Melt the Chocolate Mixture
In a medium saucepan (or microwave-safe bowl), combine semi-sweet chocolate chips, creamy peanut butter, and butter.
Heat over low heat, stirring frequently, until smooth and glossy.
Remove from heat and stir in vanilla extract.
You’ll know it’s ready when it smells like a Reese’s cup melted down into perfection.
Coat the Cereal
Pour Rice Chex cereal into a large bowl.
Slowly pour the warm chocolate mixture over the cereal, stirring gently with a spatula until every piece is evenly coated.
Pro tip: Don’t crush the cereal — gentle folding is key! Each square should be lightly chocolate-coated and shiny.
Add the Powdered Sugar
Now for the fun part!
Transfer the coated cereal into a large zip-top bag (or use two gallon-sized bags if needed).
Add powdered sugar. Seal the bag tightly and shake until everything is evenly coated and fluffy white.
(If you’re making this with kids, this is their favorite part — and honestly, adults love it too.)
Cool & Serve
Spread the coated cereal out on a baking sheet lined with parchment paper.
Let it cool for about 10 minutes until the chocolate sets.
Then, dig in! Store leftovers (if you somehow have any) in an airtight container at room temperature.
