Aimee’s Recipe Notes
It’s no secret around here that classic rice krispie treats are my favorite dessert. And a runner up would be my scotcheroos. So why not combine the two for a tasty treat!
I’ve got a lot of tips on keeping them fresh and flavorful, soft and chewy.
Adding peanut butter just upped the flavor and is perfect for the PB lover in your life. Drizzle with chocolate, go ahead. It’s worth it.
ENJOY!

First, start with FRESH marshmallows. And be sure to reserve 1 cup of the mini marshmallows to add later.
e sure to use a shelf stable peanut butter (avoid natural peanut butters that separate with oils). Add in rice krispies cereal and stir until blended. Fold in remaining mini marshmallows.
Pour mixture into a parchment paper lined 9-inch square baking dish. DO NOT press them in tightly. Allow to set one hour. Cut and enjoy.
How to Store Rice Krispie Treats
Keep peanut butter krispie treats in an airtight bag or covered in pan on counter at room temperature. These will stay fresh for about 5 days.
You can FREEZE krispie treats too. I was skeptical at first, but the taste and texture once thawed is delicious. Just be sure to use a freezer safe container (I use gallon size freezer bags).

Peanut Butter Rice Krispie Treats Recipe
Ingredients
- ¼ cup unsalted butter
- 16 ounce mini marshmallows, divided
- ½ cup creamy peanut butter
- 6 cups Rice Krispies cereal
Instructions
- In a large pot, melt butter over medium heat. Add all but one cup of the mini marshmallows, turn heat to low, and continue cooking and stirring until marshmallows are melted.
- Remove from heat and stir in peanut butter. Add in rice krispies cereal and stir until blended. Fold in remaining mini marshmallows.
- Pour mixture into a parchment paper lined 9-inch square baking dish. DO NOT press them in tightly. Allow to set one hour. Cut and enjoy.
Notes
- Using parchment paper is a great way to remove your krispie treats from the pan.
- Use fresh marshmallows. Don’t think that any marshmallows will work, especially the hard ones in the back of your pantry. USE FRESH.
- Choose a regular brand of creamy peanut butter, NOT a natural version. The natural peanut butters tend to have too much oil.
- DO NOT (I repeat) DO NOT press these bars into your pan firmly. Using your fingertips, GENTLY press them in just until they are spread out. The harder you pack them in, the harder they are when it’s time to eat them!
- The trick to pressing them in your pan without sticking to your hands is to run your fingers in water, shake off the excess, and press. Voila. No sticking!

Hi Aimee. I am looking for a recipe for Nutella krispie treats. Do you think it would work to just use Nutella in place of the peanut butter in your peanut butter krispie treats recipe? Thanks for your thoughts. Jean F
I don’t have a specific Nutella recipe, but I think swapping out the peanut butter is a great place to start!

These look so amazing! I love Rice Krispy treats and adding PB sounds like a genius idea to me.
