Birthday Cake Stuffed Cookie

Imagine a birthday cake sourdough sugar cookie that's soft, chewy, and slightly tangy from the sourdough—giving it a depth that contrasts beautifully with the sweetness of the sugar cookie base. The edges are lightly crisp, while the center remains tender and dense with a melt-in-your-mouth texture.

Inside, the cookie is generously filled with a luscious cake batter-flavored cream cheese, which is smooth, creamy, and rich with nostalgic notes of vanilla, butter, and sweet funfetti cake. The cream cheese adds a subtle tang that complements both the sourdough and the sugary cookie, creating a balanced, indulgent bite.
