This old-fashioned dessert often ends the meal at my home. My aunt has made this moist, rich sheet cake for as long as I can remember. Not only is it a cake I can quickly make from scratch, but it calls for ingredients I usually have in the pantry. —Kristine Marra, Clifton Park, New York


  • 1 cup all-purpose flour
  • 3/4 cup sugar
  • 1/4 cup baking cocoa
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1 cup mayonnaise
  • 1 cup water
  • 1 can (16 ounces) French vanilla or vanilla frosting


  1. In a large bowl, combine the flour, sugar cocoa, baking powder and baking soda. Beat in mayonnaise and water.
