Rocky Road Brownies

Traditional Rocky Road ice cream is one of my favorites.  I love to pair it with a fresh from the oven brownie, so this combination just makes perfect sense!  Rocky Road ice cream was invented during the great depression when the most common flavors were vanilla and chocolate. The folks that made it named it “rocky road” to give people something to smile about in the face of some pretty uncertain times.  It’s amazing to me that ice cream of any kind could have such an impact.  It probably helps that Chocolate Ice Cream with nuts and chocolate chunks and marshmallows pair pretty nicely together.

  1. I have made this recipe from a cookbook. The only difference was using your own preference of nuts. Also, I suggest letting these cool completely and then with wet knife, slice into squares. They are very good.

  2. I LOVE YOUR RECIPES!!!

    I have shared them with many of my friends & family…they always ask for the recipe & I have shared your website many times!
    Thanks again, Mary Roshto
    Thank you for sharing!

  3. Use Baking powder or soda? In the ingredients and instructions it says powder but earlier in the post it says baking soda. Hoping it’s baking powder because they are in the oven!
