Other than buying them from the store with real-world cash, you get a donut every time you level up, you SOMETIMES get a donut for cleaning up nuclear waste when you buy new land, and there are some quests early on that grant donuts for adding friends to your roster. Also every week you get a mystery box, and there's a slim chance to get some donuts from that. And during special events, they sometimes pass them out.

To get a substantial amount of donuts, though, you'll have to fork over some cash (And if you're having fun, why not repay them with a buck or two?). I actually had really good luck with the lottery tickets, winning 100 donuts with my first, and another 50 with my second. That's 150 donuts for $2. Of course, your luck may vary.
