Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Unsalted Butter: Use one cup of unsalted butter for that rich flavor; don’t skimp on quality here.
Brown Sugar: Light brown sugar gives these blondies their signature chewiness; dark brown adds depth if you prefer.
Granulated Sugar: Just a bit balances the flavors and adds sweetness without being overpowering.
Eggs: Two large eggs help bind everything together for that perfect texture—room temperature works best!
Vanilla Extract: A splash of pure vanilla extract enhances the overall flavor profile beautifully.
All-Purpose Flour: For structure, you’ll need 1 ¾ cups of all-purpose flour; sift it if you want an extra-light texture.
Baking Powder: Just half a teaspoon gives these blondies that perfect lift. For more inspiration, check out this more delicious dessert recipes recipe.

Chocolate Chips or Chunks: Use one cup of semi-sweet or dark chocolate chips for a delightful chocolatey surprise in every bite.
Rainbow Sprinkles: Add three tablespoons of rainbow sprinkles for that festive touch—because who doesn’t love color?

How to Make Fireworks Blondies
Preheat Your Oven and Prepare Your Pan: Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan with cooking spray or line it with parchment paper for easy removal.
Melt the Butter: In a medium saucepan over low heat, melt one cup of unsalted butter until bubbly but not browned. Allow it to cool slightly before mixing in sugars.
Add Sugars and Vanilla: Remove from heat and stir in one cup of brown sugar and half a cup of granulated sugar until smooth. Mix in two large eggs and one tablespoon of vanilla extract until well combined.
Sift Dry Ingredients: In a separate bowl, whisk together 1 ¾ cups flour, half a teaspoon of baking powder, and a pinch of salt. Gradually fold this mixture into your wet ingredients using a spatula until just combined—don’t overmix!
Add Chocolate Chips and Sprinkles: Gently fold in one cup of chocolate chips or chunks along with three tablespoons of rainbow sprinkles. The batter should be thick and slightly sticky.
Bake to Perfection: Pour the batter into your prepared pan and spread it evenly. Bake for 25-30 minutes or until the edges turn golden brown while the center remains slightly soft. A toothpick should come out with moist crumbs—not wet batter!
Let cool completely before cutting into squares—if you can resist that long!
Now you’re ready to impress your friends with these delightful Fireworks Blondies! Each bite promises bursts of flavor that will leave everyone smiling—and maybe fighting over the last piece!
