Peanut Butter and Chocolate is a timeless flavor combo that everyone loves. Whether you love some classic Reese’s Peanut Butter Cups, or perhaps like to get a little more decadent with these Peanut Butter Buckeye Brownie Cups, the combination of salty peanut butter with sweet chocolate is heavenly!
These Crunchy Peanut Butter Marshmallow Bars are no exception to that rule. A soft layer of chocolate cake is topped with toasted marshmallows and a crunchy mixture of crispy rice cereal, peanuts, peanut butter and peanut butter chips for a flavorful treat that is sure to be a household favorite!

Peanut Butter Bars
The sweet and salty flavor combo is to die for in this dessert recipe. It may appear to be more of a complicated recipe with the three layers, but that couldn’t be further from the truth. It starts out with a layer made from a simple box of cake mix combined with butter and egg, topped with a bag of mini marshmallows.
The top layer comes together in just a matter of minutes on the stove top and is layered over the marshmallows. Allow the Crunchy Peanut Butter Marshmallow Bars to chill for an hour and they are ready to be devoured. I assure you, they won’t last long!
My personal favorite when it comes to flavored peanut butter is Peanut Butter & Co’s Dark Chocolate Dreams Peanut Butter. From this Dark Chocolate Dream Cake to this easy 2 ingredient Healthy Peanut Butter & Chocolate “Ice Cream”, it brings the ultimate peanut butter and chocolate combo to any recipe! Not only is it great in recipes, but I could happily eat it by the spoonful as well.
