Fudgy Chocolate Peanut Butter Rice Krispie Cups

I had a half-empty bag of Rice Krispies left from a breakfast experiment, a jar of peanut butter staring at me from the pantry shelf, and a handful of chocolate chips that had survived my midnight snacking. The thought of bringing all three together felt both playful and promising.

The first batch came together in less than 20 minutes, and I remember leaning against the counter, waiting for them to cool, sneaking bites before the chocolate even had time to set. The balance was exactly what I wanted: fudgy and creamy from the peanut butter, crisp and airy from the cereal, and that glossy chocolate top that makes you feel like you’ve pulled off something way fancier than you actually did.

These cups instantly reminded me of after-school snacks nostalgic, comforting, but dressed up just enough to feel like a treat worthy of sharing with friends or bringing to a party. Since then, I’ve been tweaking the little details, adding sea salt here, adjusting chocolate there, and I can confidently say this recipe is a keeper.

It’s quick enough for a busy weekday, kid-friendly if you want to involve little helpers, and versatile enough to adapt for health-conscious eaters or those who prefer an extra fudgy bite. And the best part? They look picture-perfect in their little muffin liners, ready to impress with zero stress.

Tools Needed

Cooking Instructions

Step 1: Melt the Base
In a medium saucepan, melt butter and mini marshmallows over low heat, stirring constantly until smooth and gooey.
