5 cups whole-grain cereal squares
2 cups bittersweet chocolate chips
⅓ cup smooth natural peanut butter
1 tablespoon vanilla extract
2 tablespoons confectioners' sugar
Line a baking sheet with wax paper or a nonstick baking mat. Place cereal in a large bowl.
Heat chocolate chips in a medium saucepan over medium-low heat, stirring frequently, until melted. Add peanut butter and stir to combine. Remove from heat and stir in vanilla. Pour the mixture over the cereal; gently stir until evenly coated. Transfer to the prepared baking sheet and spread in an even layer. Refrigerate until the chocolate has hardened, about 30 minutes.
Gently break the puppy chow into bite-size pieces. Place the confectioners' sugar in a fine-mesh sieve and sprinkle over the mixture. Toss to coat.
