Homemade frosting can be made as a sweet topping for cakes, doughnuts, brownies, and cookies. The most challenging part of making frosting can be finding the right consistency. A frosting that is too runny or too thick will be difficult to spread.

Using a spoon, test the consistency of the frosting. If it sticks to the spoon and runs off slowly, it is the right consistency. If it pour off quickly, it needs to be thickened.

Thicken the frosting by adding 1 tbsp confectioners or icing sugar. Stir, then test the consistency again.

Keep adding icing sugar, 1 tbsp at a time until it is the desired consistency.


For a frosting that is too thick, add a little water.
