Hard Cider: I used Angry Orchard Hard Cider (Crisp Apple flavor), but anything similar will work. Reducing the beer will increase the crisp apple flavor.
Spices: With the spices already in the hard cider beer, the addition of cinnamon, nutmeg, and a small amount of cardamom bring everything out!
Unsalted Butter: 10 TBS seems like a lot of butter, but it keeps the doughnut moist and rich. Unsalted is essential.
Salt: My go to kosher salt is always Diamond Crystal Kosher Salt. If using Mortons, cut back by ¼ tsp.
Baking Powder: This is your leavening agent. Make sure this is whisked thoroughly throughout the mixture.
Sugars: The combination of brown and white sugar gives a fantastic flavor and texture.
Flour: All-purpose works best. Substituting flours may throw off the ratios of other ingredients.
Eggs: Room temperature eggs will mix better.
Flavoring: Vanilla extract is a great addition to the flavors.
These were a hit!
