  1. In a large bowl, cream the shortening, brown sugar and 1/2 cup sugar until light and fluffy. Add egg and vanilla; beat for 2 minutes. Combine the flour, baking soda and salt; add to creamed mixture alternately with buttermilk, beating well after each addition. Stir in rhubarb.
  2. Pour into a greased 13-in. x 9-in. baking dish. Combine the cinnamon and remaining sugar; sprinkle over batter. Bake at 350° for 40-45 minutes or until a toothpick inserted near the center comes out clean. Serve warm; if desired, sprinkle with confectioners' sugar. Yield: 12-16 servings.
Editor's Note: If using frozen rhubarb, measure rhubarb while still frozen, then thaw completely. Drain in a colander, but do not press liquid out.

"I made this last night to bring to work with me today. My husband tried a piece of it and wouldn't let me bring it to work. He loved it so much. That's a huge compliment since he doesn't typically like sweets. This is a great recipe!"
