Notes
I baked the above qty as two cakes, one in a 10 inch bundt pan and another in a 7 inch round tin. The baking time for bundt cake was 45-50 mins and for round cake was 35-40 mins. I used salted butter for the cake and unsalted butter for the icing. You can use unsalted butter for cake too, if you wish. I added only 1 cup icing sugar for the frosting and also added 1/4 tsp of salt to the icing. For the mascarpone cream - I used around 100 gms of mascarpone cheese and 1/2 cup whipping cream (whip till soft peaks form), 1 - 2 tbsp icing sugar, 1/2 tsp vanilla essence and 1 vanilla bean. Whisk together mascarpone cheese, vanilla bean seeds , essence and icing sugar. gently fold in the whipped cream. You can bake the cake and make the sauce and mascarpone cream (if making) one - two days in advance. Store the cake @ room temp and icing and cream in the fridge. Make sure you reheat the sauce in micro and pour / drizzle over the cake while serving. The cake with the sauce can be stored at room temp for one - two days, unless you live in a humid place.
