Cake batter:

Mix together

1 package yellow cake mix

1 package instant vanilla pudding

4 eggs

1/2 cup cold water

1/2 cup vegetable oil

1/2 cup dark rum

Pour this batter over the nuts.  Bake for one hour.

Cool.  Invert onto the serving plate.

Glaze:

In a saucepan, melt

1/4 pound butter

Stir in

1 cup sugar

1/4 cup water

Boil this mixture for five minutes, stirring constantly. 

Remove from heat, and stir in

Prick the top and sides of the cake with a toothpick or fork.  Spoon the glaze evenly over the cake, allowing it to absorb the glaze.
