Frequently Asked Questions

Can I make this icing without butter?

Yes! Substitute equal parts vegetable shortening or coconut oil (refined for neutral taste). For dairy-free, use full-fat coconut cream instead of milk.

Why does my icing crust over?

Crusting occurs when powdered sugar's cornstarch reacts with air. Prevent it by covering surface with plastic wrap touching the icing, or add 1 tsp light corn syrup to the base mixture.

How do I fix overly sweet icing?

Balance sweetness with acidity: add 1/4 tsp lemon juice or 1 tsp cocoa powder. For buttercream, a pinch of sea salt works wonders. Always adjust in small increments.

Can I color this icing naturally?

Absolutely. Use beet juice for pink, matcha for green, or turmeric for yellow. Start with 1/4 tsp and add gradually. Note: natural colors may fade over time compared to artificial dyes.
