So, which one should you use? It depends on your mood, your patience, and your sugar tolerance. Hosting a party? Go with American buttercream. Showing off? Swiss meringue. Feeling lazy? Glaze. Craving elegance? Ganache.
Just remember: frosting is never the enemy. It’s the reason we eat the cake. The cake is just a vehicle. So grab a spoon, make a mess, and frost everything in sight. Your coffee is waiting. Go conquer that butter.
