Versatility is the name of the game with this icing. Substituting liqueur, milk, or another citrus juice for the lemon juice lets you customize the icing for a variety of cakes. It's especially delicious drizzled atop loaf cakes.
- 4 1/2 cups confectioners' sugar
- 1/4 cup plus 2 tablespoons fresh lemon juice (from 2 lemons), plus more if needed
Whisk together sugar and lemon juice until smooth. If icing is too thick, add more lemon juice, 1 teaspoon at a time. Use immediately.
