*To toast almonds, place them on cookie sheet and shake to form a uniform thin layer. Bake at 350°F about 7 minutes or until they are just golden. For even toasting, shake the pan once or twice during baking.
Mousse is French for froth or foam. Sweet mousses are cooked custards made with fruit puree or chocolate, gently combined with beaten egg whites and chilled. The almond-flavored chocolate mousse in this cake takes an easy, quick shortcut — it's simply melted chocolate folded into whipped cream.
Bake the cake in advance, let it cool, cut as directed in the recipe and wrap tightly with plastic wrap and foil. Seal it in a food-storage freezer plastic bag and freeze it up to three days. Prepare the mousse one day in advance. Early in the day, assemble the frozen cake with the chilled mousse; cover and refrigerate. Remove the dessert from the refrigerator one hour before serving.
This pretty cake only looks complicated; it's actually a snap to put together. It looks elegant on the dessert table and it serves a crowd.
