This is the perfect Small-batch Vanilla Frosting recipe. It's rich, delicious, and so easy to make.
In a medium bowl, beat softened butter until light and fluffy, 30 seconds to 1 minute. Add powdered sugar, 1 teaspoon of milk or cream, vanilla extract, and salt.
Beat until smooth. Add up to 2 additional teaspoons of milk until frosting reaches your desired consistency.
To substitute vanilla bean for extract, use 1/2 to 1 inch of vanilla bean, to taste. For paste, follow the substitution guidelines on the jar, as it varies from product to product.
