This recipe has been in my family for as long as I can remember. My grandmother used to make this cake every year during rhubarb season.
1 1/2 cups brown sugar
1/2 cup butter
1 egg
1 teaspoon baking soda
1 cup buttermilk or sour milk

2 cup rhubarb, diced1 teaspoon vanilla

Then mix together
1/2 cup sugar
1 teaspoon cinnamon
and sprinkle on top of batter.
Bake at 350 degrees for 30 - 35 minutes.
Serve with fresh whipped cream.
