Combine dry ingredients and set aside.
Combine wet ingredient and gradually add dry ingredients until just combined.

Lightly dip each doughnut in butter, followed by cinnamon and sugar mixture and serve warm.
Notes
Tips
Spray doughnut pan with non stick spray before adding the batter for easy removal.
The doughnuts will rise during baking, so fill the doughnut molds 3/4 of the way up or they could overflow.
The doughnuts are ready to come out of the oven when they are golden brown and an inserted toothpick comes out clean.
To Store
Refrigerate - Let the doughnuts cool completely and store them in an airtight container at room temperature up to 3 days with a paper towel to absorb excess moisture. Store refrigerated up to a week.
Freeze - You can also freeze doughnuts by wrapping them in plastic wrap or foil and placing them in a freezer bag. Thaw them at room temperature.
