No Dye Black Frosting (that tastes amazing!)

This frosting uses only black cocoa powder to achieve the deepest and most beautiful black color. It is, by far, the best black buttercream I've ever tasted. To make it, I cook the black cocoa with sugar to create a syrup that is then combined with butter. This creates a creamy frosting with a buttery Oreo flavor that pipes and frosts smoothly onto your cakes. 

HEADS UP, this frosting uses my Sugarologie Method for frostings, which means it's one of the more difficult recipes on this site.

It requires weighing ingredients, cooking a syrup to a precise temperature, and knowing how to use the stand mixer to emulsify the butter. This will need an instant read thermometer, scale, and stand mixer. If you've made a Swiss or Italian meringue buttercream, you should be ok with this recipe. If you haven't attempted an emulsion buttercream before (Swiss meringue, Italian meringue, German, French, etc.) just be sure to read everything carefully and start small before trying the larger quantities of frosting.

I've added a one-cup recipe as a tester if you want to try out this frosting first.

I don't like to stratify bakers for attempting my recipes, but I just you like to know before you start that this is not a beginner-type recipe. But as always, I will give you every detail I know about this process to help you succeed.

Ultimately, I believe that if you're ready to learn, I'm ready to help you. Let's do this.

Does this frosting stain your teeth/tongue?

Ah yes, the most common question when it comes to black frosting. This frosting uses only black cocoa powder and no food dye. So if you like eating Oreo cookies, it's the same thing. Yeah, maybe you'll get some crumbs from the cookies between your teeth, but it typically doesn't "stain" like frostings with food dye.

Gel food coloring is comprised of water-based super concentrated color pigment. If the baker doesn't homogenize the food dye thoroughly, what you get are patches of super-concentrated droplets unevenly distributed in the frosting. The frosting is primarily fat-based (butter) and so it may not look like there's dye but its hiding everywhere.

Once the frosting hits your mouth (your saliva is water-based), and the butterfat melts, the water-based food dye is quickly disbursed (kinda explodes) everywhere and dyes everything black in your mouth.

What is black cocoa powder?


It’s a type of cocoa powder that’s been alkalized, which gives it a deep black color and smoky, intense flavor.
Here is a summary of unsweetened cocoa powders you may encounter in the baking world:

For the most part, cocoa powders are not interchangeable unless the recipe states specific instructions. See how the pH changes based on the type of cocoa powder? Depending on the other ingredients in your recipe, this can affect the texture, rise, and overall quality of your baking.

For this recipe, you will need black cocoa, which is hard to source, so I buy mine online. You can buy the one I use in my videos (here from Amazon). King Arthur Flour also has excellent baking products, including their black cocoa here. (Though I've not used this one myself.)

What ingredients do you need for my black frosting?

Black cocoa powder is an alkalized version of natural cocoa, giving it a rich and super black color. (Here is the one I buy.) Alkalization is a process used in chocolate production to change the specific properties of chocolate products, including color, flavor, solubility, and pH. (Alkaline products have a higher pH or are “basic” or “alkaline”) I’m using it specifically for its color, which is a rich black, but this also imparts a slightly bitter flavor to the frosting. You can correct this using cream of tartar, down below.

White granulated sugar is the sweet ingredient for this frosting. I use granulated because we’re going to dissolve the sugar in the water anyways, and it’s easier to use than powdered. The sugar dissolves and melts a little during the heating step, creating a syrup and giving the finished frosting a smooth texture and glossy appearance. 

Salt is the flavoring agent for this frosting. I always use unsalted butter so I can customize the flavor at the end. Don’t skip this - salt also helps balance out bitter flavors, and this will help make the frosting taste more like an Oreo.

Water is the liquid ingredient that helps cook the cocoa powder and dissolve the sugar. A portion of the black cocoa powder is made of starches, which break open and swell when placed in hot water, creating a thicker and smoother consistency for the syrup. 

Cream of tartar is an acidic powder that is a by-product of wine production. It contains tartaric acid, which can help neutralize the alkaline flavor when using black cocoa powder. I’ve trained myself to taste for alkaline flavors when baking because that’s often a sign of a leavener imbalance, so I’m pretty sensitive to it. If it doesn’t bother you, you can skip this ingredient.

Unsalted butter is the fat source of this frosting, and it mellows the chocolate flavor and adds stability to the finished frosting. Make sure the butter is very cold before adding. This helps equilibrate the temperature of the sauce, which is very hot from cooking. The cold butter brings the temperature down faster and prevents the butter from getting too warm. Heating butter past a certain temp (around 170F) can mess with the proteins, which help pull the frosting together (also called emulsifying) in the end. Don't worry about these details too much, just make sure the butter is frozen in the first step I outline in the recipe, below.

How stable is this black frosting?

