Key Ingredients and Substitutions

  • Yellow Cake Mix is the recipe’s star, providing a sweet and tender base. For a different taste, feel free to swap it for other flavors, like chocolate or red velvet.
  • Melted butter provides richness and keeps the bars moist. For a lighter option, you can substitute with 1/2 cup of coconut oil or unsweetened applesauce.
  • Chocolate chips are a classic choice for these bars. You can replace them with white chocolate chips, butterscotch chips, or chopped candy bars.
  • Eggs are essential for binding the ingredients and giving the bars their structure. To make it vegan, use a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water).

Making these delicious cookie bars couldn’t be easier! Just follow these simple steps, and you’ll have a batch of warm, chewy bars ready to enjoy in no time.

Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). This ensures the oven is at the perfect temperature by the time you’re ready to bake. Next, prepare your baking dish. Lightly grease it with butter or cooking spray, or line it with parchment paper.Using parchment is especially helpful for lifting the bars out later without sticking or crumbling. If you’re going the parchment route, leave some overhang on the sides to act as “handles” for easy removal.

Step 2: Mix the Ingredients
Grab a large mixing bowl and add your cake mix, melted butter, and eggs. Stir everything together until the ingredients are fully combined and form a thick, sticky batter. This step should only take a few minutes, but the rich aroma of the buttery batter will already have your taste buds anticipating what’s to come! Pro tip: Avoid overmixing; stir just until the batter comes together for the best texture.

Step 3: Add Your Mix-Ins
It’s time to customize your bars with your favorite mix-ins! Stir in a generous handful of chocolate chips, chopped nuts, or even chunks of your favorite candy bars. Make sure to mix them evenly throughout the batter so every square has those delightful bites of flavor. For a more festive touch, sprinkle in colorful candies or themed sprinkles.

Step 4: Spread the Batter
Transfer the batter into your prepared baking dish. Using a spatula or the back of a spoon, spread it out evenly, ensuring it reaches all the corners. The batter will be thick and slightly sticky, so take your time to smooth it out. This ensures the bars bake evenly and have a consistent texture throughout.

Step 5: Bake
Pop the baking dish into your preheated oven and bake for 18–22 minutes. Monitor them closely, as baking times may vary slightly based on your oven. You’ll know they’re ready when the edges are lightly golden brown, and a toothpick inserted into the center comes out clean or with just a few moist crumbs. Avoid overbaking to keep your bars soft and chewy.

Once baked, let the bars cool in the pan for about 10 minutes. This short cooling period allows them to set slightly, making them easier to cut without crumbling. Use a sharp knife to slice them into squares, rectangles, or even triangles for a fun presentation. Serve them warm for a gooey treat or at room temperature for a firmer bite.

And there you have it! In just five simple steps, you’ll have a batch of irresistible cake mix cookie bars perfect for any occasion. Whether you’re making them for a party, a family snack, or just because, these bars are guaranteed to be a hit.

Expert Tips for Success

  • Don’t Overbake: Timing is everything when baking cookie bars. Begin checking for doneness at around 18 minutes. You’re looking for edges that turn golden brown and a center that still looks slightly soft. The bars will continue to set as they cool, ensuring a chewy texture. Overbaking can lead to dryness, so keep an eye on them and err on the side of slightly underdone for the perfect result.
  • Use Parchment Paper: Save yourself the trouble of struggling to remove bars from the pan by lining it with parchment paper. This handy trick not only makes cleanup a breeze but also allows you to lift the bars out effortlessly for cutting. For the best results, leave a little overhang on the sides of the pan to use as “handles” when removing the bars.
  • Customize the Sweetness: If your mix-ins are on the sweeter side—think caramel bits, white chocolate chips, or toffee chunks—balance the flavor by choosing a cake mix with moderate sugar content. Vanilla or yellow cake mixes are great options, but you could also opt for a less sweet option like spice cake or even a sugar-free mix for a more balanced bite.
  • Chill the Dough if Sticky: If you’re finding the dough too sticky to press evenly into the pan, a quick chill in the fridge for 15 minutes can help firm it up. This step makes spreading and shaping much easier.

Variations and Customizations

  • Make it Vegan: Adapting this recipe for a vegan lifestyle is surprisingly simple. Use a dairy-free cake mix (many store-bought options qualify) and replace the eggs with flax eggs (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water per egg). Swap melted butter for coconut oil or vegan margarine, and you’ve got a delicious plant-based treat everyone can enjoy.
  • Add Fruit: Give your bars a fruity upgrade by mixing in dried fruits like cranberries, raisins, chopped dates, or dried apricots. These additions not only add bursts of flavor but also create a delightful contrast to the chewy texture of the bars.
  • Switch the Flavor: The beauty of this recipe lies in its versatility. Switch things up by using different cake mix flavors. Lemon cake mix delivers a zesty, refreshing treat, while strawberry or chocolate cake mix creates a rich and decadent dessert. Each variation feels like a brand-new recipe.
  • Holiday Twist: Match your cookie bars to the season by incorporating festive mix-ins. For Christmas, crushed peppermint candies or red and green sprinkles add a cheerful touch. During Easter, pastel M&Ms or mini candy eggs bring a playful, springtime vibe. This easy customization ensures your dessert always feels on theme.
  • Nutty Delight: Add a satisfying crunch by folding in chopped nuts like pecans, walnuts, or almonds. They not only enhance the texture but also complement the buttery richness of the bars beautifully.
  • Layered Bars: For a more indulgent twist, layer the dough with a spread of Nutella, peanut butter, or cream cheese before adding the top layer of dough. This creates a gooey, flavorful center that’s bound to impress.

  • Reheating: To keep the bars warm, pop them in the microwave for 10-15 seconds. This softens the chocolate and gives them a freshly-baked feel.

  • Drizzle with caramel or chocolate sauce for an extra indulgent treat.
