Preheat the oven to 200C/400F/Gas 6.
For the sponge, mix all the sponge ingredients together in a food processor to produce a thick smooth batter.
For the caramelised pear, melt the butter with the sugar in an ovenproof pan over a medium heat until golden-brown.
Add the pear and mixed spice to the caramel and mix together.
Pour the batter over the caramelized pear and place in the oven. Bake for 10 minutes, or until the sponge is risen and cooked through.
To serve, turn the pudding out onto a serving plate, dust with icing sugar and drizzle cream all over.
