  • 1 teaspoon ground cinnamon (5ml)
  • 1/4 teaspoon ground nutmeg (1.25ml)
  • 1 tablespoon lemon juice (15 ml)
  • 3 cups rolled oats (not instant) (270g / 9.5 oz)
  • 2 1/2 cups milk (dairy or non-dairy) (600ml / 20 fl oz)
  • 1/2 cup maple syrup (120ml / 4 fl oz)
  • 1/4 cup unsalted butter, melted (60g / 2 oz)
  • 2 large eggs, lightly beaten
  • 1 teaspoon vanilla extract (5ml)
  • 1 teaspoon baking powder (5ml)
  • 1/2 teaspoon salt (2.5ml)
  • 1/2 cup all-purpose flour (60g / 2 oz)
  • 1/4 cup rolled oats (25g / 0.9 oz)
  • 1/4 cup brown sugar, packed (30g / 1 oz)
  • 1/4 teaspoon ground cinnamon (1.25ml)
  • 1/4 cup unsalted butter, cold and cubed (60g / 2 oz)

Instructions:

  1. Prepare the Apple Filling: In a medium bowl, combine diced apples, melted butter, brown sugar, cinnamon, nutmeg, and lemon juice. Toss to coat evenly.
  2. Prepare the Oatmeal Base: In a large bowl, whisk together rolled oats, milk, maple syrup, melted butter, eggs, vanilla extract, baking powder, and salt.
  3. Assemble the Baked Oatmeal: Pour the oatmeal mixture into the prepared baking dish. Spread the apple filling evenly over the oatmeal.
  4. Prepare the Crumble Topping: In a small bowl, combine flour, oats, brown sugar, and cinnamon. Cut in the cold, cubed butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  5. Add the Crumble Topping: Sprinkle the crumble topping evenly over the apple filling and oatmeal.
  6. Bake: Bake in a preheated oven at 375°F (190°C) for 40-45 minutes, or until the top is golden brown and a knife inserted into the center comes out clean.
  7. Cool and Serve: Let cool slightly before serving.
