Chocolate Buttercream In A White Pot

My chocolate cake recipe collection on this blog is coming along nicely now, having recently just added a recipe for chocolate traybake. I always pair my chocolate cakes with some sort of buttercream but one thing I’ve never made the time to do is dedicate a whole post to it. And considering buttercream frosting is the best part about cake (at least, it is for me), it’s about time I did!

I figured writing a separate post would be easier than writing the whole recipe out every time I use buttercream because I can simply link to it instead. Plus, I can write a bit more about the best ingredients to use, and other tips that don’t quite fit into other posts.

I’ve tried a few different buttercream methods and recipes but this is the one I always come back to. It’s rich and chocolatey but you can achieve this by only using cocoa powder- no melted chocolate required!

It’s obviously perfect for popping on top of chocolate cakes but it also goes nicely on vanilla cakes, cupcakes and loaf cakes. It keeps well in the fridge, can be frozen and it holds shape at room temperature just fine.

Ingredients and equipment you’ll need

  • Vegan butter or margarine. ‘Butter’ refers to the blocky type and margarine refers to the smooth spreadable type (even though they’re both technically margarine since they’re made with oils). My favourite vegan butter to use is Stork baking block and my favourite margarine is Vitalite. You can use either one for this recipe- just adjust the amount of soy milk you use as the water and fat content will vary between butters.
  • Vanilla extract. This is used to add a little extra flavour. If you want to really intensify the chocolate flavour, you can use coffee instead. Just dissolve 1/2 teaspoon of instant coffee granules in a very small amount of boiling water and let it cool completely. Once it’s cooled, mix it in a little bit at a time until smooth. I recommend adding this before the soy milk so that you know how much liquid you’ll need.
  • Cocoa powder. I used regular cocoa powder but you can use dark cocoa powder if you want a more striking colour.
  • Icing sugar. If you add too much liquid or just want your buttercream to be thicker, stir in some extra icing sugar until you get the desired consistency.
  • Soy milk. This can be substituted for another plant-based milk such as almond or oat milk. The amount you need will depend on the type of vegan butter/margarine you use. Add it in a little bit at a time until you reach your desired thickness.

How to make vegan chocolate buttercream

Step 1:

Add 180g of vegan butter to a large bowl. If you’re using the blocky type, make sure it’s softened at room temperature first.

Stir in 1 teaspoon of vanilla extract.

Step 2:

Measure out 80g of cocoa powder and 300g of icing sugar and have around 100ml of soy milk to hand.

Add the cocoa powder and icing sugar to the bowl with the butter, mixing it in a little bit at a time. Use a splash of soy milk as needed, to loosen the buttercream. You may not need to add it all in (this will depend on the type of butter you use) so add it in slowly.

All The Ingredients Mixed Together In A Bowl

Step 3:

Once all of the cocoa powder and icing sugar has been mixed in, give it a quick mix with an electric whisk or stand mixer. This will increase the volume slightly and make it nice and fluffy.

Top tips

  • If the buttercream is too thick, add more soy milk and if it’s too thin, add more icing sugar.
  • Add a small splash of cold, strong coffee to the buttercream to intensify the chocolate flavour.
  • Use dark cocoa powder if you want a more striking colour.
  • If using vegan block butter, let it soften slightly at room temperature before using.
  • Whisk for a minute or so using an electric whisk to make it airy and fluffy!

FAQ

How much vegan chocolate buttercream does this recipe yield?

This recipe makes enough frosting to cover three 7-inch cakes or 6-12 cupcakes, depending on how much you like to use.

How long will it last?

If you keep it in an airtight container and store it in the fridge, it will keep for around 10 days.

Yes! Again, pop it into an airtight container. Freeze for up to 3 months and defrost in the fridge the night before you plan to use it. Once defrosted, give it another quick whisk to make it fluffy again. Do not refreeze.

Is Becel margarine ok?

Hi Monika, I've never used that before but I think it'll work. You may just need to play around with the amount of icing sugar and soy milk to get the right consistency.
