Ingredients
Dry mix
- 4 cups powdered sugar (confectioners’ sugar)
- 1 cup powdered milk or powdered heavy cream
- ½ cup cornstarch
- ½ teaspoon fine sea salt
- 1 tablespoon vanilla powder or vanilla bean powder
Optional add-ins for the dry mix

- Citrus: 1 tablespoon dehydrated lemon, lime, or orange zest powder
- Spiced: 1 teaspoon cinnamon, ½ teaspoon nutmeg, ¼ teaspoon cloves
- Coffee: 1 tablespoon espresso powder
Buttercream
- 1 cup softened unsalted butter (or shortening for a dairy-free option)
- 2½ cups dry mix
- 3 to 4 tablespoons liquid (milk, heavy cream, or flavored syrup)
Glaze
- 1 cup dry mix
- 2 to 3 tablespoons water milk, or citrus juice
Equipment

Directions
- Mix the dry ingredients (and any add-in), then store.
- Buttercream: beat the butter until creamy, then slowly beat in 2½ cups of the mix on low speed. Add 3 to 4 tablespoons of liquid until it reaches the thickness you want, and whip for 2 to 3 minutes until fluffy.
- Glaze: whisk 1 cup of the mix with 2 to 3 tablespoons of liquid until smooth, adding more or less liquid to suit drizzling or spreading.
