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 Base

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

For Decoration

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). Line a 9×13-inch pan with aluminum foil to ensure easy removal later. Spray the foil well with cooking spray to prevent sticking.

Step 2: Mix the Batter

In a mixing bowl, combine unsalted butter and brown sugar. Use either a stand mixer or hand mixer to beat them together until crumbly. Add in eggs and vanilla extract, mixing until smooth. Gradually incorporate salt, baking powder, then fold in all-purpose flour. Finally, stir in the festive M&Ms and sprinkles, making sure they are evenly distributed.

Step 3: Spread into Pan

Carefully spread the mixture into your prepared pan. Since the batter is wet, it’s helpful to spray your hands with cooking spray before smoothing down the dough evenly in the pan. For an extra touch, top with additional M&Ms if desired.

Step 4: Bake

Place the pan in your preheated oven and bake for about 22-25 minutes. Keep an eye on them; you want them to turn golden but slightly underbaked. They will continue cooking as they cool down outside of the oven. Enjoy your delicious Fireworks Blondies once they have cooled!

How to Perfect Fireworks Blondies

Perfecting your Fireworks Blondies is all about attention to detail. Here are some tips to ensure they turn out deliciously every time.

Use room temperature ingredients – Allow butter and eggs to reach room temperature for better mixing.
Don’t overmix – Mix until just combined to keep the blondies soft and chewy.
Check for doneness – They should be golden on the edges but slightly underbaked in the center for that perfect texture.
Cool completely – Let them cool in the pan before cutting for cleaner edges.
Add more mix-ins – Feel free to customize with nuts or chocolate chips for added flavor and texture.

Best Side Dishes for Fireworks Blondies

Fireworks Blondies shine as a dessert on their own, but pairing them with side dishes can create a delightful spread. Here are some great options to consider.

Fruit Salad – A light and refreshing mix of seasonal fruits balances the sweetness of blondies.
Charcuterie Board – An assortment of cheeses, meats, and crackers provides a savory contrast.
Veggie Platter – Crunchy vegetables paired with hummus offer a healthy option alongside rich desserts.
Ice Cream Bar – Set up an ice cream station so guests can create their own sundaes with toppings galore.
Cheese Cake Bites – Mini cheesecake bites bring creamy indulgence that pairs well with the chewy blondie texture.
Brownie Bites – For those who love variety, mini brownies provide another chocolaty treat option.

Common Mistakes to Avoid

Making Fireworks Blondies is simple, but a few common mistakes can lead to less-than-perfect results. Here are some pitfalls to watch out for:

Skipping the Preheating: If you don’t preheat your oven, your blondies may not bake evenly. Always ensure your oven is at 350°F before placing the batter inside.
Using Cold Ingredients: Cold butter or eggs can lead to a lumpy batter. Allow them to come to room temperature for a smoother mixture.
Overmixing the Batter: Overmixing can make your blondies tough instead of chewy. Mix just until combined for the best texture.
Ignoring Bake Time: Baking for too long can result in dry blondies. Start checking around 22 minutes and remove them when they’re just golden.
Not Lining the Pan Properly: If you skip lining or greasing the pan, it will be difficult to remove the blondies later. Always line with foil and spray with cooking spray.
