Pancakes and waffles are great to have on hand for kids! You do not need to buy store waffles/eggos. Next time you make pancakes or waffles, make a double batch so that there leftovers. Simply let them cool and then lay them on a pan to freeze. Once frozen, transfer to a container. I reuse a cake tray I once bought (Birthday cake). Turn it upside down to turn it into a container rather than a tray!
Just pop them in the toaster and add your favourite topping!
