Cranberry-Nut Oatmeal Cookies

Preheat oven to 350 degrees F (175 degrees C). Place an oven rack in the upper third of the oven. Line baking sheets with parchment paper. Place unsalted butter and light brown sugar into the work bowl of a stand mixer and mix on medium-slow speed until very fluffy, 3 to 4 minutes. Beat in the vanilla extract, followed by eggs, one at a time. Reduce mixer speed to lowest speed and leave running. In a separate bowl, whisk together the rolled oats, flour, baking powder, cinnamon, kosher salt, and nutmeg. Pour the dry ingredients into the slowly running mixer in thirds; mix in dried cranberries and nuts until just incorporated. Using a large cookie scoop, place dough on prepared baking sheet about 2 inches apart. Bake one batch at a time in the preheated oven just until the edges are brown, 17 to 18 minutes. Allow to cool on baking sheets for about 5 minutes before removing to finish cooling on wire racks.
