The clear difference between salted and unsalted butter is the presence of salt. Mostly unsalted butter is made with 100% cream, salted butter will have some salt added to it. The exact amount of salt present in the butter will depend on the brand. Salted butter also lasts longer in the refrigerator, since salt acts as a preservative.

Aside from salt content, the temperature of your butter also matters when you’re cooking or baking. Too warm and the cake will be too flat or dense. Too cold and you will have chunks of butter in the cake mixture.
