2 cups white sugar
1 3/4 cups all-purpose flour
3/4 cup unsweetened cocoa powder
1 1/2 teaspoons baking powder
1 1/2 teaspoons baking soda
1 teaspoon salt
2 eggs
1 cup milk
1/2 cup vegetable oil
2 teaspoons vanilla extract
1 cup boiling water
Directions
Preheat oven to 350 degrees F (175 degrees C). Grease and flour two nine inch round pans.
In a large bowl, stir together the sugar, flour, cocoa, baking powder, baking soda and salt. Add the eggs, milk, oil and vanilla, mix for 2 minutes on medium speed of mixer. Stir in the boiling water last. Batter will be thin. Pour evenly into the prepared pans.
