Preheat oven to 375 degrees Fahrenheit.

Whisk the flour, sugar, baking soda, baking powder, cinnamon and salt in a large mixing bowl.

In a separate bowl, whisk together the wet ingredients (eggnog, egg and melted butter).

Pour the wet ingredients into the dry and fold together until just combined.

Once a dough has formed, place half of the dough on a generously floured surface.

Roll out until ½ inch thick.

Cut out donut shapes with a 3 inch round cookie cutter and a 1 inch round cookie cutter (the 1 inch in the center of the 3 inch circle cut out).

Place onto a baking sheet prepared with parchment paper.

Bake for 8- 12 minutes, flipping the donuts half way through baking.

Donuts will be golden brown when done cooking.

Repeat the process for cutting out and baking the remaining dough.

For the icing, add in all of the ingredients into a medium mixing bowl.

Whisk until well combined and is a thin consistency.

Once the donuts are cooled, dip the top half of the donut into the icing.

Place donut back onto the baking sheet.

If you would like to decorate with sprinkles, add them while the icing is still wet.

Allow icing to set.

Serve and enjoy!
