Buttercream is great to make in the Thermomix, as you don’t have to leave the butter out at room temperature to soften. The Thermomix blades will soften it in 30 seconds!

Ingredient Notes
Note: The ingredient quantities are shown in the recipe card below.
Butter – use unsalted butter chilled straight from the fridge.
Icing sugar – use store bought soft icing sugar. The Thermomix can grind white sugar into icing sugar, but I find it gritty when making buttercream.
Milk – either lite milk or whole milk for extra creaminess.
