Ingredients

  • 1 cup salted butter, melted 226 grams
  • 1/3 cup cookie butter
  • 1 and 2/3 cup light brown sugar, packed
  • 1 large egg
  • 1 large egg yolk
  • 1 tsp vanilla extract
  • 2 cups all-purpose flour
  • 1/4 tsp cinnamon
  • 1/4 tsp salt
  • 1/2 tsp baking powder
  • 1/2 cup biscoff cookie crumbs, plus additional cookies for topping 6-7 cookies
  • 1/2 cup cookie butter, for topping

Instructions

  • Prep: Line a 9x9 pan with parchment paper or spray with nonstick cooking spray. Set aside. Preheat oven to 350° F.
  • Make the Blondies: In a large mixing bowl, melt the butter and whisk in the cookie butter. Whisk in the brown sugar. Whisk in the egg, egg yolk, and vanilla until just combined. Add the dry ingredients biscoff cookie crumbs and stir in until just combined. Spread the batter in your prepared pan. Dollop the remaining 1/2 cup cookie butter over the batter and swirl it in with a knife. Sprinkle on a few more crushed biscoff cookies.
  • Bake: Bake: Bake for 29-33 minutes. A toothpick inserted into the center will have moist crumbs, but not wet wet batter. The edges will appear more set than the center, which will have a slight wobble. Don't over bake these!
  • Serve + Store: Let cool 1-2 hours before cutting. These are amazing while they're still warm from the oven! Store leftovers in an airtight container at room temp for 3-4 days.
