Red, White & Blue Cookie Bars

Posted on

These cookie bars are festive, easy to make, and the perfect chocolate chip cookie bites! They’re soft inside, crispy on the edges, and packed with chocolate chips, M&Ms, and sprinkles!

I’m back with another cookie recipe in bar form, and these are sooooo good. I kept coming back for more and ended up eating half the tray myself! I love cookie bars because they save the time and effort of scooping and rolling cookies. Plus, this recipe requires no chilling time—just mix the ingredients and get it straight into the oven! They’re packed with chocolate chips, M&Ms, and sprinkles, making them heaven in cookie bar form!

Recipe Tips:

  • Sprinkles: Not all sprinkles work well in this recipe. I used a mix of confetti quins and classic jimmies in red, white, and blue. Avoid nonpareils, as they bleed color into the batter. If you want to use nonpareils, try them in recipes like Christmas Kiss Cookies instead.
  • Baking Pan: Use a metal baking pan for even baking. Metal pans cook more evenly than glass and are easier to transport (especially if they come with a lid!).
  • Frosting: These bars are delicious without frosting, so feel free to skip it if you’re short on time or ingredients. However, frosting adds a festive touch!
  • Chocolate Chips: I prefer milk or semi-sweet chocolate chips for this recipe, but use whatever you have on hand.
  • Soft and Chewy Texture: To keep these bars soft and chewy, don’t skip the cornstarch. It creates a tender cookie. Also, bake them for exactly 24 minutes. The edges will be golden brown, and the inside will seem underbaked. Let them cool completely in the pan for the perfect texture.
