1) Dissolve instant espresso in hot water in a medium sized bowl.

2) Add the Nutella and Kahlua, beating until smooth.

3) In a mixer, whip the whipping cream until it forms stiff peaks. Gently fold the nutella mixture into the whipped cream until the color is uniform.

4) Divide mousse into serving glasses- martini glasses work great!

5) Add toasted hazelnuts, chocolate shavings, and pirouette cookies for decoration
