• Prepare a bundt pan with cooking spray. Preheat oven to 325 degrees.
• It's optional to sprinkle nuts over bottom of greased bundt pan (either 10 or 12" pan works).
• Mix together cake mix, pudding mix, eggs, water, oil and rum.
• Bake for 1 hour.
• Remove from oven. Cool 10 minutes in pan.
• Invert onto serving plate and prick the top with a fork (so the glaze can run into the holes).
• To make the glaze, melt butter in saucepan. Stir in water and sugar. Boil 5 minutes, stirring constantly.
• Remove the pan from heat. Stir in the rum.
• Gently poke holes in the cake with a fork.

Make the glaze:

• Pour glaze evenly over top and sides of cake.
• Allow cake to absorb glaze. Keep doing this until glaze is used up.
• Cut into slices and serve warm with vanilla ice cream.
