Place Crispix into a large container with plenty of extra room.

Place butter, chocolate chips, and peanut butter in a microwave-safe container. Microwave one minute at a time, stirring after each minute until the mixture is smooth.  (If the chips don’t fully melt, let sit for several minutes, then beat the mixture several times before pouring it over the cereal.

When pouring, it’s best to drizzle over the surface while tossing, then get into the mixture and thoroughly toss together with clean hands (gloves would be great, here) until all cereal is coated.

Add the powdered sugar to a large paper grocery bag, close tightly with several folds, and, supporting the bottom of the bag, shake. Turn upside down once or twice while shaking. Pour onto a sheet tray, attempting to leave excess sugar behind.

Highly Recommended: If desired, once  cooled, add back into the powdered sugar, adding a little more powdered sugar if needed, to double coat.

Optional: For less mess when serving, place puppy chow into a large sieve or colander and give the puppy chow a few gentle shakes; excess sugar sifts out, and tiny bits of cereal accumulate on the bottom and can be removed. Chef snack!

Note: Don’t stress the exact amount of cereal if your package isn’t right on. Either estimate or if it’s in the standard 18 ounces, there’s a generous amount of extra chocolate peanut butter mixture.
