This simple vanilla glaze comes together in a few minutes. It's great as a doughnut glaze, a bundt or coffee cake drizzle, on cookies, or sweet muffins.
Mix all ingredients in a medium to small bowl. If needed, thin with additional lemon juice or milk to get the desired consistency.
Use immediately, or wrap tightly and refrigerate for up to a week. Cover the surface of the icing with plastic wrap or waxed paper to prevent it from drying out.
