Are you a looking to make a birthday cake for someone who is following a plant-based diet? You’ve come to the right place! Our friend Sarah ( is here to share with us how to make a vegan birthday cake, including the replacement ingredients you’ll need and the steps to follow!

Whether you’ve been vegan for years, or are just dipping your toe in the plant-based pond, it’s easy to make a delicious cake that you (and your guests) are sure to enjoy.


Vegan Birthday Cake Ingredients:

Got a beloved birthday cake recipe you love? It’s easier than you might think to make it suitable for a vegan diet! Here are the main replacements you’ll want to consider.

  • Where you would usually use dairy milk, switch it out for a plant-based milk (e.g. almond milk, soy milk, oat milk). The same goes for butter – replace with a plant-based spread.
  • Where you would usually use eggs, use Apple Cider Vinegar. Visit our vegan ingredients post to learn more about egg replacements!

How Sarah made her vegan chocolate cake:

  1. Grease and flour two 6” cake tins and line with parchment paper. 
  2. Pre-heat oven to 350°F/180°C. 
  3. In a small bowl, combine plant based milk and apple cider vinegar and stir to combine. Set aside. 
  4. Whisk together sugar, flour, cocoa, baking powder, baking soda and salt in a large bowl and combine.
  5.  Add milk, oil, coffee and vanilla. Mix with a whisk until everything is just combined.
  6. Pour the batter equally into the cake pans and bake for 30-35 minutes. 
  7. Remove the tins from the oven and allow to cool completely in the cake tins before transferring them onto a cooling rack.

Vegan Vanilla Buttercream Ingredients:
