This is a fast and easy sheet cake that comes out perfect every time.  While I was living in Dallas, this cake was an absolute must have for every potluck.  By the way, a potluck in Texas is called a spread. A potluck or spread is a food party where everyone brings a dish to share.

TEXAS SHEET CAKE

1 (18.25 oz.) box chocolate cake mix, 1 (3.9 oz.) box instant chocolate pudding mix, 3/4 cup butter,  melted, 3/4 cup milk, ½ teaspoon vanilla, 4 eggs, 1 cup sour cream, 1 (12 oz.) can chocolate icing,  1 1/2 cups chopped pecans.

Mix all the ingredients in a bowl.  Mix well pour into a greased and floured 9 x 13-inch sheet pan.  Bake at 350 degrees for 45 to 50 minutes. Insert a case knife into the center of the cake, if the knife comes out clean the cake is done.  Remove from the stove and allow to cool. Get a can of prepared chocolate cake frosting.  Spread a thin layer on top of the cooled cake then sprinkle the chopped pecans on top.
