Ingredients
Fireworks Blondies – this EASY blondie recipe is the BEST EVER COOKIE BAR! It’s so soft and perfect with any additions, but especially with 4th of July M&Ms and sprinkles!
For the Blondies
- ½ cup (113g) unsalted butter
- 2 cups (400g) packed brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- ½ teaspoon salt
- 1 teaspoon baking powder
- 2 cups (248g) all purpose flour
- 2 cups red white and blue M&Ms
- ½ cup patriotic sprinkles
How to Make Fireworks Blondies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Prepare a 9×13-inch baking pan by lining it with foil or parchment paper. Don’t forget to spray it well with cooking spray to prevent sticking.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine the unsalted butter and brown sugar. Use your stand or hand mixer on medium speed until it’s crumbly. Next, add in the eggs and vanilla extract, mixing until smooth.
Step 3: Combine Dry Ingredients
Incorporate the salt, baking powder, and then gradually mix in the all-purpose flour. Stir gently until just combined. Finally, fold in the colorful M&Ms and patriotic sprinkles, ensuring they’re evenly distributed throughout the batter.
Step 4: Spread in Pan
Spread the blondie mixture into your prepared pan. Since the batter is wet, it’s helpful to spray your hands with cooking spray before smoothing it down for an even layer. Feel free to sprinkle extra M&Ms on top for decoration.
Step 5: Bake
Place the pan in your preheated oven. Bake for about 22-25 minutes until they start turning golden around the edges. Remember, it’s better to slightly underbake them; they’ll continue cooking as they cool down. Enjoy your delicious Fireworks Blondies!
How to Serve Fireworks Blondies
Fireworks Blondies are a delightful treat that can be enjoyed in many ways. Whether at a party or a cozy family gathering, here are some creative serving suggestions to elevate your dessert experience.
With Ice Cream
- Vanilla Ice Cream: A classic pairing, the creamy texture of vanilla ice cream complements the chewy blondies perfectly.
- Chocolate Ice Cream: For chocolate lovers, this combo adds richness and depth to each bite.
Drizzled with Sauce
- Caramel Sauce: Warm caramel sauce drizzled over the top adds sweetness and an indulgent touch.
- Chocolate Sauce: A drizzle of chocolate sauce creates a decadent finish that enhances the flavors of the blondies.
Topped with Fresh Fruit
- Berries: Strawberries, blueberries, or raspberries add a fresh burst of flavor and a pop of color.
- Banana Slices: Ripe banana slices provide natural sweetness and pair wonderfully with the blondie’s flavors.
Garnished with Whipped Cream

How to Perfect Fireworks Blondies
To achieve the best results when making Fireworks Blondies, consider these helpful tips. They will ensure your blondies turn out perfectly every time.
- Use Fresh Ingredients: Ensure your baking ingredients are fresh for optimal flavor and texture.
- Don’t Overmix: Mix just until combined to keep blondies soft and chewy; overmixing can lead to tough bars.
- Check for Doneness Early: Since they continue cooking after you take them out of the oven, check them at the lower end of the baking time.
- Cool Completely Before Cutting: Let them cool fully before slicing; this helps maintain their shape and makes cutting easier.
- Store Properly: Keep leftovers in an airtight container at room temperature for up to one week to retain freshness.
Best Side Dishes for Fireworks Blondies
Fireworks Blondies make an exciting dessert on their own, but they can also be complemented by various side dishes. Here are some delicious options you can serve alongside them.
- Fruit Salad: A refreshing mix of seasonal fruits balances the sweetness of blondies wonderfully.
- Cheese Plate: A selection of cheeses provides a savory contrast that enhances the overall dessert experience.
- Nutty Trail Mix: This crunchy mix offers texture and flavor balance when paired with soft blondies.
- Coffee or Tea: A warm beverage like coffee or tea complements dessert nicely while inviting guests to linger.
- Popsicles: Cool popsicles offer a fun contrast in temperature and can add variety to your dessert spread.
- Mini Cupcakes: These bite-sized treats provide additional flavors while keeping portions manageable.
Common Mistakes to Avoid
Making Fireworks Blondies can be simple, but avoiding common mistakes will ensure your dessert shines. Here are some pitfalls to watch out for:
- Incorrect Oven Temperature: Always preheat your oven to 350°F. If the temperature is off, your blondies may bake unevenly or become dry.
- Overmixing the Batter: Mixing too much after adding flour can lead to tough blondies. Mix just until combined for a soft texture.
- Not Using Parchment Paper: Skipping parchment paper can result in sticky blondies that stick to the pan. Use foil and spray with cooking spray for easy removal.
- Ignoring Baking Time: Keep an eye on your blondies as they bake. They should be golden but slightly underbaked for a chewy texture.
- Using Old Ingredients: Fresh ingredients make a big difference. Check your baking powder and flour dates to ensure optimal freshness.
Storage & Reheating Instructions
Refrigerator Storage
- Duration: Store in the refrigerator for up to 1 week.
- Containers: Place in an airtight container to keep them fresh.
Freezing Fireworks Blondies
- Duration: Freeze for up to 3 months.
- Containers: Wrap tightly in plastic wrap, then place in a freezer bag or airtight container.
Reheating Fireworks Blondies
- Oven: Preheat to 350°F, place blondies on a baking sheet, and heat for about 10 minutes.
