What You’ll Need
- ½ cup salted butter (room temperature for easy mixing)
- ¾ cup brown sugar (packed for consistent sweetness)
- 1 egg (large, at room temperature)
- 2 teaspoons vanilla extract (pure vanilla for best flavor)
- 1 teaspoon baking powder (ensure it’s fresh for proper rise)
- ½ teaspoon salt (fine sea salt works well)
- 1 ¼ cups all-purpose flour (spooned and leveled for accuracy)
- 1 ½ cups white chocolate chips (or chunks for a melty texture)
- ½ cup rainbow sprinkles (plus 2 tablespoons for garnish)
How to Make Confetti White Chocolate Cookie Bars
- Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with foil and spray with non-stick cooking spray.
- In a stand mixer fitted with the paddle attachment, cream the butter and brown sugar on medium speed for 2 minutes until light and fluffy.
- Add the egg, vanilla, baking powder, and salt. Mix for 1 minute, scraping the sides of the bowl as needed.
- Reduce the speed to low and gradually add the flour, mixing until just combined.
- Stir in the white chocolate chips and ½ cup rainbow sprinkles until evenly distributed.
- Press the dough into the prepared pan, spreading it evenly. Sprinkle the top with the remaining 2 tablespoons of sprinkles.
- Bake for 20-25 minutes, or until the edges are lightly golden brown. A toothpick inserted into the center should come out mostly clean.
- Allow the bars to cool in the pan on a wire rack before cutting into squares. Serve immediately or store airtight at room temperature for up to 3 days.
Fun Topping Ideas to Elevate Your Cookie Bars
Take your Confetti White Chocolate Cookie Bars to the next level with creative toppings! Try drizzling melted white or dark chocolate over the cooled bars for a decadent touch. For a crunchy twist, sprinkle crushed pretzels or chopped nuts on top before baking. If you’re feeling festive, swap the rainbow sprinkles for seasonal ones—think red and green for Christmas or pastels for Easter!
Perfect Pairings: Serving Suggestions
These cookie bars are a crowd-pleaser on their own, but they pair wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream for a dessert upgrade. For a fun party platter, cut them into bite-sized squares and serve alongside other treats like brownies or fruit skewers. Don’t forget a glass of cold milk or a warm cup of coffee to balance the sweetness!
Storage Tips to Keep Them Fresh
Store your cookie bars in an airtight container at room temperature for up to 3 days. If you want to keep them longer, wrap individual bars tightly in plastic wrap and freeze for up to 2 months. When you’re ready to enjoy, simply thaw at room temperature or pop them in the microwave for a few seconds to bring back that fresh-baked warmth.
Quick Time-Saving Tips
Short on time? Use pre-measured ingredients like a bag of white chocolate chips and pre-portioned sprinkles to speed up prep. If you don’t have a stand mixer, a hand mixer or even a sturdy wooden spoon will work just fine. For easy cleanup, skip the foil and use parchment paper instead—it lifts the bars right out of the pan!
Recipe Variations to Mix It Up
Feel free to customize these bars to suit your taste! Swap white chocolate chips for dark or milk chocolate, or add a handful of dried cranberries or chopped macadamia nuts for a different flavor profile. For a gluten-free version, use a 1:1 gluten-free flour blend. The possibilities are endless, so get creative and make this recipe your own!
