These cookie bars are one of those treats I think about when I'm watching TV late at night and craving something sweet and easy to make! Can anyone relate? They're the best when they're still a bit warm, and I top a square with a scoop of vanilla ice cream and some chocolate syrup!

I also love making them along with other baked goods during the holidays, like these gingerbread cookie bars, chocolate dipped shortbread, chocolate crinkle cookies with cake mix, and Christmas crack, because they're an easy addition and super yummy!

Why you'll love this recipe

• Quick: This is a super simple recipe made with a box cake mix to speed the baking process up! It'll only take a few minutes to make the batter, and then the oven will do the rest of the work!
• Easy: All you need is five ingredients to make these delicious bars!
• Customizable: This recipe can be made in various ways with different add-ins like chocolate chunks, M&M's, nuts, etc!
• Incredibly Delicious: These have the flavour of a decadent chocolate chip cookie and the texture of a brownie. What else can one ask for?!

Recipe Ingredients

• Yellow Cake Mix: Boxed yellow/golden cake mix makes this recipe so quick!
• Vegetable Oil: Flavorless oil works perfectly in a dessert recipe like this and makes the bars super moist!
• Vanilla Extract: A bit of vanilla extract goes a long way in enhancing the flavour!
• Eggs: The eggs help bind the cookie bars and make them chewy. The batter can be slightly easier to mix if they're room temperature, but this is optional.
• Chocolate Chips: This recipe uses chocolate chips, but you can use milk chocolate chips if you prefer!

See the recipe card below for the ingredient measurements. 

Step-by-Step Instructions

1. Prepare: Preheat the oven to 350 degrees Fahrenheit and spray a 9x13 baking dish with cooking spray.

2. Mix: In a large bowl, combine and mix the cake mix, vegetable oil, vanilla, and eggs using an electric hand mixer (the batter will be thick and sticky). Use a rubber spatula to fold in the chocolate chips.

3. Bake: Transfer and press the batter into the baking dish (to help with the stickiness, grease your spatula with cooking spray and use it to press the batter into the dish). Bake for 20-22 minutes or until the edges become golden. Transfer to a cooling rack and wait until it's completely cooled before cutting it into squares.

Storage and Leftovers

Cut into squares and store them in an airtight container at room temperature for up to one week or in the freezer for up to 3 months.

Kitchen Equipment

• Mixing Bowl: For making the batter.
• Electric Hand Mixer: This is used to mix the cookie batter.
• Rubber Spatula: This is used to fold the chocolate chips into the batter and press the batter into the baking dish easily.
• 9x13 Baking Dish: For baking the cookie bars.
• Cooling Rack: For resting.
• Knife: For cutting the bars into squares.

Helpful Tips

• Spray your spatula. Pressing the batter into the baking dish will be easier if you spray your rubber spatula with cookie spray to avoid it sticking to your hands.
• Wait to cut the bars. You'll want to ensure the cookie bars are completely cooled before cutting them into squares; otherwise, they'll be gooey and oozing everywhere (while that sounds delicious, it can be quite a mess!)
• Avoid parchment paper. While it may seem like a good idea to put some parchment paper in your baking dish before adding the batter so that it's easy to remove after baking, it will be difficult to spread the sticky batter on it. Cooking spray is your best bet for baking these bars!

Add-Ins & Alternative Ingredients

• Butter: You can substitute the vegetable oil for melted butter, but just be sure it's cooled down slightly before adding it to the batter!
• Milk Chocolate Chips: These taste great with milk chocolate chips and make the bars a bit sweeter!
• Ice Cream: A scoop of vanilla ice cream on top of these bars tastes amazing!
• Chocolate Sauce: Chocolate sauce puts the cherry on top when you're adding some ice cream. You can use any store-bought chocolate sauce or make your own chocolate sauce!
• Nuts: Some chopped pecans or walnuts would taste delicious in these bars!
