These lazy chocolate chip cookie bars are a quick and easy dessert made with yellow cake mix, butter, eggs, and plenty of semi-sweet chocolate chips. With a soft, chewy texture and golden edges, this simple recipe is perfect for busy days, last-minute baking, or family treats. The thick batter comes together fast and bakes into rich cookie bars that are ideal for parties, potlucks, or everyday desserts.

Ingredients

1 box yellow cake mix
½ cup (1 stick) salted butter, melted
2 large eggs, beaten
12 oz semi-sweet chocolate chips

Instructions

Preheat the oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick spray.
Prepare the batter
In a large mixing bowl, combine the yellow cake mix, melted butter, and beaten eggs. Mix until fully combined. The batter will be thick.
Add chocolate chips
Fold in the chocolate chips until evenly distributed throughout the batter.
Spread the batter
Transfer the mixture to the prepared baking dish. Because the batter is thick, lightly grease your hands or a spatula and press it evenly into the pan.
Bake
Bake for 20–25 minutes, or until the edges are golden brown and the center is set.
Cool and slice
Allow the bars to cool completely before cutting into squares.
