It is best to defrost naturally first.

Quickly frozen cakes should be transferred to a refrigerated environment and allowed to thaw naturally, which will neither damage the appearance nor affect the taste.

Quickly frozen cakes are often heavy oil and cheese cakes, or cakes with layers and decorated surfaces. It is impossible to use heating methods, such as blowing hot air, soaking in warm water or thawing in the microwave. In the current climate, it is not possible to keep it at room temperature. It is likely that the surface has softened and collapsed, but the center is still hard.

So it is correct to transfer it to a refrigerated environment in advance before eating.

After thawing is completed, heat it in the microwave for 3 minutes. Do not use an oven, otherwise the outside will be burnt and the inside will still be cold.
