Step 1

Gather all ingredients. Dice the butter and cream cheese into small pieces and let them sit out at room temperature for 1-2 hours, until softened. They're ready to use when you can press a fingerpring in them.

Step 2

Place all ingredients in a mixing bowl, starting with 1 tablespoon of lemon juice.

Step 3

Beat together until fluffy, adding more lemon juice as necessary to make it smooth and creamy. Frost on cupcakes, cakes or cookies and serve.
