Puppy Chow is a long time favorite dessert recipe that you can eat by the handful! Chex cereal coated in chocolate, peanut butter, and powdered sugar is a classic, and super simple to make.
In a heat proof bowl, combine the butter, chocolate and peanut butter together and melt them in the microwave. Remove from the microwave, add vanilla extract and stir to combine.
Add Rice Chex to a large bowl, then pour the chocolate peanut butter mixture over the cereal.
Stir until the cereal is evenly coated in the chocolate.
Allow the chocolate to cool down slightly (but not harden).
Put the cereal mixture into a large ziploc bag, sprinkle with powdered sugar and mix until well combined.
