Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper and set it aside.
In a large mixing bowl, whisk together your browned butter, white granulated sugar, and brown sugar until well combined. Add in the vanilla extract and both eggs, whisking until the mixture becomes smooth and glossy.
Next, pour in your dry ingredients: the flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Fold everything together with a spatula until a thick dough forms.
Using a 2-inch cookie scoop, form dough balls and place them on the prepared baking sheet, leaving about 2 inches between each ball.
Bake the cookies for about 12 minutes, or until they have spread out and crinkles appear on the surface.
