• Preheat the oven to 350° F. Line a 9×13 inch baking dish with parchment paper and set aside.
• Add butter to a skillet set over medium heat. Allow the butter to brown until it smells toasted, about 2-3 minutes. Remove from the heat and pour the brown butter into a mixing bowl. Let cool for 5 minutes.
  1 cup salted butter
• Add the brown sugar, maple syrup, apple butter, egg, and vanilla into the mixing bowl. Mix until creamy.
  1 cup dark brown sugar, 1/4 cup maple syrup, 1/4 cup apple butter, 1 large egg, 2 tsp vanilla extract
• Add in the flour, baking powder, cinnamon, and salt. Mix until almost fully combined. Fold in chocolate chips and chunks/pecans.
  2 1/3 cups all-purpose flour, 1 tsp baking powder, 1/2 tsp ground cinnamon, 1/2 tsp salt, 1 cup semi-sweet chocolate chips, 1/2 cup chopped pecan
