There are those of us in this world that like peanut butter, and then there are those who REALLY LIKE PEANUT BUTTER! My husband is one of those true peanut butter lovers. We buy our peanut butter from the bottom shelf of the grocery store, and there is no snacky need that a spoonful of peanut butter can’t fix. For true peanut butter lovers, a simple peanut butter bread will not do. That’s where this recipe for Peanut Butter Swirl Bars comes in.
A Quick, Easy, and Simple Dessert
This recipe combines the forever favorite flavor combination of peanut butter and chocolate, but it adds an extra element all-too-important for true peanut butter lovers: the peanut butter swirl. The best part though? This is a no bake peanut butter dessert! That’s right! You don’t have to turn your oven on at all. Just some melting with the help of a double boiler, plus some time to chill in the fridge makes for a delicious simple dessert!

What Do I Need to Make Peanut Butter Swirl Bars:
- Peanut Butter: These are called Peanut Butter Swirl Bars after all! A standard smooth peanut butter works best in this recipe. I haven’t tried it with a natural peanut butter, but I don’t think it would work as well.
- Graham Cracker Crumbs: You can buy graham crackers whole and crush them, but I prefer to buy them pre-crushed. I’ve tried lots of generic brands, but Honey Maid really does yield the best results for me consistently. There are few things that I purchase brand name, but graham cracker crumbs are one of them!
- Confectioners Sugar: Also known as icing sugar, depending where you’re from. This combines with the graham cracker crumbs and peanut butter to form the base layer of the bar.
- Salted Butter: I use salted butter in this recipe because the salt compliments the peanut butter nicely and yields a pleasant salty/sweet flavor. You could use unsalted butter if you prefer.
- Chocolate Chips: Purchase a good quality semi-sweet chocolate chip for the chocolate layer of these delicious bars!
- Peanut Butter Chips: This puts the “swirl” in peanut butter swirl! This is for all my true peanut butter lovers out there!
What Tools Do I Need to Make Peanut Butter Swirl Bars:
- Parchment Paper: This is an absolute must! I used to try to save money by avoiding parchment paper, but it is SO WORTH IT! Prevent sticking and make for easy slicing by using parchment paper! My trick? Crumple it up before you fit it to the sides of the pan: it stays in place so much better!
- Silicone Spatula: Melting chocolate can be tricky work, and a lot of the chocolate sticks to the side of the bowl. A good silicone spatula will help you get every last bit. You can buy a set of 3 for less than $10 if you don’t have one on hand.
- Double Boiler: You can use a bowl set over a pot of water, but a real double boiler is probably going to be a lot easier and a lot safer (hello steam!). This one is under $20!
