How to Make Fireworks Blondies
Preheat Your Oven: Set your oven to 350°F (175°C). Prepare an 8×8-inch baking dish by greasing it lightly with nonstick spray or lining it with parchment paper.
Melt the Butter: In a medium saucepan over low heat, melt unsalted butter until just melted. Remove from heat and let it cool slightly.
Add Sugars and Mix Well : Stir in both brown sugar and granulated sugar until well combined. The mixture should look glossy and smooth.
Add Eggs and Vanilla : Mix in large eggs one at a time, ensuring each one is fully incorporated before adding the next. Add pure vanilla extract for flavor harmony.
Combine Dry Ingredients : In a separate bowl, whisk together all-purpose flour, baking powder, and salt. Gradually incorporate this dry mix into your wet mixture until just combined.
Add Sprinkles : Gently fold in colorful sprinkles using a spatula. Be careful not to overmix; you want those vibrant colors scattered throughout without losing their charm.
Bake the Blondies : Pour batter into prepared baking dish and spread evenly. Bake in preheated oven for about 20-25 minutes or until golden on top but still slightly soft in the middle.
Once baked, let them cool completely before slicing into squares. Enjoy these delicious Fireworks Blondies at any gathering or just because you deserve something sweet!
