How to Make Chocolate Meringue Cake
1. Make the mousse.
Fold melted chocolate and butter into Italian meringue, then blend in firmly whipped cream and chill.
2. Prep the chocolate meringue.
Make the French meringue and fold in confectioners' sugar and unsweetened cocoa powder.
3. Shape the cake layers.
Pipe a chocolate meringue spiral onto each of two parchment paper-lined baking sheets.
4. Form the crunchy topping.
Pipe the remaining meringue onto parchment-lined sheets in long sticks, about an inch apart.
5. Cut the meringue sticks.
Use a sharp knife to create 1 1/2- to 2-inch pieces for decorating the cake.
6. Fill the cake.
Using an offset spatula, spread half of the chilled chocolate mousse over one of the meringue spirals.
7. Add another layer.
Place the second round of meringue on top and cover with the remaining chocolate mousse.
8. Finish the dessert.
Arrange the meringue sticks over the top and side and chill. Dust with confectioners' sugar before slicing.
