Thermomix Buttercream Icing

This is the best smooth and fluffy Thermomix buttercream made in less than five minutes.

Making Buttercream in the Thermomix is a great way to save time. You don't have to leave the butter out at room temperature to soften - the Thermomix blades soften it in 40 seconds.

This recipe is ideal for decorating my Thermomix vanilla cupcakes.

Recipe Ingredients

Note: The full quantities are shown in the recipe card below.

• Butter - use chilled unsalted butter straight from the fridge, as the Thermomix softens it.
• Icing sugar - to make your own icing sugar, see my blog post on how to make Thermomix icing sugar.
• Milk - either light milk or whole milk for added creaminess.
• Vanilla extract

Step-by-Step Directions

Note: This is a summary of the instructions. The full ingredients and instructions are shown in the recipe card below.

Step 1

Add the cubed butter to the Thermomix bowl.

Step 2

Mix until smooth and creamy.

Step 3

Insert the butterfly whisk, add half the icing sugar, and mix until the icing sugar is incorporated into the butter. Add the remaining icing sugar, vanilla extract and milk and mix until smooth and fluffy.

Storage

Store the buttercream in an airtight container in the fridge for up to one week, or at a cool room temperature for up to one day if you're using it sooner. It also freezes well for up to three months, just thaw overnight in the fridge, then bring to room temperature and re-whip before using.
