Discontinued fast food items like the McSalad Shaker from McDonald's and the Cheesaritos from Taco Bell have achieved almost mythical status among fans. However, plenty of breakfast items have been discontinued, as well, and many of these (usually) delicious mistakes have faded from public memory.
Though breakfast is responsible for a surprisingly large portion of the fast food industry's total sales, people tend to focus on the lunch and dinner options at quick-serves. As a result, breakfast items tend to disappear off menus without much notice. You won't, for instance, see the Jack in the Box Waffle Breakfast Sandwich get the type of massive public campaign that brought back the McRib. However, while these discontinued breakfast items may be gone from your favorite fast food restaurant, they are not totally forgotten.
In 2016, McDonald's announced a miniature, kid-sized breakfast as part of its all-day breakfast menu. The Breakfast Happy Meal came with either an egg-and-cheese McMuffin or two McGriddles, along with a side of apples, hash browns, or yogurt.
Apparently, the Happy Meal Breakfasts were only a test item and McDonald's retired them when they didn't catch on.
Carl's Jr. tested out Blueberry Muffin Buns in a few select locations in 2016. The blueberry muffin tops replaced Carl's Jr.'s standard bun, and were used to bookend an egg, meat, and cheese breakfast sandwich.
As of 2019, they have not yet been made a permanent menu fixture.
In the summer of 2001, McDonald's introduced the Eggs Benedict McMuffin. Sandwiched between two toasted English muffins were eggs, Canadian bacon, American cheese, and Mickey D's special breakfast sauce. Alas, the Eggs Benedict McMuffin was only available for a limited time.
It was, believe it or not, a movie tie-in for Disney's Atlantis: The Lost Empire.
The Loaded Omelet Biscuit is still very much a thing at Hardee's/Carl's Jr. However, the double-loaded variety has gone the way of the dodo. Nestled between two "made-from-scratch" biscuits were two whole omelets made with bacon, ham, sausage, and three cheeses: Jack, cheddar, and American.
It was released in 2014, but later made a quiet exit without much fanfare.
