A moist, tender crumb cake with a buttery, crumbly topping and colorful rainbow sprinkles inside and out, perfect for celebrations or casual treats.
Use nonpareil sprinkles to prevent color bleeding. Keep butter cold in crumb topping for best crunch. Gently fold sprinkles to maintain vibrant colors. Tent with foil if crumb topping browns too fast. Let cake cool before slicing to prevent crumb topping from falling apart. For gluten-free, use 1:1 gluten-free flour blend. For dairy-free, substitute butter with coconut oil and milk with almond or oat milk.
