Recipe Note

The batter will be very thick. Don’t worry, this is normal!

Step 3: Grease a 9 X 13 baking dish with cooking spray. Spread the cookie bar batter evenly in the dish (this will take several minutes to spread evenly).

Recipe Tip

Use wet or greased hands or a rubber spatula to spread the batter into the dish. The batter is very thick and this will make it a little easier to spread!

Step 4: Bake the cake mix cookie bars at 350 degrees for 20-25 minutes, or until a toothpick inserted comes out clean. Once cooled, cut the cookie bars into squares.

Serve warm with ice cream for an extra delicious treat!

If you’ve never made these before, you will be surprised at just how good they are!

The texture of these bars is the thickness of a brownie with the taste of a chocolate chip cookie. They’re just so fun to eat and really satisfying and thick and chocolatey.

Notes

The batter will be thick and hard to spread (this is normal). I found that using a rubber spatula and a spoon made it easier to spread into the pan. It may take a couple minutes, but it’s so worth it! I have successfully substituted both melted butter and applesauce for the oil in this recipe. It will change the texture slightly, but is still delicious!
