It’s Eat Ice Cream for Breakfast Day (I did not make this up). Eat Ice Cream for Breakfast Day was invented sometime in the 1960s in Rochester, NY (because everyone thinks of starting their day off with ice cream when it’s minus 142 degrees outside).
There are all sorts of ice cream flavors including lots of breakfast flavors (I’m not aware of a green eggs and ham one, although there very well could be such a thing).
There are the fruit flavors (orange, banana, strawberry), the coffee flavors (coffee, mocha), and the breakfast pastry flavors (donut, cinnamon roll).
There is bacon ice cream, and French toast ice cream, and most ice cream is made with an egg base.
There are waffle cones and cookie cones and don’t even get me started about the variety of add-ins that are really should be considered breakfast food.
The big question (duh) is WHO CARES IF IT’S PRETENDING TO BE BREAKFAST FOOD? It’s a holiday. Ice cream is being celebrated. What more rationale could you possibly want?
