The spoon keeps its shape because the melting point of the spoon is greater than the temperature of the hot chocolate.

Explanation:

Solids lose there shape and become liquid when they melt. If a spoon maintains its shape when placed in a cup of hot chocolate, it means that the spoon is maintaining its solid shape. This can only happen if the melting point of the spoon is greater than the temperature of the drink. If the spoon didn't keep its shape, it would mean that the melting point of the spoon was less than the temperature of the hot chocolate.
