These Cake Mix Chocolate Chip Cookie Bars are soft, chewy, and loaded with chocolate chips, starting with a simple yellow cake mix and just a few basic ingredients. They come together in one bowl, bake in a 9x13 pan, and make an easy, crowd-pleasing dessert for parties, potlucks, or weeknight treats.
Preheat your oven to 350°F and lightly grease a 9x13-inch baking pan or line it with parchment paper for easy removal.
Make the dough:
In a large mixing bowl, combine the yellow cake mix, melted (and slightly cooled) butter, and eggs. Stir until a thick dough forms and no dry cake mix remains.
Fold in the chocolate chips:
Stir in the chocolate chips until they’re evenly distributed throughout the dough.
Spread and bake:
Press the dough evenly into the prepared pan. Bake for about 25 minutes, or until the top is lightly golden and a toothpick inserted into the center comes out mostly clean or with a few moist crumbs.
Cool and slice:
Let the bars cool in the pan before cutting into squares. Serve as is or slightly warm with a scoop of vanilla ice cream.
Notes
Don’t overbake—remove when the edges are lightly golden and the center still looks soft.
Any flavor of cake mix works; try white, chocolate, or funfetti for a twist.
You can swap melted butter for neutral oil; the texture and flavor will be slightly different but still delicious.
Serve warm with vanilla ice cream and chocolate sauce for an easy dessert everyone loves.
