I got this recipe from DD's best friend (she's like a daughter to me) that has Chron's Disease -- with her permission;-D
Adrienne's Coffee Cake
1/2 cup vegetable shortening
1 cup sugar
2 eggs
1 cup flour
2 tsp baking powder
1/4 tsp. salt
1 cup soy sour cream
1 tsp vanilla
1/2 cup brown sugar
1 tbs vegetable shortening

2 tsp cinnamon
In an electric mixer, cream the vegetable shortening and the sugar until thoroughly combined. Add the eggs and vanilla. Sift the dry ingredients together. Alternately add the dry ingredients and the soy sour cream to the batter. Stir until combined.
Preheat the oven to 350 degrees. In a small mixing bowl, combine the brown sugar, 1 tbs vegetable shortening and cinnamon with a fork. Spray a circular tube or bundt pan with non-stick cooking spray.
Pour the batter into the pan. Sprinkle the brown sugar topping on the surface of the batter. Run a knife through the batter to slightly incorporate the brown sugar mixture. Bake the coffee cake for 50-55 minutes. Let stand for 10 minutes before inverting on to a serving plate. Dust with powdered sugar and serve warm. Serves 6-8.
