Ingredients
  

  • ½ cup butter salted butter, melted
  • 1 egg
  • ¾ cup dark brown sugar lightly packed
  • 2 teaspoons vanilla extract
  • 2 teaspoons cinnamon
  • ⅓ cup Biscoff cookie butter
  • ¾ cup all-purpose flour

for the topping

  • ¼ cup butter salted, softened
  • ½ cup old fashioned rolled oats not quick oats or instant oatsnot quick oats or instant oats
  • ¼ cup packed brown sugar
  • 2 tablespoons sugar
  • 2 tablespoons all-purpose flour
  • 1 teaspoon cinnamon
  • 2 tablespoons Biscoff cookie butter reserved for the drizzle

Instructions
 

  • Preheat your oven to 350°F (175°C). Spray a 8x8 inch baking pan with nonstick cooking spray then line it with parchment paper, then set it aside.
  • In a large bowl, whisk together the melted and cooled butter, egg, dark brown sugar, vanilla extract, cinnamon, and Biscoff cookie butter until smooth and well combined.
  • Gradually add the flour to the wet ingredients, stirring until just incorporated. Be careful not to overmix.
  • Spread the batter evenly into the prepared baking pan, using a spatula to smooth the top.
  • Mix the softened butter, oats, brown sugar, sugar, all-purpose flour and cinnamon in a bowl with your fingers until it is crumbly.
  • Sprinkle this over the bars and bake in a 350-F oven for about 30 minutes or until an inserted toothpick comes out mostly clean.
  • Let cool in the pan for 20 minutes, then melt the reserved cookie butter in a small dish in the microwave until melted.
  • Transfer the melted cookie butter to a zipper-top baggie with one corner snipped off. Use the baggie as a piping bag to drizzle the melted cookie butter over the top of the bars.
  • Let cool, then cut into squares and enjoy!

Notes

Chef Jenn's Tips

  • For extra crunch, try adding chopped nuts such as pecans or almonds to the streusel topping.
  • Don't skip the step of greasing the baking pan, as it will make it easier to remove the bars once they're baked.
  • Allow the bars to cool completely in the pan before slicing to ensure clean cuts. For perfect cuts, partially freeze the bars before cutting.
