Not sure I know how much 11/2 of rolled oats is? Is the quantity 1 1/2 cups or 1/2 cup? I want to get the amounts right before I embark. :)

There are lots of reviews/comments on this bread. Read through them for clarification on quantities.
If no help there, use one of the original (and tested) maple oatmeal bread recipes at King Arthur Flour site.
