Dessert made from date with some fried bananas (10)

'dessert' is the definition.
(I know that Semifreddo is a type of frozen dessert)

'date with some fried bananas' is the wordplay.
'date' becomes 'd' (abbreviation e.g. dob - date of birth).
'with' means one lot of letters go next to another.
'bananas' indicates anagramming the letters (bananas can informally mean crazy).
'some'+'fried'='somefried'
'd' put after 'somefried' is 'somefriedd'.
'somefriedd' with letters rearranged gives 'SEMIFREDDO'.
