Cakes made by females in part of UK (7)
I believe the answer is:
Here is my best explanation:
'cakes' is the definition.
(waffle is a kind of cake)
'females in part of uk' is the wordplay.
'females' becomes 'ff' (I've seen this in other clues).
'in' indicates putting letters inside.
'part of uk' becomes 'wales' ('Wales' is part of 'uk').
'ff' put inside 'wales' is 'WAFFLES'.
'made by' acts as a link.
(Other definitions for waffles that I've seen before include "Talks vaguely", "doesn't avoid 27 [VERBIAGE]", "Cakes" and "Talks imprecisely".)
