Follow these simple steps to create your delicious Biscoff Brownies:

1. Preheat Your Oven: Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal.

2. Melt the Butter: In a medium saucepan over low heat, melt the butter completely. Remove it from heat and let it cool slightly.

3. Combine Sugar and Eggs: In a large bowl, pour the melted butter over the granulated sugar. Mix well until fully combined. Add eggs, one at a time, whisking until smooth.

4. Add Vanilla: Stir in the vanilla extract to enhance the flavors of the mixture.

5. Mix Dry Ingredients: In another bowl, sift together the flour, cocoa powder, baking powder, and salt. Gradually add this mixture to the wet ingredients. Stir until fully combined.

6. Fold in Cookie Crumbs: Gently fold in the Biscoff cookie crumbs, semi-sweet chocolate chips, and chopped Biscoff cookies, ensuring they are evenly distributed in the batter.

7. Pour into Pan: Pour the batter into the prepared baking pan and spread it evenly.

8. Bake: Place the pan in the preheated oven and bake for 25-30 minutes. Test for doneness by inserting a toothpick in the center; it should come out with a few moist crumbs.

9. Cool: Remove from the oven and let the brownies cool in the pan on a wire rack for 15-20 minutes.

10. Slice and Serve: Once cool, lift the brownies from the pan using the parchment paper. Cut into squares and serve.
