Biscoff Rice Krispie Treats

Lisa Flinn
These soft and chewy Biscoff Rice Krispie Treats are not your average rice krispie cereal bars! Rich cookie butter and a hint of cinnamon is infused in every gooey bite. The treats are topped with a layer of melted chocolate that's swirled together with melted cookie butter, and then finished with Biscoff cookies.

INGREDIENTS

Biscoff Rice Krispies

  • 5 Tablespoons (70g) Unsalted Butter
  • 10 Ounce Bag (283g)  Mini Marshmallows, divided (save 1 cup to mix in at the end)
  • ½ Cup (135g) Cookie Butter
  • ½ Teaspoon Vanilla Paste or Extract
  • ¼ Teaspoon Cinnamon (otional)
  • Pinch of Salt
  • 3 ½ Cups (98g) Rice Krispies Cereal

Topping (Optional)

  • 5 Ounces (140g) Semi-Sweet Chocolate Bar finely chopped & melted
  • 3 Tablespoons (50g) Cookie Butter melted
  • Biscoff Cookies

Instructions
 

  • Prep Pan - Lightly butter an 8x8-inch pan, and line it with parchment paper, leaving an overhang for easy removal.
  • Make Biscoff Rice Krispies - In a large pot, and over medium-low heat, melt butter completely.
    5 Tablespoons (70g) Unsalted Butter
  • With the heat still on medium-low, add mini marshmallows (reserve 1 cup for later), cookie butter, vanilla, cinnamon and salt. Using a silicone spatula, stir until completely melted.
    10 Ounce Bag (283g)  Mini Marshmallows, divided (save 1 cup to mix in at the end)
    ½ Cup (135g) Cookie Butter
    ½ Teaspoon Vanilla Paste or Extract
    ¼ Teaspoon Cinnamon (otional)
    Pinch of Salt
  • Off heat, add the rice cereal and mix until everything is evenly coated. Next, add the reserved mini marshmallows and fold until combined.
  • Press into Pan - Transfer the cereal mixture into your prepared pan. Use a butter wrapper, or greased silicone spatula, and evenly press it into the pan. Don't pack it down too firmly or the bars will be too hard.
  • Decorate (Optional) - Add finely chopped chocolate into a heatproof bowl. You can either melt it in the microwave in 15-second intervals (stirring in between) or over a small pot of simmering water. Once melted, set aside.
    5 Ounces (140g) Semi-Sweet Chocolate Bar
  • Next, microwave the cookie butter in 5-second intervals until melted.
    3 Tablespoons (50g) Cookie Butter
  • Using an offset spatula or back of a spoon, spread the melted chocolate on top of the treats in an even thin layer. Then drizzle the melted cookie butter over the chocolate layer. Use a toothpick or knife and swirl the layers together. Finally, firmly press some Biscoff cookies on top if desired.
  • Let Set - Now the hard part! Let the chocolate/cookie butter layer set completely at room temperature, which takes about 3 hours. Once they're set, lift them out using the parchment sling and slice into squares. Enjoy!
