I’ve been making these easy oatmeal chocolate chip cookie bars for almost 20 years. Talk about a tried-and-true favorite!

They are easy, no-fuss, and they will always be one of my favorite cookie bars ever. 

Soft and chewy, they are a perfect alternative to scooping out tray after tray of oatmeal chocolate chip cookies. I just love cookies in bar form. I really do.

Oatmeal Chocolate Chunk Bars

Yield: 9X13-inch pan
Prep Time: 15 minutes
Cook Time: 20 minutes
Total Time: 35 minutes

Ingredients

  • 1 3/4 cup all-purpose flour
  • 3/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup oatmeal (quick oats or rolled oats)
  • 3/4 cup (1 1/2 sticks) butter, softened
  • 1/2 cup granulated sugar
  • 1/2 cup lightly packed brown sugar
  • 1 large egg
  • 1 egg yolk
  • 1 teaspoon vanilla
  • 12 ounces semi sweet chocolate chunks or chocolate chips

Instructions

  1. Preheat oven to 375 degrees F. Lightly coat a 9X13-inch baking pan with cooking spray and set aside.
  2. Whisk together dry ingredients in a small bowl and set aside. In a large bowl with a handheld electric mixer or a stand mixer, beat butter, sugars, egg and vanilla until fluffy, about 2-3 minutes. Add the dry ingredients and chocolate chips together. Mix until combined. Press into the prepared pan and bake for 18-20 minutes until light golden brown. Don't overbake! These bars are definitely better underbaked by just a few minutes rather than being overbaked so watch them carefully. Let cool completely on a wire rack before slicing into squares.

Notes

Doubling: I almost always double this recipe and press the dough into a large 11X17-inch rimmmed sheet pan.

Chocolate Chips: they are delicious with any assortment of chocolate chips (butterscotch, mint, etc.).
