Apple Crumble

Wash, core, and chop the apples into bite-sized pieces. Place them in a large bowl.

Squeeze the juice of half a lemon over the apples and toss to combine to prevent browning.

To the apples, add 1/4 cup brown sugar, 1/4 cup granulated sugar, vanilla extract, and 1 tsp of cinnamon. Mix until the apples are evenly coated.

In a separate bowl, prepare the crumble topping. Combine rolled oats, all-purpose flour, 1 cup brown sugar, 1/2 cup granulated sugar, and 1 tbsp cinnamon. Whisk to combine.

Cut the cold butter into small cubes and add it to the dry topping ingredients.

Using your hands, work the butter into the flour mixture until it resembles coarse crumbs with some pea-sized pieces of butter remaining.

Pour the apple filling into a baking dish and spread it into an even layer.

Sprinkle the crumble topping evenly over the apple filling.

Bake at 375°F (190°C) for 45-50 minutes, or until the topping is golden brown and the filling is bubbly.

Let cool slightly before serving. Serve warm with a scoop of vanilla ice cream, if desired.
