These thick, soft Funfetti birthday cake cookies are a homemade copycat of the famous Crumbl bakery treat, bursting with colorful sprinkles and classic birthday cake flavor. Easy to make with pantry staples, they’re perfect for celebrations or whenever you need a little sprinkle-filled joy.
Chill the dough for thick, bakery-style cookies. Use rainbow jimmies (not nonpareils) to prevent color bleeding. Don’t over-mix after adding flour. For extra-thick cookies, stack two smaller dough balls. Let cookies cool before frosting. Store in an airtight container for up to 4 days or freeze unfrosted cookies for up to 2 months.
