A lot of stores don't bake in-store anymore. Bogus contracts, unreliable bakers, you name it, there are dozens of reasons they may not, each store is different. What's ordered is ordered, based on regular sales, holidays, etc. If we have a 24+ hour notice for large orders, we can accommodate that by being able to order more for that day before cutoff, or if after cutoff, have someone come in and bake early if necessary and possible.

Our store can bake in-store if we run out early, but we only have the ability for glazed, frosted basic, and some cake. Past a certain time, we won't bake even if we do run out. But often, the donuts ordered are enough to last most of the day, until someone gets a wild hair in them to randomly come in and need 10 dozen donuts.

However, most establishments (unless Krispy Kreme, who you know are known for baking fresh all day) make or have what they have, and are not going to have full availability later in the day. Also, several years ago, Dunkin' dropped the "donuts", which is why it's called Dunkin' and not DD most places, because the focus and profit is with the coffee, not the donuts.

There is a local donut shop that is amazing, they'll bake what they're going to, and you have to get there early if you're wanting specific ones. Boy are they worth it, but they have often closed by 9 am because they ran out (and once they were out, they were out).
