Ingredients
 

Main Ingredients

  • 2 cup all-purpose flour
  • 1.5 cup granulated sugar
  • 0.5 cup unsweetened cocoa powder
  • 2 tsp baking soda
  • 0.75 tsp baking powder
  • 0.5 tsp fine salt
  • 1 cup mayonnaise full-fat for best texture
  • 1 cup hot brewed coffee or very hot water heat helps bloom the cocoa
  • 2 tsp vanilla extract

Instructions

Preparation Steps

  • Heat oven to 350°F. Grease and flour a 9×13-inch pan or line with parchment.
  • Whisk flour, sugar, cocoa, baking soda, baking powder, and salt in a large bowl.
  • Stir mayonnaise, vanilla, and hot coffee (or hot water) in a separate bowl until smooth.
  • Pour the wet mixture over the dry ingredients. Mix gently until just combined and no dry streaks remain.
  • Scrape batter into the prepared pan and smooth the top.
  • Bake 32–36 minutes, until a toothpick in the center comes out with a few moist crumbs.
  • Cool on a rack 15 minutes, then turn out or leave in pan to cool completely before frosting or dusting with sugar.

Notes

Variation: Swap half the hot water for hot coffee to deepen chocolate flavor. For storage, wrap the cooled cake tightly and keep at room temperature up to 2 days or refrigerate up to 5 days; it also freezes well for 2 months.
