Preheat the oven to 325 degrees. Spray donut pan with cooking spray.
Combine flour, sugar, baking powder, cinnamon, nutmeg and salt in a large bowl. Add cider, milk, eggs, vanilla and melted butter. Mix until well blended.
Fill each donut cup about ¾ full (I use a pastry bag with the end snipped to do it neatly.) Bake for 10 minutes until donuts spring back when touched. Allow to cool slightly before removing from pan.
To make the cinnamon-sugar topping:
Mix together sugar, brown sugar and cinnamon in a shallow bowl until well combined. Brush each donut with melted butter then toss in cinnamon-sugar mixture until evenly coated.
Notes
STORAGE
These donuts are best fresh, but you can store them in an airtight container on the counter for up to 2 days.
These donuts can be frozen, but we recommend freezing prior to coating them in the cinnamon sugar.
