My go to for old school muffins! Located within the Old Airport Road food centre, this stall sells a variety of baked goods. My favourite are the muffins (the Double Chocolate and the Pandan Kaya in particular). If you buy 5, you get one free.
I also like the buns that come in a pack of six that you have to peel apart. They've got red bean, yam, coconut, curry. Yum!
