Blueberry Oat Bars
1 ½ c. uncooked rolled oats
¾ c. brown sugar
½ c. butter or margarine
¼ c. oil
1 ½ c. flour
½ t. soda
½ c. chopped nuts (optional; we use walnuts)
5 c. fresh or frozen blueberries
Mix the first 7 ingredients together until crumbly. Press ¾ of that mixture into a lightly greased 9x13 pan. Pour blueberries over the crust and sprinkle the remaining crust mixture over the top. Bake at 350°F for 25-30 minutes.
