This recipe is from the book Blueberry Muffin Murder by Joanne Fluke. I am posting it for safe keeping. Seems to me you can't go wrong with this recipe nor tire of it as you can make hundreds of combinations. You could even combine items listed in each catagory. It does not specify but I am guessing that you bake these in a 9"x11" pan sprayed with non-stick spray or lined with non-stick foil. Servings and yield is a guesstimate as it is not listed.
