• Let’s gather what you need for these festive treats!

For the Cookie Bars

Yellow Cake Mix – Provides sweetness and structure; substitute with chocolate or gluten-free cake mix for a different flavor.
Large Eggs – Adds moisture and binds the ingredients together; consider egg substitutes for dietary needs.
Butter – Contributes richness and flavor; can be replaced with margarine or a dairy-free butter alternative.
M&M’s – Adds color and crunch; opt for red, white, and blue for a festive touch or other candies for a fun twist.

Step‑by‑Step Instructions for 4th of July Cake-Mix Cookie Bars

Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). Meanwhile, take a 9×13 baking pan and generously coat it with cooking spray. For easier removal later, line the bottom and sides with parchment paper, allowing some overhang. This will not only prevent sticking but also help you lift out the cookie bars once baked.

Step 2: Mix the Batter
In a medium-sized mixing bowl, combine the yellow cake mix, large eggs, and softened butter. Use a spatula or a hand mixer to blend until a smooth, thick batter forms, which should take about 2-3 minutes. Be sure to scrape down the sides of the bowl to ensure all ingredients are fully incorporated. The consistency should be creamy and slightly thick, setting the stage for your 4th of July Cake-Mix Cookie Bars.

Step 3: Fold in the M&Ms
Gently fold in the colorful M&Ms using a spatula. Distribute them evenly throughout the batter, creating an inviting mix of colors that signifies festivity. Take care not to overmix, as this will keep your cookie bars soft and chewy. This step should only take about 1 minute; you’ll want to see bright bursts of candy throughout.

Step 4: Spread the Batter
Transfer the cake batter into the prepared baking pan, pouring it in the center first. Use the spatula to spread the batter evenly across the pan, ensuring the edges are filled and the top is relatively smooth. Aim for a uniform thickness, which should be about half an inch. This will help with even baking and ensure perfect squares when cut.

Step 5: Bake to Perfection
Place the baking pan into the preheated oven and bake for 20 to 25 minutes. Keep an eye on your 4th of July Cake-Mix Cookie Bars; they are ready when the edges turn golden brown and a toothpick inserted in the center comes out clean. The aroma will fill your kitchen, making it hard to resist the temptation!

Step 6: Cool and Cut
Once baked, remove the pan from the oven and allow it to cool for about 10-15 minutes. Carefully lift the cake bars out of the pan using the parchment overhang. Place them on a cutting board and slice into squares with a sharp knife. The vibrant colors of the M&Ms should peek through, showcasing the festive nature of these cookie bars, making them ready for any summer gathering.

Mixing Technique: Avoid overmixing the batter; stop as soon as everything is combined to keep your 4th of July Cake-Mix Cookie Bars soft and chewy.
Precise Baking Time: Watch your baking time closely; check for doneness around 20 minutes to avoid dry cookie bars. They should be golden at the edges and still soft in the center.

Cooling Tip: Allow the cookie bars to cool in the pan for a short while, then lift them out using the parchment paper for an easier cut and perfect presentation.
