In our current age of wild, over-the-top doughnuts laden with toppings, there's something to be said for a doughnut shop that keeps it simple. At Dutch Donut Factory in east Mesa, some of the doughnuts have sprinkles. That's about it as far as bells and whistles go, but when the basic element is this good, you don't have to slap a bunch of stuff on it. All the classic varieties of doughnuts are represented here — plain, glazed, frosted — as well as other mainstays like cinnamon rolls, bear claws and apple fritters. They're excellent warm if you get there in early in the morning or later in the day, with just the right texture and sweetness.
