Using a hand mixer, beat in apple cider, vegetable oil, eggs, and maple extract until incorporated.
Scoop batter into lined muffin tins until about 1/2 full.
Bake for 18-20 minutes or until a tester comes out clean.
Cool completely before frosting cupcakes.
Once cupcakes are cooled, prepare frosting.
Begin by mixing together butter, salt, lemon juice, maple extract, cinnamon, and nutmeg until combined. I used a stand mixer with the whisk attachment.
Pour in half of the powdered sugar (2 cups), and apple cider and mix.
Add the remaining 2 cups of powdered sugar and blend.
Turn the stand mixer on high and beat for 5 minutes. This is to make the icing super fluffy and soft.
Frost cupcakes with icing (I used a piping bag and a Wilton 1M tip).
