Praline coated ring and apple doughnuts

Basically, after the praline icing I made for the carrot cake the other day, I wanted to try using ground praline instead of sugar for doughnuts.

The ring doughnuts on the left speak for themselves. The doughnuts on the right have a piece of cooked apple (hence their shape; I rolled them into circles and folded them over it, like a Cornish pasty) in them.
