Preheat the oven to 350°F (175°C). Grease and flour a cake pan.

In a mixing bowl, cream together the softened butter and sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In another bowl, whisk together the flour, baking powder, and salt. Gradually add to the wet mixture, mixing until just combined.

Pour the batter into the prepared cake pan and smooth the top.

Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Let the cake cool in the pan for 10 minutes before transferring to a wire rack to cool completely.

While the cake is cooling, prepare the fruit topping by mixing the berries, banana, kiwi, and peach in a bowl.

In a separate bowl, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form.

Once the cake is completely cool, spread the whipped cream over the top.

Top with the mixed fruit and serve immediately.
