This recipe for Chocolate-Mayonnaise Cake with Ganache Drizzle makes a beautiful, light-textured cake that’s incredibly moist. The Ganache Drizzle finishes it off with the perfect amount of indulgence! I had an English friend asked me if I’ve ever had a mayonnaise cake. To be honest, I’d never heard of it before. She told me it was super moist and the best chocolate cake she’d ever had.
Considering that mayonnaise is mainly eggs and oil, I could see how it would work. I looked it up and most recipes I came across, completely omitted any eggs or fat.
I wasn’t sure how it would work but set to create a recipe. I originally planned to just use cocoa powder and no chocolate in the recipe. This was only because I knew I wanted to make a ganache icing and I only had 7oz of chocolate on hand.
While I was in the middle of making this cake I had a food order delivered which had chocolate chips in it so I melted some and added it. I’m really glad I did because it really needed it.
The cake turned out much lighter in color than any other chocolate cake I’ve ever made and the texture was super moist and dense.
I can’t stress enough how important it is to wait until the cake is completely cool before handling it. I was short on time and moved it too soon and it broke in several places.
Luckily, it was after I shot the photos and the friends I made it for are used to my cakes already being cut by the time I serve it (something that comes along with having a food blog). The Ganache Drizzle was the star of the show. It added something special to the cake and it was a big hit. Now that I’ve made it this way, I can’t imagine making it any other way.
