Step 1

Place chocolate and peanut butter in a large microwave-safe bowl. Microwave for 1 minute and stir until melted. If not melted enough, microwave for another minute and stir again. Repeat until completely melted.

Step 2

Add the cereal and mix until completely coated.

Step 3

Transfer the puppy chow onto a baking sheet lined with parchment or wax paper. Spread the pieces in a single layer to avoid them from sticking. Let it sit for several minutes for the chocolate to dry.

Step 4

Pour powdered sugar into a large ziplock bag. Add the coated cereal, seal, and shake until coated.

Step 5

Store puppy chow in an airtight container.
