Ingredients:

  • 6 large apples (approx. 2 lbs), mixed Granny Smith and Honeycrisp, cored and sliced 1/4 inch thick
  • 1/4 cup granulated sugar
  • 2 tsp ground cinnamon, divided
  • 1 tbsp fresh lemon juice
  • 1 tsp cornstarch
  • 1 cup old-fashioned rolled oats
  • 1 cup all-purpose flour
  • 1 cup light brown sugar, packed
  • 1/2 tsp baking powder
  • 1/4 tsp fine sea salt
  • 1/2 cup unsalted butter, cold and cubed

Instructions:

  1. Preheat your oven to 375°F (190°C). In a 9x9 inch baking dish, toss the sliced apples with lemon juice, granulated sugar, cornstarch, and 1 teaspoon of cinnamon until evenly coated.
  2. In a separate large mixing bowl, whisk together the flour, brown sugar, oats, remaining 1 teaspoon of cinnamon, baking powder, and salt.
  3. Add the cold, cubed butter to the dry oat mixture. Use a pastry cutter or two forks to cut the butter into the mix until it forms pea-sized crumbs and holds together when squeezed.
  4. Spread the oat crumble evenly over the apple mixture in the baking dish, ensuring the edges are covered to trap steam.
  5. Bake for 45 minutes, or until the fruit is bubbling and the topping has turned a deep golden brown and feels rigid to the touch.
