Donut glaze recipe: How to make donut glaze for your bakery
Ingredients (batch size for approx. 40–50 pieces):
- 1 kg icing sugar (sifted)
- 250–300 ml water (or milk for a creamier glaze)
- 10 ml vanilla extract (or other flavouring)
Method:
- Combine icing sugar and liquid in a large mixing bowl or stand mixer.
- Add flavouring and mix until smooth and pourable.
- Use immediately to dip or drizzle onto baked or fried products.
Commercial tip: Use water for longer shelf life and easier cleanup. Add milk if you’re glazing on-demand and want a slightly richer finish. For a thicker glaze, reduce liquid slightly or allow it to rest before application.
Glaze flavour ideas to try
While vanilla is a classic, there’s plenty of room to get creative with your flavours and colour variations. Here are a few bakery favourites.
- Chocolate glaze – Add 1–2 tbsp cocoa powder
- Maple glaze – Use maple extract instead of vanilla
- Citrus glaze – Add lemon/orange juice and zest
- Berry glaze – Blend and strain berries, then mix into the glaze
- Coffee glaze – Add 1 tbsp brewed espresso or coffee extract
Use natural food colouring to create seasonal glazes or themed variations for holidays.

Should I use water or milk in the glaze?
Use water if you want a longer shelf life and a cleaner glaze for batch production. Use milk for a richer flavour and creamier texture if you’re glazing to order or for same-day service.
