Ingredients

Scale
  • 6 medium apples (about 2 lbs) – mix Granny Smith and Braeburn, peeled, cored, and sliced
  • 2 tablespoons granulated sugar
  • 1 tablespoon brown sugar
  • 1 teaspoon ground cinnamon
  • 1 teaspoon fresh lemon juice
  • 1 tablespoon unsalted butter
  • 1 cup all-purpose flour (125g)
  • 1/2 cup rolled oats (45g)
  • 1/2 cup brown sugar (100g)
  • 1/2 teaspoon ground nutmeg (optional)
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter (115g), cold and cubed
  • 2 cups whole milk (480ml)
  • 4 large egg yolks
  • 1/3 cup granulated sugar (65g)
  • 2 tablespoons cornstarch
  • 1 teaspoon pure vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9-inch baking dish with butter.
  2. Peel, core, and slice apples into 1/4-inch thick slices. Toss with granulated sugar, brown sugar, cinnamon, and lemon juice.
  3. Melt butter in a skillet over medium heat. Add apple mixture and cook for about 5 minutes until apples soften but hold shape. Set aside to cool.
  4. In a medium bowl, combine flour, rolled oats, brown sugar, nutmeg (if using), and salt.
  5. Add cold cubed butter to dry ingredients. Use a pastry cutter or fingers to rub butter into mixture until coarse crumbs form with some pea-sized bits.
  6. Transfer cooked apples to the greased baking dish and spread evenly. Sprinkle crumble topping evenly over apples.
  7. Bake for 40-45 minutes until topping is golden brown and apples are bubbling. Cover with foil halfway if topping browns too quickly.
  8. While baking, warm milk in a saucepan over medium heat until steaming but not boiling.
  9. In a separate bowl, whisk egg yolks, sugar, and cornstarch until smooth.
  10. Temper eggs by slowly adding about 1/2 cup warm milk to egg mixture, whisking constantly.
  11. Pour egg mixture back into saucepan with remaining milk. Cook over medium-low heat, stirring constantly until custard thickens, about 5-7 minutes.
  12. Remove from heat and stir in vanilla extract. Let custard cool slightly.
  13. Serve warm apple crumble with a generous drizzle of creamy custard.

Notes

Use cold butter for the crumble topping to achieve a flaky, crisp texture. Temper eggs slowly with warm milk to prevent curdling. If topping browns too quickly, cover with foil halfway through baking. Lemon juice keeps apples bright and prevents browning. For gluten-free, substitute almond or gluten-free oat flour. For vegan, use plant-based milk and butter substitutes.
