Coffee can make you macho! (5)
I believe the answer is:
mocha
'coffee' is the definition.
(type of coffee drink)
'can make you macho' is the wordplay.
'can make you' indicates anagramming the letters.
'macho' anagrammed gives 'MOCHA'.
(Other definitions for mocha that I've seen before include "Dark brown" , "It may end up as grounds" , "Coffee flavour" , "Deep brown; a fine coffee" , "Strong dark coffee" .)
