Oatmeal S’more Cookies

I can't count how many times I have made these cookies—they are our favorites. I love to bake all kinds of goodies with my two daughters, and my husband loves to sample the treats. —Carmen Rae, New Haven, Indiana

    They're okay. They are fun to try, but I wouldn't bring them as a dish for a public event. They're messy and difficult to get off of the pan after baking. They have a strange texture that isn't quite like an oatmeal cookie. I can definitely see how they would be better bar cookies than drop cookies. Overall, they're pretty good!

    The first time I made these I got the same messy ugly cookie others have written before. The second time I incorporated some of their ideas and came out with an outstanding bar cookie. I used 2 1/4 cups flour and 1 cup of whole oats. I sped it into a 9 x 11 pan and baked for 20 minutes at 350 degrees. Tasted as fabulous as the first time and even looked good. :-)

    It turned out great with a few minor adjustments....I left out 1/2 cup sugar, used 2 1/4 cup spelt & wheat flour, 1 cup quick oats (that's what I had on hand), added a few chocolate chips into the dough & then refrigerated it. Preheat oven to 375 degrees F once dough is cold. Drop dough on cookie sheets, press down, and top with marshmallows and chocolate chips. Bake for 10-12 min. or until golden brown.They stayed together great and taste great! They're waitin' for the kids to come home! :)

    The oats seemed to dry the dough out. The cookies were a mess. They taste OK. I have a half of a batch that I can present to friends and family.

    These are VERY good cookies, but VERY messy. They stick to the pan horribly even with grease on it. The taste is fantastic, but they definitely aren't pretty cookies as stated before. They turn into a bunch of pieces when taking them off the pan. Great idea... Trying to figure out how to make them better. I followed one reviews suggestion of 2 1/4 cups flour 1 cup oats.

    Started making this recipe last year, as listed, and they are my husbands favorite cookie. His work is constantly requesting that I make them. True, the marshmallows do melt and they may not be the prettiest cookies, but the taste is scrumptious! I may try a little less flour next time as recommended by another reader though.

    This recipe appeared in the magazine with 2 1/4 C flour, and 1 C oats, and it's much better that way. I recommend a silicone baking mat, so that the marshmallows don't stick to your cookie sheet. Definitely let them cool awhile before attempting to move them off of the mat!

    Am I the only one who had a problem with the marshmallows melting and spreading? Didn't look all that great - taste was fine

    Why do you have to add the eggs one at a time. I generally beat them up, then add them all at once. Can't see any difference in adding them one at a time.Connie
