Ingredients for peanut butter rice krispie treats.
  • Unsalted butter
  • Creamy peanut butter— I used Jif No Sugar Added Creamy Peanut Butter. Any kind of peanut butter or other nut butter should be fine to use. Keep in mind some nut butters have a higher oil content and may make your treats a bit stickier. 
  • Miniature marshmallows— you can substitute with an equal amount of regular-sized marshmallows if you prefer.
  • Vanilla extract
  • Rice Krispies cereal— any brand of rice cereal will work. A 9 ounce box will give you more than enough cereal for this recipe.
  • Semisweet chocolate chips— these treats are quite sweet so I do recommend sticking with semisweet chocolate. Dark chocolate would also be delicious! 
  • Peanut butter baking chips— I used Reese’s baking chips. 
  • Coconut oil or vegetable shortening— this ingredient helps the chocolate melt smoothly. I have found that both coconut oil and vegetable shortening work really well here. 

Supplies

Nothing fancy here. Just your typical baking supplies.

For this recipe you will need:

  • Measuring cups and spoons

How to Make Peanut Butter Rice Krispie Treats in the Microwave

No stovetop, no worries! In a pinch, you can make these bars using only your microwave!

  1. Add the butter and marshmallows to a large microwavable bowl.
  2. Microwave for 1-minute intervals on 50% power, stirring in between each interval until smooth and combined.
  3. Stir in the peanut butter and vanilla, followed by the Rice Krispies.
  4. Press into a prepared 9 x 13 pan and follow the directions in the recipe card to prepare the topping.

Tips for the Best Peanut Butter Rice Krispie Treats

  • Extra chocolatey treats. Try making your bars with cocoa krispies cereal instead for added chocolate flavor.
  • Don’t overcook the marshmallows. Remove the marshmallows from heat as soon as they are melted and smooth. They will become hard if you overcook them.
  • Grease up your hands. It is much easier to press the mixture into the pan if you spray your hands with non-stick cooking spray first or seperate your hands from the sticky rice cereal mixture with a sheet of parchment or wax paper. This will help to keep the sticky rice cereal mixture from sticking to them.
  • Don’t press down too hard. It may be tempting to press down really firmly on the peanut butter cereal mixture, but please don’t. It will cause the bars to become too dense and firm.
  • Slice quicker with this shortcut. If you are in a hurry to slice your bars you can set the pan in the refrigerator to help the topping set up quicker.
  • Choose your size. These peanut butter dessert bars are perfect for serving up at parties or celebrations. We typically slice them up into 12 large bars but you could totally cut them into smaller bars to stretch them out for a party or event. Especially if you are serving them up to kids.

Frequently Asked Questions

Do rice krispies treats need to be refrigerated?

No. Refrigerating these treats will make them dry and hard so I recommend storing them at room temperature. 

How do I keep these treats from becoming hard?

To prevent hard rice krispie treats make sure you don’t overcook your marshmallows. Remove them from the heat as soon as they are completely melted. Also, make sure you don’t press too hard when spreading them in the pan. When you press them in too hard they can become very dense and hard. Finally, store them at room temperature in an airtight container. 

Can you freeze Peanut Butter Chocolate Rice Krispies Treats?

Yes! While they taste best fresh, these tasty treats can be frozen in an airtight container or freezer bag for up to 2 months. Before freezeing, place a piece of parchment or wax paper between layers to prevent sticking.

Are Rice Krispies gluten-free?

Kellogg’s Rice Krispies are not gluten-free when purchased in the United States. If you want to make these treats gluten-free use a brand of crispy rice cereal that is gluten-free such as Malt-o-Meal, One Degree, or Nature’s Path. (And make sure all your other ingredients are GF as well.)
