In a mixing bowl, sift together the powdered sugar and cocoa powder to avoid lumps.
Add the softened butter, milk (start with 2 tablespoons), vanilla extract, and a pinch of salt.
Mix with an electric mixer on low speed until smooth and creamy. Add more milk if the consistency is too thick.
Add black gel food coloring gradually, mixing thoroughly after each addition until the desired black color is achieved. Let it sit for 10-15 minutes to deepen in color.
Use immediately or store in an airtight container in the refrigerator until needed.

Start with dark cocoa powder to achieve a richer black color with less food coloring.
Let the icing sit after mixing; the color darkens over time.
Use gel food coloring for more intense color without altering consistency.
