Preheat the oven to 180°C . Line a suitable baking pan with parchment paper. Melt the chocolate and butter in a water bath over low heat, stirring occasionally. Add the sugar to the warm chocolate mixture and stir well. Add the eggs one at a time, mixing after each addition until smooth. Stir in the vanilla, a pinch of salt, flour, and cocoa powder. Gently mix with a spatula until the batter is homogeneous. Pour the batter into the prepared pan. Bake for 20–25 minutes – the center should remain slightly moist. Once baked, let the brownie cool completely.
Mascarpone cream: In a bowl, mix the mascarpone with powdered sugar and vanilla until you get a smooth cream. Spread the cream over the cooled brownie and refrigerate for at least 1 hour to set. Before serving, drizzle with Amarena cherry syrup and garnish with Amarena cherries on top.
