Step 1

Sift the confectioner's sugar, cocoa powder, and espresso powder through a medium sieve into a medium, to remove all lumps. Add the vanilla paste and 2 tablespoons of the non-dairy milk, and whisk until smooth. Lift the whisk from the glaze: the glaze should stream smoothly and slowly from the whisk. If too thick, whisk in another teaspoon and retest. If too thin, whisk in another teaspoon of sugar or cocoa powder.

Step 2

Use immediately. If glaze stiffens during use, add a very small amount of non-dairy milk and whisk until smooth.
