Earl Grey Cake with honey cream frosting. Without blowing my own horn too much, I have to tell you this Earl Grey "London Fog" cake is a devastating beauty. With two layers of Earl Grey infused sponge cake and a drizzle of Earl Grey syrup, soft billowy whipped vanilla cream and a canopy of edible flowers it's a surprisingly easy show stopper. It was inspired by one of the blog's most popular cakes: the chai spiced cake. It made me wonder why there were so many coffee cakes but what about tea cakes? Or cakes with actual tea in them.
