Today is National Pancake Day. And that means IHOP is offering a free short-stack of their signature buttermilk pancakes today from 7 a.m. to 10 p.m.

In return, diners are asked to leave a voluntary donation to support the Children’s Miracle Network Hospitals program at Johns Hopkins Children’s Center. Most of the money raised goes to fundraising events for non-profits. 

IHOP’s goal is to raise $3 million this year.
