Ingredients

Scale

Wet Ingredients

  • ½ cup (115g) unsalted butter, melted
  • ¾ cup (150g) brown sugar
  • ¼ cup (50g) granulated sugar
  • 1 large egg, room temperature
  • 1 tsp vanilla extract
  • ½ cup (120g) Biscoff spread (smooth or crunchy)

Dry Ingredients

  • 1 cup (125g) all-purpose flour
  • ½ tsp baking powder
  • ¼ tsp salt

Add-ins and Toppings

  • ½ cup (90g) white chocolate chips or chunks
  • 68 Biscoff cookies, crushed or halved
  • Optional: sea salt flakes
  • Optional: chopped nuts
  • Optional: extra Biscoff spread for drizzling

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper to prevent sticking and make removal easy.
  2. Combine Sugars and Butter: In a mixing bowl, stir together the melted unsalted butter, brown sugar, and granulated sugar until the mixture is smooth and fully blended.
  3. Add Egg and Vanilla: Incorporate the room temperature egg and vanilla extract into the sugar-butter mixture, mixing thoroughly to combine all the ingredients evenly.
  4. Mix in Biscoff Spread: Add the Biscoff spread to the wet ingredients and stir until the mixture is creamy and well blended, ensuring the cookie butter flavor is evenly distributed.
  5. Add Dry Ingredients: Gently fold in the all-purpose flour, baking powder, and salt, mixing just until combined to avoid overworking the batter and preserving a tender texture.
  6. Incorporate Add-ins: Fold in the white chocolate chips and half of the crushed Biscoff cookies to the batter for bursts of flavor and texture.
  7. Prepare for Baking: Pour the batter into the prepared baking pan and smooth the surface with a spatula. Dollop extra Biscoff spread on top and swirl with a knife for a marbled effect. Sprinkle the remaining cookie pieces evenly over the top.
  8. Bake: Place the pan in the preheated oven and bake for 25–30 minutes, or until the edges turn golden and the center is just set but still moist for a chewy texture.
  9. Cool and Serve: Allow the blondies to cool completely in the pan before slicing into squares. For an extra special touch, drizzle melted Biscoff or white chocolate over the top before serving.

Notes

  • Ensure all ingredients are at room temperature to achieve smooth mixing and even baking.
  • For extra gooey blondies, slightly underbake and let them set as they cool in the pan.
  • Variations include adding chopped pecans, swirling cream cheese into the batter, or substituting dark chocolate chips for white chocolate for a different flavor profile.
  • Store baked blondies in an airtight container at room temperature for up to 5 days, or freeze for up to 2 months to maintain freshness.
  • Allow blondies to cool completely before slicing to achieve clean edges and the best texture.
