Of course they do. Jelly donuts would be very messy with a large hole in the middle of it.
Here in Canada besides the regular doughnut with the hole in the center and the jelly filled/sugar coated treat we have what is called a fritter. These are approximately hand sized irregular shaped, fried cakes with various fruits like apples or blueberries blended into the dough and lightly glazed. These are very popular with a large double double coffee at the local Tim Horton's.
Why do doughnuts have holes? The question as to why doughnuts have holes has been raised by dozens of bakers over the years, but most agree that the answer to this sticky question lies in the fact that the interior of these fried cakes would not cook fully without a hole in the center. In short, the consistency of a doughnut lacking a hole would be, quite simply, doughy.
Another riveting theory as to the origin of the bulls eye in the doughnut holds that a sea captain named Hanson Gregory, while manning his post one stormy night, found it impossible both to steer his vessel and to eat his fried cake. Out of sheer frustration, and probably out of hunger, he impaled his cake over one of the spokes of the ship's wheel, thereby creating a finger hold with which to grip the cake. Quite pleased with his ingenuity, Mr. Gregory ordered the galley's cook to fry the cakes in that manner henceforth.
The hole is poked out of the donut before it is fried. So usually that bit of batter returns to the bowl and incorporated with the rest of the batter to make more donuts. In some cases the "holes" are fried up into little round ball-shaped donuts called "donut holes."
It's the evolution of the donut, the first donuts don't have holes, but its pioneers realized that if they do put a hole in the donut, it would cook faster and more evenly...
The hole helps doughnuts to bake evenly.
The hole in the doughnut was introduced to allow more even frying.
They don't have holes
The Donut Hole was created in 1968.

The advantage depends on how the plan pays through the donut hole. Most plans that give you coverage through the gap pay for generics only, and not brand names. This can also depend on whether you hit the donut hole or not. If you not subject to hit the gap, then you may be paying for a plan that you don't need. If indeed you know your going to hit the gap, then it would be to your advantage to take the plan that gives you the donut hole coverage. In 2009, the donut hole begins $2700.00 and ends at $4350.00
the donut hole sometimes put back in dough sometimes baked and sold
