Fold in 2 cups of the red, white, and blue M&M’s gently until evenly distributed.

Common Mistakes to Avoid
When making Red White and Blue M&M Cookie Bars, it’s easy to make mistakes that can affect the final product. Here are some common pitfalls to avoid.
- Incorrect Oven Temperature: Always preheat your oven to 350°F. Baking at the wrong temperature can lead to unevenly baked cookie bars.
- Not Creaming Ingredients Properly: Make sure to cream the butter and sugars until light and fluffy. This step is essential for achieving that soft and chewy texture.
- Forgetting to Fold in M&M’s: When adding M&M’s, be sure to fold them gently into the dough. This prevents them from breaking apart and maintains their vibrant colors.
- Overbaking Your Cookie Bars: Keep a close eye on your cookies while baking. Overbaking can result in dry cookie bars instead of the desired chewy texture.
- Using the Wrong Pan Size: Stick to a large rimmed baking sheet (17×12-inch) as specified in the recipe. Using a smaller pan can lead to thicker bars that require longer baking times.
