Why You’ll Love This Recipe

• 
  Colorful and fun: Rainbow sprinkles transform these brownies into a party-ready treat perfect for any occasion.
• Easy way to elevate brownies: With a little bit of extra vanilla and white chocolate chips, these brownies go from classic to show-stopping in no time.
• Perfect chewy texture: The brown butter base and crackly top create the ideal balance of fudgy and soft, making them irresistible.

Ingredients

• Unsalted butter: Browning the butter adds depth and nuttiness—don’t skip this step for a rich, caramelized flavor.
• Granulated sugar and brown sugar: These two work together to create the right amount of sweetness and chewy texture.
• Vanilla extract: A key ingredient for enhancing that funfetti cake flavor—use pure vanilla for the best taste.
• All-purpose flour: Classic enriched bleached flour gives structure while keeping the texture soft.
• Baking powder: Just a little bit ensures the brownies have a slight lift without being cakey.
• Salt: Balances the sweetness and brings out the flavors of the brown butter and sprinkles.
• White chocolate chips: Adds creamy sweetness and a fun contrast to the fudgy brownie texture.
• Rainbow sprinkles: Choose jimmies for vibrant pops of color that hold up beautifully during baking.
• Eggs and egg yolk: Room temperature eggs ensure smooth mixing and a cohesive batter.

Ingredient Substitutions

• White chocolate chips → Candy-coated chips: Add a pop of color and crunch with candy-coated chips.
• All-purpose flour → Gluten-free flour: Substitute a 1:1 gluten-free blend for a celiac-friendly treat.

Ingredient Additions

• Chocolate ganache drizzle: Add a layer of fudgy brownie-style decadence by drizzling ganache over cooled brownies.
• Almond extract: A tiny splash can add a subtle, nutty flavor that pairs perfectly with white chocolate.

Step by Step Instructions

Brown the Butter: In a large saucepan, melt 1 cup of unsalted butter over medium heat, stirring frequently. Continue cooking until the butter foams and turns golden brown with a nutty aroma. Remove the saucepan from the heat and let it cool for about 5 minutes.

Make the Batter: Add 1 1/4 cups granulated sugar and 3/4 cup light brown sugar directly into the saucepan. Stir until the sugars are fully dissolved in the warm butter. Add 2 teaspoons of vanilla extract and mix well.

Add 3 large eggs and 1 egg yolk, one at a time, whisking quickly after each addition. This will ensure the eggs don’t scramble in the warm butter-sugar mixture.

Sprinkle 1 1/4 cups all-purpose flour, 1/4 teaspoon baking powder, and 1/2 teaspoon salt over the wet mixture in the saucepan. Stir until just combined, being careful not to overmix.

Gently fold in 3/4 cup white chocolate chips and 1/2 cup rainbow sprinkles. Make sure the batter has cooled slightly before adding the sprinkles to prevent bleeding.

Bake: Pour the batter into a parchment-lined 9×13-inch baking dish and smooth the top. Sprinkle additional sprinkles evenly over the top.

Bake at 350°Fahrenheit (175°Celsius) for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Cool and Serve: Let the brownies cool completely in the pan before slicing to keep the layers neat and the sprinkles intact.

Expert Tips and Notes

• Brownie layer perfection: Baking dish size matters—use a 9×13-inch pan for evenly baked brownies with a chewy center.
• Cool completely: Allow the brownies to cool fully before slicing to keep the fun sprinkles intact and avoid smudging the layers.
• Parchment paper lining: For an easy way to remove brownies from the pan, line it with parchment paper, leaving overhang on the sides.

Serving Suggestions

• Celebrate with ice cream: Top a warm brownie with a scoop of vanilla ice cream and extra sprinkles for the ultimate dessert. You could also do this with my m&m brownies!
• Party platter star: Arrange the brownies on a tray with other cookie bars and funfetti blondies for a colorful dessert spread.

Storage Instructions

• Short-term: Store in an airtight container at room temperature for up to 4 days to maintain their chewy texture.
• Long-term: Freeze brownies in a freezer-safe bag or wrapped in parchment paper for up to 3 months. Thaw at room temperature before serving.
