This is absolutely the BEST Chocolate Frosting! Not to mention how EASY it is. Everyone who makes it loves how chocolatey it is, and it's made without butter or icing sugar! It's not messy to make and it isn't too sweet. This is perfectly balanced and I can't wait for you to try it! It is based on a classic ganache starting with chocolate and cream. This is the frosting that I pair with my BEST Moist Chocolate Cake recipe and it is like eating a chocolate truffle. I know you'll love it! Enjoy.

WHY THIS RECIPE WORKS
- EASY TO MAKE - this chocolate frosting is SO EASY to make all in one bowl and you don't need an electric mixer.
- Simple ingredients - you only need 5 simple ingredients that you likely have at home already.
- Fudgy dark chocolate frosting - it has the most fudgy texture that's literally like eating a chocolate truffle.
- Not too sweet - the best part about this chocolate frosting is that it is not-too-sweet thanks to sour cream that balances out the sweetness and no added sugar. Sugar only comes from the chocolate.
- No soft butter needed - you don't need to wait for your butter to soften to make this because there is no butter in it!

INGREDIENTS FOR THE BEST CHOCOLATE FROSTING
- Dark chocolate - you'll need pure dark chocolate to make this frosting. Anything between 50 and 70% cocoa solids will work, but I highly recommend dark chocolate with 60% cocoa solids. You can blend this semisweet chocolate with my favorite bittersweet chocolate callets which are very convenient.
- Cream - you need heavy cream or whipping cream with 35% milk fat.
- Honey - any type of liquid honey will work. It will keep the frosting fudgy and also gives it a beautiful shine. If you don't prefer the taste of honey, you can also use corn syrup.
- Cocoa powder - any kind will work. I love to use this Dutch Process cocoa powder. Make sure you use unsweetened cocoa powder and not cocoa mix.
- Sour cream - full fat sour cream adds tanginess to balance the sweetness and also creates a luscious texture.

STEP BY STEP INSTRUCTIONS
- STEP 1). Make a ganache. Combine cream and honey in a saucepan over medium heat and bring it to a boil. Stir once in a while to ensure the cream doesn't scorch on the bottom of the pan. Pour it over the chopped chocolate in a large bowl and stir until completely melted, smooth and glossy.
- STEP 2). Mix in sour cream. Whisk in cocoa powder. Add sour cream and whisk it through so it is evenly combined.
- STEP 3). Cool. Let cool for 15 minutes then beat with a whisk until thick and lightened a bit. If your kitchen is warm, place it in the fridge for a few minutes to help it set faster.
- STEP 4). Frost the cake! Spread over cooled cake layers immediately as it will thicken to a fudge consistency as it cools. You must pair this frosting with my BEST Moist Chocolate Cake! It is the most popular recipe on this website and everyone who makes it raves about it!

EXPERT BAKING TIPS FOR THE BEST CHOCOLATE FROSTING
- Use semisweet dark chocolate between 50% and 55% cocoa solids for best results. Do not use milk chocolate for this recipe - it will not work. Bittersweet chocolate with a higher cocoa content will make a stiffer frosting with a more bitter taste. See notes down below in the FAQ section to learn how to adapt the recipe to accommodate darker chocolate.
- Chop the chocolate finely - when making ganache, it is important that all of the chocolate melts gently and evenly. The smaller the pieces, the more evenly it will melt and it result in a smooth, homogeneous emulsion. If you are using these particular semisweet couverture dark chocolate chips, then there's no need to chop them.
- Do not over mix- do not over-mix the frosting at the last step after it has cooled. You want to whisk just until it turns a slightly lighter color. If you over-whip, then it will stiffen up immediately and become difficult to spread.
- Keep an eye on the cooling time. If it is hot where you are and you choose to cool the frosting in the fridge, then be sure to check on it every 5 minutes and give it a stir. If left unattended it will set to a firm consistency and be impossible to whip.

