McDonald’s is celebrating National Cheeseburger Day this year on Monday, September 18 with double the goodness! For one day only, fans can snag a Double Cheeseburger for only $0.50from any participating location nationwide when they order exclusively through the McDonald’s App*. 

The extra-cheesy and delicious holiday comes as our chefs have been cooking up small but tasty improvements to our classic burgers – including the Double Cheeseburger. Announced earlier this year, these are McDonald’s hottest, juiciest and tastiest burgers yet.

The magic is in the details: 

  • Softer, pillowy buns that are freshly toasted to a golden brown  
  • Perfectly melted cheese that will make you want to savor every last bit off the wrapper   
  • Juicier, caramelized flavor from adding white onions to the patties while they’re still on the grill   
  • Even more of everyone’s favorite Big Mac sauce, bringing more tangy sweetness in every Big Mac bite  

As always, customers can customize their orders to match their personal taste preferences, including asking for no onions or pickles, or holding the sauce on their favorite burger.  

The McDonald’s app is available for download in the Apple App Store and the Android Google Play Store. With the McDonald’s app, customers get access to exclusive deals, they can order ahead and pass the line with Mobile Order & Pay, plus they can join MyMcDonald’s Rewards to earn points on every order to redeem for free McDonald’s.
