"Muddy buddies" and "puppy chow" are two different names for the same sweet treat. The name varies from region to region, but the recipe is generally the same. The name "Puppy Chow" comes from the dessert's likeness to dog food, but rest assured, pistachio puppy chow is crafted with humans in mind. And the treat is perfect for parties, gatherings, or a single-serving snack for you to enjoy.
