For the Cookie Bars
- 2 sticks of butter (at room temperature)

- 3 large eggs
- 1 1/2 teaspoons of pure vanilla extract
- 3 cups of all-purpose flour

How to Make Red, White & Blue M&M’S Cookie Bars
Step 1: Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit. This ensures that your cookie bars bake evenly.
Step 2: Prepare Your Baking Dish
Line a 9×13 aluminum baking dish with foil. Leave some overhang on the sides; this will help you lift out the cookie bars later. Spray the foil generously with nonstick cooking spray.
Step 3: Cream Butter and Sugars
In the bowl of a stand mixer, beat together the butter, granulated sugar, and brown sugar until fluffy. This step helps incorporate air for lighter bars.
Step 4: Add Eggs and Vanilla
Add in the eggs one at a time along with the vanilla extract. Continue to mix until well combined.
Step 5: Mix Dry Ingredients
Lower the mixer speed and add in the flour, baking soda, and salt. Mix until just combined; avoid overmixing to keep your bars soft.
Step 6: Incorporate Chocolates
Fold in the Red, White & Blue M&M’S and mini chocolate chips using a rubber spatula. Reserve some M&M’S and chocolate chips for topping later.
Step 7: Transfer Dough to Baking Dish
Spoon the cookie dough into your prepared baking dish. Spread it evenly across the bottom.
Step 8: Add Toppings
Press additional M&M’S and mini chocolate chips into the top of your cookie dough for an extra delightful look.
Step 9: Bake
Place in preheated oven and bake for about 30 to 35 minutes or until golden brown around the edges.
Step 10: Cool and Cut
Once baked, allow the cookie bars to cool completely before cutting them into squares. Enjoy!

Common Mistakes to Avoid
When making Red, White & Blue M&M’S Cookie Bars, it’s easy to make a few common mistakes. Here are some tips to help you achieve perfect cookie bars.
- Not Using Room Temperature Butter: Cold butter won’t cream well with the sugars, leading to dense bars. Make sure your butter is at room temperature for the best texture.
- Overmixing the Dough: Mixing too much once you add the flour can lead to tough cookie bars. Mix until just combined to keep them soft and chewy.
- Skipping the Baking Spray: Not greasing your baking dish can result in sticking. Always use nonstick cooking spray on your foil lining for easy removal.
- Not Pressing in Toppings: Failing to press extra M&M’s and chocolate chips into the top can result in uneven topping distribution. Be generous when pressing them in for a beautiful finish.
- Underbaking or Overbaking: Baking for too little or too long can ruin your bars. Aim for a golden brown edge and a slightly soft center for optimal results.
