Giant Cakie

1 cake mix, any flavor

1 stick butter

1 ½ cups chocolate chips

2 eggs

1 teaspoon vanilla

Heat oven to 350 degrees. Grease a pizza pan; set aside. With electric mixer, combine cake mix, eggs, butter and vanilla. At first, this looks like it will never be any kind of batter, but it will come together like cookie dough. Stir in chips by hand. Press dough in pan; bake 25 minutes.
