🍴 Recipe Tips
Making peanut butter crispy treats is pretty simple but there are a few things to note.
- Greasing your pan can be done with butter or nonstick cooking spray.
- When you press the Krispies into the pan, it really helps to have your hands greased too. This prevents it from sticking. So either rub softened butter on your hands or spray your palms with cooking spray.
- When you're melting the marshmallows, it's important to do it over a low temperature and to stir as little as possible to avoid overworking the marshmallows. It's okay to stir, but you don't need to do it constantly (except for when you melt in the peanut butter and add the cereal- that's different).
ANOTHER GREAT TIP: You can make these peanut butter rice crispy treats DAIRY FREE with the use of a plant based butter! Just double check the ingredients list on the back of the cereal box as some may contain traces of milk.
If you melt your marshmallows over too high of a heat you're cooking them too much and that will result in a much harder square when you're done. If you leave it on low, it might take a few extra minutes, but it's so much more worth it for the perfect tender treat we want.
You can use either one for these peanut butter crispies! Personally, I like the creamy peanut butter because it's what we have on hand, but if you want a little extra grit then chunky peanut butter works great.
While the two are very similar, they aren't exactly the same. Pescotcheroo bars have butterscotch chips melted into the peanut butter cereal bars for a unique flavor and there's melted chocolate on top. You can see for yourself with my Scotcheroos Recipe over here.
Absolutely! Just grab a large mixing bowl (microwave safe) and heat your butter and peanut butter for about 30 seconds until melted. Add in the marshmallows and heat for about 2 minutes, stirring at the 1 minute mark. Add in the cereal and combine. Pour into a baking dish and let set.
Take a bag of chocolate chips and place them in a microwave safe bowl with 3 tablespoons of coconut oil or heavy cream. Heat for 30 seconds, stir, and then another 30 seconds, repeating until they're completely melted.
Pour over the top of the crispy bars in the baking dish and let the top harden. You can speed this process up by placing them in the freezer for a few minutes.
