Notes

- This buttercream recipe is great for filling layered cakes, frosting cupcakes, and piping decorations.
- To store: Frosting should be stored in an airtight container in a refrigerator for 2 weeks and can be frozen for up to 6 weeks. Bring back to room temperature and re-whip before using. Frosted cakes and cupcakes can be stored on the counter for two to three days.
- To color: Use Icing Colors or food coloring to tint frosting to any color without disturbing the consistency of the frosting.
- To cut sweetness: If your buttercream is too sweet, add a pinch of salt. Make sure it dissolves completely once mixed in. You can also opt for 1/2 cup salted butter rather than 1/2 cup unsalted butter to avoid overly sweet buttercream.
