09 - 3/4 cup Biscoff cookie butter (smooth or crunchy)
10 - 8 Biscoff cookies, roughly chopped

# How to Make It:

01 - Preheat the oven to 350°F. Line a 9x9-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a medium saucepan, melt the butter over medium heat. Continue cooking, stirring constantly, until the butter foams and turns golden brown with a nutty aroma (about 4-5 minutes). Immediately pour into a large mixing bowl to prevent burning. Let cool for 5 minutes.
03 - Whisk in the brown sugar and granulated sugar until well combined.
04 - Add the eggs and vanilla extract, whisking until smooth and glossy.
05 - Sift in the flour, baking powder, and salt. Fold gently with a spatula until just combined—do not overmix.
06 - Spread the batter evenly into the prepared pan.
07 - Warm the Biscoff cookie butter in the microwave for 15-20 seconds until easily pourable. Drizzle dollops over the blondie batter, then use a knife or skewer to gently swirl it through the top.
08 - Sprinkle the chopped Biscoff cookies evenly over the surface.
09 - Bake for 22-26 minutes, or until the edges are golden and the center is just set (a toothpick should come out with moist crumbs).
10 - Cool completely in the pan before lifting out and slicing into squares.

# Expert Tips:

01 -
  • The brown butter creates this incredible depth of flavor that makes people think you spent hours on something that actually comes together in under an hour
  • That Biscoff swirl running through the middle means every single bite has pockets of creamy, spiced cookie butter heaven
  • The texture is this perfect balance of chewy edges and a center that practically melts in your mouth
02 -
  • Do not skip the step of cooling your brown butter before adding the eggs or you will end up with scrambled eggs in your batter
  • These continue baking as they cool in the pan, so pulling them out when the center still looks slightly underdone is actually correct
  • Room temperature ingredients really do make a difference in how smoothly everything comes together
03 -
  • Chill your Biscoff cookies in the freezer for 15 minutes before chopping so they break into clean pieces instead of crumbling into dust
  • Run your knife under hot water and wipe dry between slices for perfectly clean cuts that look bakery worthy
