MB took me to a newish cupcake bakery, Butter Lane, on 7th and A, where you could mix and match your choice of mini cakes with a pretty awesome list of frosting ranging from peanut butter and coconut to strawberry and lemon. I decided on a vanilla cake and lemon icing combo, and it was absolutely divine.
Had I left it at that one visit, I would've gone back to SF telling one and all that Butter Lane is leaps and bounds better than my long-time fave Sugar Sweet Sunshine Bakery.
But alas, I went back for a second visit and found my sophomore cupper didn't meet my expectations—the banana cake was a bit dry, the coconut in the icing tasted a tiny tad raw. Sigh. It was still a good cupcake, but Sugar Sweet remains my number one.
