Did you know Oreo cookies are made using black cocoa powder? If you're a fan of this classic cookie, you'll fall in love with the chocolate flavor of this black frosting!
Test the consistency of your frosting with a spatula to see if it’s easily spreadable. If your black buttercream is too thick, add more heavy cream (1 Tbsp at a time). If the frosting is too thin, add in more powdered sugar (1/4 cup at a time).
To deepen color, take roughly 1/4 cup (50 grams) at a time of your now almost-black frosting. Heat it in a microwavable bowl for five seconds on medium power.
Add this melted frosting back into your mixing bowl, and turn the mixer on again to combine. Continue to heat small amounts of frosting to mix it and add back to your main bowl until you have your desired shade of black.
