Did this exactly as stated because I was thrilled to be able to use up some oatmeal packets I had hanging around. However, the cookies turned out flatter than pancakes! The taste was good, but I had to literally put them in the freezer on the pan and then peel them off the parchment paper. My husband ate them rolled up like crepes! Don't know what happened, and I'm sorry to give a low star review, but this really did not work for me.
I increased the amount of baking powder and soda hoping that it would prevent the cookies from turning out flatter than pancakes like the other reviewer's did, worked out perfectly.
I'm not a fan of oatmeal cookies but these are good.
