Ganache and Ganache Frosting are made with the same ingredients, but using different ratios of cream to chocolate. Ganache usually refers to a glaze that is drizzled over baked goods and ganache frosting refers to a spreadable frosting or filling for baking goods. Allowing ganache to cool in the fridge will make it thicker (much like the frosting), but it also causes it to lose its “drippy” quality that ganache is known for.
