The Secrets to Perfectly Chewy Blondies

The difference between a dry, cakey blondie and a perfectly dense, chewy one comes down to a few simple secrets. This recipe for Fireworks Blondies is designed for ultimate chewiness.

• Brown Sugar is King: This recipe uses a high ratio of brown sugar. The molasses content in brown sugar provides a huge amount of moisture and a rich, butterscotch-like flavor that is the signature of a great blondie.
• Melted Butter for Density: While many cookie recipes call for creaming softened butter and sugar, using melted butter (as we do here) prevents too much air from being incorporated into the batter. This results in a denser, fudgier, and chewier final product.
• The “Underbaking” Rule: This is the most important rule of all! You must err on the side of underbaking these blondies. The edges should be golden brown, but the center should look just set and still be slightly gooey. The residual heat from the hot pan will continue to cook them as they cool (a process called “carryover cooking”), resulting in that perfect, soft and chewy center.

The Key Ingredients for Your Fireworks Blondies

This recipe for Fireworks Blondies uses simple, easy-to-find pantry staples.

• Butter and Sugars: A combination of unsalted butter, packed light brown sugar, and granulated sugar creates the perfect chewy texture and rich, butterscotch flavor.
• The “Fireworks”:
  • Red, White, and Blue M&Ms: These are the star of the show! They provide a pop of patriotic color, a chocolatey flavor, and a fun, crunchy texture.
  • Patriotic Sprinkles: A festive blend of red, white, and blue sprinkles adds extra color and fun throughout the blondies. You can typically find these seasonally around Memorial Day and the 4th of July.
• The Staples: All-purpose flour, eggs, salt, baking powder, and vanilla extract provide the structure and classic flavor base for our Fireworks Blondies.

Step-by-Step Guide to Your Fireworks Blondies

This one-pan dessert is incredibly simple to mix up and bake.

1. Prepare Your Pan and Oven: Preheat your oven to 350°F. Line a 9×13-inch pan with foil, leaving an overhang on the two long sides to act as a “sling.” Spray the foil well with nonstick cooking spray. This sling is the secret to easily lifting the entire block of blondies out of the pan for neat slicing later.
2. Mix the Wet Ingredients: In a large bowl using a stand or hand mixer, mix the melted (but not hot) butter and the brown sugar until they are crumbly. Mix in the 2 large eggs and the vanilla extract until the mixture is smooth.
3. Add the Dry Ingredients: Mix in the salt and baking powder. Then, gradually add the all-purpose flour, mixing on low speed until it is just combined. Do not overmix! Overmixing the flour will develop too much gluten and result in tough, dry blondies.
4. Fold in the “Fireworks”: Gently stir in the 2 cups of red, white, and blue M&Ms and the 1/2 cup of patriotic sprinkles until they are evenly distributed throughout the dough.
5. Press Into the Pan: The dough for your Fireworks Blondies will be very thick and sticky.
   • Pro-Tip: Spray your hands or a spatula with nonstick cooking spray. This will allow you to press the sticky dough into the prepared pan and smooth it into an even layer without it sticking to you.
6. Add Extra Toppings: For an even more festive look, press some extra M&Ms and sprinkles into the top of the dough before baking.
7. Bake and Cool: Bake for 22-25 minutes. The edges will start to turn golden brown, and the center should look just set. Remember to underbake them slightly! Let the Fireworks Blondies cool completely in the pan on a wire rack before lifting them out with the foil sling and slicing them into squares.
