Ingredients

  • 6 Tablespoons butter* (85 g)
  • 1 - 10 oz bag mini marshmallows
  • ¾ cup + 2 Tablespoons Biscoff spread (210 g), also known as cookie butter spread
  • 5 cups crispy rice cereal (150 g) such as Rice Krispies
  • 10 pieces Biscoff cookies (80 g), roughly chopped

Optional Topping:

  • ¼ cup Biscoff spread (60 g)

Instructions

  • Line 8-inch or 9-inch square baking pan* with parchment paper. Allow excess paper to hang over the sides. The overhang will help with unmolding. Set aside.
  • In a large pot, melt butter over medium heat. Add marshmallows. Stir until marshmallows have melted. Reduce to low heat. Add Biscoff spread and stir until melted and thoroughly combined.
  • Remove from heat and immediately add in rice cereal and chopped Biscoff cookies. Fold to combine until cereal and cookies are completed coated in the marshmallow mixture.
  • Transfer cereal mixture to prepared baking pan. Press the cereal mixture into an even layer. Cool to room temperature, about 30 minutes.
  • Use parchment paper overhang to lift and unmold rice krispies treats from the pan. Place on a cutting board. Use a sharp knife to slice into desired serving sizes.
  • Optional Topping: Place Biscoff spread in a microwave safe bowl. Heat in 10-15 second intervals, stirring each time, until mixture easily drips off the spoon. Drizzle liquid over the cut rice krispies treats.

Notes

Work quickly when folding the cereal into the melted marshmallow mixture. It will become more difficult to stir the contents together as the marshmallow cools and hardens. 
Ingredients:
  • This recipe works with either salted or unsalted butter. When using unsalted butter, I like to add a pinch of salt to the melted butter. 
  • For more complex flavor, brown the butter before adding the marshmallows! 
  • Mini marshmallows melt faster and more evenly than the larger marshmallow sizes.
Storage and Leftovers:
  • The optional cookie butter drizzle will not harden or set. Keep this in mind if you plan to stack the treats.
  • Store leftovers in an airtight container for up to 4 days. Overtime, it will stale and harden.
