My chocolate fudge frosting is simple to make and tastes better than any store-bought or canned frosting! It’s thick and rich and dries firm with an oh-so-fudgy consistency. No candy thermometer or special equipment needed! Recipe includes a how-to video!
A Chocolate Lover’s Perfect Frosting
I gave you a sneak peek at this frosting earlier this week. It’s that deep, dark, thick, and fudgy chocolate fudge frosting I teased over my insanely decadent devil’s food cake.
This is the perfect frosting to take a dessert to the next level of decadence, and it joins the ranks of some of my favorite frosting recipes. Not too sweet, there’s no candy thermometer needed, it sets up fudgy and firm, and it’s quite simple to make (though you do need some patience!).
Let’s get to it!
Fudge Frosting Ingredients
Fudge frosting requires only 6 basic ingredients. Here’s what you need:
- Chocolate. I highly recommend using an unsweetened chocolate bar (100% cacao) for this recipe. In a pinch, a dark chocolate (60% cacao or higher) could be used, but the lower your percentage the sweeter your frosting will be. I found that using an unsweetened chocolate gives you the best flavor and keeps the icing from being too sweet.
- Milk. I recommend whole milk for this recipe, it helps the frosting to set properly and lends itself to the rich, creamy consistency.
- Salt. A pinch of salt balances the sweetness from the sugar. I found ¼ teaspoon was not quite enough while ½ teaspoon was too much, so I recommend using ¼ teaspoon but over-filling it.
- Butter. A little butter goes a long way. It helps create the glossy shine of the chocolate fudge frosting and adds to the full-bodied fudgy mouthfeel. Use unsalted and add a pinch of salt for maximum control over the flavor. However, if you only have salted butter simply leave out the salt in the recipe.
- Powdered sugar. This makes the frosting sweet and smooth without making it grainy. The sugar is also critical to help the frosting set up properly.
- Vanilla extract. Chocolate is always enhanced by a splash of vanilla, so we use it here for best flavor.
This is just an overview of the ingredients I used and why. For the full recipe please scroll down to the bottom of the post!
Making The Frosting
While today’s recipe has a truly fudgy taste and consistency, it’s much simpler to make than my chocolate fudge, and there’s no candy thermometer needed!
- Chop (or break) chocolate into small pieces that are similar in size (this helps it to melt evenly and reduces the chance of the chocolate seizing), and place in a saucepan (alternatively you could use a double boiler!).
- Add milk, butter, and salt and stir until the ingredients are melted together and smooth.
- Remove from heat and add powdered sugar and vanilla extract. In the video and photos above, I added the sugar directly to the saucepan, but if you don’t mind dirtying another dish I recommend pouring the chocolate into a separate heatproof bowl and then adding the sugar. The frosting will cool faster this way.
- Allow the frosting to cool until it is thickened to a consistency that is easy to spread or pipe (depending on what you’re doing with it!). Stir occasionally, otherwise the surface can begin to crust over.
SAM’S TIP: When making this frosting, it can be tempting to turn up the heat to encourage the chocolate and butter to quickly melt. Don’t do it! Heat that’s too high will cause your chocolate to seize and turn grainy and you’ll have to start over.
Fudge Frosting Consistency
- Chocolate fudge frosting is ready when it is cooled and the consistency is thick enough to spread or pipe onto cake or cupcakes. This waiting part takes time and patience and is the most annoying part of the whole process, but it’s very worth it!
- Pipe or spread the frosting onto your favorite cake or cupcakes (I’m piping it on my vanilla cupcakes in the image above). If it seems to be drooping or falling off the baked good, just give it a bit more time to cool.
Frequently Asked Questions
Most likely you just need to have a bit more patience and let it cool a bit longer! This frosting can take time to set up properly and exactly how long it takes depends on a number of factors including precisely how hot you heated it on the stovetop, how warm your kitchen is, and even how often you stir it as it cools (stirring it more often will help it cool faster).
If your frosting is grainy it is likely the heat was too high when you were melting your chocolate. High heat will “seize” the chocolate, causing it to be thick, lumpy and grainy (it can also cause the oils to separate from the chocolate!). Unfortunately, if this happens I recommend starting over (and keep the heat on low!).
Fudge frosting works with just about anything! Try it on marble cake, vanilla cake, or keep things rich and decadent by serving on chocolate cake or chocolate cupcakes! How about making a chocolate-covered strawberry cake?

- Remove chocolate mixture from the heat and pour into a large bowl. Add powdered sugar and vanilla extract and whisk until icing is glossy and smooth.4 ½ cups (565 g) powdered sugar, 1 ½ teaspoons vanilla extract
- Allow the frosting to cool, stirring occasionally, until it is thick enough to spread or pipe over cake/cupcakes (how long this takes will vary greatly depending on many factors including how hot the chocolate mixture became, the temperature of your kitchen, etc.). The more you whisk the mixture the faster it will cool.
