How to Make Chocolate Royal Icing

Dreams do come true! There IS a way to get chocolate flavored royal icing for your cookies, but it takes a little trial and error. So we spent some quality (and chocolatey) time in our test kitchen to find out what works and why!

Let's start with a primer on what not to do.

If you made classic royal icing, replacing the powdered sugar with cocoa powder, you would get an icing that would be hard to work with, never harden, and be runny.

This would happen because cocoa powder has natural oils (even though it's dry, yes, it has oils!) that would stop your icing from setting. So while that would be true chocolate icing, what you actually want is royal icing with a bit of chocolate in it.

The solution is to make a standard royal icing, and add in the smallest amount of cocoa powder possible to get the best chocolate taste and color.

This is exactly why Genie's Dream brand made their Infinitely Black Cocoa No 1. It's different than average cocoas because it's:

  • Super dark black, so you get better color using less.
  • Strong cocoa flavor.
  • Very finely milled, to blend better into icing.
  • Unsweetened.

It's because of these qualities that we use it in our chocolate royal icing recipe. Follow the recipe below and the result will be a chocolate-y royal icing that sets firm.

Directions

If you are making a full batch of icing, add the cocoa at the same time you add the second half of your powdered sugar.  This will keep you from adding any more electric-mixer time to your icing, reducing the risk of overmixing.  Note: you may need to start with just a touch more water to help with the extra powder.

If you are making a small batch, you can use fresh or stored royal icing and mix the cocoa in by hand.

If you're looking for a black icing, you can add black gel color to your icing after the cocoa is incorporated.  You won't need much, since you'll be starting with such a nice dark color!
