Melt mini-marshmallows with butter by microwaving for a minute and a half, stirring, and then 30 seconds at a time until melted completely.
Line a cookie sheet with parchment paper and lightly spray with cooking spray. Stir melted marshmallows together with 6 cups of Fruity Pebbles. Pour onto cookie sheet and spread out.
Melt chocolate chips in a glass microwave safe bowl by microwaving for one minute, stirring, and then in 30 second increments (stirring in between) until melted.
Pour melted chocolate over the cereal bars and spread so evenly dispersed.
Let sit for a few hours until chocolate has hardened, or leave overnight.
Variations:
) Reduce chocolate by as much as ¼ and drizzle over cereal bars instead of spreading over.
) Replace the chocolate chips with white chocolate chip using either the same amount the original recipe calls for and spreading over the cereal bars or a reduced amount and drizzling over the cereal bars.
