1. 1. In a medium saucepan over medium heat, melt the butter, stirring occasionally, until it turns golden brown and develops a nutty aroma. Remove from heat and let cool slightly.

2. 2. In a separate bowl, whisk together the all-purpose flour, baking powder, ground cinnamon, and kosher salt.

3. 3. In a large bowl, combine the granulated sugar, light brown sugar, and browned butter. Beat in the eggs and vanilla extract until smooth.

4. 4. Gradually mix the dry ingredients into the wet ingredients until fully combined. Cover the dough and chill in the refrigerator for at least 1 hour.

5. 5. Preheat your oven to 350°F and line baking sheets with parchment paper. Scoop the chilled dough into 1-inch balls and roll in powdered sugar to coat.

6. 6. Place the coated dough balls onto prepared baking sheets, spacing them apart. Bake for 10-12 minutes, or until set but still soft in the center. Allow to cool slightly before serving.
