Prepare Ingredients:
Measure out the Rice Krispies cereal, chocolate chips, peanut butter, unsalted butter, and vanilla extract. Have everything ready before starting.

Melt Chocolate and Peanut Butter:
In a microwave-safe bowl, melt the chocolate chips and peanut butter in 30-second intervals. Stir after each interval until smooth and completely melted.

Combine Ingredients:
Add the melted butter and vanilla extract to the melted chocolate-peanut butter mixture. Stir until the mixture is well combined.

Mix with Rice Krispies:
In a large mixing bowl, combine the Rice Krispies cereal with the chocolate-peanut butter mixture. Gently fold until the cereal is evenly coated with the mixture.

Spread and Cool:
Spread the coated cereal mixture onto a baking sheet or into a pan, pressing down gently. Allow it to cool and set for about 1 hour before cutting into squares.

Add Powdered Sugar:
Once cooled, transfer the bars into a large resealable plastic bag. Add the powdered sugar to the bag, seal it, and gently shake to coat the bars. Alternatively, you can lightly dust the bars with powdered sugar for a prettier presentation.

Serve and Enjoy:
Cut the Muddy Buddy Rice Krispies into squares and enjoy! These bars are perfect for snacking or serving at a party.
