These peanut butter rice krispie bars are a classic childhood favorite given a delicious twist! They’re so full of peanut butter flavor and topped with a pinch of flaky salt to make them mouthwatering that you may never want to eat a regular rice krispie treat again!
To be honest with you, I never understood why everyone was so obsessed with adding flaky salt to, like, ALL of the things. Why would you want to do that? Well…. I tried it ( bought this flaky salt off of Amazon for like 6 bucks! It’ll last like forever haha)… and I get it now. It’s freaking DELICIOUS. And I have the worlds biggest sweet tooth, let me tell you that. So if I am saying do it, do it.
What You need For This Peanut Butter Rice Krispie Treat Recipe
You only need a few ingredients to make these peanut butter rice krispies bars of heaven:
- Rice Krispies cereal (or off brand puff rice- both work!)
- Marshmallows (large or mini work, honestly)
- Butter
- Creamy peanut butter
- Vanilla
- Flaky salt
These are basically PB bars of heaven. They’re like an easier version of my “scotcheroos” or “Special K Bars” recipe. Except those are made with slightly different ingredients and have layer of chocolate butterscotch on top!
And, I’ll also just tell you right now, if you’re here because you’re a peanut butter lover like myself, you MUST try my small batch peanut butter cookies and my almond flour peanut butter cookies!
How To Make Salted Peanut Butter Rice Krispie Bars
First, lightly spray a 9×9 baking pan with non-stick spray, then create a “sling” with parchment paper (good visual of how to create a parchment paper sling here) and then lightly spray again with parchment paper.
Now, in a large pot melt together the butter and marshmallows, stirring continuously.
Once butter and marshmallows are totally melted and the mixture is uniform, remove from heat and add in your peanut butter and vanilla, mixing well.
Next, fold in your rice krispie cereal into the warm peanut butter marshmallow mixture. Continue folding until it is evenly coated. Be careful not to do this too aggressively, you don’t want to totally crush your rice krispies!
Pour your warm, coated rice krispies into the prepared baking dish and press down lightly so they are in one even layer.
Top with a pinch of flaky sea salt and lightly press down over the top of the bars, so the sea salt sticks.
Allow the bars to cool fully, then spray a large knife with non-stick spray and cut into squares. I like to make mine nice and big, so I cut them in to 9 squares, but you can totally do smaller! Enjoy!
Peanut Butter Rice Krispie Treats Recipe FAQ
Can I use other types of cereal?
Absolutely! I love making fun rice krispie treats! Well, they aren’t really rice krispie treats if you don’t use rice krispies, are they? I love doing captain crunch, cocoa pebbles or even corn flakes would work!
Can I use something other than butter to make these vegan?
If you want to sub out the butter you could try coconut oil. I haven’t tested this but I bet it would work. You can also find vegan marshmallows, like the ones from Trader Joe’s! Then, obviously check your cereal to make sure that is vegan, whatever kind you decide on!
How do I store these?
You can store these in an airtight container for 5-7 days. You can totally also throw them in the freezer for a few months, however mine never make it that far. HAHA!
