Combine all ingredients in large bowl and store in airtight container. For gift giving, place 4 cups of this mix in a decorative jar and attach the following instructions.
3/4 c. milk
1/3 c. oil
1/2 c. chopped nuts, if desired
1/2 c. raisins
2 c. oat bran muffin mix (this is in the ingredient list above)
Preheat oven to 400 degrees. Line 12 muffin cups with paper liners and set aside. Combine milk, oil, egg, and nuts and raisins in large bowl and mix well. Then stir in the muffin mix and stir just until dry ingredients are moistened; the batter will be lumpy. Spoon into prepared pan. Bake at 400 degrees for 13-15 minutes until muffins are golden brown. Remove from pan and cool on wire rack.
