McDonald’s (MCD) has sold over 60 million Shamrock Shakes since its inception nearly 50 years ago, though it was only launched nationally in 2012. The minty milkshake generally gets added to the menu each year in February and is removed again after St. Patrick’s Day. Other chains have attempted to emulate it, including Burger King with its new Oreo Irish Mint Shake, being offered until March 19, and Arby’s Mint Chocolate Swirl Shake, offered until the end of the month.

Speaking of Arby’s, it might be the only mainstream fast food chain that sells corned beef. So if you don’t have time to make a traditional corned beef and cabbage meal to celebrate St. Patrick’s Day, or if you just really like Arby’s, the sandwich chain offers a Reuben sandwich and corned beef and cheese sliders.

Lucky Charms

Because nothing will get you in the St. Patrick’s Day spirit like a bunch of kids trying to keep a cartoon leprechaun with a highly exaggerated Irish accent from eating his breakfast. Plus, we hear they’re magically delicious (though that might just be the 10 grams of sugar).

Select Krispy Kreme (KKD) locations, dubbed the “Lucky Ones,” will be serving up green doughnuts on St. Patrick’s Day. There are six variations dressed up for the day including a Shamrock doughnut, a green glazed doughnut, one with green sprinkles, and a St. Patrick’s Day Smiley.

Though some Girl Scout troops have already ended their cookie season, others are still going strong. That gives some of you extra time to buy Trefoil cookies shaped like a Shamrock to help you celebrate this St. Patrick’s Day.