Notes
Making in Advance
I do not recommend making this frosting far in advance of making your cake or cupcakes as it will become quite firm as it cools. Once it is too cool to spread or pipe, it’s hard to return to that consistency (re-warming the frosting will yield mixed results and I don’t recommend it).Storing
Once applied to your cake or cupcakes this frosting will keep at room temperature for up to 4 days or refrigerated for at least a week. It also freezes well.Nutrition

This is the best fudge frosting I have ever tasted. Just made it for the second time today, and I could just eat the whole bowl. We will see if I get any comments at the Christmas Party tonight!
Sam
I’m so glad you enjoyed it so much, Linda! I hope everyone else loves it too! 🙂
Linda
Verdict is in! Everyone, especially brother, loved the brownies. My brother said it was the best he ever had. I am sharing the frosting recipe with my co-worker now !!
Emily @ Sugar Spun Run
We are so happy they were a hit, Linda! 🥰
JASON
This frosting turned out very nice and was perfect for the brownie cookies I made. Very versatile as well. I made a second batch to play around with the recipe and see what I could do with different consistencies. I added less sugar and dipped the face of the cookies in so it gave the cookie a nice shiny glazed like appearance and equally as tasty. I added a little more sugar and put it between graham crackers which turned out nice as well. Thank you for the recipe. It was delicious and I had some fun 🙂
Sam
I’m so glad you enjoyed it so much, Jason. 🙂
Erica B
Kind of a silly question, but will sprinkles adhere to this frosting as well as they do to freshly-piped buttercream? For over a week, my 3-year-old has been planning which sprinkles we’re going to use to decorate Daddy’s birthday cupcakes, so maximum sprinkle adhesion is a must. 😄
Sam
Hi Erica! If you add them right away it will work just fine, otherwise the frosting will crust just a little bit making adhesion difficult. 🙂
Erica B
Thank you for the response! I ended up making a slightly altered version of your favorite chocolate frosting, and your peanut butter frosting for good measure. We enjoyed both recipes, and they accommodated PLENTY of sprinkles. 😆 Thank you so much!
Sam
I’m so glad you enjoyed it! 🙂
Kari Dyer
ran out of butter, can I use margarine? this is to frost á small cake today.
Sam
Hi Kari! I haven’t personally tried it, but I think it could work. 🙂
Riv K.
This was so so good!
Emily @ Sugar Spun Run
We’re so happy you like it, Riv! Enjoy 🩷
Kathy Ferrier
AMAZING!! This recipe is a keeper! Delicious!
Sam
I’m so glad you enjoyed it so much, Kathy! 🙂
Cate
The frosting tasted good but set up too quickly to frost a 3-layer cake. It wouldn’t adhere to the sides at all, so I couldn’t even do a crumb coat. It was much like a chocolate icing or glaze on a donut.
Sam
I’m so sorry to hear this happened, Cate! I have never actually run into this issue, I actually end up having to wait a while for it to set up. Did you make any substitutions or any alterations to the recipe?
Senthil
For the frosting, can I use heavy cream instead of milk?
Emily @ Sugar Spun Run
It could be pretty stiff and rich, but we think it could work 🙂
Ann L Mobley
We served this to our 5 grandchildren who had never had Devils Food cake. The frosting was a unanimous hands down all time favorite. It’s delicious~ not too sweet, very chocolatey!
Sam
I’m so glad everyone enjoyed it so much, Ann! 🙂
Kachina
Only once I’ve been able to make this frosting properly. Either the chocolate seizes before getting to add the sugar, even with a double boiler method, or it cools to quickly and I can’t spread it. I think there is something about the adding milk and butter at the beginning that adds too much liquid and causes the seizing. There must be a better way.
Sam
That sounds so frustrating Kachina! Are you using any substitutes? If not my first guess would be that the heat is too high. If it helps, I do have a step-by-step video where you can see me make it on camera.
Kachina
Hi again. Yes Sam, I use a double boiler to maintain proper temperature to guard from getting to hot. I think I’ll go back to keeping the milk out of the recipe until I pour into a bowl, before adding sugar.
Bruce
Easy, delicious, and fudgy. Absolutely weigh the sugar, rather than using cups, because mine became too thick to spread even before I got all the sugar (measured with cups) mixed in. I was able to pat it on, to make a naked cake, but that wasn’t what I wanted. I’ll definitely use the scale in the future.
Sam
I’m so glad you were still able to enjoy it, Bruce! 🙂
