Cream together the butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition.
Sift together the flour and baking powder, then stir in the ground walnuts. Gradually add this to the butter-egg mixture until just combined.
Stir in the chestnut puree until the batter is smooth and creamy.
Pour the batter into a greased and floured cake pan and bake in a preheated oven at 350°F (180°C) for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
While the cake is cooling, prepare the frosting: whip the heavy cream with powdered sugar until stiff peaks form. Stir in the vanilla extract.
Once the cake has cooled completely, slice it in half horizontally. Spread the vanilla whipped cream filling evenly over the bottom layer. Top with the other cake layer.
Frost the top of the cake with the remaining whipped cream, smoothing it out evenly. Decorate the top with chocolate shavings and walnut pieces for added visual appeal.
Refrigerate the cake for at least 2 hours to allow the flavors to meld and the frosting to set.
