Whole wheat chocolate chip cookie bars are the variation on the classic that you definitely need to make! Baking them into bars instead of individual cookies makes these one of the EASIEST baked desserts out there.

These cookie bars have a delicious nutty flavor thanks to the whole wheat, and they are delightfully crisp on the outside and chewy in the center. Adding walnuts is optional, but I honestly can’t imagine the bars without them.

How to make whole wheat chocolate chip cookie bars

Have I mentioned how EASY cookie bars are to make?

  1. Mix dough. These bars use the creaming method to combine the butter with sugars, then eggs and vanilla are mixed in, followed by the dry ingredients, and finally the chocolate and walnuts.
  2. Dump into pan. Add all of the cookie dough to a prepared 8-inch square pan and pat it into an even layer.
  3. Bake. Bake cookie bars until golden and set, about 25-30 minutes.
  4. Cool and slice. For sliceable bars, let them cool completely. Then, slice and enjoy!

Cookie bar baking tips

  • You can use either an 8 or 9-inch baking pan. 8-inch will produce thicker bars and will need a longer baking time.
  • I highly recommend lining your baking pan with parchment paper, that will make it easy to remove the cooled baked bars from the pan for easy slicing on a cutting board.
  • Feel free to use your favorite chocolate chips or chunks for this recipe per your preference— milk, semi-sweet, dark, etc.
  • Chopped walnuts are an optional addition, but I love the flavor combo with the whole wheat and chocolate.
  • Pulling the cookie bars from the oven a little early will produce bars that are more gooey in the middle, but will set up during cooling. Letting the cookie bars bake for longer will produce bars that are thicker and lighter. These bars will be delicious either way! Ovens vary, so the baking time will vary.
  • I usually let the bars cool for about 15-20 minutes in the pan until they’re somewhat sturdy, and then I transfer them to a wire rack to cool completely before slicing.
  • Alternative serving suggestion: Serve warm straight from the oven and scoop portions into bowls. Top with vanilla ice cream, and chocolate or caramel sauce, if desired. Yum!

  • ¾ cup unsalted butter , at room temperature (169 grams)

  • Preheat oven to 375°F. Line an 8 or 9-inch baking pan with parchment paper with overhanging sides.
  • In the bowl of a stand mixer fitted with a paddle attachment or with a hand-held mixer, beat the butter and sugars on medium high speed until light and creamy, about 3-4 minutes. Scrape down the bowl as needed. Add the egg and vanilla.

  • Press dough into the prepared baking pan and bake until golden brown, 20-30 minutes (depending on pan size). Let cool for about 15 minutes in the pan, then lift bars out of the pan with the overhanging parchment paper and let cool completely on a wire rack. Slice into bars and serve.
