01 - Combine milk and dried lavender in a small saucepan. Heat gently over low heat until just steaming, not boiling, approximately 2 minutes. Remove from heat and steep for 5 minutes.
02 - Pour the lavender mixture through a fine-mesh strainer to remove buds. Allow the infused milk to cool slightly before incorporating into glaze.
03 - Whisk powdered sugar with 2.5 to 3 tablespoons of lavender-infused milk in a mixing bowl. Add lemon juice if desired for enhanced brightness. Mix until completely smooth and pourable.
04 - If glaze is too thick, add additional milk 1/2 teaspoon at a time. If too thin, incorporate more powdered sugar 1 tablespoon at a time until desired consistency is achieved.
05 - Drizzle or spread glaze evenly over cooled baked goods. Allow glaze to set for at least 10 minutes before serving or storing.
