Serve warm with ice cream for an extra delicious treat! Everyone loves them, and I love how simple they are to throw together.

Tips for spreading the batter

My preferred way to distribute the batter evenly is by using a rubber spatula.

It will take you a few minutes to press it down into the pan, but the rubber spatula is a lot easier to use for this than other kitchen tools I have tried.

If you don’t have a rubber spatula, you can try greasing your hands to help press the batter down.

These easy 4 ingredient cake mix cookie bars are always a crowd pleaser!

Ingredients

  • 1 (15 oz) box of yellow cake mix
  • 2 eggs, beaten
  • ⅓ cup olive oil (can substitute melted butter or vegetable oil also)
  • 12 oz bag of chocolate chips

Instructions

  1. Preheat oven to 350 degrees
  2. Beat eggs in a small bowl
  3. Add cake mix and olive oil to the beaten eggs and mix well
  4. Beat in chocolate chips (batter will be very thick)
  5. Grease a 9 X 13 baking dish (see notes for thickness)
  6. Spread batter evenly in the dish (this will take several minutes to spread evenly)
  7. Bake at 350 degrees for 20 - 25 minutes, or until toothpick inserted comes out clean

Notes

  1. The batter will be thick and hard to spread (this is normal) I found that using a rubber spatula and a spoon made it easier to spread into the pan. It may take a couple minutes, but it's so worth it!
  2. The thickness of the cookie bars will depend on how large of a baking dish you use.
