Instructions
Preheat oven to 375°F (190°C). Butter an 8–9 inch square or round baking dish.
In a large bowl, toss the sliced apples with lemon juice. Sprinkle over the flour, brown sugar, salt, and cinnamon, and toss again to coat. Place the apples loosely into the prepared baking dish.
Stir together the water and vanilla, then pour over the apples. Drizzle the melted butter evenly across the top.
Make the crumble topping
In a separate bowl, combine flour, oats, brown sugar, baking powder, cinnamon, and salt. Add the cold butter pieces and use your fingers to rub it into the mixture until it resembles coarse crumbs.
Assemble and bake
Scatter the crumble topping evenly over the apples. Bake on the middle rack for 35–40 minutes, or until the topping is golden brown and the apples are bubbling underneath.
Serve
Allow to cool slightly before serving. Enjoy warm, plain or with a scoop of vanilla ice cream or a dollop of whipped cream.
Notes
Tip: For a nutty twist, mix ¼ cup chopped walnuts or pecans into the topping before baking.
