In honor of National Pancake Day, The International House of Pancakes (IHOP) is inviting diners to enjoy a free short stack of buttermilk pancakes. The restaurant chain started this promotion in 2006 as a way to raise money for various charities including the Children's Miracle Network Hospitals. IHOP is asking diners to leave a donation when visiting the restaurant. If you cannot make it out to IHOP to receive your complimentary short stack, try making these lemon blueberry pancakes at home. The recipe is super easy and these delicious pancakes are great any time of the day.
