"Made this today, followed someone's else's suggestion and used half a cup of flour also did not use the corn syrup. Worked beautiful. Thank you

Edit: second batch, used half a cup of flour and cut the cooking time to 12 mins. Made a lot of difference, the cookies are chewy insides and crispy outsides :-)"

"These cookies are excellent! The fact that these don't have any flour in them is a definite plus for those with wheat allergies. The only substitution I made was to use agave syrup instead of corn syrup due to a corn allergy. I used a medium scoop and baked them for 12 minutes with excellent results. Definitely a keeper!"
