Preheat the Oven

In a large bowl, whisk together the flour, sugar, baking powder, and salt until well combined.

Combine Dry Ingredients

In another bowl, cream the unsalted butter until smooth. Gradually add the sugar and continue to beat until light and fluffy.

Add the eggs one at a time to the butter mixture, beating well after each addition. Stir in the vanilla extract.

Gradually add the dry mixture to the wet mixture, alternating with milk, beginning and ending with the flour mixture. Mix until just combined.

Pour the cake batter into a greased 9x13 inch baking pan. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.

Once baked, remove from the oven and let the cake cool in the pan for 10 minutes before transferring to a wire rack to cool completely.

For the creamy layer, whisk together 1 cup of heavy cream, 1/4 cup of powdered sugar, and 1 tsp of vanilla extract until soft peaks form.

Spread the creamy top layer evenly over the cooled cake. You can decorate it with chocolate shavings or fruit if desired.
