Vegan Chocolate Marble Cake


  • 2.5 cups plain flour
  • 4 tbsp cornflour
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 3/4 cup vegan sugar*
  • 1/4 tsp nutmeg
  • 2 tbsp ground flax seed mixed with 5 tbsp cold water
  • 1.5 cup dairy free milk
  • 2 tsp vanilla extract
  • 1 tbsp apple cider vinegar
  • 1/2 cup veg oil
  • 4 tbsp cocoa powder
  • 5 tbsp hot water


  1. Preheat oven to 180•c/360F and grease a loaf tin with a little oil.
  2. Add flour, cornflour, baking powder, soda, sugar and nutmeg to a large bowl and stir well.
  3. In a small dish mix flax seed with water to form a gel. Add flax gel, dairy free milk, vanilla, apple cider vinegar and veg oil to the bowl and stir briefly to incorporate. Don’t over mix.
  4. In a medium mixing bowl, mix cocoa with hot water. Pour in half of the vanilla batter and stir well. Using a tablespoon, alternate spoons of batter into the loaf pan until all batter is used up. For extra swirls, use a chop stick to swirl the top layer of the cake.
  5. Bake for 1 hour, until a toothpick comes out clean. Allow to cool fully before slicing.


*Not all sugar is vegan as some companies use bone char to process the sugar. Organic sugar is, however, generally speaking vegan and certain countries have banned that filtering process, so if you want to be sure yours is vegan, simply google the brand name and “is this vegan”.


  1. This looks incredible!! We’re an oil free household. Do you have a suggestion for a replacement for the 1/2 cup of oil? I’m thinking an applesauce & nut butter blend but curious if you’ve tried alternatives. Thanks!

    • Hi Emma! You could try oil-free vegan butter or nut butter (like almond or cashew) instead. It may not result in the exact same texture, but should still be good:) The apple sauce (or mashed banana) and nut butter blend sounds good too (but again, it might result in a slightly different texture/taste profile).

    • Hi, Imogen! Thanks for your comment! Many people have the same question, so thanks for letting us clarify. Corn flour is NOT the same as corn starch. Corn flour is more like a finely ground cornmeal! I hope that helps!

      • Might be a good idea to specify that in the recipe itself. I only just saw this comment, having already used cornstarch and my cake having been in the oven for the last 30 min.
        Usually I’ve seen people use ‘corn flour’ (two words) to mean cornmeal, and ‘cornflour’ interchangeably with cornstarch.

  2. looks gorgeous . whats the size of your loaf tin.?? this looks like too much batter for my 8*5 inch

  3. Hi. Regarding the ‘cornflour’ thing, think it depends on the country. Here in Australia cornflour is definitely not “finely ground cornmeal” its a white GF flour.
