Bring apple cider to a boil on a medium saucepan on medium heat. Lower heat to a simmer for about 15 minutes, until liquid has been reduced to 1/3 cup. Remove the apple cider syrup from heat and cool completely.
240 grams apple cider | unfiltered apple juice
Cinnamon Sugar Coating
Prepare the topping to set aside. Stir the granulated sugar, and cinnamon together in a shallow medium bowl. Save for coating warm donuts.
Preheat oven to 350℉ (180℃) and prepare two, 6-capacity donut pans with a light coating of baking spray. If you only have one donut pan, bake 6 donuts, wash the pan and bake the rest.
Whisk together the flour, baking powder, baking soda, spices and salt together in a medium bowl. Set aside
250 grams all purpose flour, 1 teaspoon baking powder, 1 teaspoon baking soda, 1 teaspoon ground cinnamon, 1/2 teaspoon ground ginger, 1/2 teaspoon fine sea salt
Place the brown sugar, granulated sugar, oil, applesauce, creme fraiche, egg, and vanilla in a large bowl, then hand whisk to combine. Stir in the reduced apple cider until distributed evenly.
Add half of the flour mixture to the wet mixture and slowly whisk to combine. Repeat with the second half of the dry mixture. The batter will be slightly thick.
Transfer the batter to a piping bag or use a spoon to fill each donut cavity about 2/3-3/4 full.
Place the donut trays on the middle rack of the oven. Bake for 9-11 minutes until the tops spring back with a gently press of your finger tip. Or a toothpick inserted into the donut comes out clean.
Place trays on wire cooling rack for about 2 minutes. Then, invert pans to release the warm donuts directly onto cooling rack.
Coat Donuts
Gently brush a thin layer of melted butter with a pastry brush onto the donuts before carefully rolling them in the bowl of cinnamon sugar.
