How To Make the Biscoff Blondies

Step 1: Prep and Preheat

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper and lightly grease.

Step 2: Mix the Wet Ingredients

In a large bowl, whisk together the melted butter and brown sugar until smooth. Add the Biscoff spread, egg, and vanilla extract, whisking until fully combined.

Step 3: Fold in the Dry Ingredients

Add the flour, baking powder, and salt to the bowl. Stir until just combined. Then fold in the chopped Biscoff cookies.

Step 4: Bake the Blondies

Pour the batter into the prepared pan, spreading evenly. Sprinkle a few extra Biscoff cookie pieces on top. Bake for 22–25 minutes or until the edges are set and the center is slightly soft.

Step 5: Cool and Slice

Let the blondies cool completely in the pan before slicing into squares. They firm up as they cool, making them easier to cut.
