Preheat oven to 325°F. Line an 8x8x2-inch baking pan with foil. Grease the foil; set pan aside. Combine granola, oats, nuts, flour and raisins in a large mixing bowl. Stir together egg, brown sugar, oil, honey and cinnamon in a small bowl. Stir into granola mixture until well combined. Press evenly into the prepared pan.
Bake for 25 to 30 minutes or until lightly browned around the edges. Cool on a wire rack. Lift up on foil to remove from pan. Cut into bars.
To make ahead: Store bars in an airtight container at room temperature for up to 3 days.
Variation: For Energy Bars, prepare as above except substitute ¼ cup shelled sunflower seeds and ¼ cup chopped walnuts for the mixed nuts, substitute ¾ cup mixed dried fruit bits for the raisins, and substitute ground ginger for the ground cinnamon.
