These old-fashioned apple cider donuts are made with reduced apple cider and buttermilk, all rolled in delicious cinnamon sugar coating, Every bite of these cake donuts is a taste of fall!
Make the apple concentrate - peel and slice the apples. Add apple cider, apples, and a cinnamon stick to a small saucepan over medium heat. Cook down until there's a 1/2 cup of liquid left (I like to strain the apples from the concentrate to make sure it's exactly a 1/2 cup). Set aside and allow the mixture to cool completely. (It's helpful to drain the apples from the concentrate into a measuring cup to ensure that you have
Cream the butter and sugar: While the cider is cooling, add butter and brown sugar to a large bowl. Use an electric hand mixer and cream together for 3 minutes, then add vanilla extract and egg yolks. (The mixture may split a bit, this is OK)
Combine the dry ingredients: In a large bowl, whisk together flour, baking powder, kosher salt, cinnamon, ginger, nutmeg, and cloves.
Add apple butter and sour cream to the cooled apple cider concentrate. Whisk together until combined.
Add half of the flour mixture to the butter and sugar mixture. Use a flat spatula to fold the dry ingredients into the wet ingredients and mix until just combined. Then add all of the apple cider mixture and apples and mix until combined.
Add the remaining dry ingredients and fold together until a smooth and thick batter forms, about 20-30 seconds. Be sure not to overmix, stop as soon as all of the flour is fully incorporated.
Rest the dough: Cover with plastic wrap and place into the refrigerator for 2 hours, up to overnight.
Cut the dough: Add dough to a lightly floured work surface and roll out until 1/2 inch thickness. Use a donut cutter and cut 3-inch circles out of the dough, then punch out a smaller circle in the middle. Place onto a parchment-lined baking sheet and add to the refrigerator until the oil is at temp.
Heat the oil: Add vegetable oil to a large pan and heat to 350-370 degrees F.
Prep the sugar coating: Combine sugar, cinnamon, and cloves in a bowl.
Fry the donuts: Fry the donuts, about 2 at a time, for 2-3 minutes per side and place onto a paper towel-lined plate to drain excess grease.
Coat the donuts: Dip the donut into the cinnamon sugar mixture, ensuring both sides are coated. Repeat for the remaining dough.
