The key to ensuring your cookies slide right off your baking tray once your caramels have gone all gooey during baking is to make sure the caramel’s are placed as near to the top and center of your dough as possible. If one struggles to come off the tray once you've allowed the cookies to cool on the tray for 5 minutes, give it a little longer before removing as the caramel will set in the cookie as it cools. The dough will be a little sticky due to the oatmeal so do be aware this will be a little messy.
