Instructions
Butter Mixture: To a medium mixing bowl, add the butter, maple syrup, vanilla extract, and salt. Beat with an electric mixer at medium speed until well-mixed.
Powdered Sugar: Add half the powdered sugar to the butter mixture. Mix at low speed until lightly incorporated. Add the remaining powdered sugar. Mix at low speed for 30 seconds and then increase to medium-high speed. Mix until smooth and creamy. Scrape the sides of the bowl as needed to incorporate all the powdered sugar.
Notes
Storage: Store leftover maple buttercream frosting in an airtight container in the refrigerator for up to one week.Adjust the consistency: For a thick frosting, add more powdered sugar a little at a time until you reach your desired consistency. For a thinner icing-like frosting, use less powdered sugar or add a bit more maple syrup or a splash of milk as needed to thin.
