These Cake Mix Chocolate Chip Cookie Bars are a quick, fun way to make dessert without much fuss. Easy to make and fun to bake with kids, they’re a perfect go-to when you need a fast sweet treat.

Bars are a great alternative to cookies because there’s no scooping or shaping—just press into the pan and bake. These are soft, chewy, and packed with classic chocolate chip cookie flavors. They bake up golden with a melt-in-your-mouth texture.

What You Need To Make These Cookie Bars

It’s always smart to check your pantry and pick up everything in advance so you’re ready to bake without last-minute store runs. Once you’ve got what you need, the rest is quick and easy and you can make them whenever you want to!

Got Leftovers??

Keep leftover bars in an airtight container at room temperature for 3–4 days. You can also freeze them if you need to. Lay in a freezer bag or a freezer container with layers of parchment between them. Freeze for up to six months.
