Buttery bars with sprinkles and white chocolate for a colorful St Patricks celebration.

# What You’ll Need:

→ Dry Ingredients

01 - 2 cups all-purpose flour
02 - 1/2 teaspoon baking powder
03 - 1/4 teaspoon salt

→ Wet Ingredients

04 - 3/4 cup unsalted butter, melted and cooled
05 - 1 cup granulated sugar
06 - 1/2 cup light brown sugar, packed
07 - 2 large eggs
08 - 2 teaspoons pure vanilla extract

→ Mix-Ins

09 - 3/4 cup white chocolate chips
10 - 1/2 cup rainbow sprinkles, divided

# Method:

01 - Preheat the oven to 350°F. Line a 9x9-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
03 - In a large bowl, whisk melted butter, granulated sugar, and brown sugar until smooth. Add eggs and vanilla extract; whisk until fully combined.
04 - Gradually fold the dry ingredients into the wet ingredients with a spatula, mixing until just combined.
05 - Stir in the white chocolate chips and 1/3 cup of the rainbow sprinkles.
06 - Spread the batter evenly into the prepared pan. Sprinkle the remaining sprinkles over the top.
07 - Bake 25–28 minutes, or until the edges are golden and a toothpick inserted into the center comes out mostly clean.
08 - Cool completely in the pan on a wire rack before slicing into bars.

# Expert Advice:

01 -
  • They come together in less than an hour, so you can bake them while your coffee's still warm.
  • The white chocolate and rainbow sprinkles make them look showstopping without any fancy technique.
  • They're soft enough to bite through but sturdy enough to grab and eat with one hand at a party.
02 -
  • Don't skip cooling the melted butter before adding eggs, or you'll end up with scrambled egg bits in your batter.
  • The parchment paper overhang is your secret weapon for pulling these out cleanly and whole, so don't skip it.
03 -
  • Use a sharp knife dipped in hot water and wiped clean between cuts for neat, clean bars without crumbs falling everywhere.
  • If you want extra festivity, melt some white chocolate and drizzle it across the cooled bars before serving.
