Pistachio Bread

I got this recipe from my sister-in-law, Denise, years ago and I typically only make it on St. Patricks Day because it's so good you can't stop eating it! It is a yummy, moist bread. Ingredients:
1 box white cake mix
1/2 cup water
1/2 cup oil
2 small boxes pistachio pudding
3 eggs
1 cup sour cream


Mix ingredients together. Place 1/3 of the batter on the bottom of 2 greased loaf pans. Sprinkle with a cinnamon sugar mixture, then put on the remaining batter and sprinkle the top with more cinnamon and sugar. Bake at 350 for 55 minutes.
