How do I deal with people stealing the delicious baked treats I make for people?

I often make muffins for my family and they eat them all with consulting me or showing any respect to me. I usually bake about 16 muffins for 4 people and my father and mother eat 6 and my brother eats 4 leaving none for me, always within 1 day.

I have tried reasoning with them, and I even tried pouring superglue over 2 of the muffins so I could at least have them but they ate them anyway. Whenever I bring it up my dad calls me ''the muffin maggot'' and they all laugh and tell me I will not stop baking for them because ''sugar pays the rent''.
