left-to-right:

A dessert spoon is a spoon designed specifically for eating dessert. Similar in size to a soup spoon (intermediate between a teaspoon and a tablespoon) but with an oval rather than round bowl, it typically has a capacity around twice that of a teaspoon.

By extension, the term "dessert spoon" is used as a cooking measure of volume, usually of 10 ml or 13 fl oz.
