Creme filled doughnuts? Ok at room temp?
Per https://s3.amazonaws.com/kkd-e1-images.kktestkitchen.com/ecomm/nutrition/11329-nutrition.pdf, everything in the 'creme' (ugh I hate that word; it is a cream, crème is French) in a Krispy Kreme doughnut is shelf-stable. You're fine.

Also, you don't in general want to refrigerate bready/cakey/pastry-y products, unless you will be warming them before eating, due to how moisture and starch interact--you'll end up with a very dry-seeming product.
