The Recipe
¾ cup / 185ml cake flour
1 teaspoon baking powder
2 cups / 500ml milk
2 eggs
¾ cup / 185 ml sugar
1 tsp vanilla essence
1 oz / 25g melted butter
pinch salt
½ tsp cinnamon
Preheat the oven to 175C / 350F
Put all the ingredients together into a bowl or food processor and beat to a smooth batter. Pour into a buttered pie dish (approximately 23cm/9" in diameter, but it doesn't matter if it's not exact, the finished tart will just be either a bit deeper or shallower). Sprinkle the cinnamon over the top. Bake for 45 minutes at 175C / 350F. Serve warm or cold.
It sinks and becomes denser as it cools. If you eat it hot you'll need a spoon to scoop up the soft custardy tart, but cold you can pick up the slices in your hand.
