I have eaten a Cinnabon a couple of times but never knew how many calories they were. They are addicting. It's hard to walk by their stand and not buy one. It's probably the most fattening pastry you can eat at 880 calories. American travels trying to get home for the holidays will be fueling up on Cinnabons, it seems. Cinnabon has revealed that it expects to sell nearly one million rolls between Wednesday and Sunday - that's a whopping 8,300 rolls every hour, and 175million calories per day. 'Some people wait all year to indulge,' Deborah Rowley, Cinnabon’s vice president of new market operations, told Bloomberg Businessweek of the 880-calorie cinnamon roll. According to Ms Rowley, Cinnabon sales increase about 50per cent from Thanksgiving until January 2nd, with Las Vegas airport being the biggest Cinnabon seller. Cinnabon, which was founded in Seattle in 1985, now operates more than 770 locations worldwide, and according to Google, even searches for the sweet treat increase during the holiday period. Christmas Eve, however, is Cinnabon's busiest day of the year with some stores receiving 500 pre-orders that day.
