Preheat oven to 350° F. Grease two donut pans (see note) and set aside.
In a small bowl, combine the dry ingredients and set aside.
2 cups all-purpose flour, 1 ½ teaspoons baking powder, 1 teaspoon cinnamon, ½ teaspoon salt
In a large bowl, whisk together vegetable oil, eggs, sugar, applesauce, boiled cider (see note), and vanilla until combined.
⅓ cup vegetable oil, 3 eggs, at room temperature, 1¼ cup granulated sugar, 1 cup unsweetened applesauce, ¼ cup boiled cider, 1 ½ teaspoons vanilla extract
Add dry ingredients to the wet ingredients. Mix just until combined. Spoon or pipe the batter into the prepared pans (see note).
Bake 13-15 minutes, or until a toothpick inserted in the center of the donut comes out clean. (Mini donuts will bake in 8-10 minutes.)
Allow doughnuts to cool slightly. While they're cooling, combine sugar and cinnamon in a plastic or paper bag.
3 Tablespoons granulated sugar, ½ teaspoon ground cinnamon
Once the donuts are cool enough to be handled and not fall apart, coat the donuts in the cinnamon-sugar coating by shaking the donuts (1-2 at at a time) in the bag. Place the coated donuts on a wire rack to cool completely.
For Glaze
In a small bowl, combine all glaze ingredients. If you don't have boiled cider, you can add a smaller amount of apple cider or apple juice. Dip donuts in the glaze. Allow glaze to set before serving.Enjoy!
Note on boiled cider: I buy pre-bottled boiled cider from King Arthur Flour (link [here]). I enjoy the flavor and it's convenient to have on-hand. It also keeps in the refrigerator for a long time! If you prefer not to buy boiled cider, you could boil cider in a small saucepan down to a syrupy consistency.Note on donut pan: I have owned a few brands of donut pans, and I like the brand that I've linked best by far. If you prefer to make mini donuts, you will need a mini donut pan. The recipe instructions include the bake time for both standard size and mini donuts. Recipe makes approximately 48 mini donuts.
