Preheat oven to 400˚F. Spray 12-cup muffin pan (2-1/2 x 1-1/4 inch cups) with cooking spray or line with paper baking cups.
Combine flour, oats, bran, brown sugar, baking powder, cinnamon and salt in a large mixing bowl. Whisk together milk, oil, corn syrup and eggs in a separate bowl. Add to flour mixture and stir just until flour is moistened.
Divide batter evenly into prepared muffin cups.
Bake 15 to 18 minutes or until a deep golden brown and toothpick inserted in center comes out clean. Transfer muffins to a wire rack to cool. Serve warm or store in air tight container.
Recipe Tip: To garnish, sprinkle tops of muffin batter with additional rolled oats and brown sugar prior to baking. Try adding 1/2 cup nuts or raisins for variety.
