Step 1

Preheat oven to 350°F.

Step 2

Line an 8-inch square baking pan with parchment paper - if you don't know how to do that, check out this tutorial for lining pans with parchment paper.

Step 3

In a medium bowl, whisk together the flour, cinnamon, baking powder, and salt. Set aside.

Step 4

In another bowl, add the brown sugar, melted butter, egg, and vanilla. Whisk until well blended. Then use a wooden spoon to stir in the flour mixture just until moistened, do not beat. Add the 1/2 cup chopped pecans and the 1/2 cup chocolate chips and gently stir into the batter.

Step 5

Add the batter to the prepared pan. Spray a spatula with cooking spray to grease and use that to evenly spread the batter. Sprinkle the extra nuts and chocolate chips on top.

Step 6

Bake at 350 degrees F for 18-22 minutes, or until a toothpick inserted in the center comes out clean and the bars are golden brown. Remove from oven and cook in the pan on a wire rack. When cool, lift the parchment paper to remove the bars from the pan. Cut into 12 squares.
