Ingredients

Scale

Brownie Batter

  • 1 cup salted butter
  • 1 ½ cups granulated sugar
  • ½ cup brown sugar, packed
  • 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 and Topping

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

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F. Line a 9×13 inch baking pan with parchment paper and lightly spray it to prevent sticking.
  2. Melt butter and mix sugars: Melt 1 cup of salted butter in a saucepan over low heat. Whisk in 1 ½ cups granulated sugar and ½ cup packed brown sugar until the mixture is smooth and glossy. Allow it to cool slightly to avoid cooking the eggs in the next step.
  3. Add eggs and vanilla: Whisk in 4 large eggs and 2 teaspoons vanilla extract until the mixture is well combined and silky smooth.
  4. Incorporate dry ingredients: Stir in 1 cup all-purpose flour and 1 cup unsweetened cocoa powder just until the batter comes together. Be careful to stop as soon as dry spots disappear to keep the brownies fudgy.
  5. Fold in chocolate chips and cookies: Gently fold 1 cup semi-sweet chocolate chips and 1 cup crushed Biscoff cookies into the batter, reserving a bit of the crushed cookies for topping if desired.
  6. Pour batter into pan: Transfer the brownie batter into the prepared pan, spreading it out evenly with a spatula.
  7. Add cookie butter swirl: Warm ½ cup of Biscoff cookie butter until spoonable, then drop small spoonfuls across the surface of the batter. Use a knife to gently swirl the cookie butter into the brownie batter.
  8. Add cookie topping: Press 8 to 10 whole Biscoff cookies evenly spaced on top of the brownies.
  9. Bake: Bake for 30 to 35 minutes, until the edges are set and the center remains soft and fudgy but not wet.
  10. Cool and serve: Allow the brownies to cool completely before slicing to achieve thick, clean squares perfect for serving.

Notes

  • For extra fudgy brownies, avoid overmixing the flour and cocoa powder into the batter.
  • Warming the Biscoff cookie butter slightly makes it easier to swirl into the batter.
  • Use parchment paper to ensure easy removal and clean edges when slicing.
  • Store leftover brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
  • For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend.
