Mini Birthday cake

<p><strong>Inspired by the Classic Birthday Layer Cake</strong></p><p>You know that moment when someone brings out a birthday cake and the whole room lights up? That's the energy of this cookie. A soft, vanilla-forward base is loaded with rainbow sprinkles throughout - not just on top, because the fun should be in every single bite. White chocolate chips add a creamy sweetness, and the whole thing bakes up thick and pillowy, like the best slice of birthday cake you've ever had, but in cookie form.</p><p>It's celebratory, it's joyful, and it's proof that you don't need a special occasion to have cake. Or a cookie. Or both.</p>
