Ingredients

Scale

Dry Ingredients

  • 3 cups old-fashioned rolled oats
  • 1½ tsp baking powder
  • 2 tsp ground cinnamon
  • ¼ tsp ground nutmeg
  • ¾ tsp salt
  • ½ cup lightly packed brown sugar

Wet Ingredients

  • 2½ cups milk
  • 2 large eggs
  • 1 tsp vanilla extract
  • 4 tbsp melted butter or coconut oil

Fruit

  • 23 large apples (Honeycrisp or Gala), peeled and diced

Instructions

  1. Prep: Grease a 9×13-inch baking dish to prevent sticking and preheat the oven to 325°F (163°C) ensuring it reaches the proper temperature for even baking.
  2. Mix Dry Ingredients: In a large bowl, whisk together the rolled oats, baking powder, ground cinnamon, ground nutmeg, salt, and brown sugar until well combined, distributing the spices and leavening agent evenly.
  3. Combine Wet Ingredients: In a separate bowl, whisk the milk, eggs, and vanilla extract together until fully blended to ensure a smooth mixture that will bind the oats.
  4. Assemble: Pour the wet ingredients into the dry oat mixture and stir in the melted butter or coconut oil until everything is incorporated uniformly.
  5. Layer: Scatter the peeled and diced apples evenly in the greased baking dish, then pour the oatmeal mixture evenly over the apples, spreading it out gently.
  6. Bake: Place the dish in the preheated oven and bake for 35-45 minutes until the oatmeal is golden on top and fully set in the center. Let it cool slightly before serving to allow it to firm up.

Notes

  • You can substitute apples with pears or berries for a different flavor profile.
  • Use coconut oil for a dairy-free option.
  • Adjust sweetness by varying the amount of brown sugar or using maple syrup instead.
  • Serve warm with a splash of milk or a dollop of yogurt for extra creaminess.
  • Store leftovers covered in the refrigerator for up to 4 days and reheat before serving.
