In a large bowl, whisk together the flour, baking powder, and vanilla sugar.
Cream together the butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition.
Mash the chestnut puree with a fork, then stir in the lemon juice and zest.
Gradually add the flour mixture to the butter-egg mixture, alternating with the milk, until just combined.
Pour the batter into a greased and floured cake pan and spread evenly.
Bake in a preheated oven at 350°F (180°C) for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool completely in the pan before carefully inverting it onto a serving plate.
Before serving, garnish with lemon slices or powdered sugar, if desired.
