How to Make Cookie Butter Blondies
Preheat your oven to 350°F and line a 9x9 pan with parchment paper.
Melt the butter and let it cool slightly while you crush most of the Biscoff cookies for the filling. Break the remaining cookies into larger chunks for topping.
In a mixing bowl, combine the melted butter and brown sugar until smooth. Stir in the cookie butter until fully incorporated.
Add the eggs and vanilla and mix just until combined.
Fold in the flour, baking powder, and salt. Be careful not to overmix — once a few streaks of flour remain, add the crushed cookies and white chocolate chips and gently fold them in.
Spread the batter into your prepared pan. Add four small dollops of cookie butter on top and gently smooth them into the surface.
Bake for 30–35 minutes, until the edges are golden brown and the center is just set.
As soon as they come out of the oven, press the broken cookie pieces on top and sprinkle a few extra white chocolate chips if desired for that bakery-style finish.
Allow to cool before slicing for clean, perfect squares.
Tips for the Best Blondies
Do not overbake. Slightly underbaked blondies = fudgy centers.
Let the butter cool slightly before mixing to avoid scrambling the eggs.
For clean slices, allow the blondies to cool completely.
Add extra white chocolate chips on top right after baking for that melty, picture-perfect look.
If you love thicker blondies, chill the batter for 30 minutes before baking.
Storage
Store in an airtight container at room temperature for up to 4 days. These also freeze beautifully, wrap tightly, and freeze for up to 2 months.
