G Bakes!: From Helga's Kitchen: CRONUTS!...and Danish. Apparently cronuts are not a new thing. This woman's mother has had this recipe for years. I haven't tried it yet, so I can't guarantee the results, but doesn't it look delicious?!
Food52's cronut recipe --- again, with the eggs in the dough. I *do* wonder whether it would be possible to make these with an eggless pastry dough. Regardless, this is a good tutorial for how to roll out puff pastry or croissant dough.
