Preheat oven to 350'F. Mix the first 8 ingredients together; pour into an ungreased 13" x 9" baking pan. Sprinkle cake mix over the top; drizzle with margarine. Bake for 25 minutes. Top with nuts and bake for an additional 15 minutes. Makes 15 to 18 servings.
My modifications:
I replaced the Ginger and Cinnamon with 2 teaspoons of Pumkin Pie Spice and the Margarine with Unsalted Butter. Left off the nuts and baked it in a 8" x 11" pan and extended the baking time to 50 minutes total.
