Method
Make the cupcakes
- Simmer the apple cider in a small saucepan over medium heat until reduced to 1/2 cup, about 10 to 15 minutes.
- Cool the cider reduction to room temperature.
- Heat the oven to 350°F and line a standard 12-cup muffin pan with paper liners.
- Whisk the flour, baking powder, baking soda, cinnamon, nutmeg, and salt in a medium bowl.
- Whisk the vegetable oil, brown sugar, egg, sour cream, and vanilla in a large bowl until smooth.
- Whisk the cooled cider reduction into the wet mixture.
- Fold the dry mixture into the wet mixture just until no dry flour remains.
- Divide the batter evenly among the liners.
- Bake for 18 to 22 minutes, until the tops spring back lightly and a toothpick inserted in the center comes out with a few moist crumbs.
- Cool the cupcakes in the pan for 5 minutes.
- Transfer the cupcakes to a wire rack to cool completely.
Make the frosting
- Beat the butter in a medium bowl until smooth.
- Gradually beat in the powdered sugar.
- Add the milk and beat until fluffy.
Frost the cupcakes
- Spread the frosting over the completely cooled cupcakes.
Notes
For a tender crumb, fold the dry mixture in only until no dry flour remains. Store frosted cupcakes in the refrigerator for up to 3 days; freeze unfrosted cupcakes for up to 2 months. For a dairy-free variation, use dairy-free butter, milk, and sour cream.
