Ingredients

  • 1 cup granulated sugar (200 grams)
  • 1/2 cup mayonnaise (120 grams)
  • 1 large egg
  • 1 teaspoon vanilla
  • 1 1/4 cups all-purpose flour (160 grams)
  • 1/2 cup unsweetened natural cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt, scant (you can use as little as 1/4)
  • 3/4 cups lukewarm water

Sour Cream Chocolate Icing

  • 4 tablespoons butter, unsalted or salted (56 grams)
  • 1/3 cup cocoa powder, natural (30 grams)
  • 1 ½ cups sifted confectioners sugar (150 grams)
  • 1/3 cup sour cream, bring to room temperature (80 grams)
  • 1 teaspoon vanilla

Instructions

  • Grease an 8 inch square metal or glass pan (cooking spray is fine).
  • Combine first 4 ingredients (sugar, mayonnaise, egg and vanilla) in a mixing bowl. Stir well.
  • Sift flour, cocoa, baking powder and salt together, then add to the mayonnaise mixture. Stir in the water and beat with a spoon or scraper until well-blended.
  • Transfer mixture to the baking pan and bake at 325 degrees for 30 to 35 minutes. For cupcakes, bake at 350 degrees for 15 minutes.
  • To make the frosting, soften to butter so that it is mushy and almost but not quite melted. Sift the cocoa powder with the confectioners' sugar. Add the confectioner’s sugar mixture and sour cream alternately to the chocolate mixture and beat with a handheld mixer until fluffy, scraping sides of the bowl. Beat in the vanilla.

Notes

  • You can use a metal pan or a glass baking dish.
  • You can mix the batter with a spoon or scraper.  No need to use an electric mixer.
  • Since the recipe calls for baking soda and no baking powder, I use natural cocoa, which is more acidic than Dutch process. I still haven't tried this with Dutch process.  
  • You can make the frosting without an electric mixer, but it's easier with one.  A handheld should be fine.
