Yellow cake mix and butter golden cake mix are not the same, although they share some similarities. Yellow cake mix is typically made with whole eggs and all-purpose flour, giving it a yellow color and a richer, buttery flavor. Butter golden cake mix, on the other hand, specifically highlights a buttery flavor. It may contain added butter flavoring or butter ingredients, which can make it taste more buttery compared to a standard yellow cake mix. While both can be used for baking, butter golden cake mix is chosen for its distinct buttery taste, while yellow cake mix has a more general flavor profile.
