Chocolate Cavity Maker Cake

1 package chocolate cake mix
1 package instant chocolate pudding mix
1 16 ounce container sour cream
3 eggs
1 /3 cup vegetable oil
1 /2 cup coffee flavored liqueur (teacher had me use plain ol' coffee.)
2 cups semisweet chocolate chips
Preheat oven to 350 degrees
Grease and flour 10 inch Bundt pan (teacher had me use coco powder, so
 that if there was too much, it would just blend in with the cake.)
In a large bowl combine everything except chocolate chips.
Beat until ingredients are well blended.
Fold in 2 cups chocolate chips
Batter will be thick.
Spoon into prepared pan. (teacher had me use a measuring cup that had
 been greased inside and out instead.)
Bake 1 hour -cool 10 minutes in pan, then turnout and cool completely
 on wire rack.
Very rich, doesn't need frosting.
