I questioned the name, because one recipe I found said "Oh Henry" (as in "Oh, Henry, these bars are just wonderful!") and others said "O Henry" (as in the writer?). You also may remember the "Oh Henry!" candy bar, which had chocolate, peanuts, caramel, and fudge - and doesn't seem to resemble this recipe. I quick Google search shed no light on the name and actually caused more confusion. My advice? Eat, don't question. Enjoy!
