Preheat oven to 350 °F. Lightly grease a 9X9-inch square baking pan. In a medium-size saucepan, combine honey, brown sugar, oil, and cinnamon, and bring to a boil. Continue boiling for 2 minutes; do not stir. In a large mixing bowl, combine Oats and blueberries. Stir in honey mixture until thoroughly blended. Spread onto the prepared baking pan, gently pressing mixture flat. Bake until lightly browned, about 40 minutes. Cool completely in the pan on a wire rack. Cut into 1-1/2 by 3 inch bars. Makes 18 bars.