This is a new type of frosting that I've developed. I've experimented with it for the past few months. Here are my observations:

  • It will seem thin and loose and first, but will thicken as it stands. I believe this has to do with the sugar syrup settling within the buttercream. If you can make this frosting the day ahead, you'll see if thicken overnight. Just keep it in a covered container at room temperature.
  • If you want to use it right after making, that's fine too. It pipes beautifully and frosts nicely for fillings. It has a super smooth texture, especially if you use the immersion blender trick. The texture is like a denser, slightly soft Swiss meringue buttercream. If you ever watch bakers frost cakes with a Swiss meringue buttercream that almost looks like it's going to slide off the cake (but never does) that's how this one feels.
  • After you frost your cake, if you want it to set even quicker, just place it in the fridge. The timing will depend on the size of your cake, but if it's a 6 or 8 inch round, 30 minutes should be sufficient.
  • I've had many many bakers send me pictures of their finished cakes with this frosting. For the most part, I'm seeing small mini cakes up to what looks like an 8 inch round tall (3-4 layers) of cake. Some people have asked me if this would be suitable for a wedding cake. That I'm not sure of - I'm not a cake decorator nor do I sell my cakes, but functionally and structurally, I know that the butter content and syrup stage that we cook this to will lend great stability, much like a condensed milk buttercream (Russian Buttercream).

    I have had pro bakers make wedding cakes with other recipes of mine. If you do this, I'd love love love to see the results. Many of you are so talented when it comes to cake decorating and I love seeing your art.

Step-by-Step

NOTE: you will need an accurate thermometer (instant read preferably) and a stand mixer. Optionally, you may need an immersion blender to achieve a shiny jet black. Some have also told me that a food processor works as well.

Step 1: Cut and chill the butter cubes.

Cut the butter into chunks and chill in the freezer for at least 30 minutes.

Step 2: Cook the starches in the cocoa powder.

Add the black cocoa powder and water to a pan (2a). Turn heat onto low/medium-low and whisk the cocoa powder into the water until it's disbursed throughout (2b). Cook until you see the tiniest bubbles start to form and a bit of steam rising.

Add the sugar and whisk until fully dissolved (2c).

Step 3: Cook until syrup reaches 230-234°F (110-112°C).

Turn to medium-high heat and cook the syrup until it reaches 230-234F. This may take up to 10 minutes. Use a spatula to scrape the sides if you see any cocoa powder there.

Step 4: Cool the syrup until it reaches 145-150°F (63-66°C).

Pour the hot syrup into the bowl of the stand mixer (4a). Add about 10% of the frozen butter (about a chunk or two), the cream of tartar, and salt (4b) and stir until all the butter is melted. Keep stirring with the spatula until syrup reaches 145-150°F (63-66°C) (4c).

Then add in the rest of the frozen butter (4d). Stir until the butter is around 80-90% melted (4e).

Step 5: Mix (emulsify) using the stand mixer.

*NOTE* in the pics, you'll see me use the paddle attachment. For smaller quantities of frosting (3 cups and under) this works ok. For above those amounts, use the whisk attachment first because it's going to emulsify much faster for you. Then switch over to the paddle at the end to smooth things out.

Once the butter has melted slightly, using the paddle attachment, pulse on low speed (so butter chunks don't go flying out of the bowl) and once the mixer can manage, mix on low speed until it reaches around 68-75°F (20-24°C). Then adjust the mixer to medium-high speed and mix until the frosting comes together (emulsifies) (5a).

This may take a few minutes, depending on the air temp, the temp of your butter and starting temp of your syrup. The important thing is to identify when it's about to emulsify. Once you see little white dots or bumps (like in 5b), the frosting is about to thicken and will be smooth and creamy (5c).

If your frosting remains syrupy and glossy black, it's likely the temp is still too high. You can check with the thermometer. Ideally, you'll want the syrup to be between 68-75°F (20-24°C) for it to emulsify. If it's to warm, stick in the freezer for no more than 5 minutes just to get a chill on the bowl. Then mix again and see if it will come together.

After the buttercream is nice and creamy, mix for an additional minute on high speed, then mix on low speed to get out any large air pockets and smooth out.

The frosting is now ready to use. (If your final frosting is gray or you want a glossy black, move to the next step.)

Step 6: Homogenize with an immersion blender (optional).

I’ve used an immersion blender as a homogenizer for frostings, usually for piping, because it makes the frosting a little denser and glossier. It works well in this case if you need a super shiny, jet-black color. Just be aware that it does create a denser buttercream, which can feel more buttery when you eat it. 

If you want to a watch videos of me making this frosting, I have a couple.

This is my most recent video that shows the method you'll be using to make this buttercream. In the video though, you'll see me make the red velvet flavor, but again, the method will be very similar.

Also, there is this YouTube video, which is an older version of my recipe technique. I don't use this method anymore, but if you want to see what the buttercream looks like for frosting a cake, you can skip to the end.
