Mark your calendars: This year, National Pancake Day will take place on Tuesday, March 1, 2011 from 7 a.m. – 10 p.m., and you can get a FREE short stack of pancakes!* In return for the free flapjacks, IHOP would ask you to consider leaving a little something behind for Children’s Miracle Network Hospitals and other designated local charities. Thanks to the diners” generosity, IHOP raised more than $2.1 million last year. IHOP began its National Pancake Day in 2006, and since then, has raised $5.35 million for Children’s Miracle Network Hospitals and other local charities and given away more than 10.1 million buttermilk pancakes. There’s a limit of one freebie per guest, and the offer is available dine-in only, while supplies last.
