Announced weekend's desserts (7)
I believe the answer is:
sundaes
'desserts' is the definition.
(sundae is a kind of dessert)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sundaes that I've seen before include "Ice-creams with fruit" , "Ice-cream desserts" , "Cold desserts" .)
