Notes
Tips
Don’t overmix the donut batter, the ingredients should be just combined. Over mixing can cause them to become chewy rather than light and fluffy.
Don’t overfill your donut pan – Fill 3/4 full to allow for rise.
These cinnamon sugar donuts are ready to come out of the oven when they are golden brown and an inserted toothpick comes out clean.
If you are making them ahead of time, they can be reheated in the microwave or oven before serving.
