Ingredients

Scale
  • 1/2 cup (110g) unsalted butter, melted
  • 1/2 cup (150g) cookie butter*
  • 1 cup (185g) dark brown sugar
  • 1 large egg
  • 2 tsp vanilla extract
  • 1 1/2 cups (200g) all-purpose flour
  • 1/2 tsp cinnamon
  • 1/4 tsp salt
  • 68 speculoos cookies (e.g., Lotus Biscoff), broken into pieces

*Cookie butter is a spiced cookie spread like Biscoff spread.


Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. In a large bowl, mix together the melted butter, cookie butter, and dark brown sugar with a rubber spatula. Cookie butter is thick, so press and fold as needed until smooth.
  3. Add the egg and vanilla extract. Mix until the mixture is glossy and smooth.
  4. Add the flour, cinnamon, and salt. Mix until a thick cookie dough forms.
  5. Press the dough evenly into the prepared pan, spreading to the edges.
  6. Sprinkle the broken speculoos cookie pieces over the top, gently pressing them into the surface.
  7. Bake for 25–30 minutes, or until the center is no longer sticky and appears matte.
  8. Let cool in the pan at room temperature for 20 minutes, then chill in the fridge for 30–45 minutes to firm up.
  9. Once set, lift the bars out using the parchment and slice into squares. Enjoy!

Notes

  • Chilling after baking is crucial for clean slices—don’t skip it!
  • You can add white chocolate chips or chopped nuts for a twist.
  • Store in an airtight container at room temperature for up to 4 days or refrigerate for up to 1 week.
