Shortly after this photo was taken, Bert’s dad was ‘naughty daddy’ for picking up a piece of cake Bert had dropped. Then I was ‘naughty mummy’ for putting a nappy on him and giving him his blanket before his nap. He’d only go to bed if he was put in an entirely green outfit, and was read three green books. Last night he screamed at me for not having the Peppa Pig towel to hand after his bath.

There is no Peppa Pig towel.

We’re completely terrified of him.

This is a tasty, moist cake. If you find the green speckles disturbing, you could peel the courgettes first.

For the cake:

2 eggs

170g soft butter

140g caster sugar

2 medium courgettes, grated (about 200g)

1 teaspoon vanilla extract

75g self raising flour

75g plain wholemeal flour

1 dessert spoon lime juice

1 teaspoon baking powder

For the topping and filling:

3-4 dessert spoons lime or lemon curd

4 dessert spoons Greek yoghurt

1 cup icing sugar, sifted

1 teaspoon lime juice

Beat together the eggs, sugar, courgette and butter till smooth and light, then fold in the rest of the cake ingredients. Divide between two buttered small loaf tins (mine are 15 x 9cm) and bake at 180 degrees (or the grid shelf on the bottom of the Aga roasting oven with the cool shelf two rows above) for 20-25 minutes, till golden brown and firm.

Leave to cool slightly then turn out onto a rack.

Beat the icing sugar and remaining lime juice into the Greek yoghurt and cool for at least an hour. Spread one completely cooled loaf with curd, sandwich with the other, and then spread the frosting over the top – it should dribble down the sides.
