Chocolate, peanut butter, Rice Krispies and marshmallows make these easy rocky road bars impossible to resist. They’re kind of like a homemade chocolate bar, or a chocolate Rice Krispie treat. The cereal makes them a little crunchy, the marshmallows make them a little chewy, and the chocolate and peanut butter make them just a little gooey.
Plus – there’s only 5 ingredients and they’re completely no bake. So it’s also a super easy recipe.
How to Make No-Bake Rocky Road Bars
This recipe is super easy to make. Here’s what’s involved.
- Place ¼ butter, ¾ peanut butter, and 2 cups chocolate chips in a large microwave-safe bowl.
- Melt in the microwave. Microwave for 1 minute intervals on medium power (not high or regular power), stirring in between each.
- Allow to cool slightly (this is so you don’t melt the marshmallows).
- Then stir in 1 ½ cups Rice Krispies and 3 cups mini marshmallows.
- Pour the mixture into a lined pan, and chill in the fridge.
Seriously, the whole thing comes together in no time. You can also add in some chopped peanuts if you prefer, and you can always use crunchy peanut butter or smooth.
Pro Tip: Line the pan with parchment paper or aluminum and make sure to leave an overhang around the edges of the pan. This way, after the bars have set you can easily lift them out of the pan and cut into bars.
Either way, these no bake rocky road squares are such a delicious treat that take almost no time to make.
I like making these over Christmas time because I can easily make a batch while other things are cooking in the oven. Plus, since it only uses one bowl – there are way less dishes.
So if you love peanut butter and chocolate – these no-bake rocky road squares are definitely for you.
