Confetti Cake Blondies with White Chocolate Chips

Soft, chewy blondies that combine the festive spirit of confetti cake with the rich texture of traditional blondies. White chocolate chips add sweetness while colorful sprinkles create a party-ready appearance both mixed throughout and sprinkled on top. The tender crumb comes from creaming butter and sugar, then gently folding in flour and milk. Perfect for birthdays, celebrations, or anytime you want a fun dessert that's easier than making a full cake but just as cheerful and delicious.

FAQ

Can I use milk chocolate chips instead?

Yes, milk chocolate chips work well but will make the blondies sweeter and less vanilla-forward than with white chocolate.

What if I don't have a stand mixer?

Use a hand mixer or mix by hand with wooden spoon, just cream butter and sugar thoroughly for best texture.

How long do these keep?

Store covered at room temperature up to 4 days or refrigerate up to 1 week for best quality and freshness.
