This vegan lemon cake with velvety lemon buttercream frosting is perfectly moist and spongey and will make all your lemon cake dreams come true!


For the Vegan Lemon Cake:

  • 2 and 1/2 cups (312g) + 2 Tbsp All Purpose Flour
  • 1 and 1/2 cups (300g) White Sugar
  • 1 and 1/2 tsp Baking Soda
  • 3/4 tsp Salt
  • 1 and 1/2 cups (360ml) Soy Milk (or other non-dairy milk)
  • 1/2 cup (120ml) Canola Oil*
  • 1 Tbsp White Vinegar (or Apple Cider Vinegar)
  • 1 tsp Vanilla Extract
  • 3 tsp Lemon Extract
  • 2 Tbsp Lemon Zest*

For the Lemon Buttercream Frosting:

  • 4 and 1/2 cups (540g) Powdered Sugar
  • 1/2 cup (112g) Vegan Butter
  • 2 tsp Lemon Extract
  • 3 and 1/2 Tbsp Lemon Juice*

For Decoration:

  • Lemon Zest


  1. Preheat the oven to 350°F (180°C).
  2. Spray two 8 inch cake pans* with non-stick spray and line the bottoms with parchment paper. Set aside.
  3. Sift the flour into a mixing bowl and add the sugar, baking soda and salt. Then add the soy milk, oil, vinegar, vanilla, lemon extract and lemon zest. Whisk with a hand whisk briefly until nicely combined and no big lumps remain. Don’t overmix, tiny lumps are okay.
  4. Divide the batter between the two cake pans and place into the oven to bake for 30 minutes or until a toothpick inserted into the center of one of the cakes comes out clean.
  5. Remove the cakes from the pans and place onto a wire cooling rack to cool completely before frosting.
  6. Prepare your frosting by placing the powdered sugar, vegan butter and lemon extract and lemon juice* into the bowl of an electric mixer. Start off at slow speed, gradually increasing speed until thick and smooth.
  7. Frost the cooled cakes and decorate with lemon zest.


*You can switch the canola oil for another vegetable oil if you prefer. We have made this with various oils including extra virgin olive oil and it has come out great.

*2 Tbsp of lemon zest is from about 2 lemons, but it does depend on the size of the lemons, if it’s a large lemon you might get 2 Tbsp worth of zest from 1 lemon.

*You might not need all the lemon juice in the frosting. I used all of it, but how much you need will largely depend on the brand of vegan butter you use. If you use a firmer type of vegan butter (lower water content) you will need more lemon juice, whereas if it’s more of a soft spread (higher water content) you may need less. So this will require a little flexibility.

*This cake recipe can also be made in 9-inch cake pans with no other changes. The layers will be slightly thinner, but perfect! The cooking time will be the same.
