How to Make 4th of July Cake-Mix Cookie Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F. This step ensures that your cookie bars bake evenly and develop a nice golden color.
Step 2: Prepare the Baking Pan
Spray a 9×13 baking pan with cooking spray and line it with parchment paper. This prevents sticking and makes cleanup easier.

In a medium mixing bowl, combine yellow cake mix, eggs, and softened butter. Stir until smooth. It should have a creamy texture without lumps.

Fold in M&M’s until they are evenly distributed throughout the batter. This step adds color and crunch to your cookie bars.
Step 5: Spread the Batter
Spread the batter into the prepared pan using a spatula. Ensure it’s even across all corners for uniform baking.
Step 6: Bake
Bake for 20-25 minutes or until golden brown on the edges. Keep an eye on them towards the end to avoid over-baking.
