Rice Krispie treats already feel like a childhood classic — simple, sticky, and hard to stop at one square. Peanut butter takes that base and pushes it even further. You get chewy, slightly gooey treats with a nutty flavor that makes them feel a little richer and a little more grown up.
They’re still as easygoing and snackable as you remember, but the peanut butter pulls in a warmth that gives the simple cereal bars a deeper flavor. A quick mix, a short set in the pan, and you’re cutting into something that hits that snack sweet spot just right.
What Makes Peanut Butter Rice Krispie Treats So Good
It’s the texture and the balance of flavors that set these apart from plain ones.
The cereal stays crisp and light, while the peanut butter adds a creamy richness that coats every puff without making it heavy. Marshmallows bring the sticky, stretchy sweetness that pulls it all together, but peanut butter keeps it from being one-dimensional sweet. Every bite gives you chewy, crispy, creamy, and sweet in just the right ratio.
- Marshmallow base keeps them chewy and slightly gooey
- Peanut butter adds depth and smooth richness
- Rice cereal stays light and crisp
- No oven, just a quick stovetop melt
- Sets quickly so you can slice and snack sooner
Perfect for after-school snacks, casual get-togethers, or late-night sweet cravings.
What You’ll Need to Make It

How to Make Peanut Butter Rice Krispie Treats
Nothing fancy — just a few quick moves on the stovetop, then you’re setting it in the pan.
- Melt Butter and Marshmallows
In a large pot, melt butter over low heat. Add mini marshmallows and stir until completely melted and smooth. - Add Peanut Butter and Vanilla
Remove the pot from heat. Stir in the peanut butter and vanilla until smooth and fully blended. - Fold in the Cereal
Gently fold the cereal into the warm mixture, stirring until everything is evenly coated. Work quickly while it’s still warm and easy to move. - Press Into Pan
Pour the mixture into a greased or parchment-lined 9×13 pan. Press gently with a buttered spatula or clean hands — don’t press too hard, or they’ll turn out dense. - Cool and Slice
Let them cool completely at room temperature. Slice into squares once firm and ready.

How to Store Them the Right Way
These bars keep their texture if you store them the right way — no need to worry about them getting dry too fast.
- Store at Room Temperature – Best texture when kept loosely covered on the counter.
- Use Wax Paper Between Layers – Stops them from sticking together if stacking.
- Best Within 3–4 Days – After that, they lose a little softness but still taste good.
- Freeze for Longer Storage – Wrap individually and freeze for up to 2 months; thaw at room temperature.
- Avoid Refrigerating – Makes them too firm and hard to bite through.
FAQs About Peanut Butter Rice Krispie Treats
Can I use natural peanut butter?

What’s the trick to soft, chewy bars?
Melt marshmallows gently over low heat and avoid pressing the cereal mixture too hard into the pan.
Can I add more peanut butter?
You can — just be careful not to add too much, or the treats can turn overly soft and greasy.
How do I make them gluten-free?
Use a certified gluten-free crisp rice cereal and double-check your marshmallow brand.

Swap the butter for plant-based butter to make them fully dairy-free without changing the flavor much.
