Guess it's sugar making middle of ice-cream very soft (7)
I believe the answer is:
suppose
'guess' is the definition.
(I know that guess can be written as suppose)
'it's sugar making middle of ice-cream very soft' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is located in the answer.
'soft' could be 'pp' (musical abbreviation for pianissimo) and 'pp' is present in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
The remaining letters 'sus' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for suppose that I've seen before include "Put forward - imagine" , "Guess" , "Expect" , "Think, assume" , "Judge" .)
