How to Make Cake Mix Cookie Bars
- Preheat the oven to 350°F and line a 9×13-inch baking pan with parchment paper with a slight overhang for easy removal.
- Mix the cake mix with the remaining ingredients until smooth, then fold in the chocolate chips.
- Spread the dough evenly in the pan and bake until the edges are golden and the center is set. Don’t overbake them. These bars continue to set as they cool. Pull them when the edges are lightly golden and the center looks just set for soft, chewy bars.
- Let the bars cool in the pan for 20–30 minutes before slicing.
