Ingredients:

  • 6 cups (approx. 1kg) peeled and sliced apples (mixed Granny Smith and Honeycrisp)
  • 1/2 cup (100g) granulated sugar
  • 1 tbsp (8g) ground cinnamon
  • 2 tbsp (16g) all-purpose flour
  • 1 tbsp (15ml) lemon juice
  • 1 cup (90g) old fashioned rolled oats
  • 1 cup (125g) all-purpose flour
  • 1 cup (200g) packed light brown sugar
  • 1/2 tsp (3g) ground cinnamon
  • 1/2 tsp (3g) salt
  • 1/2 cup (113g) cold unsalted butter, cubed

Instructions:

  1. Preheat your oven to 375°F (190°C).
  2. Toss the sliced apples with lemon juice, granulated sugar, cinnamon, and flour in a large bowl until every slice is coated. Spread the mixture evenly into a 9x9 inch baking dish.
  3. In a separate bowl, whisk together the oats, flour, brown sugar, cinnamon, and salt.
  4. Add the cold, cubed butter to the dry mixture. Use a pastry cutter or fingers to work the butter in until the mixture resembles coarse crumbs with some pea-sized lumps remaining.
  5. Scatter the topping evenly over the apples without pressing it down to ensure maximum airflow.
  6. Bake for 40–45 minutes until the topping is deep mahogany brown and the apple juices bubble thick and slow around the edges.
