Follow these steps carefully to create an amazing Chantilly Cake:

1. Preheat your oven to 350°F (175°C).
2. Grease and flour two 9-inch round cake pans.
3. In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
4. Add eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.
5. In a separate bowl, combine the flour, baking powder, and salt.
6. Gradually add the dry ingredients to the wet mixture, alternating with the milk. Start and end with the dry ingredients, mixing until just combined.
7. Divide the batter evenly between the two prepared cake pans.
8. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean.
9. Once baked, remove the cakes from the oven and allow them to cool in the pans for about 10 minutes.
10. Transfer the cakes to wire racks to cool completely.
11. In a large mixing bowl, whip the heavy cream until soft peaks form. Slowly add powdered sugar and continue whipping until stiff peaks form.
12. Once the cakes are cool, place one layer on a serving platter and spread a generous amount of whipped cream on top.
13. Place the second layer on top of the whipped cream and cover the entire cake with the remaining whipped cream.
14. Garnish with fresh fruit on top or around the edges as desired.