RECIPE FAQ
Although I mostly use 70% bittersweet chocolate for baking, this frosting recipe is ideal with dark chocolate between 50 and 55% cocoa solids. This frosting has no additional sugar other than the small amount of honey so it relies on the sugar in chocolate for sweetness. Also, using darker chocolate will introduce more cocoa solids which will throw off the cocoa:liquid balance to affect the final consistency. I prefer this dark chocolate.
If you prefer a more intense chocolate taste, you can make this recipe using 3 oz of 70% bittersweet chocolate and 5 oz of semisweet chocolate to make up the total of 8 oz. In this case, follow the "adapted version" of the recipe down below with 1 cup of cream, then reduce the cocoa powder to 2 tablespoons instead of 3.
If sour cream is not available to you where you live, you can also make this recipe using an equal amount of full fat Greek yogurt. I have tested this and it worked well! Another suitable substitution is crème fraîche -- a type of fermented dairy product somewhere between yogurt and sour cream.
If you can't get a hold of honey, you can replace it with corn syrup or agave syrup. I would not recommend maple syrup since maple syrup contains almost twice as much moisture as honey and it will affect the consistency of the frosting. Honey helps to keep the consistency silky, extra cocoa powder helps to boost the chocolate flavor intensity and sour cream adds a tanginess that complements the sweet and bitter flavors to make for one complex and totally delicious frosting.
Honey is mostly functional in this recipe. In addition to adding slight tanginess and subtle floral notes for a more complex flavor profile, it also a hygroscopic ingredient which means that it binds moisture and creates a glossy finish.
If you have over-whipped or over-chilled the frosting and it stiffens up, you can try to save it by microwaving it for 15-20 seconds until soft and glossy again, then add 1 teaspoon of cold cream and stir gently with a whisk to blend evenly. Let the frosting cool gently at room temperature until thick and use immediately.

The BEST Chocolate Frosting
Ingredients
Original Recipe:
- 8 oz (227g) semisweet dark chocolate* (I love these couverture chocolate chips)
- ¾ cup (180ml) heavy 35% whipping cream
- 2 tablespoon (30ml) honey or corn syrup
- 2 tablespoon (12g) (cocoa powder (I prefer this one)
- ⅓ cup (80ml) full fat sour cream
Adapted version for slightly larger batch with softer texture:
- 8 oz (227g) semisweet dark chocolate* (I love these couverture chocolate chips)
- 1 cup (237ml) heavy 35% whipping cream
- 2 ½ tablespoon (37ml) honey or corn syrup
- 3 tablespoon (18g) (cocoa powder (I prefer this one)
- ⅓ cup (80ml) full fat sour cream
*It is important to use semisweet chocolate with 50-55% cocoa solids. If you use anything darker, the frosting will not be sweet enough and the consistency will be firmer. These semisweet dark chocolate chips have a high cocoa butter content and will make the best frosting. See tips above in FAQ section for how to make this frosting with other types of chocolate.

Instructions
- Finely chop the chocolate and place it in a heatproof bowl. If you are using these couverture chocolate chips then there's no need to chop them.
- Combine whipping cream and honey or corn syrup in a small 1 quart saucepan over low heat and bring it to a gentle boil. Once it reaches a boil, immediately remove it from the heat and pour it over the chopped chocolate. Cover the bowl and let stand for 2 minutes. Remove the cover and stir in concentric circles using a spatula or a whisk until smooth and glossy.
- Add sour cream, sift in cocoa powder and whisk it through gently. Do not whisk vigorously because incorporating air at this stage will cause the ganache to split.
- Place the bowl in the fridge for about 10 minutes, then stir gently. Let chill for another 10 minutes or so until thickened. Do not leave it in much longer or it will set up firm. If it is still really runny, then place it back in the fridge for another 5 minutes.
- Once it is thick like the consistency of pudding, whisk vigorously for about 15 seconds by hand using a wire whisk until thick and lightened in color just a bit. Stop whisking if it starts to look matte and thick - just whip a few times to incorporate some air but it should still stay glossy. You'll notice it will start to thicken as it sits as the chocolate sets around the fine air bubbles. Use the frosting immediately. It will continue to firm up as you spread it.
- Use an offset spatula to spread the frosting over the cooled cake layers right away and avoid spreading around too much as the back and forth motion will cause the cocoa butter to crystallize and make the frosting stiffen up. *NOTE: This recipe makes just enough to cover a 2 layer 8-inch round cake with a thin layer to cover the sides because it is very rich. If you prefer a thicker layer of frosting, simple double the quantities of all ingredients and then it will take longer for the mixture to cool until thickened since there is a larger volume.

