parchment.
- Melt butter and chocolate together; stir until smooth.
- Whisk in sugars, then eggs and vanilla.
- Fold in flour, cocoa, salt, and baking powder.
- Spread half the batter in pan. Add dollops of cookie butter.
- Top with remaining batter and swirl more Biscoff on top.
- Sprinkle crushed cookies. Bake 28–32 minutes.
- Cool fully before slicing.
Notes
For extra fudgy brownies, bake on the shorter end of the time.
Chill for 30 minutes before cutting for cleaner slices.
Store covered at room temperature for 2–3 days or refrigerate up to 5 days.
