    My mother used to make a cookie similar to this back in the 1950s or 1960s.  I remember helping her make a shortbread crust which got baked, then melting butterscotch morsels over the crust and spreading this cornflake mixture over it.  Do you happen to have a recipe for this?  It was printed in the Sunday Parade magazine as I recall.  Thanks.

  2. They’re great when you throw them in the freezer once a harden up.

  3. 5 stars
    They are delicious, easy and so Awesone, thank you

  4. Hi! I have dark Karo syrup and honey in my pantry. Which one would you recommend as a replacement for the light syrup?? Thank you!  Can’t wait to make these!!

      Just in case anyone else is wondering this same question…I only had dark corn syrup as well and they came out just as good as when I’ve used light corn syrup!

  5. 5 stars
    Super easy, and super good! A little too good, perhaps… I can’t seem to stop eating them. I had to put them up in the cabinet so they wouldn’t tempt me every time I walked in the kitchen.

    1. Rachel, I totally know what you mean! These bad boys are GOOD! Glad you loved them and thanks so much for leaving a review. :)
