A quick, no-bake snack mix where Rice Chex gets coated in a silky blend of melted chocolate and peanut butter, tossed with crushed Butterfinger bars, and finished with a snowy layer of powdered sugar. Perfect for parties, movie nights, or gifting.
Pour the Rice Chex cereal into a large mixing bowl and set aside. Line a baking sheet with parchment for cooling.
In a microwave-safe bowl, combine the chocolate chips, peanut butter, and butter. Microwave in 30-second increments, stirring after each, until fully melted and smooth (about 60–90 seconds total).
Stir in the vanilla extract, then pour the warm mixture over the cereal. Gently fold with a spatula until all cereal pieces are evenly coated.
Add the crushed Butterfinger bars and fold again to distribute the candy throughout the coated cereal.
Transfer the mixture to a large zip-top bag (or lidded container). Add the powdered sugar, seal, and shake until the cereal is thoroughly coated and no glossy spots remain.
Spread the puppy chow on the parchment-lined baking sheet to cool and set, about 10–15 minutes. Serve or store airtight.
