Pre-heat the oven to gas 4 / 180C / 350°F and lightly grease a 1 litre baking dish
Gently toss the thinly sliced apples in the greased baking dish with the lemon juice, brown sugar and water
Mix the melted butter and caster sugar together
Mix in the flour, baking powder, baking soda, vanilla, syrup and milk to make a batter. Gluten-free flour will need another couple of tablespoons of milk
Spread the batter over the top of the apples and bake for 40 - 45 minutes until the apples are soft and the sponge is firm and nicely browned
Sprinkle some sugar over the top and serve with hot custard

If you're using any other type of apples it's best to soften the apple filling mixture in a pan on the stove first before baking with the topping on as other apples may not cook through as quickly as Bramleys will
