Soft and Moist Homemade Chocolate Mayonnaise Cake
This Chocolate Mayonnaise Cake Recipe whisks together cocoa, hot water, and full fat mayonnaise for a deep, fudgy crumb that stays moist for days.

Ingredients
Equipment
Method
- Preheat the oven to 350°F and grease and line a 9 by 13 inch pan.
- Sift the flour, sugar, cocoa, baking soda, and salt together.
- Whisk the mayonnaise and vanilla, then whisk in the hot water and espresso powder.
- Add the dry ingredients in two parts and whisk until just combined.
- Pour into the pan and bake for 28 to 32 minutes, until a toothpick shows a few moist crumbs.
- Cool in the pan for at least 1 hour.
- Beat the butter for 2 minutes, then beat in the powdered sugar, cocoa, milk, vanilla, and salt until fluffy.
- Spread over the cooled cake and chill for 15 minutes to set.
Use full fat mayonnaise and water just off the boil; light mayonnaise makes the cake gummy and tangy, and lukewarm water gives a weaker chocolate flavor.
Notes
- Sift the cocoa powder to avoid dry lumps.
- Mix only until the flour disappears, for a tender crumb.
- Cool the cake completely before frosting.
