Tools and Preparation
To create your Fireworks Blondies, you’ll need some essential kitchen tools. Having the right equipment will streamline the process and ensure success!
Essential Tools and Equipment
- Stand mixer or hand mixer
- 9×13-inch baking pan
- Aluminum foil
- Cooking spray
- Mixing bowls
- Spatula
Importance of Each Tool
- Stand mixer or hand mixer: Makes mixing ingredients quick and easy, ensuring everything is well combined.
- Baking pan: A good-quality pan ensures even baking and helps achieve that perfect chewy texture.
Ingredients
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). Line a 9×13-inch baking pan with aluminum foil, leaving some overhang for easy removal later. Spray the foil with cooking spray to prevent sticking.
Step 2: Mix the Dough
In a mixing bowl, combine the unsalted butter and brown sugar. Use a stand mixer or hand mixer to mix until crumbly. Next, add in the large eggs and vanilla extract, mixing until smooth. Gradually incorporate the salt, baking powder, and then sift in the all-purpose flour. Stir until just combined before gently folding in the red, white, and blue M&Ms and patriotic sprinkles.
Step 3: Spread in Pan
Transfer the blondie mixture into the prepared baking pan. Since it’s quite wet, lightly spray your hands with cooking spray to help smooth out the dough evenly across the bottom of the pan. If desired, top with additional M&Ms for decoration.
Step 4: Bake to Perfection
Bake in your preheated oven for about 22-25 minutes. Keep an eye on them; they’re done when they start turning golden but should remain slightly underbaked to maintain their chewiness as they cool down.
Enjoy your festive Fireworks Blondies!

How to Perfect Fireworks Blondies
To ensure your Fireworks Blondies turn out perfectly every time, consider these helpful tips.
- Use Fresh Ingredients – Always use fresh eggs and butter for the best flavor and texture.
- Don’t Overmix – Mix the batter just until combined to keep the blondies soft and chewy.
- Check for Doneness Early – Start checking for doneness at 22 minutes to avoid overbaking; they’re best when slightly underbaked.
- Cool Completely Before Cutting – Allow the blondies to cool in the pan before cutting to prevent them from falling apart.
- Add Extra Mix-ins – Feel free to experiment with different types of M&Ms or nuts for added flavor and texture.
- Store Properly – Keep leftovers in an airtight container at room temperature for up to a week.
Best Side Dishes for Fireworks Blondies
While Fireworks Blondies shine on their own, they can be paired with some delicious side dishes that enhance your dessert experience.
- Fruit Salad – A refreshing mix of seasonal fruits that adds brightness to your dessert spread.
- Cheese Platter – Include cheeses like brie or sharp cheddar to balance the sweetness of the blondies.
- Chocolate Fondue – Dip pieces of blondie into melted chocolate for an indulgent twist.
- Whipped Cream – A dollop of freshly whipped cream can elevate each bite of your blondie.
- Nutty Granola – Sprinkle over your blondies for added crunch and flavor contrast.
- Caramel Sauce – Drizzle warm caramel sauce over the top for an extra decadent touch.
- Yogurt Parfait – Layer with yogurt and fruits for a lighter option that still feels indulgent.
Common Mistakes to Avoid
Making Fireworks Blondies can be a delightful experience, but it’s essential to avoid common pitfalls.
- Using cold ingredients: Always ensure your butter and eggs are at room temperature to achieve a smooth batter.
- Overmixing the batter: Mix just until the ingredients combine. Overmixing can lead to dense blondies instead of soft and chewy ones.
- Not lining the pan properly: A well-lined pan ensures easy removal. Use foil and cooking spray or parchment paper for best results.
- Skipping the cooling time: Let your blondies cool in the pan before cutting. This helps them set better and prevents crumbling.
- Ignoring baking times: Every oven is different; keep an eye on your blondies towards the end of baking to avoid overbaking.
Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 5 days.
- Place parchment paper between layers to prevent sticking.
Freezing Fireworks Blondies
- Wrap each bar individually in plastic wrap, then place in a freezer-safe bag.
- They can be frozen for up to 3 months.
Reheating Fireworks Blondies
- Oven: Preheat to 350°F, then warm for about 10 minutes until soft.
- Microwave: Heat for 10-15 seconds on medium power for a warm treat.
