Rhubarb Walnut Muffins

Rhubarb season is winding down but I had enough to make these tasty muffins today. What a treat!

1 1/2 cups flour
3/4 cup brown sugar
1/2 tsp. baking soda
1/2 tsp. salt
1/3 cup vegetable oil
1 egg
1/2 cup buttermilk
1 tsp. vanilla
1 cup chopped rhubarb
1/2 cup chopped walnuts

Combine dry ingredients. In another bowl, thoroughly mix wet ingredients. Add wet ingredients to dry ingredients mixing only until moistened. Fold in rhubarb and walnuts. Spoon into greased muffin tin.

Combine 1/2 cup brown sugar, 1/4 cup chopped walnuts and 1 tsp. cinnamon for topping. Sprinkle over muffins. Bake for 20-25 minutes at 325 degrees. Makes 12 muffins.
