Ingredients and substitutions
- Cereal - Rice krispies cereal (or a generic brand) serves as the base of this recipe. Rice krispies can be substituted with chex cereal (I suggest rice chex or corn chex) for a similar result.
- Marshmallows - I prefer using mini marshmallows in rice krispies treats because they melt easily, but large marshmallows will also work.
- Butter - Unsalted or salted butter works in this recipe. If using salted butter, cut the listed salt in half.
- Salt - Enhances the flavor of the rice krispies treats. I don't recommend omitting the salt for the best flavor.
- Peanut butter - Creamy peanut butter works best in this recipe. Feel free to use your favorite brand. I like Creamy Jif.
- Oreo cookies - You'll need about 16 oreo cookies for this recipe, which is about half of a standard pack of cookies.
Tips and tricks
Pan size - You'll need a 9x13 rectangular baking pan for this recipe. They could also be prepared in a 9x9 square pan to make extra thick rice krispies treats.
Mise en place - The term mise en place is a French culinary term that refers to the gathering of ingredients and setup required before cooking. Measure your ingredients and have your 9x13 pan lined before you begin.
Work quickly - The marshmallow mixture cools off and thickens quickly, so it's important to work fast. Mix your ingredients and press them into the pan quickly before the mixture cools and becomes difficult to stir.
How to make rice krispies treats less sticky - Your cereal mixture will be sticky once mixed. There are a few methods that can help to painlessly press your bars into the pan. Using either your hands or a large spatula, spray with cooking spray or dampen with water before pressing your bars down. Both methods help reduce stickiness.
Storage
Peanut butter oreo rice krispies treats are best enjoyed within 1 to 2 days of preparing and dry out quickly after that. Store prepared treats in a tightly sealed container at room temperature.
They also freeze well, up to six weeks or more when stored in optimal conditions. I suggest tightly wrapping your treats in foil, then storing in a tightly sealed freezer-safe container or bag.
Frequently asked questions
I don't recommend making rice krispies treats more than one day ahead of time for best results. If you plan to make your bars ahead, leave the slab whole instead of slicing into bars and storing individually. Storing as a whole slab helps retain moisture in your bars.
Yes, a bag of mini marshmallows could be substituted with a jar of marshmallow fluff if desired.
This happens when the ingredients are cooked at too high a heat or cooked for too long on the stovetop. All you're doing is melting the ingredients, not cooking them. There's no need to simmer or cook the ingredients over high heat.

Notes
- Storage: Rice krispies treats will keep for about two days in a tightly sealed container at room temperature. Leftovers can be frozen for up to three months.
- Make ahead: If making ahead, store rice krispies treats slab whole and slice the day of serving. Slicing and storing separately will dry out treats faster than leaving whole.
