Ingredients
  

Ingredients
  • 2 cups old-fashioned oats
  • 1 ½ cups milk (or almond milk for dairy-free)
  • 1 large apple, diced
  • 2 eggs
  • ¼ cup maple syrup or honey
  • 1 tsp vanilla extract
  • 1 tsp cinnamon
  • ½ tsp baking powder
  • ¼ tsp salt
  • ¼ cup chopped walnuts or pecans (optional)

Equipment

  • 8x8-inch baking dish
  • Large mixing bowl
  • Whisk
  • Spatula or wooden spoon
  • Wire rack

Method
 

Instructions
  1. Preheat & Prep: First things first, get your oven preheating to 350°F (175°C). While it’s coming to temperature, grab an 8x8 inch baking dish (or a similar size) and give it a light greasing with butter or non-stick spray. This simple step is key to making sure your delicious bake comes out cleanly later.
  2. Mix the Wet Ingredients: In a large mixing bowl, crack in the two eggs and give them a light whisk just to break up the yolks. Pour in the milk, maple syrup, and vanilla extract. Whisk everything together until it’s uniformly combined. This forms the creamy custard base for your bake.
  3. Add the Dry Ingredients: Now, add the old-fashioned oats, baking powder, cinnamon, and salt directly into the wet ingredients. Stir with a spatula or wooden spoon until everything is just moistened. Be careful not to overmix here; you just want to ensure there are no dry pockets.
  4. Fold in the Good Stuff: Gently fold in your diced apples and the chopped nuts, if you're using them. I love the crunch and flavor walnuts bring, but it’s just as good without. Make sure the apples are evenly distributed throughout the batter.
  5. Pour and Bake: Pour the entire mixture into your prepared baking dish. Use your spatula to spread it into an even layer, making sure it reaches all the corners. Pop it into the preheated oven.
  6. Bake to Golden Perfection: Let it bake for 30-35 minutes. You'll know it's done when the top is a beautiful golden brown, the edges are slightly pulling away from the dish, and the center feels firm to the touch. A toothpick inserted into the center should come out clean.
  7. Cool and Serve: Carefully remove the dish from the oven and let it cool on a wire rack for at least 5 minutes. This helps it set up properly, making it easier to cut and serve. Enjoy it warm, perhaps with a splash of milk or an extra drizzle of maple syrup.

Notes

For best results, use Granny Smith or Honeycrisp apples for a tarter, firmer bite, or Gala/Fuji for a sweeter, softer apple. This recipe requires old-fashioned (rolled) oats; do not use instant or steel-cut oats. For variations, you can make it dairy-free with almond milk, vegan with flax eggs, and gluten-free by using certified gluten-free oats. The nuts are optional for a nut-free version. The bake can be stored in the refrigerator for up to 5 days or frozen for up to 3 months.
