This bar is a favorite childhood memory. My mom would occasionally make these when we had company. They were always my favorite treat. I remember sneaking them from the fridge... so that's where that bad habit came from! Shame on me, lol! They are like eating fudge but more airy because the marshmallows don't melt.

Blue Ribbon Recipe

Super simple to make, these no-bake chocolate marshmallow bars are full of flavor and textures. They remind us of Rocky Road ice cream in a fudgy candy form. Chocolate and marshmallows pair perfectly. The chocolate is rich and has a slight peanut butter flavor. Coconut adds even more flavor and texture. We didn't add the optional walnuts and regretted that after we took a bite. We suggest adding them to make these no-bake bars even better.
