GoGo’s Oatmeal Chocolate Chip Bars

The recipe is finally here, GoGo’s Oatmeal Chocolate Chip Bars!!! 

GoGo’s Oatmeal Chocolate Chip Bars

Named after my outstanding mother-in-law, whom we call GoGo, these bars are one of her specialties in the kitchen that everyone in her life knows and loves so very much! Growing up, my husband, Clayton, says that these oatmeal chocolate chip bars were a regular staple in their house and there was almost always a batch ready to be eaten at any given time. In fact, all of his high school friends know and love GoGo’s Oatmeal Chocolate Chip Bars and always rant and rave about how they loved them growing up! GoGo took them everywhere with her, and I completely understand why. 

These chocolate chip bars are just about the easiest recipe to make, using limited ingredients and a box of yellow cake mix. It can be thrown together at any given time and taken to a friend in need of a little sweet treat, a potluck gathering or when hosting friends at your house.

GoGo’s Oatmeal Chocolate Chip Bars

While they are *fantastic* when warm or at room temperature, they are (arguably) better kept in the freezer and eaten straight out of there — a Snodgrass family secret! We carve them into squares, toss them in a ziplock and leave them in the freezer for a sweet treat whenever your heart desires or easily warmed up if that is what you prefer. But, if you do try our freezer trick,  definitely let me know what you think!

Ingredients

Instructions

  • Preheat the oven to 325 degrees and line a 9x13 metal baking pan with parchment paper.
  • In a large mixing bowl with a paddle attachment, combine the avocado oil, water, egg, softened butter, smart sugar (or brown sugar if using) and only ½ of the bag of the vanilla cake mix. Mix at medium speed until well combined.
  • Add the remaining cake mix and the oats. Mix over medium speed once more until just combined.
  • Fold in the chocolate chips. Transfer to the parchment-lined baking pan and spread into an even layer using a rubber spatula.
  • Transfer to the preheated oven and bake for exactly 30 minutes. It might not look completely done, but once it has time to set it will be perfect and still chewy in the center. *GoGo says never take it out earlier or later than 30 minutes!
    Allow the bars to cool completely, at least 30 more minutes, before lifting the parchment paper out of the baking dish and carving into squares.

Notes

  • Quick oats does not work as an alternative in this recipe!
  • 1:1 substitute for brown sugar
  • I do not like plain coconut sugar as a sub in this recipe
  • I have tried grain-free boxed yellow cake mix as an alternative and it did not work the same.

    Hi! I don’t have cake mix. Is that a deal breaker for the recipe? What would I use instead?

    Made these with vegetable oil, brown sugar and traditional yellow cake mix. So good! Highly recommend the freezer tip. They are the perfect snack and I definitely savor it more eating it out of the freezer.

    Mine didn’t set and I followed the directions to a T. The only differences being that I used olive oil instead of avocado oil and used a glass baking pan instead of metal. Do I just need to bake it longer??

      First time I made them with yellow cake mix and baked exactly 30 minutes. They were so yummy, especially frozen. I only had chocolate chunk chips and A partial bag of dark chips. I’m sure I added more than 8 oz. Anyway, the next time I used white cake mix and only 8 oz. Not nearly as good! Yellow cake and lots more chips is the way to go or should I say Go-Go!:)

    These were delicious! I used a regular boxed yellow cake mix, canola oil, and brown sugar for substitutions. I thought the recipe called for too much chocolate so I’ll use less next time. Otherwise, these were perfect!

          Used some of those tips!! Little less sugar, little more water. Temp 25′ higher since we live over 5000 feet. They turned out amazing! Love them frozen. Thank you!

    I used a sugar free yellow cake mix and regular brown sugar. The sweetness was perfect. Took them to share with fellow nurses at work and you bet they’re getting devoured. What an easy recipe!

    Just made these and my kids could hardly wait for them to cool down to eat, they are SO good!!! Made with olive oil because I didn’t have avocado oil on hand, and not a fan of using vegetable oil. Will definitely be making these as a regular staple. Thanks for another winner Alex!!

      So good! I used a 365 GF cake mix from Whole Foods and tossed in an extra 1/3 C oats. Crossed my fingers, and it worked out great!
      My 2 SILs and I are all preggo together and nibbled off the frozen stash of what was left 🙂 (not that it lasted long…)
      Everyone has made another batch!

      Love that this is a family recipe! <3

    These look incredible! I don’t like my baked goods very sweet so I’m wondering what your thoughts are about leaving out the sugar altogether? Between the Cake mix and the chocolate I’d imagine they’re sweet enough for me but not sure if it changes the baking composition. Wish I could tolerate monk fruit or other alternative sweeteners 😣
