Those look great. We love snacks like this. Anything with chocolate and peanut butter. My SO likes to cook and make snacks. There are times when we both go on diets to make up for indulgences.
We used to double the amount of peanut butter and used a whole bag of chocolate chips and the entire box of Chex. That’s why we called it Garbage rather than Puppy Chow, it was too much for a ziplock bag so we’d get a garbage bag and mix it in that.
It’s also fun to add in things. We used to add in raisins, but you can add in marshmallows or pretzels or whatever.
