  • 1 teaspoon vanilla extract for icing
  • 1 pinch salt
  • 5 cups powdered sugar
  • 4-7 tablespoons milk or evaporated milk to achieve desired consistency

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C). Grease a 9 by 13 inch baking pan.
  2. In a large mixing bowl, whisk together the flour, sugar, cocoa powder, and baking soda.
  3. Add the milk, mayonnaise, and vanilla extract; stir until smooth.
  4. Pour the batter into the greased pan and bake for 40 to 45 minutes, checking with a toothpick for doneness.
  5. Allow the cake to cool.
Icing
  1. In a medium bowl, beat the butter, sifted cocoa powder, vanilla, and salt until smooth.
  2. Gradually add powdered sugar and milk, adjusting to achieve a spreadable consistency.
Serving
  1. Once the cake has cooled, spread the icing over the top, slice, and serve.

Notes

Use room-temperature ingredients for best texture. For variations, consider espresso, orange zest, nuts, or a glaze instead of icing.
