Weigh out the flours and tip into a large mixing bowl. Add the salt, baking powder and bicarb.
250 g wholemeal spelt flour, 50 g buckwheat flour, 2 tsp baking powder, ¼ tsp bicarbonate of soda (baking soda), 1 pinch fine sea or rock salt
Cut the butter into small cubes, then add to the bowl. Rub the butter lumps into the flour with your fingertips until the mixture resembles breadcrumbs.
150 g unsalted butter
Add the sugar and stir.
150 g golden caster sugar
Peel, core and dice the apples finely. Add them to the bowl then stir into the mixture to coat so the apples don't brown.
300 g cooking apples
Make a well in the centre of the mix and break in the eggs. Add the kefir and stir from the inside out until everything is well combined.

Scrape the mix into a 23 cm (9 inch) round silicone cake mould or lined tin.
Topping
Core and finely slice the apple, but leave the peel on.

Drizzle the lemon juice over the top to stop the slices from browning. Then arrange the slices around the top of the cake.
1 tbsp lemon juice
Scatter the sugar over the apple.
1 tbsp demerara sugar
Bake in a preheated oven at 180℃ (160℃ fan, 350℉, Gas 4) for 45 minutes or until an inserted skewer comes out more or less clean.
Notes
You can leave out the chocolate, but I highly recommend it.It will keep well in sealed container for 4-5 days. But it's at its absolute best served warm on the day of baking with clotted cream.You’ll find additional tips and info about this recipe in the main body of the post.Please note: calories and other nutritional information are per serving.
