Chocolate Sheet Cake
recipe from Lisa @ The Cutting Edge of Ordinary - from a recipe in Taste of Home - Prize Winning Recipes 2009

1 cup butter, softened

2 cups sugar

4 eggs

2 teaspoons vanilla

2 ¼ cups cake flour

1 teaspoon baking soda

1 teaspoon salt

1 cup buttermilk

3 ounces bittersweet chocolate, melted



¼ cup baking cocoa

1/3 cup milk (bit more if needed)

½ cup butter, cubed

1 teaspoon vanilla

3 ½ cups confectioners’ sugar


In a large bowl cream the butter and sugar until light and fluffy. Add the eggs, one at a time, beating well after each addition. Beat in the vanilla.


Combine the flour, baking soda and salt and add it to the creamed mixture alternately with buttermilk, beating well after each addition. Stir in the chocolate until combined.


Pour into a greased 15in x10in x 1in baking pan. Bake at 350 for 23 – 27 minutes or until toothpick inserted into center comes out clean. Cool on a wire rack.


For frosting:

In a small saucepan bring the cocoa and milk to a boil over medium heat, stirring occasionally. Remove from the heat and stir in the butter and vanilla until the butter is melted. Whisk in the confectioners’ sugar until smooth. My frosting was a little too thick at this point so I just added in a bit more milk until it was the right consistency. Drizzle over cake and spread quickly. Let stand until set.
