Method
Preheat the oven to 170 degrees
Grease two 20cm sandwich tins and line the base with greaseproof paper or baking parchment then dust the sides with a little flour
Beat together (by hand or with an electric mixer) the Castle Dairies butter, the caster sugar and vanilla extract into a creamy, light consistency
Slowly add and beat in the eggs one at a time until smooth then fold the self raising flour in and mix until smooth
Divide the mixture out evenly between the tins and bake for 20-30 minutes until they’re risen and are golden brown
Cool for 10 minutes and then remove the bases and cool on a rack
When the cakes are cold spread the jam and whipped double cream onto one cake then place the other cake layer on top and dust with icing sugar to finish! Enjoy!
