Moist, rich vegan carrot cake with a wholesome flavor and gorgeous color. Topped with lemon buttercream frosting and crushed walnuts. Ideal for any special occasion.


For the Carrot Cake:

For the Lemon Buttercream Frosting:


  1. Preheat the oven to 350°F (180°C).
  2. Grease two 7-inch cake pans (See Notes*) and line the bottoms with parchment paper.
  3. Sift the flour, baking powder, baking soda, salt, cinnamon and nutmeg into a mixing bowl.
  4. Add the grated carrot and the brown sugar.
  5. Prepare the flax eggs, by mixing 2 Tbsp Flaxseed Meal with 6 Tbsp Water and allowing to sit for a minute.
  6. In the meantime, add the oil, vanilla and apple cider vinegar to the mixing bowl.
  7. Add the flax eggs.
  8. Mix everything together in the mixing bowl. Have a little patience and let the batter sit for a minute or two so that the carrots can release more water into the batter to enable you to mix it all together.
  9. *If your batter is still too dry to mix after letting it sit for a couple of minutes (and only if it’s too dry to mix after sitting for a few minutes) then add in a little non-dairy milk, only as much as you need to get the batter to a wet enough consistency so that it can mix properly.
  10. Lastly add the chopped walnuts if you want to add them.
  11. Divide the mixture between the two 7-inch cake tins.
  12. Place into the oven and bake for 30 minutes or until a toothpick inserted into the center comes out clean.
  13. Allow the cakes to cool completely on a cooling rack.
  14. While the cakes are cooling, prepare your frosting.
  15. Add the powdered sugar, vegan butter, vanilla, apple cider vinegar and 3 Tbsp of lemon juice to an electric mixer bowl.
  16. Start mixing on low speed.
  17. If your frosting is too thick then add in more lemon juice a drop at a time as needed to get your frosting mix to the perfect consistency. If your frosting ends up too thin, add more powdered sugar.
  18. Add frosting to the top of one of the layers.
  19. Add the other layer on top and complete the frosting of the top and sides of the cake.
  20. Sprinkle crushed walnuts on top of the cake and serve.


*You can also use vegetable oil instead of canola oil. We have also used extra virgin olive oil in this cake and loved it, but some brands can leave an aftertaste.

*This cake also works perfectly in 8-inch cake pans. The layers are slightly thinner but still perfect. Baking time and everything are exactly the same.

*Some commenters have noted that they needed to use a little non-dairy milk to get their batter wet enough. This would depend on how wet your carrots are. Usually if you just let your batter sit for a few minutes, the carrots will release more water into the batter allowing you to mix it properly. If you did this and it is still too dry to mix then just use as little non-dairy milk as you need to get the batter wet enough to mix properly.

*Another frosting that is awesome on this cake is our vegan cream cheese frosting or our vegan lemon buttercream frosting.
