• Vanilla Extract – Enhances the overall flavor profile; consider using almond extract for a different twist.
• Baking Soda – A leavening agent that helps cookies rise; ensure it’s fresh for best results.

Step‑by‑Step Instructions for Red White and Blue Chocolate Chip Cookie Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Prepare a 9×13 inch baking pan by lining it with foil, allowing some overhang, and lightly spraying it with cooking spray. This will prevent your Red White and Blue Chocolate Chip Cookie Bars from sticking, ensuring easy removal later.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together 2 1/4 cups of all-purpose flour, 1 teaspoon of baking soda, and 1/2 teaspoon of salt. This combination will add structure and flavor to the cookie base. Once mixed, set this dry mixture aside while you prepare the wet ingredients, ensuring they’re ready to combine smoothly.
Step 3: Cream Butter and Sugars
In a large mixing bowl, beat 1 cup of unsalted butter with 1 cup of granulated sugar and 1/2 cup of packed brown sugar using a hand mixer on medium speed for about 2 minutes, until the mixture is light and creamy. This step is crucial for creating the rich, buttery texture that your cookie bars will boast.
Step 4: Add Eggs and Vanilla
Add 2 large eggs and 2 teaspoons of vanilla extract to the creamed mixture. Continue to beat on medium speed for another minute until everything is fully combined. The mix should be smooth and fluffy, indicating that your wet ingredients are well incorporated, forming the base for your cookie bars.
Step 5: Combine Wet and Dry Ingredients
Gradually mix the reserved dry ingredients into the butter mixture using a spatula, stirring until just combined. Be careful not to overmix; a few flour streaks are okay. Fold in 1 cup of mini chocolate chips and 1 cup of vanilla milk chips, ensuring an even distribution for a delightful chocolatey flavor in every bite.
Step 6: Spread the Dough
Pour the cookie dough into the prepared pan, using a spatula to spread it evenly across the bottom. Ensure it reaches the corners and sides of the pan for uniform baking. The dough should look thick and rich, ready to transform into delicious cookie bars once baked.
Step 7: Bake
Place the pan in the preheated oven and bake for 30–35 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out clean. Keep an eye on the bars as they bake; the goal is a soft, chewy center surrounded by golden edges, embodying the perfect texture.
Step 8: Cool Before Frosting
Once baked, remove the pan from the oven and allow the cookie bars to cool in the pan for at least 30 minutes. This cooling period is essential before moving on to frosting; it will help ensure that the vanilla buttercream adheres properly and doesn’t melt.
Step 9: Prepare the Frosting
While the bars cool, prepare the vanilla buttercream by beating 1/2 cup of unsalted butter, 3 cups of powdered sugar, 2 tablespoons of heavy cream, 1 teaspoon of vanilla extract, and a pinch of salt in a bowl. Mix on medium speed until creamy and smooth, about 2–3 minutes, creating a luscious topping for your cookie bars.
Step 10: Frosting and Decorating
Once the cookie bars are cool, spread the buttercream evenly over the top using an offset spatula. While the frosting is still soft, generously sprinkle them with colorful M&Ms and festive sprinkles, allowing the decorations to adhere nicely before the frosting sets.
Step 11: Cut and Serve
Using a sharp knife, cut your cooled and frosted Red White and Blue Chocolate Chip Cookie Bars into small squares or rectangles. Serve them fresh at your next gathering, making sure to showcase their vibrant colors and delicious flavors, perfect for celebrating any occasion!

Make Ahead Options
These Red White and Blue Chocolate Chip Cookie Bars are perfect for busy home cooks looking to streamline their meal prep! You can prepare the cookie dough up to 24 hours in advance by mixing it and then covering it tightly with plastic wrap before refrigerating. The vanilla buttercream frosting can also be made up to 3 days ahead; simply store it in an airtight container in the fridge. When you’re ready to bake, let the dough sit at room temperature for about 15 minutes to soften slightly before spreading it in the pan. After baking and cooling, frost the bars, add your colorful toppings, and they’ll taste just as fresh as if you made them that day—saving you time and stress for your next gathering!
