Combine all ingredients (excluding topping ingredients) in a medium-sized bowl. Mix well and transfer the batter into a gallon size ziplock bag. Snip off one corner of the bag, and pipe the donut batter into the donut pan – filling each approximately 2/3 full.
Bake for 14-17 minutes or until donuts is springy to the touch.
While donuts are baking, prepare the topping. Melt the butter in a bowl large enough for dipping the donuts. In a separate bowl or plate, combine the cinnamon and sugar.
While the donuts are still hot, dip into the butter and then coat with the cinnamon and sugar mixture.
Donuts are best served fresh but are still quite enjoyable for 1-2 days if kept in an airtight container. Donuts can be frozen for up to 2 months. Simply place freshly baked donuts in freezer containers (skip the topping step!). When ready to eat, remove the desired number of donuts and microwave for 1-2 minutes. You can then add the topping if you wish.
