Cowboy Cookie Bars Recipe

My husband grew up in a big family and his mom often made this bar cookie recipe.  After he made it for our family I can see why – these are the best bar cookies I’ve eaten!  He doubled the amount of chocolate that his mom had listed, which probably didn’t hurt the taste one bit!

Through experimenting with the recipe, we definitely learned that a 15″ pan is key to success!  We have a 15″ jelly roll pan like this that works perfectly. We also love to serve along with these easy 4 Ingredient Cake Mix Cookie Bars in a 9 x 13″ pan.

I wondered why these are called Cowboy Cookies.  Then I thought about the corny cowboy movies my dad watches where the cowboy with the quickest draw won.  Well, this is one of the quickest batches of cookies I’ve ever made.

My husband’s family legend is that cowboys didn’t have time to make individual cookies so they always make bar cookies.

    Quick and tasty treat for the family!

    1. The quickest way to enjoy them! Thanks for stopping by & please let us know what you think 🙂

  2. Is it just me or what?. I had to call in for a jack hammer to be able to mix this and « spread ». I was lucky they were rolling asphalt on my street so they helped me with the spreading…. ouffff . In the oven now…. will see…. The mixture is SO DRY… is it normal????

    1. We were so concerned by your experience we immediately made another batch. We use softened butter, cold butter might affect the moisture, but ours turned out great. This is truly a family favorite! I hope you were able to enjoy your cookies!

    I lined my pan with parchment paper (easy clean up). I opted for the smaller quantity of chips and now I’ll be having guilt free cookies for breakfast! Bake time for me was 20 minutes. I’ll definitely be making these again and I’m already thinking about add-ins: cinnamon, coconut, nuts, wheat germ, maybe craisins…. My husband gave them a thumbs up@

    1. So glad you enjoyed them! Thanks for sharing how you’ll change up the recipe in the future!

    2. Waiting for hurricane Dorian to turn and needed to keep busy. I reduced the flour to 1 1/2 cups and added 1/2 cup flaked coconut, 1/4 cup pecan pieces, 1/4 cup craisins, and 1 teaspoon cinnamon. I made the mistake of breaking off a piece while still warm. Delicious!!!

    If you use mini chips you get better bang for your buck for the spread of the chocolate thru out the bars

    1. Love this idea! Thanks for sharing!

  5. I can’t wait to try these, but am wondering what kind of oats to use….minute or old fashioned? Thank you so much!

    1. Jennifer @ Plowing Through Life says:

      Great question! Quick oats work best. The key to making these cookies is – do not overbake. Hope you enjoy 🙂

    I only had a big cookie sheet so it took 20 minutes. I did add Walnuts to this recipe. They are delicious and taste just like our family favorite cowboy cookie recipe. I definitely will make this again.
