"Ooey Gooey Butter Cake

1 yellow cake mix
1/2 stick butter -a little more than that works great!
3 eggs
8 oz pkg cream cheese
1 lb powdered sugar
1 tsp vanilla

Mix until crumbly, the cake mix, butter, and 1 egg.
Press into an oblong pan as a crust.  Set aside.  In a
bowl combine cream cheese, powdered sugar, and two
eggs and beat until well blened (smooth).  Add
vanilla.  Pour over crust in oblong pan.  Bake at 350
for about 30 minutes or until the top gets lightly
brown.
