Remove seeds from plums and slice into wedges.
In a bowl mix together flour, sugar, egg replacer and salt.
Add in milk and vanilla and mix until sugar dissolves and the batter is lump free.
Grease a small loaf pan with butter.
Pour 1/4th of the batter and bake for 5 minutes until the top is firm.
Now arrange the plum wedges on top and pour the remaining batter. Reserve a few wedges to top after you pour the batter.
Bake the clafouti for 30-40 minutes or until slightly browned at the edges.
