Which frozen dessert melts the slowest ice-cream frozen yogurt or sherbet?

Ice cream typically melts the slowest among the three frozen desserts - ice cream, Frozen Yogurt, and sherbet - due to its higher fat content. Fat acts as an emulsifier, which helps to stabilize the mixture and slow down the melting process. Frozen yogurt and sherbet have lower fat content and higher water content, causing them to melt faster than ice cream.
