  • In the bowl of a stand mixer or a large bowl with a hand mixer, beat the butter and shortening until light and fluffy, about 3 minutes.
  • Add the powdered sugar 1 cup at a time and continue beating. Scrape the sides and bottom of the bowl with a spatula after each addition. Taste to see if it's sweet to your liking. Add more sugar if you'd like.
  • Add the salt and vanilla and beat again until combined.
  • Using a piping bag, or a spatula, put some frosting onto the bottom of one cake, and top with another, making a sandwich. Repeat with the rest of the cakes.

Notes

Dairy-Free: To make dairy-free whoopie pies, use vegan butter in place of unsalted butter and substitute dairy-free homemade sour milk for the buttermilk. To make sour milk, add 1 tablespoon of distilled vinegar to a 1-cup measuring cup. Fill the cup with plant milk to the 1-cup line and stir. Let sit for 3-5 minutes and then use the sour milk in place of the buttermilk as directed.
