Ingredients
 

FOR THE CAKE
  • 2 cups / 240g all-purpose / cake flour
  • ¾ cup / 75g cocoa powder
  • 1 ½ teaspoon baking soda/bicarbonate of soda
  • Pinch of salt
  • 1 cup / 200g white or brown sugar
  • ¾ cup mayonnaise SEE NOTE 1
  • 1 cup 250ml warm water SEE NOTE 2
  • 1 teaspoon / 5 ml vanilla essence
FOR THE GANACHE ( OPTIONAL)
  • 1 ½ cups / 255g dark chocolate broken into pieces
  • ½ cup / 125ml cream

Method
 

DRY INGREDIENTS
  • Sift the flour, salt, cocoa and baking soda (bicarbonate of soda) in a bowl.
WET INGREDIENTS
  • In a separate bowl, combine the mayonnaise, sugar, water, and vanilla. If you are using coffee to enhance the chocolate flavor, then just add a teaspoon of instant coffee to the water and stir to dissolve.
COMBINE THE WET AND DRY INGREDIENTS
  • Add the wet ingredients into the dry ingredients and stir with a whisk or spatula until smooth and creamy.
  • Transfer the mixture to a greased and lined 8-inch / 20cm square pan.
BAKE
  • Bake in a preheated oven of 320°F / 160°C for about 25 to 30 minutes.
CHOCOLATE GANACHE ( OPTIONAL)
  • Make the ganache while the cake cools.
  • Heat ½ cup /125ml heavy / whipping cream in a pan. Add 100g dark chocolate chips or blocks and whisk until the chocolate is melted and incorporated. Remove from the heat.
  • As the ganache cools, it will thicken. Add more chocolate if you prefer a thicker consistency. The cake must be completely cooled before you pour over the ganache. Allow it to set before slicing and serving.

Notes

  1. For me, any type of mayonnaise works with this bake. I have tried them all, the mayonnaise containing eggs, egg-free, full fat and light. These all work perfectly. For this recipe and pictures, I have used the egg-free low-calorie mayonnaise. The cake still retained its amazing moisture and tasted great. I also told myself that it is healthier and stuffed my face with a few extra slices ;) Go ahead and use any type of mayonnaise you have or prefer. This cake will turn out irresistibly delicious with whichever you choose.
  2. Adding a teaspoon of instant coffee to the water in the recipe will create a deeper and richer chocolate flavor. This is totally optional. Feel free to leave out the coffee if you prefer using the water without the coffee.
