First weigh the eggs in their shells, then weigh equal amounts of butter, sugar and flour.
4 eggs
Cream the butter and sugar until light and fluffy.
275 g unsalted butter, 275 g golden caster sugar
Beat in the eggs one by one. If the mixture starts to curdle, add a spoonful of flour.
Sieve the flour and baking powder and throw any bran remaining in the sieve into the compost bin.
275 g wholemeal flour (whole wheat), 2 tsp baking powder
Gently stir the flour into the sponge mixture, followed by the kefir until everything is just combined.
2 tbsp kefir, buttermilk, sour milk or watered down yoghurt
Divide the mixture between two 22cm round silicone moulds or lined baking tins and bake at 180℃ (350℉, Gas 4) for 30 minutes or until an inserted skewer comes out clean.
Leave in the moulds to cool for about 10 minutes, then turn out onto a wire rack to cool completely.
Sandwich the cakes with strawberry jam, then dust with icing sugar or caster sugar and serve.
8 tbsp strawberry jam, icing sugar
