Why This Recipe Works
This frosting combines the luxurious chocolate flavor of ganache with the buttery richness of buttercream to create a frosting that's the best of both worlds.
I wanted to be sure that this frosting was decadent without feeling over the top, and believe me, it's just right. This chocolate frosting recipe has deep chocolate flavor thanks to both cocoa powder and melted chocolate without feeling too heavy or dense. I simply replaced some of the confectioners' sugar in a classic buttercream frosting with cocoa powder and some slightly cooled chocolate ganache to create this indulgent-yet-balanced chocolate frosting.
Ingredient Notes & Substitutions
Heavy Cream- To create the chocolate ganache, heavy cream will be blended with the chopped chocolate. Choose cream labeled "heavy cream" or "heavy whipping cream" - not merely "whipping cream" - for the right fat content.
Bittersweet Chocolate Baking Bar - A chocolate baking bar (found in the baking aisle at grocery stores) is ideal for creating a creamy chocolate ganache. Avoid using a chocolate candy bar (which contains sweeteners and other ingredients) or chocolate chips (which contain stabilizers), since they won't yield the proper ganache texture. You can substitute semisweet chocolate for a slightly sweeter ganache and frosting.
Unsalted Butter - Be sure the butter is room temperature so that it will be smooth when blended. As always, I prefer to use unsalted butter so that we can control the amount of salt added to the recipe.
Dutch Process Cocoa Powder - Cocoa powder works in conjunction with the ganache to flavor the chocolate frosting. If you prefer, it's okay to substitute natural unsweetened cocoa powder, though this will change the flavor.

Special Equipment
In addition to essential baking equipment (like a spatula), I recommend some special tools for making this recipe.
- Small saucepan, for warming heavy cream
- Stand mixer or electric hand mixer, for mixing frosting
Step-By-Step Recipe Instructions
Step 1: Heat cream just until it begins to simmer and pour into a bowl with the chopped chocolate. Stir until the chocolate is completely melted and the mixture is smooth and shiny. Set the ganache aside and allow it to cool to room temperature.
Step 2: Using a stand mixer with the paddle attachment or an electric hand mixer, beat butter, vanilla, and salt until smooth.
Step 3: Add sugar and cocoa powder slowly, mixing until well blended.
Step 4: Add ganache to the frosting and mix until the frosting is light and fluffy.

Recipe Tips
Be sure the chocolate is finely chopped, since it will melt more easily this way when the warm cream is added.
To avoid lumps in your frosting, be sure that all of the chocolate in the ganache is melted and smooth and that your butter is room temperature when mixed.
Be sure the ganache is cooled to room temperature (about 75º F) before adding to the buttercream frosting so the ganache doesn't melt the butter in the frosting.
Recipe FAQs
It really comes down to personal preference! Chocolate ganache is less sweet and deeply chocolatey, while buttercream is rich and creamy and helps to keep cakes nice and moist.
With this recipe we get the best of both worlds by combining the two!
Cocoa powder adds a deeper chocolate flavor to frosting compared to melted chocolate, but it can also create a frosting that's dry, so you'll need extra liquid (like milk) to compensate. This recipe uses both melted chocolate and cocoa powder for decadent chocolate flavor and a moist, creamy frosting.
Storage Instructions
Refrigerator: This frosting can be stored in an airtight container in the fridge for up to 4 days. If you plan to refrigerate the frosting before using to decorate a dessert, let the frosting come to room temperature and briefly re-whip it with a stand mixer or electric hand mixer so that it's soft and fluffy before using.
Cakes or other desserts that have been decorated with chocolate ganache buttercream can be stored on a covered cake plate or stand at room temperature for up to 2 days or in the fridge for up to 4 days.

Hello,
If I want to bake 1 x of the chocolate cake recipe (https://alwayseatdessert.com/chocolate-cake/), Will 1 x serving of this chocolate ganache suffice in frosting the top, around the cake and in between 2 layers of the cake?
Thanks!

Hi Sharon! Yes, I mentioned this is the recipe notes of the recipe card. Since the frosting is so rich, I find myself using a little bit less. So while I would typically use about 4 cups of frosting to frost a two-layer 9 inch cake, I use just 3 cups (one recipe) of this frosting to frost a two-layer 9 inch cake.

Hello, so glad to find this recipe but what seems alarming is that for the 2X recipe, it calls for 3 cups of butter or 6 sticks of butter. Usually I see 1 cup or 2 sticks of butter to 4 cups of confectioners’ sugar. Why so much butter?
Thank you!

Hi Wanda! Great question! My classic American buttercream frosting also uses a ratio of 1 cup of butter to 4 cups of confectioners' sugar as you mentioned. This recipe is not a classic American buttercream, however. The cocoa powder in the recipe serves the same purpose as confectioners' sugar while also adding chocolate flavor, so if you consider that there's 3 cups combined of sugar and cocoa powder to 1 1/2 cups of butter, the ratio seems less crazy. Plus the chocolate ganache that's added to the recipe replaces some of the confectioners' sugar. This frosting is more creamy and fudgy than a classic buttercream. Hope that clears it up!
