Step 1
Preheat the oven to 170 C/Gas 3-4. Grease and line two 18cm (7 in) tins with baking parchment.
Step 2
Sieve the flour into a bowl and add the sugar, butter and vanilla extract. Crack the eggs and mix well, until light and fluffy.
Step 3
Divide the mixture evenly between the tins. Use a spatula to remove any excess from the bowl and gently smooth the surface of the mixture in the tins.
Step 4
Place the tins on the middle shelf of the oven and bake for 25 minutes or until golden brown. Leave the cakes to cool in the tin for 5 minutes and then turn out onto a wire rack to cool.
Step 5
Once cakes have cooled, place one of the cakes upside down on a plate and spread with jam and cream. Place the other cake on top and sprinkle with caster sugar.
