Chocolate cake with an unlikely ingredient (gluten-free; dairy-free; vegan)

Happy Easter! I hope the sun is shining where you are this holiday weekend. I had intended to post this feature a little ahead of the weekend but time has run away with me this week. Actually, to be completely honest, I was ready to post it yesterday until I realised what the date was, and given the unusual ingredient, I thought that my recipe might not be taken seriously. So, here we are at the end of the week, and I’m ready to reveal all 🙂

This is one of the easiest chocolate cake batter recipes you will come across, so even if you don’t have the time to make the chocolate ganache and other finishing touches, do keep the cake batter recipe for trying at a later date with your own icing and decorations. What makes this cake batter a bit alternative is the addition of plain vegan mayonnaise. But, it’s not that weird an addition when you think about it, mayonnaise is just an amalgam of fat and liquid which are 2 of the main ingredients in a cake batter.

However, I must emphasise the word “plain”. Please do check the ingredient list for mustard and/or garlic or anything else highly flavoured i.e. choose a mayonnaise with the least amount of flavouring possible. Taste the mayonnaise before you add it to the other ingredients, just to make sure. If you’re not vegan, a plain egg-based mayonnaise will work as well. The same goes for anyone who is not gluten-free, you can use ordinary plain white wheat flour.

Because it’s Easter and I love marzipan, I have added an additional layer of chocolate marzipan before the ganache gets poured over, and I used some more to make the decorations. If you don’t like marzipan just pour the ganache directly over the cake, and decorate with readymade chocolate decorations. Or you add cocoa powder to ready-to-roll (fondant) white icing in the same way as in the recipe below, and use this to make flowers and eggs instead.

The cake is deliciously rich, moist and flavoursome. It freezes well if you have any left. Once cut, it is best stored in the fridge or at a cool room temperature for up to 5 days. I hope you enjoy it.

Serves: 10-12

Ingredients

  • 140g gluten free plain flour blend
  • 65g cocoa powder plus extra for dusting
  • 17g gluten-free baking powder
  • ¼ tsp xanthan gum (optional but it does help hold the crumb together)
  • 65g ground almonds
  • 175g soft light brown sugar
  • 190g plain vegan mayonnaise
  • 2 tsp vanilla extract
  • 300g marzipan
  • 2 tbsp smooth apricot jam
  • 250g dairy free dark chocolate (I use 54% cocoa chocolate but use darker if preferred)
  • 125g plant-based block margarine

1. Grease and line a deep 20cm round tin. Put the flour, 50g cocoa, baking powder, xanthan gum and almonds in a bowl and mix together until well blended. Stir in the sugar, and crush any lumps.

2. Make a well in the centre, and add 175ml cold water and the mayonnaise, then beat everything together until smooth and thoroughly blended. Spoon into the tin, smooth the top and put the tin on a baking tray.

3. Bake for about 1hr to 1hr 10 minutes until risen and firm to the touch – test the centre with a skewer, if it comes out clean, the cake is cooked. Leave for 10 minutes before turning on to a wire rack to cool completely. The cake may sink slightly in the middle. When the cake is cold, turn it upside down and peel away the lining paper.

4. While the cake is cooling, make the marzipan. Knead the marzipan a few times to soften it. Flatten slightly then add 1tsp of the remaining cocoa powder. Fold the marzipan over the cocoa and keep kneading until the cocoa is distributed evenly in the marzipan. Repeat the process, adding the cocoa gradually, until it is used up.

5. Cut off a 75g piece and put to one side. Lightly dust the work top with more cocoa powder and roll out the remaining marzipan to fit the top of the cake. I use the tin base as a template to cut out a neat circle.

6. Brush the cake with apricot jam and sit the marzipan circle on top. Any marzipan trimmings can be added to the reserved piece and used to make decorations.

7. For the ganache, break up the chocolate and place in a saucepan with the margarine and 50ml water. Heat gently, stirring, until melted together. Remove from the heat, stir well, then leave to cool for about 20-30 minutes. You want the mixture to thicken sufficiently so that it doesn’t run straight off the cake when you pour it over.

8. Once thickened, sit the cake and wire rack over a tray or board. Slowly pour the ganache over the top of the cake from the middle, in a thin stream. If you want a completely smooth finish, continue pouring so that the ganache floods down the sides of the cake to coat them. Alternatively, pour and spread for a more textured appearance. Any ganache that sets on the tray underneath can be scooped up and remelted.

Once the cake is covered, the ganache will set quite firmly if chilled, then you can prise the cake from the rack. If you have a cool kitchen, leave the cake to set naturally; the ganache will be slightly softer and it will be easier to remove it from the rack. Make the decorations while the cake is setting and then all you have to do is decorate the cake, serve it up and take in all the praise 🙂

  1. I have used beet in chocolate cake before but never mayonnaise! I am curious. I would have to make my own, but without mustard, I am not sure if it would take. To be tried.
    Your cake with its different layers and textures looks gorgeous.
    Happy Easter, Kathryn!

    1. Happy Easter to you Joëlle. I would have thought that homemade would work ok as long as you have sufficient oil and liquid. If you eat eggs which I think you do, then it would work fine. The sun has been shining here today and I have been planting vegetable seeds which felt very good 🙂
