Ingredients
  

For the Dry Ingredients
  • 1 1/2 cups All-purpose flour
  • 2 cups Rolled oats old-fashioned
  • 1 tsp Baking soda
  • 1/2 tsp Salt
For the Wet Ingredients
  • 1 cup Unsalted butter 2 sticks, melted and cooled
  • 1 cup Light brown sugar packed
  • 1/2 cup Granulated sugar
  • 2 Large eggs room temperature
  • 2 tsp Vanilla extract
For the Mix-ins
  • 1 1/2 cups Semi-sweet chocolate chips
  • 1/2 cup Chopped walnuts optional

Equipment

  • Air Fryer
  • 9x13 inch baking pan
  • Parchment Paper
  • Large Mixing Bowl
  • Medium Mixing Bowl
  • Electric Mixer
  • Measuring cups and spoons
  • Rubber Spatula

Method
 

Prepare the Pan
  1. Preheat oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving an overhang on the sides for easy lifting. Set aside.
Combine Dry Ingredients
  1. In a medium bowl, whisk together the all-purpose flour, rolled oats, baking soda, and salt. Set aside.
Cream Wet Ingredients
  1. In a large mixing bowl, combine the melted and cooled butter, packed light brown sugar, and granulated sugar. Beat with an electric mixer or whisk until creamy and well combined.
Add Eggs and Vanilla
  1. Beat in the large eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract until just combined.
Combine Wet and Dry
  1. Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed or by hand with a spatula until just combined. Be careful not to overmix.
Fold in Mix-ins
  1. Gently fold in the semi-sweet chocolate chips and chopped walnuts (if using) until evenly distributed throughout the dough.
Press into Pan
  1. Transfer the dough to the prepared 9x13 inch baking pan. Using a rubber spatula or your hands, press the dough evenly into the pan, making sure it reaches all corners.
Bake
  1. Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with moist crumbs (not wet batter). Do not overbake to ensure chewiness.
Cool & Serve
  1. Let the bars cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang. Once cooled, cut into 24 squares and serve.

Notes

For extra chewiness, do not overbake the bars. Store leftover bars in an airtight container at room temperature for up to 3-4 days, or freeze for longer storage. You can customize these bars by adding different mix-ins like white chocolate chips, dried cranberries, or shredded coconut.
