Preheat oven to 375 degrees F.

Spray two 12-cup cupcake tins with cooking spray. Set aside.

Cupcakes

In a medium sized mixing bowl, whisk together the flour, salt and baking powder.

In a large mixing bowl, cream the butter and sugar together.

Next stir the eggs and the vanilla into the sugar cream.

Using an electric mixer, mix the flour into the sugar cream.

Mix for 2 minutes.

Gradually fold the milk into the batter, 1/4 cup at a time until all of the milk has been incorporated.

Pour the batter into the cupcake tins and bake for 12-15 minutes until golden.

Remove cupcakes from the tins and cool on a cooling rack before frosting.

Frosting

In a large mixing bowl cream together the mascarpone cheese, softened butter, vanilla paste and 1/2 cup powdered sugar until smooth.

With an electric mixer gradually mix in the rest of the powdered sugar, 1/2 cup at a time until the full 2 cups is blended in with the cheese and the frosting is fluffy.

Frost the cupcakes and serve.
