Semisweet Chip Rocky Road Frosting

Total Time
Prep 5 mins
Cook 15 mins

I do not typically have milk chocolate chips so this is the Rocky Road version I use. I put this onto Sue B's Chocolate Cake. The recipe is from Chocolate from the Cake Mix Doctor. I have only used this for flat surfaces and not the sides of a cake.

Ingredients Nutrition


  1. Place the sugar, butter, and milk in a small saucepan over medium-low heat and cook, stirring constantly, until the mixture comes to a boil, 3 to 4 minutes.
  2. Boil, stirring constantly, for 2 minutes.
  3. Remove the pan from the heat, add the chocolate chips, and stir until they are melted.
  4. Let the pan rest off the heat to cool slightly but not completely, 3 to 4 minutes.
  5. Fold in the peanuts and marshmallows until they are well combined and the heat from the frosting begins to melt the marshmallows.
  6. Turn the frosting out onto the cooled cake, then spread evenly with a spatula until the frosting covers the entire cake.
  7. Or spread onto cooled cupcakes.

This is a fabulously easy recipe. I have made it before as directed, but this time I wanted to change it up a bit. So I substituted some toasted walnuts for the peanuts, and instead of mixing them in, I sprinkled them on top. Voila, a Mississippi Mud Cake when put on top of Dark Chocolate Sheet Cake. Rich and sweet and satisfying! Thanks for posting The Doctor's great recipe.

I needed a chocolate icing recipe for cupcakes at the last minute, using things I had in the cupboard. This one worked pretty well. I added the marshmallows, but didn't like the lumpy texture so I let them melt in all the way, and ended up with a nice, smooth chocolate glaze. I left out the nuts since I didn't have any. I was able to ice about 30 cupcakes (I was in a hurry and didn't let it cool, so it spread thin, which I didn't mind). I have about 3/4 cup left in the fridge which, after I heat it up a bit, should make a nice, thick frosting for brownies. Thanks for the recipe!

I followed this recipe to the T since I had never done a rocky road icing before. When I went to put it on the cake the frosting did not stick well to the sides of it. It just kind of clumped onto some parts. Not sure how to remedy this from happening in the future
