Preheat the oven to 350°F (175°C). Grease a muffin tin or line with muffin liners.
In a small saucepan, bring the apple cider to a simmer over medium heat. Reduce the cider by half (about ½ cup). Set aside to cool.
In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, ground cinnamon, nutmeg, and salt.
In another bowl, beat the eggs, then add the melted butter, reduced apple cider, and vanilla extract. Mix well.
Pour the wet ingredients into the dry ingredients, stirring until just combined. Be careful not to overmix; it’s okay if there are a few lumps.
Fill each muffin cup about ¾ full with the batter.
Bake for 15-18 minutes or until a toothpick inserted into the center comes out clean. Allow the muffins to cool in the tin for a few minutes before removing them to a wire rack.
While the muffins are cooling, prepare the coating by mixing brown sugar and cinnamon together in a bowl.
Once the muffins are cool enough to handle, roll each muffin in the brown sugar-cinnamon mixture until fully coated.
Notes
Arrange muffins on a wooden platter, and serve with a small bowl of fresh apple slices for garnish. Dust lightly with powdered sugar for an extra touch!
