Apple Crumble with Warm Vanilla Custard

Preheat oven to 375°F (190°C).

In a bowl, toss the sliced apples with lemon juice, 2 tablespoons brown sugar, and cinnamon.

Pour the apple mixture into an 8-inch baking dish.

In a separate bowl, combine the flour, oats, and 1/4 cup brown sugar.

Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.

Sprinkle the crumble topping evenly over the apples.

Bake for 30-35 minutes, or until the topping is golden brown and the apples are tender and bubbling.

While the crumble is baking, prepare the custard. In a medium saucepan, whisk together milk, egg yolks, sugar, and salt.

Cook over medium-low heat, stirring constantly, until the custard thickens enough to coat the back of a spoon (about 8-10 minutes). Be careful not to boil.

Remove from heat and stir in the vanilla extract.

Let cool slightly. Serve the warm apple crumble with warm vanilla custard.
