Preheat the oven to gas 3/160 c/150.
Prepare a regular sized bundt tin – 2.4l, 10 cup, 10 inch with melted butter and dust with flour.
Cream the butter and sugar until pale and fluffy. Add the eggs one at a time, beating well after each addition.
In a separate bowl, measure out the flour, bicarbonate of soda, salt and spices.
Pour the yoghurt into a jug, and add the apple sauce and vanilla extract.
Add a third of the flour mix into creamed butter/sugar, followed by half the yoghurt. Repeat this until everything is combined. Stir in the grated apple.
Give everything a quick mix on a low speed for about 10 seconds.
Pour the mix into your prepared tin. Bake in the centre of the oven for about 1 hour 15 minutes or until a skewer comes out clean.
Leave the cake to cool for ten minutes before removing from the tin. When completely cool, stir the caramel and tip it over the cake.
