Preheat oven to 350F. Spray a 10-cup bundt cake with baking spray and set aside.
In a large bowl combine flour, baking powder and salt then set aside.
With a hand mixer or using your stand mixer, cream butter until light and fluffy.
Gradually add sugar and beat on low until combined.
Mix in eggs one at a time. Mix in vanilla extract.
Add flour mixture and milk alternately starting and ending with the flour (third flour mixture, half milk, third flour, the remaining of the milk then ending with the remaining flour). Make sure you scrape the bottom and sides of the bowl halfway through.
Spoon the batter on the prepared pan leveling the top with a spatula.
Bake in the center of your oven for 45-60 minutes.
Prepare the filling and the whipped cream while the cake is baking, directions below.
Let it cool down for 10-15 minutes in the pan until it is cool enough to touch.
Carefully invert the cake on a wire rack and let it cool completely.
