Sunbeam donut maker
As for actual donut recipes they vary drastically. Some people prefer there donuts to be less sweet, or more sweet, bigger or smaller, or even thicker or thinner. These can all be found online and to your preference.
All of these donuts are possible to make if you purchase yourself your very own donut maker
Just like these pictured you can make your own select variety of donuts
I don't actually have a donut maker at home but would seriously consider it, epecially if you are as into the delightful pastries as myself. Like i said it isn't to hard and not that expensive at all to make your very own homemade donuts.
