Perfect Peanut Butter Rice Krispies Treats Are Sure To Be Your New Favorite!
No-bake desserts are some of my favorites, especially when the weather is hot, and I don’t want to turn on the oven. Not only are they simple to prepare, but they come out delicious every time!
Who doesn’t love Rice Krispies Treats? They're ooey, gooey, and chewy! Absolute perfection! I have been making (and enjoying!) these easy cereal treats for as long as I can remember, and kids today enjoy them just as much!
While the classic version never goes out of style, my Peanut Butter Rice Krispie treats are extra-special, made with creamy peanut butter to add more richness and flavor to every bite.
If you are a fan of peanut butter and have a sweet tooth, these no-bake cereal treats will be right up your alley! Although they are easy to make, you will need a little over 2 hours before you can devour them. The treats need time to chill and firm up before you can slice them into portions and serve.
Sneak in a spoonful of peanut butter if you get impatient!
🥘 Ingredients
My recipe makes 12 servings, but it all depends upon how large or small you cut the treats. Sometimes I make minis and other times I go for the “jumbo” size.
The ingredients list isn’t long, and if you have made Rice Krispies Treats before, you know it does not take much to make a delicious dessert!
- Butter – The hint of saltiness makes these treats well-balanced and buttery.
- Marshmallows – The mini-marshmallows melt better and mix into the cereal with ease.
- Vanilla Extract – Adds flavor and a nice aroma.
- Peanut Butter – Creamy works well, but if you are a fan of chunky, give it a go. Experiment with a flavored peanut butter too.
- Rice Krispies Cereal – The “Snap, Crackle, Pop” that never fails to please!
You'll need a bit more butter for your 9x13 baking pan, non-stick cooking spray works too. Or you can line the pan with a sheet of parchment paper for easy removal of the entire slab of cereal treats.
