Hypothesised issue for girl providing treacle? (7,7)

I believe the answer is:

electra complex

'hypothesised issue for girl' is the definition.
(Freudian concept supposedly affecting daughters)

I don't understand how the rest of the clue works.

(Other definitions for electra complex that I've seen before include "girl's sexual attraction" , "daughter sticks to father?" .)

I've seen this clue in The Guardian.
