It's one of the simplest cakes I've ever made. You don't even need a mixer. Just mix all the ingredients in a bowl and that's it.

1. Preheat your oven to 170 degrees Celsius.

2. In a mixing bowl, cream together the soft butter and sugar until well incorporated.

3. Add the vanilla essence and gradually incorporate the eggs, one at a time, mixing well after each addition.

4. Once the eggs are fully incorporated, sift in the baking powder and cake flour. Mix until there are no lumps, using a spatula or whisk.

5. Line a baking tray with wet baking paper to help it sit better in the tray.

6. Pour the cake batter into the prepared baking tray, leveling it nicely with a spatula.

7. Place the tray in the preheated oven and bake for about 40 minutes, or until a toothpick inserted into the middle of the cake comes out clean.

8. Once baked, remove the cake from the oven and let it cool in the tray for 30 minutes.

9. Once cooled, spread a layer of raspberry jam over the top of the cake.

10. Serve and enjoy!
