McDonald's all-day breakfast fans will have yet another combination of sausage, egg and cheese to salivate over come September.

The McGriddle — a breakfast sandwich made with maple-flavored griddle cakes — will be added to the all-day service this fall, along with McMuffins and biscuit sandwiches.

Most restaurants already serve either McMuffins or biscuit sandwiches all day. Now the fast food chain is simplifying its offering by switching to one national menu that will include all three types of sandwiches.

The expansion comes by customer demand — McGriddles are the most requested item not already offered nationally, says McDonald's spokeswoman Melissa Layton.

McDonald's all-day breakfast has been a huge hit since launching last year and has helped bump up sales for the struggling chain. Most recently, the company reported same-store sales increased 5.4% in the U.S. due to the popularity of all-day breakfast and the McPick 2 menu.
