In this tart, a sinfully rich coffee mousse hides a ganache layer underneath it, giving this tart that layered look we appreciate so much in a well-made latte.
For the ganache layer, place the chocolate in a bowl. Heat the cream to just below a simmer, then pour it over the chocolate. Let it sit for a minute, then gently stir the mixture until the chocolate has melted. Pour this into the cooled crust and spread it evenly across the bottom. Chill while preparing the latte mousse.
