Ingredients

Scale

Blondie Batter

  • ½ cup unsalted butter (melted)
  • ½ cup granulated sugar
  • ¾ cup packed light brown sugar
  • 2 teaspoons vanilla extract
  • 2 large eggs
  • ¼ teaspoon salt
  • 1 cup all-purpose flour
  • ½ teaspoon baking powder

Mix-ins and Topping

  • 10 Biscoff cookies, chopped into chunks
  • 4 oz bar of white chocolate, roughly chopped
  • ½ cup Biscoff cookie butter

Instructions

  1. Preheat and prepare baking dish: Preheat the oven to 350°F (177°C). Line an 8×8 inch glass baking dish with parchment paper, allowing an overhang for easy removal later, and set aside.
  2. Mix wet ingredients: In a large mixing bowl, whisk together the melted unsalted butter, granulated sugar, and light brown sugar until smooth and combined.
  3. Add eggs and vanilla: Whisk in the vanilla extract and eggs until fully incorporated and the mixture is homogenous.
  4. Incorporate dry ingredients: Add the salt, all-purpose flour, and baking powder to the wet mixture. Stir gently just until everything is combined to avoid overmixing.
  5. Add cookie and chocolate chunks: Fold in the chopped Biscoff cookies and white chocolate pieces gently, keeping some chunks aside for topping if desired.
  6. Layer the batter: Spread half of the blondie batter evenly into the prepared baking dish, smoothing the surface.
  7. Swirl Biscoff cookie butter: Microwave the Biscoff cookie butter for about 15 seconds until pourable. Drizzle this evenly over the bottom layer of blondie batter in the baking dish.
  8. Top with remaining batter: Spoon and spread the remaining blondie batter on top of the cookie butter layer, then press the reserved cookie and chocolate chunks gently onto the surface for added texture.
  9. Bake blondies: Bake in the preheated oven for 35-40 minutes or until the tops are golden brown and a knife inserted into the center comes out clean or with only a few moist crumbs. The center should not be wet or raw.
  10. Cool and serve: Allow the blondies to cool completely in the baking dish. Using the parchment overhang, lift the blondies out and transfer to a cutting board. Cut into bars and serve.

Notes

  • For best texture, avoid overmixing the batter once flour is added.
  • If white chocolate chunks are too large, chop smaller to ensure even melting.
  • Biscoff cookie chunks add a delightful crunch; feel free to reserve more for topping.
  • Cooling completely is crucial for clean slicing and maintaining shape.
  • Store blondies in an airtight container at room temperature for up to 3 days or refrigerate for extended freshness.
