Start by gathering all your ingredients and equipment. Line a baking sheet with parchment paper if desired.
In a microwave-safe bowl, combine the Biscoff spread and your choice of almond bark or white chocolate chips. Heat in the microwave in 30-second intervals, stirring in between, until smooth and fully melted.
In a large mixing bowl, add the Chex cereal. Pour the melted Biscoff and chocolate mixture over the cereal, gently folding it with a spatula until all the cereal pieces are evenly coated.
Once the cereal is fully coated, sprinkle the powdered sugar over the mixture. Stir gently to combine.
Crumble the Biscoff cookies into small pieces and sprinkle them over the coated cereal, mixing again to distribute evenly.
Spread the Cookie Butter Muddy Buddies out onto the prepared baking sheet and allow them to cool for about 30 minutes.
