Chocolate Cake With Mayonnaise (Printable)

A rich chocolate cake using mayonnaise for exceptional moisture and tender crumb, ready in 50 minutes.

# What You’ll Need:

→ Dry Ingredients

01 - 2 cups all-purpose flour
02 - 2/3 cup unsweetened cocoa powder
03 - 1 1/2 teaspoons baking powder
04 - 1 1/2 teaspoons baking soda
05 - 1/2 teaspoon salt

→ Wet Ingredients

06 - 1 cup regular mayonnaise (not low-fat or light)
07 - 1 cup granulated sugar
08 - 1 cup packed brown sugar
09 - 1 tablespoon vanilla extract
10 - 1 1/4 cups cold water

# How-to Steps:

01 - Preheat the oven to 350°F. Grease and flour two 8-inch round cake pans.
02 - In a large bowl, sift together flour, cocoa powder, baking powder, baking soda, and salt.
03 - In another bowl, whisk mayonnaise, granulated sugar, brown sugar, and vanilla until smooth and well combined.
04 - Alternate adding the dry ingredients and cold water to the mayonnaise mixture, starting and ending with dry ingredients. Mix until just combined—do not over-mix.
05 - Divide the batter evenly between the prepared pans.
06 - Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
07 - Let cakes cool in pans for 10 minutes, then turn out onto wire racks to cool completely. Frost and decorate as desired.

# Expert Advice:

01 -
  • The crumb stays impossibly moist for days, unlike most chocolate cakes that dry out overnight
  • Nobody will ever guess your secret until you decide to tell them
  • It comes together with ingredients you probably already have in the fridge
02 -
  • Over mixing will make the cake tough, so stop as soon as the flour disappears
  • The toothpick test is the only way to know for sure if it is done, so do not rely on timing alone
03 -
  • Room temperature ingredients blend more easily, so set the mayonnaise out about 30 minutes before you start
  • Let the cake cool completely before frosting or the frosting will melt right off
