HERSHEY'S COCOA DEEP DARK CHOCOLATE CAKE
2 cups sugar
1-3/4 cups flour
3/4 cup cocoa powder
1-1/2 teaspoons baking soda
1-1/2 teaspoons baking powder
1 teaspoon salt
2 eggs
1 cup milk
1/2 cup vegetable oil
2 teaspoons vanilla
1 cup boiling water
Heat oven to 350 degrees. Grease and flour (I spray the pans with Pam spray and then cut parchment paper rounds and put them in the bottom of each round pan and spray it lightly again so it doesn't stick to the bottom) 2 round pans 9 x 1-1/2 inches, or 3 eight inch pans, or a rectangle 13 x 9 inch pan. In a large mixer bowl combine dry ingredients. Add eggs, milk, oil and vanilla. Beat on medium speed 2 minutes. Remove from mixer. Stir in boiling water (batter will be thin). Pour into prepared pans (not over half full on the 8 inch pans so when it rises it stays in the pans) and bake 30-35 minutes for round pans, 35-40 minutes for rectangular pan, or until a tooth pick inserted in the center comes out clean. Cool cake in rounds for 10 minutes; remove from pans sliding knife around the outside perimeter first. Do not remove cake if baked in rectangular pan. Frost with one-bowl buttercream frosting or frosting of your choice.
