I had read about this place on happycow, and here's my Yummy Cupcakes review.
I walk by this cupcake shop from time to time. It's located in the 3rd Street Promenade shopping area in downtown Santa Monica. Finally I went it and bought a vegan one.
On the day that I visited, the 2 vegan flavors were apple and vanilla. I opted for the apple. Cost $3.50 out-the-door.
The cake part was nice, spongy, and moist - I liked that. The frosting, however, was much too sweet for me personally. But I guess others like very sweet.
The space and decor at this location is very basic, more like a kitchen than a shop.
Cons: mostly dairy
