Donates rice crackers, being kind (11)
I believe the answer is:
considerate
'being kind' is the definition.
(similar in meaning)
'donates rice crackers' is the wordplay.
'crackers' is an anagram indicator (informal term for mad).
'donates'+'rice'='donatesrice'
'donatesrice' anagrammed gives 'CONSIDERATE'.
(Other definitions for considerate that I've seen before include "Showing concern for the feelings of others" , "Kind" , "Mindful of others' well-being" , "Showing care" , "Unselfish" .)
