Apple Crumble Slice

Preheat the oven to 180°C. Brush a 20 x 30 cm shallow slice tin with melted butter to grease.
To make the Base, put the flour, baking powder, sugar and butter in the bowl of a food processor and process until the mixture resembles breadcrumbs. Whisk the egg with the vanilla, add to the flour mixture and use the pulse button to process until the mixture forms a soft dough. Bring together with your hands and then press the dough evenly over the base of the greased tin to evenly cover. Place in the fridge.
Meanwhile, to make the Crumble Topping, put the flour and brown sugar in a medium bowl and use your fingertips to rub in the butter until roughly combined. Stir in the coconut and almonds.
Peel, core and thinly slice the apples and put in a large bowl. Combine the sugar and cinnamon, sprinkle over the apples and toss to coat evenly. Arrange the apple slices over the Base in the tin and then sprinkle evenly with the Crumble Topping. Set aside.
Bake in preheated oven for 30-35 minutes or until the base is cooked, the Crumble Topping is golden, the apples are tender when tested with a skewer, and the base is cooked through.
Serve warm or at room temperature cut into portions and accompanied by cream or ice cream.
