The most important thing to keep these No-Yeast Cinnamon Rolls fresh for days is to NOT add the Greek Yogurt Icing over them until ready to be eaten. You can keep these rolls at room temperature, in an air-tight container for 2 days. Alternatively, you can also keep them in the fridge for up to 4 days. I recommend putting them in the microwave for 30 seconds before eating them to warm them up slightly. This will also make them softer and more moist!
