Preheat oven to 400 F. Spray 8x8x2 inch baking pan; set aside. Separate biscuits; using fingers, flatten each into 3" circle. Brush each circle with an equal amount of the margarine, sprinkle each with 1/4 t brown sugar and an equal amount of cinnamon, then top each with 1T raisins. Roll each circle jelly-roll fashion and arrange in two rows, seam side down, in sprayed pan. Bake until rolls are puffed and golden brown, 8-12 minutes. Transfer pan to wire rack and lets rolls cool in pan.
In small bowl or cup combine remaining 2 1/2 t brown sugar and the powdered sugar, add water, 1 t at a time, stirring constantly until mixture is smooth and syrupy. Remove rolls to serving platter, brush each with an equal amount of sugar mixture. Makes 10 servings of 1 roll each.
