Chocolate Mayonnaise Cake is an old-fashioned, ultra-moist chocolate cake made with a surprising secret ingredient — mayonnaise. It delivers a rich, fudgy texture and deep chocolate flavor without the need for butter or milk, making it simple, dairy-free, and utterly delicious.

Ingredients

  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • ½ cup unsweetened cocoa powder
  • 1½ teaspoons baking soda
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup mayonnaise (full-fat)
  • 1 cup water or brewed coffee
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour an 8-inch round or square cake pan.
  2. In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt.
  3. Add mayonnaise, water (or coffee), and vanilla extract. Mix until just smooth and combined — do not overmix.
  4. Pour the batter into the prepared pan and smooth the top.
  5. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
  6. Allow the cake to cool completely before frosting or serving.

Notes

  • Use full-fat mayonnaise for best texture and flavor.
  • Brewed coffee enhances the chocolate flavor but is optional.
  • Do not overmix — it can make the cake dense.
  • This cake stays moist for several days at room temperature.
  • Top with chocolate ganache or a simple dusting of powdered sugar.
