Is anyway that we store the donuts to keep them fresh longer?

Yes, you can freeze them! If you put your donuts in a freezer bag you can freeze them for up to a year. To reheat: Place frozen donuts on a cookie sheet in a 375 degree oven for 8-10 minutes. Sprinkle them with some more sugar and cinnamon and they are almost as good as new.
