Preheat your oven to 350°F (175°C).
Grease and flour a 9-inch round cake pan.
In a large bowl, cream together the softened butter and sugar.
Add eggs one at a time, beating well after each addition.
Mix in the vanilla extract and crushed pineapple.
In another bowl, whisk together flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture.
Pour the batter into the prepared cake pan.
Bake for 30 minutes or until a toothpick comes out clean.
Allow to cool before removing from the pan.
Whip the heavy cream and spread over the cooled cake, then garnish with pineapple slices and berries.
