This recipe is from here. Tailor these to fit your family's taste using raisins, dried fruit, nuts, peanuts, chocolate chips, coconut, etc. My kids love them with mini chocolate chips. I prefer to omit the cinnamon if I'm doing a chocolate batch.
4 c. dry oats (I used old-fashioned but you can use quick)
1 1/2 c. flour (I used 1/2 cup whole wheat flour, 1 cup all-purpose)
1 c. brown sugar
1/2 c. sugar
1 t. cinnamon (optional)
1/2 t. salt
3/4 c. oil (I used 1/2 c. applesauce and 1/4 c. oil)
1 1/2 c. raisins, dried cranberries, dried fruit, nuts and/or chocolate chips
Mix together all ingredients until just combined. Press into a greased 13×9 casserole dish and bake at 350 degrees for 25-30 minutes. Let cool completely before cutting into individual bars.
