# What You 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 (optional)
10 - 1/2 cup rainbow sprinkles (jimmies)

# How To Make:

01 - Preheat the oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving an 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 the 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—do not overmix.
06 - Fold in the white chocolate chips (if using) and most of the sprinkles, reserving a tablespoon for the top.
07 - Spread the batter evenly into the prepared pan. Sprinkle remaining sprinkles over the top.
08 - Bake for 23–26 minutes, or until the 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 the parchment overhang, cut into 16 squares, and serve.

# Expert Tips:

01 -
  • The buttery base keeps these incredibly moist for days unlike so many other bar cookies that dry out
  • They come together in one bowl with minimal fuss perfect for last minute baking needs
02 -
  • Overbaking is the enemy here check at 23 minutes even if they look underdone
  • Jimmies are the only sprinkles that hold their shape nonpareils will dissolve into disappointing dots
03 -
  • Let the melted butter cool slightly so it does not scramble the eggs when you combine them
  • Room temperature ingredients incorporate more evenly creating better texture
