AMISH RHUBARB CAKE

1 1/2 cups brown sugar
2 cups flour
1/2 cup shortening
1 cup buttermilk
1 egg
1/2 tsp baking soda
1 1/2 cups fresh rhubarb
1/2 tsp salt

Preheat oven to 350 degrees. Grease a 9 x 13-inch baking pan; set aside.

Combine shortening, brown sugar, and egg; beat until light and fluffy. Combine the flour, baking soda and salt together; add to the egg mixture alternately with the buttermilk, ending with flour. Fold in the rhubarb and mix in well. Pour mixture into the prepared pan and bake at 350 degrees for 30 to 40 minutes until a wooden toothpick inserted in the center comes out clean. Cool before cutting. Serve with whipped cream, if desired.
