These rocky road bars are the EASIEST to make but are full of so many delicious flavors and textures. A fudgy peanut butter chocolate is filled with marshmallows, salted pretzels, candy coated chocolates, and a layer of peanut butter cups. This recipe is also VERY easy to customize so feel free to load these up with your favorite mix-ins!
How to Make Rocky Road Bars
These bars start with a chocolate base that’s incredibly rich, creamy, and fudgy.
Chocolate, coconut oil, and peanut butter are all melted down and mixed together to create a glue that holds together all of the essential mix-ins:
Marshmallows are traditional to rocky road, but the addition of crunchy salted pretzels adds the perfect layer of salty-sweet goodness. I also love the light snap of the M&M candy coated shell as well as the sweet milk chocolate flavor.
But to take these over-the-top, a layer of peanut butter cups in nestled in the very center of these bars. Each bite is met with a big chunk of peanut butter along with fluffy marshmallows, crunchy pretzels, and snappy M&M’s – all blanketed in smooth and fudgy chocolate.
These bars may be incredibly easy to make, but they are most definitely not lacking in flavor!
Peanut Butter Rocky Road Mix-Ins
The best part about this recipe is that it can be easily customized to whatever you have in your pantry. Especially after the Holidays, there’s always a ton of leftover bits and pieces from cookie baking and decorating so this is the perfect place to use those up.
To stay true to the rocky road flavor, I suggest sticking with the marshmallows. The pretzels also help balance out the sweetness so keep those in as well.
As far as everything else, the amounts of the marshmallows and pretzels can be adjusted to accommodate anything else you’d like to add. As long as they all add up to a total of 3 heaping cups plus 1/2 cup.
Mix-ins I think would work great in this recipe include:
- Roasted nuts
- Broken up crispy cookies
- Dried cranberries
- Toffee Bits
