You need to start early to cook breakfast in a solar oven and these cinnamon rolls were done middle of the morning. These were frozen cinnamon rolls from the grocery store. I set them out the evening before to thaw and rise. The sun was barely up when we put these out at 8:00 a.m. The temperature in the oven reached about 275 degrees. We took the rolls out at 11:00, but they were a little over cooked so they could definitely be taken out sooner. I glazed the top with the packaged glaze that came with the rolls.
