Place the flour, polenta, sugar, butter, eggs and milk into a food processor and blend until the mixture is smooth.
Pour the honey into the base of the microwave-safe bowl and arrange orange slices on top of the honey at the base of the bowl.
Pour over the polenta mixture and cover the bowl with cling film. Microwave at highest setting for five minutes or until cooked through.
