Cookie bar ingredients

Ingredients you need for cake mix bars
- Cake Mix: You need one (15.25-ounce) box of cake mix for this recipe. For classic chocolate chip cookie bars, I recommend using white cake mix; however you can use yellow. Or you can use any flavor cake mix you love and get creative! (See below for yummy cookie bar flavors and variations!)
- Pudding Mix: Adding one 3.4-ounce box of instant pudding mix (the powder only), gives these bar cookies from cake mix a homemade, buttery taste and deliciously extra soft and chewy texture! You can use any flavor of pudding you like – just make sure it’s instant!
- Water: 1/4 cup of water helps make the cookie batter wet enough for chemical magic to happen in the dough!
- Substitution: For more flavor you can substitute milk!
- Oil: 3/4 cup of vegetable oil adds moisture and creates rich tasting cake bars!
- Eggs: Two large eggs bind all the ingredients together and help provide structure.
- Extract: I recommend use vanilla extract for chocolate chips bars; but, you can use any flavor extract you love! Use pure extract (versus artificial) for the best flavor.

How to make cookie bars with cake mix
- Preheat oven to 350-degrees F. Grease an 9x13x2-inch baking pan with cooking spray and set aside. (Tip: Line the greased pan with parchment paper if you want to be able to lift the cookie bars out of the pan as one whole!)
- Mix wet ingredients: In a large bowl with a hand-held mixer or a stand mixer, combine the wet ingredients on medium speed until combined.
- Add the dry ingredients: To the bowl, add the cake mix and pudding mix. Beat on low until almost combined. (The batter should be thick!)
- Add mix-ins: For chocolate chip cookie bars, add in 3/4 cup of chocolate chips along with 1/2 cup of chocolate chunks, and fold to combine. (Tip: Simple swap out the chocolate for your favorite flavor of baking morsels, chopped candy, etc. to create your own custom dessert bars!)
- Add cookie dough to pan: Pour the batter into the baking dish. Use a rubber spatula to spread and smooth the cookie batter. Sprinkle remaining chocolate chips and chunks evenly over the top of the cookie bar dough. (Tip: If using, sprinkles or sanding sugar, scatter them evenly over the top of the dough now.)
- Bake: For soft and chewy cookie bars, bake for 24-28 minutes, or until edges are golden.
- Cool: Let the cookie bars cool in the pan on a wire rack for at least 30 minutes. (Tip: For sliceable cookie bars with clean cuts, after 1 hour transfer the pan to the refrigerator. Let the ‘cookie cake’ chill for 2 hours before slicing and serving.)
- Serve: If you used parchment paper, gently lift the whole cookie cake up and out of the pan. Slice, serve and enjoy!
Tips when making this Cake Mix Dessert
- Line the pan: I recommend lining your cake pan with parchment paper so you can easily lift the cookie out of the pan, as an entire cookie cake. Your parchment paper should be a few inches longer than the baking dish so there is some paper hanging over the sides.
- Don’t over-mix: Do not over-mix the cake mix cookie dough, or your cookie bars will turn out tough and dry. Just mix until no large dry spots are visible. A few small lumps are fine.
- Press dough: The dough will be sticky, so grease your spatula with a bit of oil when spreading, pressing and smoothing it into the cake pan.
- Cake pan: This recipe uses a 9x13x2-inch rectangular cake pan. It is important to remember that the cooking time will vary if you use a different size baking dish or cake pan. This will affect how thin or thick your bars are going to be. So, make sure that you adjust your baking time accordingly.
- Cool cookie bars: Unless you want a molten cake, do not remove the cookie bar from the baking pan right away! It will still be soft and pliant right out the oven. Let it cool for 30 minutes if you like ultra-soft cookies or for 1+ hours to room temperature for soft and chewy cookie bars.
- Perfect cookie cake bars: For sliceable cookie bars with clean cuts, transfer the pan to the refrigerator after 1 hour. Let the cookie “cake” chill for 2 hours before slicing and serving!
Cookie Bars: Frequently asked questions
- Can I make the dough ahead of time and freeze it? Yes, you can! Homemade cookie doughs can be frozen for at least three months. Just make sure to keep it tightly wrapped in freezer bags. You can thaw it overnight in the fridge before baking.
