Ingredients

Scale
  • 2 medium apples (Honeycrisp or Granny Smith), peeled and diced
  • 1 tablespoon unsalted butter
  • 2 tablespoons brown sugar
  • 1 teaspoon ground cinnamon
  • 1 squeeze lemon juice
  • 2 cups rolled oats
  • 1 teaspoon baking powder
  • 1 pinch salt
  • 1 ½ cups milk (any kind)
  • 2 large eggs
  • ¼ cup maple syrup
  • 1 teaspoon vanilla extract
  • ½ cup rolled oats (for topping)
  • ¼ cup all-purpose flour
  • ¼ cup brown sugar
  • ½ teaspoon ground cinnamon
  • 3 tablespoons cold unsalted butter, cubed
  • ¼ cup chopped pecans or walnuts (optional)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease an 8×8-inch baking dish with butter or cooking spray.
  2. Make the apple filling: In a medium skillet over medium heat, melt 1 tablespoon unsalted butter. Add diced apples, 2 tablespoons brown sugar, 1 teaspoon cinnamon, and a squeeze of lemon juice. Cook for 5-7 minutes, stirring occasionally, until apples are softened and mixture is bubbly. Transfer to the prepared baking dish and spread into an even layer.
  3. Mix the oatmeal base: In a large bowl, whisk together 2 cups rolled oats, 1 teaspoon baking powder, and a pinch of salt. In a separate bowl, whisk together 1 ½ cups milk, 2 large eggs, ¼ cup maple syrup, and 1 teaspoon vanilla extract. Pour wet ingredients into dry and stir until just combined (a few lumps are fine).
  4. Pour the oatmeal mixture over the apples in the baking dish. Use a spatula to spread evenly.
  5. Make the crisp topping: In a small bowl, combine ½ cup rolled oats, ¼ cup all-purpose flour, ¼ cup brown sugar, and ½ teaspoon cinnamon. Add 3 tablespoons cold cubed butter. Use a pastry cutter, fork, or fingers to work butter into dry ingredients until mixture resembles coarse crumbs. Stir in ¼ cup chopped nuts if using. Sprinkle topping evenly over the oatmeal.
  6. Bake for 30-35 minutes, until the center is set and top is golden brown. If top browns too quickly, tent loosely with foil for the last 10 minutes.
  7. Let cool for 5-10 minutes before serving. Scoop into bowls and enjoy warm.

Notes

For a creamier texture, let the oatmeal base sit for 5 minutes before pouring over apples. Don’t skip sautéing the apples—it caramelizes them and concentrates flavor. Use cold butter for the topping to ensure a crumbly texture. Let the oatmeal rest after baking to set properly. Leftovers can be stored in an airtight container in the refrigerator for up to 5 days, or frozen for up to 3 months.
