Icing for cocoa water cake

A week ago I cooked an amazing meal "Turtle Cake". When the preparation of this dessert was at the final stage - watering the folded "turtle" chocolate glaze, I realized with regret that I didn't have chocolate in my house, and it was too late to run for it somewhere. But I was not at a loss and decided to replace the chocolate glaze with cocoa glaze. You probably wonder how to cook it. Well, I'm sharing with you this uncomplicated culinary recipe. So, we start by taking sugar and grinding it into powdered sugar in a coffee grinder or using a blender. Now we sift the powdered sugar and the required amount of cocoa through a sieve. It's better to do this a couple of times. Then add hot water (or milk) to the resulting mixture and quickly mix our mass to a homogeneous consistency. After that, we can add a little butter to our glaze. With its help, we will be able to make the glaze more shiny. When the glaze is ready, we lubricate the confectionery product we need.
