A few years ago my husband came up with the idea to make oatmeal peanut butter cookies with instant flavored oatmeal. Specifically the Maple Brown Sugar and/or the Cinnamon Roll flavors. But he just always threw things in without measuring and they turned out wonderful. I however, can not bake like that. So I am so happy to find this recipe! I subbed the instant flavored oatmeal for the quick oats (specifically a new kind that is out that is unsweetened which meant I didn't have to change the recipe called for sugar amounts, but I imagine that I would have to lessen the sugar amounts if the instant oatmeal where the presweetened kind). And they taste just like the ones my husband throws together (I also didn't have any margarine, so I used butter instead of the margarine and shortening, like others have said but I'm sure it would be fine with the other)
