All you need is a few pantry staples to make this super chocolaty and delicious Small-batch Chocolate Frosting.
In a medium bowl, beat softened butter until light and fluffy. Add remaining ingredients and beat until well-combined and fluffy. Add more milk by the 1/4 teaspoon if necessary until frosting reaches your desired consistency.
*If you need to use salted butter, just omit the salt in the recipe.
