Chocolate Mayonnaise Cake is an ultra-moist, rich chocolate cake made without butter or milk, using mayonnaise as the key ingredient. This classic, budget-friendly recipe dates back to the Depression era and remains popular for its simplicity and surprisingly decadent texture.

Ingredients

  • 2 cups all-purpose flour
  • 2/3 cup unsweetened cocoa powder
  • 1 1/2 tsp baking soda
  • 1 cup granulated sugar
  • 1 cup full-fat mayonnaise
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 cup water (hot or room temperature)
  • Optional: Chocolate frosting, powdered sugar, whipped cream, or fresh berries for topping

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch pan or two 8-inch round cake pans.
  2. In a large bowl, whisk together flour, cocoa powder, baking soda, and sugar.
  3. Add mayonnaise, eggs, and vanilla extract. Mix until fully combined.
  4. Gradually stir in the water until a smooth batter forms.
  5. Pour into prepared pan(s) and spread evenly.
  6. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
  7. Cool completely before frosting or serving.

Notes

  • Mayonnaise adds moisture and replaces the need for butter or milk.
  • Use full-fat mayo for best texture—light versions may yield a drier cake.
  • Replace half the water with coffee for a richer chocolate flavor.
  • For cupcakes, bake for 18–22 minutes at 350°F (175°C).
  • Store frosted or unfrosted; cake stays moist for days.
