🧂 Ingredients Needed
- butter - gives your treat bars a nice buttery flavor and helps the marshmallows form a decent consistency to stick to the cereal.
- peanut butter - adds a distinct salty, nutty, and slightly sweet flavor that takes your rice krispie treats to the next level.
- mini marshmallows - a classic ingredient in these treat bars, melting marshmallows is what helps form the bars.
- crispy rice cereal - a light cereal with a mild flavor that pairs well with sweet and salty flavors.
- Place butter and peanut butter in a large saucepan or large pot over the stove top.
- Stir frequently until melted and combined.
- Add mini marshmallows.
- Stir until well incorporated and melted.
- Over low heat, stir the cereal into the mixture until evenly coated.
- Press in an even layer into a 8x8 prepared pan with cooking spray or butter, and allow your treats to sit for at least 2 hours to come up to room temperature.
The number one cause of hard rice krispie treats is cooking the butter and marshmallow mixture at too high a heat. You'll want to melt all of the ingredients together low and slow to ensure that the sugar in the marshmallows doesn't become tough when it cools.
As a substitute, you can use some almond butter or even more peanut butter. The consistency of the finished product may be slightly different than without the marshmallows, but the treats should still be able to hold their shape.
Too much butter can lead to soggy or greasy rice krispie treats, or they may be too loose to hold together. On the other hand, not enough butter can lead to a dry result. You may need to experiment to determine how much butter is optimal for how you like yours!
💭 Expert Tips and Tricks
- Don't rush the melting process, use medium heat or low heat to ensure everything comes together smoothly. This will prevent burning and also prevent your peanut butter rice krispie treats from becoming too hard.
- For an even easier time getting your treats out of the pan, line with some parchment paper or wax paper.
- Fresh marshmallows will yield far superior results than old or stale ones. If you have marshmallows laying around, this probably isn't the best recipe for them! Buy a nice fresh bag for best results.
- Don't press the cereal mixture into the pan too hard, as this can lead to compact and hard treats.
📌 For a simple and foolproof dessert, make these peanut butter rice krispie bars! Great to pop into a lunchbox, to snack on for a boost in the afternoon, or as a sweet and salty post-dinner treat!
💡 Substitutions and Variations
- For some extra sweetness and flavor, add a dash of vanilla extract.
- Stir extra mini marshmallows in with the cereal for fluffy pockets in your cereal treats.
- This recipe was made with smooth peanut butter in mind, but you could also try using crunchy or your favorite all natural peanut butter. Be aware that results may vary.
- Additional topping ideas: mini chocolate chips (semi-sweet chocolate chips work great) or melted chocolate, peanut butter chips, powdered sugar, colored sprinkles, butterscotch chips, flaky salt or sea salt, or a squeeze of frosting.
🥫 Storage and Reheating
Keep your rice krispies treats with peanut butter in an airtight container at room temperature for 3-4 days. As time goes on, they may get harder or stale, so be sure to enjoy them as close to fresh as possible.
You can also freeze them for up to 6 months by storing them in a freezer safe bag. Be sure to let them sit out at room temperature before eating, the freezer will make them hard!
