From Start to Finish: Muddy Buddy (Puppy Chow) Marshmallow Cereal Treats

Step 1: Prepare Your Baking Dish
Begin by lining your 9×13-inch baking dish with parchment paper. This ensures easy removal of the treats once they’re set.
Step 2: Melt Chocolate Mixture
In a microwave-safe bowl, combine the semisweet chocolate chips, creamy peanut butter, and salted butter. Microwave in 30-second intervals, stirring in between, until everything is completely melted and smooth. This should take about 1 to 2 minutes total.
Step 3: Add Vanilla
Once the mixture is smooth, stir in the vanilla extract until fully incorporated.
Step 4: Mix in Marshmallows and Cereal
In a large mixing bowl, combine the miniature marshmallows and Rice Chex cereal. Pour the melted chocolate mixture over the cereal and marshmallows, and gently fold everything together until all the Rice Chex are evenly coated.
Step 5: Transfer to Baking Dish
Spoon the mixture into your prepared baking dish. Use the rubber spatula to spread it out evenly and press it down gently to compact it.
Step 6: Let It Set
Allow the mixture to cool at room temperature for about 30 minutes or until it is firm enough to cut into squares.
Step 7: Dust with Powdered Sugar
Once set, lift the treats out of the baking dish using the parchment paper. Dust the top generously with powdered sugar, then cut into squares or bars.
