If you plan to have extra knots I recommend leaving off the icing until ready to enjoy.u003cbr/u003eu003cbr/u003eMy person favorite way to reheat a cinnamon twist is in the oven. 350° for only about 5-8 minutes is enough to soften the cinnamon rolls. You can also briefly reheat them in a microwave for about 10 seconds at a time at 50% power.
