Notes
-
For best flavor distribution, rub the lemon zest into the powdered sugar before mixing.
-
2 tsp zest gives vibrant lemon flavor and natural color without overpowering sweetness.
-
If frosting becomes too soft, add powdered sugar 1/4 cup at a time.
-

- If using unsalted butter add 1/4 tsp salt when you cream your butter.
