Fudge Icing Recipe

March 15, 2026 By Gretchen

Jump to Recipe Print Recipe

It’s the same recipe I used when I had my bakery!

Pro Bakery Fudge Icing Recipe is now yours to make with ease at home!
Only now it’s got half the sugar!
Believe it or not the original  recipe used to be eight whole cups of confectioners sugar!
Perhaps I was much sweeter in my younger years! LOL

Vegan Fudge Icing Recipe

 

 

Notes for Success:

Corn syrup is a “no” for many people so feel free to use Agave, Maple Syrup or Golden Syrup instead
Even molasses would give this fudge icing a nice twist!

The original recipe and video listed coconut oil in the ingredients
But after many people had white streaks or a film of white oil and sometimes separation 
I have traced this back to the coconut oil and now use all vegan butter in it’s place

PRO TIP:

Just by adding about a cup of this fudge icing to your favorite buttercream recipe you get instant chocolate buttercream!

    How well does it freeze?

    • Gretchen

      October 31, 2018 at 3:48 am

      Fine, just thaw it in the refrigerator overnight then let it get to room temperature for an hour or so before rewhipping, you may need to add another tbs or two of warm water to get it smooth and creamy

    Hello!
    Is it ok to use agave instead of corn syrup in this recipe?

    • Gretchen

      April 10, 2019 at 2:25 pm

      yes!

    Hey Gretchen, so proud to find out you became a vegan and also very relieved, because I could never find a vegan version of brownies as good as your non vegan brownie XD Literally EVERYONE that has eaten your non vegan brownie here in Brazil was stunned!

    I’m wondering, how many cupcakes or brownie pieces do 6 cups of icing cover? I’m planning to sell these here in Brazil! <3 Thank you for the wonderful recipes.

    • Gretchen

      January 10, 2020 at 6:50 pm

      Hi Great thanks! Well it depends on how much you want to ice them! 😀
      This recipe makes 6 cups- so you will have to estimate how much you will put on each one, then do a little division to get an accurate yield

    Hello Gretchen! Is this recipe similar to the fudge that you had years ago? I made that one and loved it. I’m making a cake and I want to use it as a filling

    • Gretchen

      July 3, 2020 at 5:55 pm

      YES! it is exactly the same recipe!

    Hi Gretchen – a while ago I think I remember you talked about using chocolate chips in frosting. Can you say again what the problems might be? thanks

    • Gretchen

      July 20, 2020 at 4:24 pm

      Chocolate chips are not meant to melt. They have added ingredients in them to keep them from melting away in (specifically) cookies which is what they were designed to do.
      So, especially on the lower grade brands they have waxes and such.
      It would probably be OK here, but again a more expensive chip will be the same as buying some real deal couverture. I get Baker’s Brand Chocolate bars (4oz bars for like $2.50) in my local ShopRite (and walmart has it too)

        thanks Gretchen – really appreciate all you do

    What else can we use apart from corn syrup? You mention agave but could you use for example xylitol? What liquid would you mix it with & what quantities? What else might we be able to use? Thank you

    • Gretchen

      September 17, 2020 at 2:34 pm

      Hi Cathy, I have not personally used xylitol, but I am pretty sure it would work as a replacement for the cornsyrup here. I’d just add a bit more liquid (water) at the end as I show in the video to adjust the consistency.

      But if you are trying to make this a low sugar recipe, I wouldn’t recommend that. There is such a large amount of confectioners sugar here, that even replacing JUST the cornsyrup part, what is that really going to do? Not much in the grand scheme of things.
      For a lower sugar, WAY HEALTHIER version of a chocolate icing, you can use ganache instead. It’s easy, 2 ingredients- low sugar in comparison to this recipe. CLICK HERE

    Hi Gretchen!
    I wonder if this recipe is enough to frost an 8inch cake without to much leftovers. im making a birthday cake and wanted to have as little leftover frosting as i can, I always make to much.

    • Gretchen

      October 29, 2020 at 2:29 pm

      If you are just frosting and NOT filling? It’s going to be extra, but you could HALF the recipe OR freeze excess 🙂

    Is there any type of vegan butter you recommend. I was looking in the store and saw Becel for 2.50 and then earth balance for 5.50. Would it matter in this recipe?

    • Gretchen

      May 7, 2021 at 2:41 am

      It wouldn’t matter here, the only time I am sure to use Earth Balance with no subs in in a buttercream recipe- Earth Balance is the lowest moisture and will get hard in the fridge, no other one will do that (that I know of)

    Hello Gretchen, your recipes are simply amazing! You have so much talent in you, and i am so glad you decided to share it with the world. I made your peanut butter fudge brittle cake a few days age, and , i was simply shocked. It was so good!! I made it for my dad for fathers day because he loves peanut butter so much, and he was so happy! thank you so much! I do have a question though. I love your fudge icing and i make it a lot, it is so rich and chocolaty and i make it at least once every week, but every single time i make it, if i put it into a piping bag and start piping, or if i leave it in the mixer bowl, it get white streaks in it. and not pretty streaks. every time i pipe with it, the first few look great, but then the white appears and i don’t know what to do. I follow the recipe exactly! Do you know what’s wrong? If you do, please tell me. Thank you!!!

    • Gretchen

      June 22, 2021 at 11:59 pm

      Hey great thanks!!! That has happened to me before too, and I think it is from the shortening addition? Because I now use all vegan butter (earth balance specifically – lowest moisture) and this has not happened

  13. Suhaani

    July 2, 2021 at 1:49 pm

    hey. What can i substitute for vegetable shortening?
    Love your channel and website. I am a vegetarian (will soon turn vegan) and i am excited to make these for my non-vegetarian family and friends

    • Gretchen

      July 2, 2021 at 3:16 pm

      Great! More vegan butter in same quantity as listed

  14. dan

    September 26, 2021 at 3:06 am

    I read above that I can substitute more vegan butter for the veg shortening.

