Ingredients

Scale
  • 1 cup unsalted butter
  • 1 cup Biscoff cookie butter
  • 1 cup brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup white chocolate chips
  • 1/2 cup crushed Biscoff cookies

Instructions

1. Preheat your oven to 350°F (175°C) and grease a 9×9-inch square baking pan or line it with parchment paper.

2. In a medium saucepan, melt the unsalted butter and Biscoff cookie butter over low heat, stirring occasionally until smooth and fully combined.

3. Remove the saucepan from heat and let the mixture cool slightly for about 5 minutes.

4. Add the brown sugar and whisk until fully combined and smooth.

5. Add the eggs and whisk until completely incorporated.

6. Stir in the vanilla extract.

7. In a separate bowl, sift together the flour, baking powder, and salt.

8. Slowly stir the dry ingredients into the wet mixture using a spatula or wooden spoon. Do not overmix.

9. Fold in the white chocolate chips and crushed Biscoff cookies until evenly distributed.

10. Pour the batter into the prepared pan and spread it evenly with a spatula.

11. Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.

12. Cool the blondies in the pan for about 10 minutes, then transfer to a wire rack to cool completely.

13. Once cooled, cut into squares and serve.

Notes

Allow the melted butter and Biscoff mixture to cool before adding sugar to avoid cooking the eggs.

Fold in the white chocolate chips and crushed cookies gently to maintain the blondie texture.

For a gooier blondie, reduce baking time slightly. Add a pinch of cinnamon to the dry ingredients for enhanced Biscoff flavor.
