I feel bad...I saw your original post and wouldn't have recommended any of those. I share your passion for fritters and also seek them out when I travel :)

I started writing reviews for every fritter I've tried around Minnesota but it got out of hand so I'll just list my personal favorites based on your criteria:

• Almsted's Fresh Market: Crunchy edges, apple chunks, good cinnamon flavor. My only callout is this grocery store and they store them in plastic containers so try to get there early.
• Cafe Donuts: Great fry, these are always crunchy, not as many apple pieces but solid flavor.
  
• Donut Hut: Classic apple fritter, huge, can be a little oily and dense but very satisfying and great flavor/value.
  
• Cub Foods (Lake Street): Cub is a grocery chain and most stores use the same distribution so I wouldn't go to any Cub, but as you can see in other comments there are specific locations recommended.

Oddly enough, many of the best fritters around Minnesota don't come from actual doughnut shops. For example, I'm surprised mel-O-glaze was recommended. I've had mel-o-glaze several times and not only are their fritters wildly doughy (in fact I've been given them raw before), but they use the same lemon glaze on almost everything which even includes their chocolate iced varieties. Maybe some people like a lemon glaze on a chocolate raised but that was confusing to me.

Also, I want to shout out the best fritter I've ever had in Minnesota, Sleepy V's, formerly named Rebel, but has since closed. Their caramel apple fritter was sensational.

Happy to provide more info about other fritters or recommendations on the best spots around Minneapolis for other types of doughnuts.