- Do I need to use a particular cake mix brand? No, you don’t. You can use your fave brand to make these Cake Mix Cookie Bars.
- Can I make this gluten-free? As long as you use gluten-free cake and instant pudding mix, you can enjoy these cookie bars free of gluten.
- Can I use a block of chocolate instead? Absolutely! If you do not have chocolate chips, you can use any chocolate bar or block and simply chop them into chunks or smaller pieces.
Best ways to serve cake mix cookie bars
There are three different ways to serve this easy cake mix bars recipe: Warm, fresh from the oven as a molten cake; as a whole soft and chewy cookie cake; or slice and serve as chocolate chip cookie bars!
- Warm from the oven: Some taste testers prefer this recipe still warm, while the chocolate chips are still gooey and the cookie cake is ultra-soft and buttery! It can get messy, so this serving option is best for those who don’t mind a bit of chocolatey mess! Let the cake mix cookie cake cool slightly, about 5 minutes, before enjoying straight from the pan. To make it even more special, I recommend topping your warm white cake mix cookie with a couple scoops vanilla ice cream or dollops of cool whip! Cookie bar al a mode, anyone?
- Giant Cookie Cake: To serve as a lazy cookie cake or cookie pizza (like the famous cookie cakes at the mall!), make sure you line the cake pan with parchment paper. Let the dessert cool completely in the pan before lifting up on the parchment paper to remove the cake. Decorate with your favorite color of buttercream frosting, slice into squares and enjoy!
- Cookie Bars: For lazy cookie bars, follow the instructions above – lining the pan with parchment and removing the cookie cake bars from the pan. Cut the whole cookie cake into bars by dividing it into 8 rows by 6 rows, then serve!
- Chilled cookie bars: Store your cake mix dessert bars in the refrigerator for a cold cookie treat on hot summer days!
Storing cake mix bars
Cake mix chocolate chip bars store and freeze beautifully! Because of their cake mix and pudding base, these bars stay tender, soft and chewy for days! Before storing make sure your bar cookies are completely cool to room temperature. (Placing warm desserts in sealed containers while still warm will produce moisture that will affect the texture of the bars. It can also lead to early spoilage, which isn’t good.)
Storage tips: If you make various flavors of cake mix bars, make sure you store the different flavors separately. Also, since chewy cookie bars tend to stick together, layer a sheet of parchment or wax paper between the bars.
- Room temperature storage: Store your cake mix dessert bars in an airtight container in a cool, dry spot in your kitchen. To keep cookies soft and chewy, add a slice of bread to the container. Cookies will stay fresh for up to 5 days.
- Storing in the refrigerator: If you prefer a chilled cookie, you can store homemade bars in an airtight container in the refrigerator for up to 5 days.
- Freezer: For easy grab-and-go snacking, individually wrap the bars in a layer of plastic wrap before storing them in an airtight container or freezer-safe storage bag. Chocolate chip bars will keep for up to a couple months.
Reheating cookie bars
Nothing beats a slightly warm from the oven, soft and chewy cookie bar! Good news – with a little proper reheating, you can get those leftover bar cookies to taste just as good! The important tip to remember: you are just rewarming them, not baking them again!
- Preheat oven to 325-350 degrees Fahrenheit (Depending upon if your oven runs hot or cold).
- Place cookie bars in a single layer on a baking sheet.
- Reheat in the oven for 5 to 10 minutes, or until just warm and chewy.
This cake mix cookie bars recipe is seriously good, it should come with a deliciousness warning! Enjoy every chocolate chip bar that you can, or create your own delicious flavor, and don’t forget to share!

If you are looking for inspiration, I've included a bunch of cookie bar flavor ideas in the post above! (Make sure you use INSTANT pudding mix!)
- Extracts: If using a different stronger flavor extract, such as lemon or peppermint, you may want to reduce the amount to ¾-1 teaspoon.
- Baking Time: For ultra-soft and moist cookie bars (ooey-gooey in texture), bake for 24-26 minutes, or until the edges are just golden. Let cool in the pan on a wire rack for at least 30 minutes, depending how soft you want them!
