Start by reducing the apple cider in a small saucepan on the stove. To do this, bring apple cider to a boil, then reduce to a simmer, stirring occasionally for about 15 minutes. Once reduced to about ½ cup, remove from heat and let cool.

In a large bowl, whisk together flour, sugar, baking powder, baking soda, cinnamon, salt, and nutmeg. Pour in reduced apple cider, melted vegan butter, and dairy-free milk. Stir to combine, being careful not to over mix! If the batter seems too dry, add extra dairy-free milk in one tablespoon at a time.

Pipe the batter into a prepared donut pan, filling about ¾ of the way full. Bake at 350F for about 10 minutes. Flip baked donuts onto a cooling rack and let cool completely!

To make cinnamon sugar coating, melt vegan butter. In a small bowl, whisk together sugar and cinnamon. Brush the tops of each donut with melted butter and dip into the cinnamon sugar.
