Preheat the oven to 180℃/160℃ fan/350℉/gas mark 4.
Peel, core and thinly slice the apples. Place them in a large bowl, squeeze over the lemon juice and toss to coat.
1.5 kg apples (8-10 apples)*, the juice of 1 lemon
Add the maple syrup, cornflour, cinnamon, nutmeg, allspice, vanilla and a pinch of salt. Stir really well so that the apples are evenly coated.
85 g (¼ cup) maple syrup, 15 g (2 Tablespoons) cornflour (cornstarch), 1 teaspoon ground cinnamon, ¼ teaspoon ground nutmeg, ¼ teaspoon ground allspice, 1 teaspoon vanilla extract
Tip the apple mixture into a 20-23 x 30-33 cm/9 x 13 in baking dish and spread level. Dot over the butter in small pieces.
30 g (2 Tablespoons) vegan butter
To make the cobbler topping, mix together the milk and vinegar in a small jug, set aside.
160 g (⅔ cup) unsweetened non-dairy milk (I use soy), 2 teaspoons vinegar
Mix together the flour, baking powder and cinnamon in a bowl. Add the cold, cubed butter and rub it in using your fingertips until no lumps of butter remain.
280 g (2 + ⅓ cups) plain (all-purpose) flour, 1 Tablespoon baking powder, 1 teaspoon ground cinnamon, 120 g (½ cup) vegan block butter
Stir in the sugar then add the milk mixture and stir to make a thick batter.
75 g (6 Tablespoons) light brown soft sugar
Dollop spoonfuls of the batter over the apples, it does not need to completely cover them.
Bake the cobbler for 45-55 minutes until the topping is golden brown and the filling is bubbling. Allow to cool for 15-20 minutes before serving.
