In a medium saucepan over low heat, melt the Biscoff® and chocolate, stirring constantly until completely melted. Remove from heat.
Immediately pour melted mixture over cereal and stir gently to coat.
Pour cereal into a large zip-top bag or large container with a tight-fitting lid and add the powdered sugar. Shake until everything is coated. Spread onto baking sheet lined with foil or parchment and allow to cool. Discard excess powder. Store in an airtight container at room temperature up to one week.
