  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour

  • 1/2 teaspoon salt
  • 1 cup heavy cream

Directions

  1. Preheat the oven to 350°F (175°C). Grease a 9×13 inch baking pan.
  2. In a saucepan, melt the butter over medium heat. Stir in sugar, and remove from heat. Let cool slightly, then beat in eggs and vanilla.
  3. In a bowl, whisk together flour, cocoa powder, and salt. Gradually stir into the egg mixture until just combined.
