The trick is to take it slow with heat and be gentle when you mix so your bars stay chewy and awesome.

Best Ways to Enjoy

Tastes amazing a little warm with a cold glass of milk. Toss one in a lunch bag for fun. Or serve with a mix of other cereal bars for dessert trays.

Fun Twists

Pour some white chocolate on top if you want to make them rich. Add a shake of extra cinnamon for serious spice fans. Try colored sprinkles to make them festive for holidays.

Storage Made Easy

Keep them sealed up and they'll last a few days at room temp. Cool them in the fridge and they’ll last about a week. Freeze each one by itself and you've got treats for up to two months.
