Finally had a chance to stop by Leda's bake shop in Sherman Oaks(next to Senor Fred's on Ventura Blvd).
I had a mini cupcake w/Lemon curd inside w/a lemon mascarpone cheese on top. It was really tasty. Great lemony flavor and very moist. cost: $1.50
they also had other flavors:
chocolate chocolate chocolate
chocolate peanut butter
and the other 2 which I can't remember, had some sort of blood orange filling/mascarpone cheese.
they also have kids cupcakes.
cute shop and very friendly.
