Fold ⅓ cup of the whipped cream into the chocolate mixture, then fold in another ½ cup. Immediately spread the chocolate cream over the moistened cake. Moisten the top of another layer with syrup and place it moist side down on the chocolate cream. Press to level. Moisten the top of the layer.

Moisten the last cake layer and place it moist side down on the cherries and cream; press gently to level. Refrigerate the cake, as well as the remaining whipped cream and cherries, until firm, at least 30 minutes.
Frost the top and sides of the cake with the remaining whipped cream.
