I once worked at a donut store. Left me with a lifelong dislike of the odor of frygrease. I also saw what eating donuts every day did to my customers over time. At the time, I did sometimes eat the fresh donuts, and that kinda spoiled me, since cold donuts don't taste nearly as good.
As many times as I have been to WDW, I've not tried any of the foods listed, except the beignets when they were sold at a different location at POFQ.
The best desserts I've had at WDW were the special Princess ones they had for a short time. One was a Rapunzel ice cream cone that was excellent. Pretty and tasty.
Otherwise for desserts, I like the offerings at Amorette's. Just about everything we have tried there, we enjoyed. A recent one was some excellent chocolate covered strawberries. (Very flavorful strawberries, pretty chocolate heart design). The rose tart was also pretty good.
If you will be at Epcot during the Art Festival, we also had a few delicious sweets last year. One was a deconstructed dessert from the deconstructed booth. I'm normally not that big on the deconstructed trend, but all the parts of that dessert were delicious. Looks like they have a key lime pie this year.
