Preheat the oven to 350 F. Line 2, 9 inch cake pans with parchment paper and put some butter on the sides.
In a large dish combine flour, baking powder and salt. Set aside.

In a separate dish beat butter and sugar, at high speed, until light and fluffy, for about 3 minutes. Add eggs, one at a time and vanilla,beat until creamy.

Spread into 2 cake pans. Bake for 35-40 minutes, or until a toothpick comes out clean or with a few crumbs on it.
Take out of the oven and leave for a few minutes to cool in cake pans, then transfer to a wire rack to cool completely.

Add ½ flour mixture and beat at a low speed until combined. Add milk and continue beating until combined.
Finally, add the rest of the flour mixture and beat for about 2-3 minutes at medium speed.

Add powdered sugar and vanilla and mix until smooth.
Remove the parchment paper.
Place one layer of vanilla cake on the bottom of a cake stand or a plate.

Spread 1/3 of frosting over it. Put another vanilla cake layer and press lightly.
Spread the rest of the frosting on the top and on the sides of the cake.

In a cool large dish, beat heavy whipping cream with electric mixer until stiff peaks form. Set aside.
