Dry Ingredients
Icing Sugar: ensure that your icing sugar is lump free. I buy pre-sifted icing sugar. If yours is not, I highly recommend sifting it before you make the buttercream, to avoid any lumps.
Wet Ingredients
Butter: my go-to is unsalted plant based butter that comes in a block, as shown above. Tub butters tend to have a higher oil content and can create a greasy buttercream. Block plant based butter tends to react better in warmer temperatures. If you are concerned about high humidity, you could sub half of the butter with vegetable shortening. Always use room temperature butter when making buttercream. I usually take mine out of the fridge 20 minutes before making the recipe. Sub with dairy butter if you are not dairy free or vegan.
Flavouring: I adore vanilla bean paste in buttercream. Having tried different extracts, I find that the paste gives a more natural flavour and I also love the little specks that are dotted throughout the buttercream. Sub with your preferred flavouring.
Water: to thin down the buttercream slightly, I usually add a small amount of water. You can use milk instead if you prefer. Room temperature water is fine to use.
How to Make Small Batch Vanilla Buttercream
This buttercream takes less than 3 minutes to make once everything is ready. Gather all equipment and supplies. The butter should be at room temperature. I usually take mine out of the fridge 20 minutes before I start the recipe.
To a mixing bowl, add 100g plant based butter, 1 tsp vanilla bean paste, half of the icing sugar and mix together with a hand whisk.
The buttercream will be thick and crumbly at this point.
Add the remaining icing sugar and 20ml of water. This will help to lighten the colour and also thin out the buttercream slightly to a more pipable consistency.
Stir together until the buttercream is smooth and fluffy and all of the ingredients are fully combined.
And that’s how quick and easy it is! Less than 3 minutes to make the perfect small batch of vegan vanilla buttercream. This buttercream is firm enough to pipe swirls on top of the cupcakes or to spread on top with an offset spatula.
