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, leaving some overhang. This will help you remove the cookie bars easily once they’re baked. Spray the foil generously with nonstick cooking spray to prevent sticking.
Step 3: Mix Butter and Sugars
In the bowl of a stand mixer, beat together butter, granulated sugar, and brown sugar. Mix until fluffy and well combined.
Step 4: Add Eggs and Vanilla
Add in the eggs and vanilla extract, continuing to beat until everything is incorporated smoothly.
Step 5: Combine Dry Ingredients
Lower the speed of your mixer. Gradually add in flour, baking soda, and salt. Mix just until combined; be careful not to overmix.
Step 6: Fold in M&M’s and Chocolate Chips
Add in the Red (White & Blue M&M’S) and mini chocolate chips. Stir gently by hand, reserving some for topping later.
Step 7: Transfer Dough to Baking Dish
Transfer your cookie dough into the 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 the cookie dough for an extra pop of color.
Step 9: Bake
Bake in your preheated oven for about 30 to 35 minutes. Keep an eye on them as baking times may vary slightly based on your oven.
Step 10: Cool and Cut
Once baked, let your cookie bars cool completely in the pan before lifting them out using the foil overhang. Cut into squares or rectangles as desired.

How to Perfect Red, White & Blue M&M’S Cookie Bars
Achieving the ideal texture and flavor in your cookie bars is simple with a few helpful tips.
-
Use room temperature butter: This helps create a fluffy texture when creaming with sugars, leading to softer cookie bars.
-
Don’t overmix the dough: Mix until just combined after adding flour and baking soda to keep the bars chewy rather than tough.
-
Chill the dough (optional): If time permits, chilling the dough for 30 minutes can enhance flavors and improve texture.
-
Check doneness carefully: Bake until the edges are golden brown but the center looks slightly underbaked; it will continue cooking as it cools.
-
Cut when cool: Allow the cookie bars to cool completely before cutting to ensure clean edges and perfect squares.
Best Side Dishes for Red, White & Blue M&M’S Cookie Bars

Common Mistakes to Avoid
When making Red, White & Blue M&M’S Cookie Bars, it’s easy to slip up. Here are some common mistakes and how to avoid them.
- Skipping the butter temperature: Using cold butter will lead to dense cookie bars. Make sure your butter is at room temperature for a fluffy texture.
- Overmixing the dough: Mixing too long after adding flour can make your bars tough. Mix just until combined for a tender result.
- Not measuring flour correctly: Too much flour can dry out your bars. Use the spoon-and-level method for accurate measurements.
- Ignoring baking time: Every oven is different. Start checking your cookie bars a few minutes before the recommended baking time to prevent overbaking.
