Ingredients
To make these delicious Fireworks Blondies, you will need the following ingredients:
- 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. This step is crucial for getting those blondies perfectly baked.
Step 2: Prepare Your Baking Pan
Line a 9×13” pan with foil and spray it well with cooking spray. This will prevent sticking and make cleanup easier.
Step 3: Mix Wet Ingredients
In a large bowl, mix the unsalted butter and brown sugar using either a stand mixer or hand mixer until crumbly. Then add in the eggs and vanilla extract, mixing until smooth.
Step 4: Add Dry Ingredients
Stir in the salt, baking powder, then gradually add the all-purpose flour. Mix until just combined.
Step 5: Fold in M&Ms and Sprinkles
Gently stir in the red white, and blue M&Ms along with the patriotic sprinkles. Ensure they are evenly distributed throughout the mixture.
Step 6: Spread into Pan
Spread the mixture into your prepared pan. Since it may be wet, spray your hands with cooking spray to help smooth out the dough evenly. Optionally, top with extra M&Ms for added decoration.
Step 7: Bake
Bake in your preheated oven for about 22-25 minutes until they start to turn golden. Remember to err on the side of underbaking; they will continue to cook as they cool down.
Enjoy your delicious Fireworks Blondies as a delightful treat any time of year!

How to Perfect Fireworks Blondies
Getting the perfect texture and flavor in your Fireworks Blondies is essential. Follow these tips for outstanding results.
- Use Room Temperature Ingredients: Ensure butter and eggs are at room temperature for a smoother batter.
- Don’t Overmix: Mix just until combined to keep blondies soft and chewy; overmixing can make them dense.

Common Mistakes to Avoid
When making Fireworks Blondies, avoiding common pitfalls can ensure your dessert turns out perfectly every time. Here are some mistakes to watch out for:
- Using cold ingredients – Cold butter and eggs can lead to uneven mixing. Always bring your butter and eggs to room temperature before starting.
- Not measuring flour correctly – Too much flour can make your blondies dry and dense. Use the spoon-and-level method for accurate measuring.
- Overmixing the batter – Overmixing can result in tough blondies. Mix just until the ingredients are combined for a softer texture.
- Ignoring baking times – Every oven is different. Keep an eye on your blondies; remove them when they’re slightly underbaked for the best texture.
- Skipping the cooling process – Cutting into hot blondies can cause them to crumble. Allow them to cool in the pan before slicing for clean edges.
Storage & Reheating Instructions
Refrigerator Storage
- Store Fireworks Blondies in an airtight container.
- They will stay fresh for up to 5 days in the fridge.
Freezing Fireworks Blondies
- Wrap individual bars in plastic wrap, then place them in a freezer bag.

Reheating Fireworks Blondies
- Oven – Preheat to 350°F and warm for about 10 minutes for a freshly baked taste.
- Microwave – Heat on medium power for 10-15 seconds until warm; great for a quick treat!

Frequently Asked Questions

Can I add nuts to my Fireworks Blondies?

How do I know when my Fireworks Blondies are done?
