I searched high and low for this recipe; internet, cookbooks…FINALLY my GREAT GREAT grandmother pulled out an extremely old cook book of hers, all wrapped up in a plastic bag so the pages wouldn’t get any further damage, and told me she vaguely remembers making a fudge icing recipe from this book with her kids when they were little…WOW! Just one look at it I knew it was exactly what I had been searching for! This is a REAL FUDGE icing…its made just the way you would cook a regular fudge! The only alteration I added was stirring in a little heavy whipping cream at the end, to keep it spreadable because this icing does set very quickly as it cools. I have not had much ease using it as an icing to cover the cake, but its a very yummy filling for cakes and cupcakes. You can pour it like a ganache while it is still hot, but if you want a smooth finish don’t touch it!! It sets with in seconds after going on the cake. This icing is very thick and stable, no need to dam your cakes, its not going anywhere!!


  • 1 5oz. can of PET Milk
  • 1/2 cup real butter (one stick)
  • 2 cups of white granulated sugar
  • 12 large marshmallows
  • 6 oz. semi-sweet chocolate chips
  • 1 teaspoon vanilla
  • *OPTIONAL ADD INS* I will elaborate on the add ins later…

  • 1/4 cup+ heavy whipping cream
  • 1/4 cup peanut butter
  • 1/4 cup Nutella, chocolate hazelnut spread


  1. Combine in a stainless or glass bowl the marshmallows and chocolate. Set aside.
    Combine Pet milk, butter, and sugar in medium saucepan. Bring to a boil over medium high heat. Once it begins to boil, stir constantly, but slowly, for 5 minutes. Pour immediately over the chocolate and marshmellows. Add vanilla. Wait about 1 minute and begin to combine with whisk, being sure to melt and combine all the marhsmellows and chocolate.
    At this point you may add any of the optional extras. I usually will add the whipping cream just to make it easier to spread. Enjoy!
    This makes enough to fill 3 8in double layer cakes!

I tried the recipe this week and it did not thicken after beating it. Decided to leave it in the fridge overnight and still looks liquid like. Something I may have missed?

Yummy...if you like fudge you'll like this filling. Tastes just like fudge just not as dense. I didn't have any trouble with it not setting up, once it cools its pretty thick. Kind of a peanut butter consistency..maybe a bit thicker. I couldn't keep my kids out of the bowl.

Icgsweetemptations, did you cook it?? It is usually so thick I HAVE to add extra liquids and spread very quickly, try it again! It is worth it!!

tmelrose, this cake does go great with both vanilla and chocolate cakes! Imagine walking into a store that makes home made fudge the old fashioned way..this is very similar in taste! Just slightly thinner for spreading :) Hope ya'll like it!

What is the consistency and color? Is it like a ganoche or like an icing. I'm thinking of using this to top a big "hostess cupcake" cake but an worried of what it will look like.

This turned out GREAT! I did not need to add the whipping cream, as it was thin enough to frost, yet not too thick! Thanks!

Do you melt the chocolate chips & marshmallows before combining them or do they melt when you pour the milk mixture over it? Thanks!

AC7417 Says... 2011-10-26 15:48:24

Tammy96..they melt when you pour the milk mixture over it. I've made this about 3 times now with rave reviews. Love it!!

BEST. CHOCOLATE. FUDGE. RECIPE. EVER. Smooth, creamy, tastes just like fudge and i couldn't stop tasting it. I only added 1 2/3 cup of sugar since I ran out but it was absolutely fine. Thanks for the recipe :D
