Preheat the oven to 350°F. Grease and flour two 9-inch cake pans.
In a medium bowl, whisk together the flour, baking powder, and salt.
In a large bowl, cream the butter and sugar together until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Gradually add the flour mixture to the butter mixture, alternating with the milk, until the batter is smooth.
Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
Let the cakes cool completely on a wire rack.
To make the Chantilly cream, beat the heavy cream, powdered sugar, and vanilla extract together until stiff peaks form.
Place one cake layer on a serving plate. Spread a layer of Chantilly cream on top. Add the second cake layer and spread another layer of Chantilly cream on top.
Decorate the top of the cake with fresh berries.
Chill the cake in the refrigerator for at least 30 minutes before serving.
Enjoy your delicious and creative Chantilly Cake!
