Ingredients

Scale

Brownie Batter

  • 1 cup salted butter
  • 1 ½ cups granulated sugar
  • ½ cup packed brown sugar
  • 4 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup all-purpose flour
  • 1 cup unsweetened cocoa powder
  • 1 cup semi-sweet chocolate chips
  • 1 cup crushed Biscoff cookies (folded into the batter)

Cookie Butter Swirl & Topping

  • ½ cup Biscoff cookie butter, slightly warmed
  • 810 whole Biscoff cookies, for topping

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper and lightly spray it with non-stick spray to prevent the brownies from sticking.
  2. Melt Butter and Combine Sugars: Melt the salted butter in a saucepan over low heat. Whisk in the granulated sugar and brown sugar until the mixture is smooth and glossy. Let it cool slightly to avoid cooking the eggs.
  3. Add Eggs and Vanilla: Whisk in the eggs one at a time along with the vanilla extract, mixing well until the batter is silky smooth and fully combined.
  4. Mix Dry Ingredients: Stir in the all-purpose flour and unsweetened cocoa powder just until the batter comes together. Stop mixing as soon as no dry flour is visible to ensure fudgy brownies.
  5. Fold in Chocolate Chips and Crushed Cookies: Gently fold the semi-sweet chocolate chips and most of the crushed Biscoff cookies into the batter, reserving a small amount of crushed cookies for topping if desired.
  6. Pour and Spread Batter: Pour the batter evenly into the prepared pan, spreading it out smooth and flat for even baking.
  7. Swirl Cookie Butter: Warm the Biscoff cookie butter until it is soft enough to spoon easily. Drop small spoonfuls over the brownie batter and gently swirl with a knife to create a marbled effect.
  8. Add Whole Cookies: Press 8 to 10 whole Biscoff cookies evenly spaced on top of the batter for an attractive and crunchy topping.
  9. Bake: Bake in the preheated oven for 30 to 35 minutes, or until the edges are set but the center remains soft and fudgy. Avoid overbaking to keep the brownies moist.
  10. Cool and Slice: Allow the brownies to cool completely in the pan before slicing to achieve thick, clean squares.

Notes

  • Ensure the melted butter mixture is not too hot before adding eggs to prevent curdling.
  • Do not overmix the batter once flour is added to maintain fudginess.
  • Use room temperature eggs for better incorporation.
  • For easier slicing, chill the brownies after cooling.
  • Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
