Using a pan that is suitable for both hob and oven, approx 22cm across; heat the
topping ingredients gently until the sugar has dissolved and the juices begin to
run. Set aside
Preheat the oven to 200/180 fan.
Sieve the flour, bicarbonate of soda, and baking powder together.
Mix the remaining ingredients together, then pour into the dry ingredients and stir
quickly. Pour over the plum mixture, - it will look very juicy and you will think
‘this has gone wrong!’ - but keep going, and try to cover the plums with the batter.
Then put the pan into the oven and cook for 30 minutes.
Let the cake cool in the pan, (but not too much or it will stick) then place a plate
over the top and invert.
