With black cocoa powder and a bit of black gel food coloring, it's easy to make a delicious black buttercream that doesn't stain your teeth!

Ingredients

Scale
  • 2 and 1/2 sticks (283 grams) unsalted butter, room temperature
  • 1 cup (110 grams) black cocoa powder
  • 2/3 cup (60 grams) natural cocoa powder
  • 5 cups (650 grams) powdered sugar
  • 1/3 cup (75 grams) heavy cream, room temperature
  • 1 T vanilla extract
  • About 6 drops of black food gel
  • Pinch of salt (more or less to taste)

Instructions

  1. Combine your unsalted butter, powdered sugar, vanilla extract, heavy cream, both cocoa powders, and salt. Mix on a low speed for about 1 minute before increasing to medium-high speed for 2-3 more minutes. Stop your mixer and scrape down the sides of your bowl toward the center so everything combines evenly. 
  2. Add your food dye before mixing on medium speed for another 1-2 minutes. Frosting's color will deepen  to a light black, almost charcoal, color.
  3. To further darken buttercream, take approximately 1/4 cup (or 50 grams) at a time of your frosting. Heat it in a microwavable bowl for five seconds on medium power. Add this melted frosting back into your main bowl and turn the mixer on again to combine. Continue to heat small amounts of frosting at a time and add it back to your bowl until you’ve achieved a deep black color. I do this twice and then let it rest overnight on my counter, at room temperature. 
  4. Add a few tablespoons of heavy cream or milk to your frosting right before you use it to help loosen and give it a smooth, spreadable texture. Put frosting into piping bag fitted with tip of choice and decorate!

Notes

  • Heating the frosting in small increments activates the black food gel and deepens the color. Read the blog post above the recipe card for more tips on how to intensify the shade of your frosting using both time and heat - they’ll help your frosting become a nice, dark shade.
  • When you're ready to use the frosting, it will likely feel very thick. Cocoa is a drying agent, and so your buttercream will almost certainly need more moisture. Pour in a few tablespoons of heavy cream or milk at a time, whipping your frosting by hand, until it has a spreadable consistency. Then add it to your piping bag!
  • This recipe creates about six cups of frosting, which comfortably fills and coats a three-layer, six-inch cake. Reduce or increase as needed.
