How to Make Fireworks Blondies
Phase 1 – Prep
STEP 1. Preheat oven. Set your oven to 350 degrees F for optimal baking.
STEP 2. Prepare the baking pan. Line a 9×13 inch pan with foil and spray well with cooking spray.
STEP 3. Mix butter and sugar. Beat unsalted butter and packed brown sugar together with a stand or hand mixer until crumbly.
STEP 4. Add eggs and vanilla. Mix in the eggs and vanilla extract until smooth.
Phase 2 – Cook
STEP 5. Combine dry ingredients. Mix in salt, baking powder, and then gradually add flour.
STEP 6. Add M&Ms and sprinkles. Stir in red, white, and blue M&Ms along with patriotic sprinkles.
STEP 7. Spread in pan. Transfer the batter to the prepared pan, smoothing it with your hands—spray hands with cooking spray for best results.
STEP 8. Top with M&Ms. Optionally add extra M&Ms for visual appeal.
STEP 9. Bake blondies. Place in the oven and bake for about 22-25 minutes until they start turning golden.
Phase 3 – Serve
STEP 10. Cool and store. Allow blondies to cool before cutting. Err on the side of under baking; they will finish setting as they cool.
For best results, bake in a metal pan. Store in an airtight container for up to 4 days or freeze for up to 3 months.
Why This Recipe Works
This recipe achieves a perfect texture by balancing the moisture from the butter and brown sugar with the structure provided by the flour and eggs. The inclusion of M&Ms gives a satisfying crunch, while the sprinkles add a festive touch. Additionally, the baking time is optimized to ensure a chewy center that complements the slight crispness of the edges. Using brown sugar instead of granulated sugar adds a depth of flavor, providing that rich caramel-like sweetness. Together, these elements converge to create a delicious treat that’s not only good-looking but also unforgettable in taste.
Pro Tips
For best results, make sure your butter is softened to room temperature so it blends easily with the sugars. When measuring the flour, spoon it into the measuring cup and level it off with a knife to avoid overpacking. If you’d like an extra chewy texture, slightly underbake the blondies; they’ll continue to cook after being removed from the oven. To make the blondies easier to cut, allow them to cool completely, or even refrigerate them for a little while before slicing. Finally, don’t hesitate to experiment with the mix-ins—you can tailor the blondies to suit your tastes or the season!
