Rainbow Cookies

Since I was little, rainbow cookies have always been one of my favorite treats! In NY, almost every deli sells them, but its hard to find a really good one. I got these from a deli near my house and they are actually really good, but the best one's I've had are still from the Quogue Market in Long Island. They can go wrong and taste cheap if made with bad chocolate, but when you find a good one, they are amazing! Something about the cake with jelly and chocolate makes for a perfect combination. Anyone know where to find a good Rainbow Cookie in LA? The hunt is on!
