Mix together all ingredients in a stand mixture until well combined. Place batter in a piping bag and cut the end of the tip off. Squeeze batter into mini muffin tin, filling it half way. Bake at 400 degrees for 5-7 minutes. If serving right away frost as desired.

For the frosting you can either dust the tops of the mini donuts with powdered sugar or you can dip the tops of the donuts in melted butter and then immediately into the cinnamon and sugar mixture. I recommend frosting the donuts as you need them as the butter can make the donuts soggy after a few hours.
