1. Preheat the oven to 180C/350F/Gas 4.

2. Grease and line 2 x 18cm/7in cake tins with baking paper.
 
3. Cream the butter and the sugar together in a bowl until pale and fluffy.
 
4. Beat in the eggs, a little at a time, and stir in the vanilla extract.

5. Fold in the flour using a large metal spoon, adding a little extra milk if necessary, to create a batter with a soft dropping consistency.
 
6. Divide the mixture between the cake tins and gently spread out with a spatula.

7. Bake for 20-25 minutes, or until golden-brown on top and a skewer inserted into the middle comes out clean.

8. Remove from the oven and set aside for 5 minutes, then remove from the tin and peel off the paper. Place onto a wire rack.

9. Sandwich the cakes together with jam, lemon curd or whipped cream and berries or just enjoy on its own.
