Grease and line an 8 inch round spring form cake tin
Grease the lining paper with a little butter and a drizzle of honey and sprinkle the flaked almonds evenly across the base of the tin
Arrange the pears in a circular fashion with the narrow tops facing into the centre of the tin and the wider ends toward the edge. The middle of the pears should be facing up.
Mix all the ingredients by hand vigorously in a large mixing bowl, with an electric handheld whisk or in a cake mixer until light and fluffy with no lumps of butter
Carefully pour the batter evenly across the pears and try to keep them in place
Smooth over the top with a spatula of spoon and bake at 180C for 40 mins
Allow to cool completely then run a knife around the edge and remove the spring form
Carefully turn the cake upside down onto a serving plate and peel of the base of the tin and the parchment and slice into 8 pieces and serve with a dollop of natural yoghurt
