How long does it take for frosting to soften?

Frosting softens at different rates: it can take 1-2 hours at room temperature to soften refrigerated buttercream, but a large batch might need several hours or even overnight, while canned frosting can be warmed in short bursts (10-30 seconds) in the microwave for a quick pourable consistency. Always allow cake to cool before frosting, and let frosted cakes sit out 1-2 hours before serving if refrigerated, as the butter hardens when cold.

It's a flexible guideline, not a strict rule, ensuring enough time for unexpected issues while maintaining quality.
 

Why do bakers wet cake before frosting?

Always trust your senses: if it looks, smells, or tastes off, or shows any signs of mold, discard it.