I love this frosting so much. It isn’t too sweet and not too rich yet decadent at the same time. It swirls like a dream too!

Hi, nope not at all!

Hi. Can I use non-dairy whipping cream? Thanks

Hi Jac, I haven't tested that but I wouldn't recommend it. It may not set the same way.

Hi can I put this frosting and keep the cake at room temperature for 2-3 days since it has sour cream a little concerned
christina.marsigliese
Hi, if your climate is cool then yes, it should be fine for 2-3 days.
Jayne
PERFECTION!!! No sugary, gritty frosting. This is the BOMB!!! So worthy of my chocolate cake. Thank you, it's the only frosting I will ever use.
christina.marsigliese
Hi Jayne! Yeah! I'm so glad to hear! I don't like sugary frostings either!

Enjoy!
Sara
Thank you for the recipe, I couldn’t manage to find whipping cream, can i use a mix of both single (18%) and double(48%) cream instead? Xx
christina.marsigliese
Yes you could! Just make sure you blend in a way that the average milkfat content is 35%.
christina.marsigliese
Hi Sara, yes you can. Just blend them in a way that the final milkfat % is 35.
Ayush
Hey Christina ! We don't get sour cream easily in India, so is there anything sour cream be replaced with ?
christina.marsigliese
Hi Ayush! You can use thick full fat yogurt.

Sorry if these questions seem silly, I'm a baking novice. I noticed some of the comments specifically said you need 60% cocoa for this recipe to work. What if I had 100% cocoa powder? Can I still use that? Would I need a different quantity? Also what is 35% whipping cream? I have heavy whipping cream but not sure if that's the same?
christina.marsigliese
Hi, this recipe requires chocolate, not cocoa powder. Heavy whipping cream is the same as 35% whipping cream 🙂
Nargess
Hi.. The ingredients say 2 tbsp 12g Cocoa powder, right?
Thank you ?
Stephanie G
Hello, this cake can stay out? No refrigeration? Just making sure!
christina.marsigliese
For a couple of days it can if your climate is cool.
Dina
I had a page “bookmarked”, Scientifically Sweet - The Best Dark Chocolate Fudge Frosting”. When I “click” to go there it takes me to a not recipe related page now. The last time I made this frosting wasn’t too long ago. The frosting was made with “water”. No honey or sour cream. It looks like the frosting in the photos. I loved this frosting made with water. Was it your recipe? Where can I find it again? if it was yours.
christina.marsigliese
Hi Dina, hmmm I'm not sure but the Devil's Food Cake in my first cookbook "Scientifically Sweet" has a chocolate water ganache frosting.
Dinq
Thank You for the reply!!
Phyllis
Wow cuz this is great work! Congrats and keep it up!
monika
I am making this frosting right now...but it is NOT setting up. It's too loose...and this after letting it sit for 50 minutes. Does it need to be refrigerated before beating?
christina.marsigliese
Hi! You can put it in the fridge to help it set up faster. If your chocolate was too low in cocoa content then it might not set properly.
Anonymous
The problem was your indication of "wait ten minutes". My cocoa was not too low - it was semi-sweet (over 60% cocoa). It took about 50 minutes at room temperature to get to a consistency that was spreadable....Maybe ten minutes in the FRIDGE...
christina.marsigliese
Hi again, semi-sweet chocolate has 50% or less of cocoa. So next time use a better quality chocolate. Glad it worked out for you in the end!
monika
Will regular baker's chocolate work?
christina.marsigliese
Hi Monika, as long as the cocoa content is around 60% then it will work.
