Pumpkin S’mores Cake Bars Tips

*Do not forget to line your baking dish with parchment paper. These are very sticky bars and need the paper lining.

*Use a plastic knife to cut bars into squares. Such a great trick, plastic knife won’t stick to bars.

*Serve bars warm, room temperature and even chilled.

*Serve with a dollop of whipped cream if desired too.

*Store any leftovers in an airtight container in refrigerator.
