Cheerful, buttery blondies with rainbow sprinkles perfect for spring celebrations.

# What You'll Need:

→ Dry Ingredients

01 - 1 1/2 cups all-purpose flour
02 - 1/2 teaspoon baking powder
03 - 1/2 teaspoon salt

→ Wet Ingredients

04 - 1/2 cup unsalted butter, melted and slightly cooled
05 - 1 cup light brown sugar, packed
06 - 1 large egg
07 - 1 large egg yolk
08 - 2 teaspoons pure vanilla extract

→ Add-Ins

09 - 1/2 cup white chocolate chips
10 - 1/2 cup rainbow sprinkles (jimmies)

# How-To Steps:

01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing overhang for easy removal.
02 - In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
03 - In a large bowl, whisk melted butter and brown sugar until smooth and glossy.
04 - Add the egg, egg yolk, and vanilla extract. Whisk until fully incorporated.
05 - Gently fold the dry ingredients into the wet mixture using a spatula until just combined. Avoid overmixing.
06 - Fold in white chocolate chips and most of the sprinkles, reserving 1 tablespoon for topping.
07 - Spread batter evenly into prepared pan. Sprinkle remaining sprinkles over the top.
08 - Bake for 23-26 minutes until edges are set and a toothpick inserted in the center comes out with a few moist crumbs.
09 - Let cool completely in the pan on a wire rack. Lift out using parchment overhang, cut into 16 squares, and serve.

# Expert Tips:

01 -
  • They taste like a celebration but come together in under an hour
  • The extra egg yolk makes them fudgy in the center while staying slightly crisp at the edges
02 -
  • Nonpareil sprinkles will bleed color into your batter creating strange gray streaks so stick to the long rod shaped jimmies
  • Letting the melted butter cool slightly prevents the eggs from scrambling when they hit the warm sugar
03 -
  • Room temperature eggs incorporate more easily into the warm butter mixture
  • These freeze beautifully if you wrap individual squares in plastic and foil
