Introduction

Biscoff blondies are rich, buttery bars with the irresistible flavor of Biscoff cookie butter and a sweet white chocolate twist. These chewy, golden treats are perfect for dessert or a cozy snack with your favorite cup of coffee.

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 (175°C) 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 and 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 (and if desired, a pinch of baking powder, salt, and cinnamon) to the wet ingredients, mixing until just combined. Fold in the white chocolate chips carefully.
Step 4: Pour the batter into the prepared pan and evenly sprinkle the crushed Biscoff cookies on top. Bake for 30 to 35 minutes, or until the blondies are golden and a toothpick inserted in the center comes out mostly clean.
Step 5: Allow the blondies to cool completely in the pan before lifting out and cutting into squares. This helps them set and hold together nicely.

Tips & Variations

For extra gooey blondies, slightly underbake by removing them after 28 minutes and letting residual heat finish cooking.
Swap white chocolate chips with milk or dark chocolate chips for a different flavor profile.
Add a pinch of cinnamon or nutmeg to the batter to enhance the warm spice notes of the Biscoff.
Use a mix of crushed Biscoff cookies and chopped nuts for added texture on top.

Storage

Store blondies in an airtight container at room temperature for up to 4 days. For longer storage, keep them in the refrigerator for up to a week or freeze for up to 3 months. Reheat gently in the microwave for a few seconds to soften before serving.
