Cookies and Cream Puppy Chow

I’m not gonna lie: just LOOKING at these photos makes me drool. Muddy buddies are my undoing – I can eat an entire batch in one day if I’m not careful. ESPECIALLY if they have peanut butter AND Oreos in them.

I rarely change the original muddy buddy recipe because if it ain’t broke…right? I mean chocolate + peanut butter + Chex cereal…there’s nothing wrong with any of that. In fact, I’ve used this recipe but coated peanut butter pretzels and made muddy buddy pecans with the magical elixir that is the muddy buddy recipe.
