Once Upon A Time is a bakery at 14 Lorong 32 Geylang, Singapore 398277, in Geylang. It holds a Google rating of 5.0 from 6 reviews. Customers say the macadamia and sea salt brownie tasted fresh and not overly sweet, and that collection is quick, though it is made through a small window at the back.
Its website says the bakery has no fixed menu. New bakes replace old ones, and each one is sold for a limited time before it is retired. Its signature line, WTFudge, began as a home-baked order and grew into a shop. Orders go through the online store only, and collection is at the back door. Email and phone are not used for normal orders, except for bulk or corporate orders.
Geylang is a busy neighbourhood with many small bakeries, which makes this one a good place to try a limited bake that may not be around for long.
