Of all the deserts that my Nana Rita use to make these were always at the top of my list right under her chocolate coconut No Bake Cookies. I don't know much about their history other than the fact that they share a name with a somewhat similar candy bars.
O'Henry Bars are chocolate-y, peanut butter-y, oatmeal-y, chewy, and crunchy. Also very easily converted to gluten-free. The only substitution necessary to turn them safe is gluten-free oats. Also a gluten-free peanut butter, so be careful to avoid double dipped crumbs!
My recipe box is currently at home in Weymouth and I am at school in Boston so the actual recipe will be coming shortly! Stay tuned!
