If you're a fan of McDonald's McGriddle sandwich, you'll soon be able to satiate your cravings whenever you want.

The fast food chain will add McGriddle sandwiches -- which consist of fried bacon, egg and American cheese served on a small pancake with maple flavoring -- to its all-day menu starting September 21, Business Insider reported. It will also make McMuffin and biscuit sandwiches available at all restaurants all day.

Previously, McDonald's restaurants served either McMuffin sandwiches or biscuit sandwiches, causing some fast food aficionados to complain when the menu was first unveiled last fall.

McDonald's began testing the McGriddle on the all-day breakfast menu in selected locations in February. Apparently, the test was successful: In July, the chain announced that it would include the McGriddle on the all-day breakfast menu nationwide -- and as well as give customers the choice between McMuffin or biscuit sandwiches.

The all-day breakfast menu has caused Mickey D's sales to skyrocket. In order to keep customers coming through the door, the chain has experimented with other fast food gimmicks, like all-you-can-eat fries and a super-sized Big Mac called a Grand Mac.

The all-day breakfast menu will now include: egg McMuffins; sausage McMuffins with egg; sausage McMuffins; bacon, egg, and cheese biscuits; sausage biscuits with egg; sausage biscuits; sausage biscuits, bacon, egg, and cheese McGriddles; sausage, egg, and cheese McGriddles; sausage McGriddles; Hotcakes; Hotcakes and sausage, sausage burritos; fruit and maple oatmeal, fruit and yogurt parfait; and in some restaurants, hash browns.
