Notes
Tip: If you peel your zucchini, no one will ever know there is zucchini in these cupcakes!!If you prefer a cream cheese frosting, use this recipe:1/2 cup butter, softened 4 oz cream cheese, room temperature 3-4 cups powdered sugar 1 tablespoon heavy cream or more as needed. In a bowl beat the butter until smooth, add in the cream cheese and mix to combine. Slowly add in the powdered sugar and mix to combine. Add enough cream to get the desired consistency.
