Sieve the dry ingredients into a bowl with the pepper and make a well in the centre.
Break in the eggs and start stirring, slowly adding the oil and yoghurt as you go along until just combined.
Chop ⅔ of the goat’s cheese into small cubes. Gently mix them in to the flour along with the grated beetroot, walnuts and thyme.
Spoon into a greased 12 hole muffin tin (I used two 6 hole silicone moulds).
Divide the remaining ⅓ cheese into 12 pieces and place one on top of each muffin.
Bake in a preheated oven at 180℃ (350℉, Gas 4) for about 30 minutes or until the muffins are well risen and nicely browned. Leave to cool for a couple of minutes then turn out on to a wire rack to cool completely – or eat whilst warm.
