Are you a Peanut Butter fan? If so, you can’t miss trying these yummy Peanut Butter Rice Krispie Treats.
Peanut Butter always adds something special to a dish. And these bars are no exception.

How to Make Peanut Butter Rice Krispie Treats
Peanut butter is super versatile. You can add it to so many different foods to give them that little extra pinch of yum.
I love peanut butter cookies, peanut butter pie, peanut butter on crackers and toast. Besides being yummy, it’s filling and adds a little extra protein to a food.
So, I figured, why not add peanut butter to rice krispie treats and see what we get? Let me tell you, these did NOT disappoint!
If you know how to make Rice Krispie Treats, you’ll be happy to know these are just as simple. Just like with the Butterscotch Rice Krispie Treats, you just add one additional ingredient – peanut butter, of course!
(I got a little crazy after making these because they were so good. And made these Chocolate Peanut Butter Rice Krispie Treats with some of the pan. Whew, are they good, too!)

Step One
Melt and mix together your butter and marshmallows. This can be done via the microwave or on the stove top.
The microwave tends to be a smidge faster and I like to use it when intime crunch. But stove top really doesn’t take too long either.
On the stove top, melt the butter and then add in and melt the marshmallows on low to medium heat.
In the microwave, you can melt both together at once. I usually let it go for one minute at a time. Then stir and check and pop it back in for another minute then repeat until melted.
Step Two
Add the Rice Krispies into the bowl with your melted butter and marshmallow mix.
Step Three
Add in the peanut butter. I highly recommend using creamy peanut butter. Crunchy would leave not a very smooth texture.
Step Four
Stir these four ingredients completely so that the marshmallow and peanut butter mixture coats all of your Rice Krispies.
Step Five
Using a coated (either with butter or non-stick spray) spatula, spread your mixture into a greased pan evenly.
Enjoy Your Peanut Butter Rice Krispie Treats
Finally, you can enjoy your bars! You should let them cool for about 30 minutes before cutting and eating. If you can wit that long!
Storing Peanut Butter Rice Krispie Treats
You can freeze these if you want to make a large batch, or perhaps you have more self-control than I do and don’t eat the whole pan quickly. Freezer bags will do fine and then just stick them in the freezer.
If you’re going to finish them within a week, you’ll want to keep them in an air tight container.
