Ingredients
For the Blondies
- ½ cup (113g) unsalted butter
- 2 cups (400g) packed brown sugar

- ½ teaspoon salt
- 1 teaspoon baking powder
- 2 cups (248g) all purpose flour

- ½ cup patriotic sprinkles
How to Make Fireworks Blondies
Step 1: Preheat the Oven
Preheat your oven to 350°F. Line your 9×13 inch pan with aluminum foil and spray it generously with cooking spray to prevent sticking.
Step 2: Mix the Wet Ingredients
In a mixing bowl:
1. Combine unsalted butter and brown sugar. Use a stand mixer or hand mixer to beat until crumbly.
2. Add in the eggs and vanilla extract, mixing until smooth.
Step 3: Combine Dry Ingredients
- Mix in the salt, baking powder, then gradually add in the all-purpose flour. Stir until just combined.
- Fold in the red white, and blue M&Ms along with the patriotic sprinkles, ensuring an even distribution throughout the dough.
Step 4: Bake the Blondies
- Spread the dough into the prepared pan using your hands (sprayed with cooking spray) for an even layer.
- Optionally, top with extra M&Ms for added visual appeal.
- Bake in the preheated oven for about 22-25 minutes or until they begin to turn golden at the edges. Remember, it’s best to err on the side of under-baking; they will continue to set as they cool.

Common Mistakes to Avoid
Avoiding common mistakes will ensure your Fireworks Blondies turn out perfectly every time. Here are some tips:
- Not Measuring Ingredients Properly: Accurate measurements are crucial for baking success. Use a kitchen scale for best results, especially with flour and sugar.
- Overmixing the Batter: Mixing too much can lead to tough blondies. Stir until just combined to keep them soft and chewy.
- Skipping the Parchment Paper: Using foil without cooking spray can cause sticking. Always line your pan and spray it well to ensure easy removal.
- Baking Too Long: Overbaking can dry out your blondies. Keep an eye on them and remove them when they just start to turn golden.
- Not Letting Them Cool Properly: Cutting into warm blondies can ruin their texture. Allow them to cool completely in the pan before slicing.
