Remember when they had the commercials "I gotta make the donuts!!" where they made donuts throughout the day and night. Now they "dumbed it down" for better consistency between stores where they make them at a central location and truck them as "blanks" to the stores. The stores then finish them based on their needs, adding the fillings (jellies and creams) and toppings (different frostings or sugars). So that the size and density of the donuts are the same every store you go to. In South Florida, most stores get the trucks once a day in the morning, with the higher volume locations getting a second delivery in the late morning.

Stores are now smaller or combined with Baskin's-Robbins Ice Cream to better maximize revenue per location. I have stopped eating doughnuts at night except for my local Krispy Kreme who makes them all day and night as they are the local "factory" for those sold in grocery stores and Walmart locations throughout South Florida.
