Gooey Cake Mix Cookie Bars


  • 1 (15.25 oz.) box white cake mix
  • 1/2 cup canola oil
  • 2 eggs
  • 1/2 cup (1 stick) unsalted butter, melted
  • 1/2 cup semi-sweet chocolate chips
  • 1/2 cup butterscotch or peanut butter chips
  • 1 (14 oz.) can sweetened condensed milk
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt, optional


  1. Preheat oven to 350º F and lightly grease a 9×13-inch baking dish with butter or non-stick spray.
  2. In a large bowl, beat together cake mix, canola oil, eggs and vanilla extract, mixing until mixture just comes together.
  3. Divide batter in half and press one half into prepared baking dish to form an even layer.
  4. In a medium, heat-proof bowl, butter, chocolate chips and butterscotch chips, then microwave in 30-second intervals, stirring in between, until mixture is fully melted and smooth.
  5. Stir condensed milk and salt, if using, into chocolate chip mixture until completely incorporated, then pour over base cake layer.
  6. Drop spoonfuls of remaining batter over chocolate chip middle layer, then place baking dish in oven.
  7. Bake for 20-25 minutes, or until top is golden brown, then remove from oven and let cool.
  8. Once cool, slice into bars, serve and enjoy!
