Ingredients (Doughnut Batter):

1 1/2 cups (360ml) apple cider2 1/2 cups (354g/12½ oz) all-purpose flour1 teaspoon baking soda3/4 teaspoon baking powder1 1/2 teaspoon ground cinnamon1/4 teaspoon ground nutmeg1/8 teaspoon ground cardamom1/4 teaspoon salt

2 Tablespoons (28g) unsalted butter, melted1 large egg1/2 cup (100g) packed light or dark brown sugar1/2 cup (100g) granulated sugar1/2 cup (120ml) milk1 teaspoon pure vanilla extractIngredients (Topping):6 Tablespoons unsalted butter, melted1/3 cup granulated sugar1 teaspoon ground cinnamon1 pinch saltInstructionsPreheat oven to 350f. Grease doughnut baking molds with oil or butter (should have enough to make 12-14 doughnuts)Reduce the apple cider: simmer cider in a small saucepan, stirring occasionally, until it's reduced to 1/2 cup; about 20-30 minutes. Skim spices or particles or run through a fine-mesh strainer. when in doubt, it's better to over-reduce than under, as long as it's not burned; just add more cider to make up the difference.Combine dry ingredients: while cider is simmering, combine flour, baking soda, baking powder, cinnamon, nutmeg, cardamom, and salt in a bowl; set aside.Combine wet ingredients: combine butter, egg, brown sugar, granulated sugar, milk, and vanilla in another bowl.Mix batter: add reduced cider to wet ingredients; then mix in dry ingredients a bit at a time. Batter should be somewhat thick, but not a dough.Spoon batter into greased doughnut molds. It should make 12 doughnuts, possibly with a little extra. (Leftover batter can be used to create cookie-like "doughnut holes" on a baking sheet.)Bake at 350f for about 10-12 minutes, until cooked through. While baking, mix together dry ingredients for topping in a small bowl; melt 6 tbsp butter in another bowl.Remove doughnuts from molds immediately after baking. As soon as they are cool enough to handle, dip them first into butter, then into dry topping mix. Don't over-coat doughnuts; one dip is enough.
