The image shows a single square piece of a peanut butter dessert bar on a white plate. The bar has three layers: the bottom layer is a dense, brown textured crust, the middle layer is a smooth, creamy light brown peanut butter filling, and the top layer is a slightly darker peanut butter drizzle with three large white chocolate chips embedded in it. The surface has a slightly glossy and swirled look, with some peanut butter drizzled over the top. The background is a white marbled texture. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

¾ cup unsalted butter
½ cup Biscoff cookie butter
1 cup brown sugar
½ cup granulated sugar
2 large eggs
2 cups all-purpose flour
⅔ cup white chocolate chips
Crushed Biscoff cookies for topping

Instructions

Step 1: Preheat your oven to 350°F and prepare a 9” x 9” square pan by spraying it with cooking spray and lining it with parchment paper.
Step 2: Melt the unsalted butter, then combine it with the Biscoff cookie butter, brown sugar, granulated sugar, and eggs in a mixing bowl. Stir until smooth and well blended.
Step 3: Gradually add the all-purpose flour, mixing until just combined. Then fold in the white chocolate chips carefully to distribute them evenly.
Step 4: Pour the batter into the prepared pan, smoothing the top, and sprinkle crushed Biscoff cookies evenly over the surface.
Step 5: Bake for 30 to 35 minutes, or until the blondies are golden and a toothpick inserted into the center comes out with a few moist crumbs.
Step 6: Allow the blondies to cool completely in the pan before cutting into squares and serving.

Tips & Variations

For extra gooey blondies, slightly underbake them and let them finish setting as they cool.
Swap white chocolate chips for milk or dark chocolate chips if preferred.
Add a pinch of cinnamon or nutmeg to the batter for a warm spice note.
Use a mix of crushed Biscoff cookies and chopped nuts for added crunch on top.

Storage

Store cooled blondies in an airtight container at room temperature for up to 4 days. You can also refrigerate them to extend freshness for up to a week. To reheat, warm a blondie in the microwave for about 10 seconds to restore softness.

FAQs

Can I use regular peanut butter instead of Biscoff cookie butter?

While peanut butter can work, it will change the flavor profile significantly. Biscoff cookie butter provides a unique caramelized spice flavor that defines these blondies.

Can I freeze Biscoff blondies?

Yes, you can freeze them for up to 3 months. Wrap them tightly in plastic wrap and place in a freezer-safe container. Thaw at room temperature before serving.
