Heath Bar Puppy Chow ~Some people call them Muddy Buddies, some people get mad at me and tell they think these are for dogs. But I have to admit, I love calling them puppy chow and I love making it because itâs SO EASY. In 6 minutes you can be done, start to finish. No waiting for the oven to preheat, or waiting for the timer to buzzânone of that! Just melt, mix, shake and pour. Puppy Chow recipes get a ton of traffic and rave reviews. So I thoughtâ¦throw in some pieces of toffee and itâs even better!
