  • 1/4 tsp nutmeg
  • 1/4 tsp salt
  • 2 large eggs
  • 1 3/4 cups milk

  • 2 tbsp melted butter
  • 1 tsp vanilla extract
  • 2 apples, peeled and diced
  • 1/4 cup chopped pecans or walnuts (optional)

Equipment

  • mixing bowls
  • whisk
  • spatula
  • measuring cups and spoons

Method
 

  1. Preheat your oven to 350°F and lightly grease an 8x8-inch baking dish.
  2. In a large bowl, combine oats, baking powder, cinnamon, nutmeg, and salt.
  3. In a separate bowl, whisk together eggs, milk, maple syrup, melted butter, and vanilla extract.
  4. Stir the wet ingredients into the oat mixture until fully combined. Fold in the diced apples.
  5. Pour the mixture into the prepared baking dish and spread evenly.

  7. Bake for 35 to 40 minutes until golden brown and set in the center.

Notes

Use old-fashioned rolled oats for the best texture and avoid overbaking to keep the oatmeal moist. Sweet apples like Honeycrisp or Fuji work best. Add a splash of milk when reheating to restore softness. This recipe is great for meal prep and can be frozen in individual portions.
