Add the butter to a pan and cook over medium heat allowing the butter to melt. Whisk the butter and continue cooking until brown bits start to form. Remove from the heat and set aside to allow it cool down to room temperature.
½ c unsalted butter
Preheat the oven to 350℉ and line a cookie sheet with parchment paper.
In a medium sized mixing bowl, combine the flour, baking soda, baking powder, salt, cinnamon, nutmeg, and apple cider packet together reserving 1 teaspoon of the apple cider mix for the icing that you will make later. Mix until combined.
1 ¾ c all-purpose flour flour, ½ teaspoon baking soda, 1 teaspoon baking powder, ¼ teaspoon salt, 1 teaspoon cinnamon, ½ teaspoon ground nutmeg, 1 packet apple cider mix
In the bowl of a stand mixer fitted with a paddle attachment, cream together the brown butter and sugars.
½ c unsalted butter, ¼ c granulated sugar, ½ c brown sugar
Add the egg and vanilla extract, continuing to mix until smooth.
2 teaspoon vanilla extract, 1 egg
Slowly add the dry ingredients continuing to mix on low until just combined.
Roll a tablespoon of the dough into a ball or use a tablespoon-sized cookie scoop to place the dough onto the parchment paper lined baking sheet. Bake for 8-10 minutes. Remove from the oven and allow to cool slightly before transferring to a cooling rack.
Combine the ingredients for the apple cider icing in a bowl and whisk until smooth and no lumps remain. Adjust the amount of water as needed to get the right consistency for the icing. Drizzle the cookies with the icing using a piping bag.
