One bite is never enough of this crispy, crunchy, sweet and salty snack-dessert hybrid. It keeps for awhile, unless you eat it all (not that I have done this ;) ), and be sure to save the clumpy pieces for yourself - they are crazy good with tons of peanut butter hiding inside. —Laura Dembowski
In a large microwave safe bowl, place peanut butter and chips. Microwave in 30 second increments, stirring in between, until fully melted. Stir in vanilla. Add Reese’s Pieces and 4 cups of cereal. Stir to fully coat in the peanut butter mixture. Add more cereal, 1 cup at a time, until there is not too much gooey peanut butter in the bowl, but the mixture is not dry. I used about 6 cups of cereal. I do not recommend using more than that.
Pour sugar, 1 cup at a time, onto cereal. Stirring and adding more sugar as needed until it is fully coated. How thick the coating of sugar depends on your preferences. I used 4 cups. Puppy chow may be stored in an airtight container at room temperature for up to 1 week.
