DIRECTIONS

  • For the cake: Preheat the oven to 350 degrees F and lightly grease a 9x12 baking pan.
  • Mix all ingredients in a medium bowl until you can't see any more flour.
  • Pour into the prepared baking pan and bake for 30 minutes.
  • Let the cake cool completely in the pan on a wire rack.
  • For the frosting: Place powdered sugar and cocoa in a medium bowl (I usually use a 4-cup Pyrex mesuring cup).
  • Heat butter and milk in a small microwave-safe bowl in the microwave until the butter is melted (be careful - if the heat is too high, it'll splatter!).
  • Gradually beat the butter mixture into the cocoa mixture until smooth.
  • Stir in vanilla.
  • Spread the warm frosting over the cooled cake. The frosting makes about a cup or so.
