Cake My Day features vanilla cake batter ice cream with vanilla cake pieces, buttercream frosting, and raspberry swirls.
Unlike the chain's regular flavors, you won't be able to locate the new flavor with their online flavor locator and will have to try and find it the old fashioned way. From what I understand, the ice cream gets sent to a distributor from the factory and stores decide whether to buy from the distributor (I guess they don't track it because of the short duration).
