  1. Preheat oven to 350°. In a small bowl, combine rhubarb and 1/4 cup sugar. In a large bowl, cream butter and remaining sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Stir in vanilla. In another bowl, whisk flour, baking powder, salt and baking soda; add to creamed mixture alternately with buttermilk, beating well after each addition. Fold in rhubarb mixture.
  2. Pour into a greased 9-in. square baking pan. In a small bowl, mix brown sugar and cinnamon; sprinkle over batter. Bake 25-30 minutes or until a toothpick inserted near the center comes out clean. Serve warm or at room temperature. Yield: 9 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 2 times and found that I had to bake much longer then 30min, more like 45 min. I has been a hit at my house, and a scoop of vanilla ice cream really hits the spot!"

"I already made it twice--1st time it looked done but it was still very solid--not cake like. Thought it was old baking powder, so made it again on Fri.-same thing. Baked it according to directions & toothpick came out clean. Not sure I want to try it again & bake it alot longer or what. Any suggestions?"
