"After eating the cakes I felt satisfied yet my mum offered me some more"
Does your mum know you are trying to limit your cake consumption? If you ask her to please not offer you more than one piece, explaining that "having to say no" is really so much more difficult than walking away.... would she support you and abide by your request?
Or would she still try to feed you?
If she agrees to help you - there's a good solution.
If she keeps on offering, take it and secretly throw it away, and don't feel the least bit guilty about it.
