Last weekend I ate at Alcove in Silverlake, which is known as a great bruch and lunch spot, but I remember it for it's desserts.
They have an amazing bakery section with massive cakes.
Black and White Mouse Cake - This was insane! The top half was white chocolate mouse that must have had cream cheese in it, it was so light an fluffy and tasted like cheese cake. Below that was a milk chocolate mouse, followed by a chocolate cake bottom. The outside was a dark ganache with white chocolate flakes.
