1 box yellow cake mix
1 pkg. instant pistachio pudding
1 sm. pkg. Dream Whip
1 c. Club Soda
1 c. oil
4 eggs
1 c. chopped nuts
1/2 c. chocolate syrup

Mix together in a large bowl: cake mix, pudding mix and Dream Whip. Beat eggs, oil and Club Soda; add to dry ingredients. Reserve 1 cup of the batter. Pour remaining batter into a Bundt pan. Add chopped nuts and chocolate syrup to the reserved batter. Swirl this mixture into the batter in the Bundt pan (marbelize). Bake at 325 degrees for 60 minutes. Expensive but good!
