Ingredients

  • 2 sticks (8 ounces) unsalted butter
  • 1 1/2 cups (7 1/2 ounces) pecan halves
  • 3 cups rolled oats
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon kosher salt
  • 1 teaspoon ground cinnamon
  • 1 cup lightly packed dark brown sugar
  • 1 cup sugar
  • 2 large eggs, at room temperature
  • 2 teaspoons vanilla extract
  • 1/2 vanilla extract

Method

  • Preheat oven to 375.
  • Melt the butter in a heavy-bottomed skillet set over medium heat, whisking constantly, then cook until lightly browned bits form in the bottom of the skillet and the butter is light tan in color with a nutty aroma, about 8 minutes.
  • Remove from heat; butter will continue to brown even after removed from heat.
  • Transfer butter to a medium bowl and place in the refrigerator.
  • Chill for at least 1 hour.
  • Meanwhile, place the pecans on a baking sheet and bake until fragrant and browned, stirring the pecans halfway through, about 5 minutes.
  • Let cool.
  • When cool, coarsely chop.
  • Adjust oven racks to upper and lower third of the oven and reduce oven heat to 350.
  • Line two baking sheet pans with parchment paper.
  • In a medium bowl, whisk together the oats, flour, baking powder, salt and cinnamon.
  • Set aside.
  • To the bowl of a stand mixer fitted with the paddle attachment, add the browned butter, dark brown sugar and sugar (Alternately, use a large bowl and a hand-held electric-mixer.)
  • Beat on high until the mixture is fluffy, about 3 minutes.
  • Scrape down sides of the bowl with a spatula.
  • Beat in the eggs and vanilla until just combined.
  • With mixer on low, add the oat mixture in 2 batches, beating just until combined.
  • Add the chopped pecans and mix.
  • Drop 2-inch balls of dough onto prepared baking sheets using a tablespoon or small ice-cream scoop.
  • Flatten slightly using the bottom of a glass.
  • Bake, rotating and baking sheets midway through baking, until cookies are uniformly light brown, 12 to 14 minutes.
  • Let cookies cool on baking sheets until set, about 2 minutes, then transfer to a wire rack and let cool completely.
  • Serve.
