How to Make Biscoff Blondies (Step-by-Step)

Step 1: Prep your pan and oven
Preheat your oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper, letting some hang over the edges for easy removal.

Step 2: Mix the wet ingredients
In a medium bowl, whisk the melted butter and brown sugar until combined. Add the egg, vanilla extract, and salt. Stir until smooth.

Step 3: Fold in flour
Add the flour and mix until no dry streaks remain.

Step 4: Add Biscoff and cookies
Gently fold in the Biscoff cookie spread and chopped Biscoff cookies. You can swirl the spread slightly to create a marbled effect.

Step 5: Bake
Transfer the batter into the prepared pan and spread it evenly. Bake for 23–27 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out mostly clean.

Step 6: Cool and slice
Let the blondies cool in the pan for 15–20 minutes before lifting them out. Slice into 9 or 16 bars, depending on your preference.

Expert Tips for Perfect Blondies

• Don’t overmix the batter. Overmixing can make blondies cakey instead of chewy.
• Slightly underbake for gooey centers. They’ll continue to cook in the pan.
• Let them cool. Cutting them too early leads to messy bars — patience is worth it!
