Preheat the oven to 200C/400F/Gas 6.
Mix together the cake ingredients in a food processor and spoon even portions into a six-hole, non-stick muffin tin.
Place in the oven and bake for 10 minutes.
For the chocolate sauce, melt the chocolate and chilli flakes in a heat-proof bowl set over boiling water.
To serve, turn out the cakes onto plates and dust with icing sugar. Pour the chocolate sauce over each muffin and drizzle with cream.
