Preheat the oven to 190°C.

Grease two 20cm cake pans with butter and then place non-stick baking paper on the bottom.

Combine caster sugar, butter, eggs, self-raising flour, baking powder, and milk in a large bowl. Mix until a smooth and soft batter is formed.

Distribute the mixture evenly between the tins and use a spatula or the back of a spoon to level the surface.

Cook in the oven for approximately 20 minutes or until the cake turns a golden color and springs back when touched.

Transfer to a cooling rack and allow it to cool fully.

In order to create the filling, start by thoroughly mixing the butter until it becomes smooth and creamy. Next, gradually add the sifted icing sugar and vanilla extract while continuing to beat the mixture.

Take the filling and spread it evenly on one of the sponges. Add a layer of strawberry jam on top of the filling and then place the second sponge on top. Lastly, sprinkle icing sugar over it.
