Preheat oven to 350. Spray a 10 inch, a 8 inch and a 6 inche cake pans with bakers spray
In a bowl whisk together flour, baking powder and salt
In another bowl beat butter and sugar until light and fluffy
Add flour mixture alternating with milk beating just until smooth then add eggs and bea just until combined
Pour the batter into the prepared o ans so that they all are the same height about 1 inch in each oan. You want the layers about the same height. Note my 10 inch pan seems to big but it's just because of its high sides
Bake until a toothpick comes out just clean. The times will be slightly different for each pan. The 6 inch will take about 10 minutes, the 8 inch about 11 to 13 minutes and the 10 inch about 13 to 16 minutes. Cool on racks in pans 10,inutes then remove from pans to cool completely before frosting

In a bowl beat nutella and marscapone until smooth
In another large bowl beat cream until it starts to thicken, add sugar and vanilla and beat until it holds its shspe
Fold nutella/marscapone into whipped cream in 3 additions until uniform in color
