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.
