Expert Baking Tips on how to make buttercream for cakes.
Although this recipe of buttercream icing is super easy, here are just a few expert tips i'd recommend:
- Mix your vegan butter with an electric whisk for 5 mins, until pale and fluffy. This should double the butter's volume and help lose its yellow color.
- Once the butter is pale and fluffy add ½ of the icing sugar and beat for a further 5 mins after each addition
- If you’re using vegan spread/margarine you wont need to add any milk/water as spread has a high water potential anymore and your buttercream will likely split.
- If you find that your buttercream is still too loose after the 2nd addition ½ of icing sugar, add 2 tablespoon of milk of choice at a time until you’ve reached your desired consistency.
- If you use block butter make sure it is at room temperature before beating, as this will likely create lumps in your buttercream.

Buttercream how to make
Ingredients for buttercream without vanilla extract
Here's everything I used to make the best dairy free buttercream
Vegan butter- You can use either vegan block butter or margarine. Visit my FAQs below where I explain how to make buttercream using margarine.
Plant-based milk - Only necessary if your buttercream is too stiff. This can also be substituted for the flavor of buttercream you plan to use like strawberry jam/lemon juice
Icing sugar- This will help stabilize the buttercream and add sweetness.
How to how to make a buttercream cake - Step-by-step instructions
Like every buttercream/frosting, begin by creaming the butter (plant-based) on its own for 5 mins until pale and fluffy. Once the butter is pale and fluffy add ½ of the icing sugar and beat for a further 5 mins.

Add the remaining icing sugar and beat for a further 5mins.
Once the buttercream is light, pale and fluffy you can now use it to fill and ice your cakes. If you want to ice a layered cake, I'd recommend fully coating the cake in buttercream - this will lock in all the crumbs, and refrigerate for 30 mins. This is known as a crumb coat.
Then ice again with a second layer of buttercream smoothing it out to produce a nice neat finish.

You can also leave the cake with 1 coat of buttercream for a semi naked look, or dollop all the buttercream at once without crumb coating and instead create dips and flicks in the frosting for a more rustic look.
Flavor Variations and Mixins
There's so many different flavors you can make with this easy dairy free buttercream. Here are some examples:
Caramel
Simply fold in some caramel into your buttercream for a more sweetened frosting or add a sprinkle of sea salt for a little balance. This would work really well for a chocolate and caramel cake, coffee and caramel or just a caramel cake in general!
You can use my easy caramel recipe here [link] that takes less than 10 mins to put together! Perfect to make when you're waiting for your cake to bake.
Chocolate
This easy simple vegan frosting also makes a delicious buttercream for chocolate cake. To go the extra mile you can create a little dip in your buttercream when layering your cakes and fill it with some ganache. Which is extremely simple to make and can be made in the microwave!
To make dairy free chocolate buttercream use these measurements: 20g of cocoa, 150g vegan/dairy free butter and 220g icing sugar and follow the same method in this recipe.
Cream Cheese
If you wanted to make buttercream with cream cheese then I’d recommend following my foolproof vegan cream cheese frosting recipe [link] that goes brilliantly with carrot and red velvet cake! [link]