    Why does the recipe call for shortening? Is it to firm up the icing?

    Thanks

    • Gretchen

      September 26, 2021 at 1:11 pm

      Yes to both, Shortening is only ever used as a stabilizer for icings, lots of people like to stay away from using it, so you can use all vegan butter in it’s place. I do it all the time, the amount here is so little that it really doesn’t change anything at all. This was a recipe I converted from my bakery that was GIANT! So when I scaled it down, the shortening that started out at like 2lb for the entire recipe, ended up being so small, so I probably just should have omitted it from the start

    Hello, Gretchen

    Pretty sure I’ve lost weight from all the salivating I’m doing just looking at your amazing desserts!

    I have a question I’m hoping you can help with:

    It was recently pointed out to me that a lot of sugar is filtered with bone char. Obviously, if it’s certified organic, or certified vegan, that wouldn’t be the case.

    Do your recipes factor that in?

    Thank you for taking the time to read, and hopefully, answer. Thank you also for these tremendous ideas and inspirations!
    ????
    Tim

    • Gretchen

      November 3, 2021 at 1:40 am

      Hi Tim thanks! And you are welcome too! 🙂
      Yes that is correct most sugar (in the US) is processed through animal bone char. I use Zulka brand sugar in all my recipes, so yes~ I guess you can say I factor that in
      For the powdered sugar you can make your own, since the store bought ones are super expensive!

    Not sure what went wrong here. I followed the instructions to a T. I made two batches, one the way you make it in the video and one the way the recipe is written. They both refused to come together, it looks curdled and oily and there is a white milky substance that accumulates on the surface. I guess I will need to try another recipe in the morning. Such a shame. Any idea what could have gone wrong?

    • Gretchen

      July 16, 2022 at 4:30 pm

      Oh no! Sounds like an emulsion problem (*oversaturation of fats: other ingredients) that is the #1 reason recipes like this & buttercream “break” aka Curdle.
      I would suggest to warm up some of it (just like a 1/2 cup, not to the point it is melted, but then add it back to the main bowl and mix
      Sometimes I take a blow torch to the sides of the bowl as it is mixing which is effectively the same thing.

    Hi Gretchen, I just made this mouth watering icing, but the emulsion broke 🙁 What is the best way to get the right consistency back? Thank you for the recipes, they are amazing!

    • Gretchen

      March 1, 2023 at 7:20 pm

      Oh No! Some others have had that problem, and I can only suspect it is the vegan butter being used? If the vegan butter has too much moisture content it can cause over saturation & thus breaking (curdling) You can add some more confectioners sugar to help absorb some of that excess moisture to regain a proper balance

      • Véronique

        March 1, 2023 at 8:29 pm

        I tried something before I saw your answer; I put the icing in my food processor, it worked as far as the emulsion goes, but it’s more liquid, I will try add some more confectioners sugar. Thank you for your help! It is so delicious, I could eat it with a spoon, which I did…

    Hi Gretchen!
    I am excited to try this recipe. I am thinking that I will split it, and add peppermint extract to half and use it as a cupcake filling…. Thoughts? Maybe 1Tsp?
    Then, I will top the cupcake with chocolate frosting and a homemade peppermint patty. Or, maybe vanilla frosting and a sprinkle of crushed peppermint…..Im not much of a chocolate fan, but my family is! Id love to hear your suggestions!
    With the holidays approaching, I love getting things made ahead of time
    Thanks again for all of your amazing recipes!!

    • Gretchen

      November 14, 2023 at 7:26 pm

      Yes great! In my experience various brands of extracts will vary so I always start with a lot less than I think I need to avoid “toothpaste” flavored icing! 🙂
      So yes I 1tsp per half sounds like a good starting place!
      I am a double & triple chocolate person so for me that sounds fab! Although I also really love the vanilla crushed mint version too
      So since I can;t decide I think you have to make both LOL

    This tastes amazing!! I ran out of cocoa powder, so I had to sub with like 30g of espresso powder and it still tasted delicious.

    Hi Gretchen! I just made your fudge icing and followed exact steps and used earth balance vegan butter sticks ! I noticed that it was a little too loose/runny for my piping cupcakes so I added two more cups of sifted confectioners sugar. It took care of it but then as soon as I put it in the icing bag it started turning white !! I fixed the problem by sprinkling jt with crumbled peppermint pattie cookies. Overall my husband and I LOVED the taste! Thanks for this vegan recipe but I wonder why it stated turning white in the piping bag ??

    • Gretchen

      October 6, 2024 at 11:25 pm

      Hey thanks for the comment, some other people have had similar trouble with this recipe, so I decided to eliminate the coconut oil addition (from the original recipe) and replaced with all vegan butter as the recipe now reflects.
      I have however reduced the sugar severely from the original bakery recipe so this could be posing the problem, but I will maintain that I always use this new amount of sugar (compared to 8 cups!!) and have no trouble ~ Perhaps it is over saturated with fats compared to sugar, which explains why when you added more sugar is helped/ I’ll have to look into this more- sounds like a recipe of fudge icing is in my near future~ Yumm (but I have to wait for this hurricane to do it’s thang!) Ugggh

      • Susie

        October 8, 2024 at 9:57 pm

        Yes I’ll be waiting for another fudge icing recipe. I hope you’re well and safe out there !
