Instructions

Preheat oven to 350°F (175°C) and grease an 8×8-inch baking dish or line with parchment paper.
In a large bowl, combine oats, baking powder, salt, cinnamon, nutmeg, and brown sugar. Stir until well mixed.
In another bowl, whisk together the eggs, milk, melted butter, and vanilla extract until smooth.
Pour the wet mixture into the dry ingredients and stir until fully combined.
Fold in the diced apples and chopped walnuts (if using).
Transfer the mixture into the prepared baking dish and smooth out the top.
Bake for 35–40 minutes, or until the top is golden brown and the center is set. A toothpick should come out clean.
Let cool for 5–10 minutes before serving warm or storing for later.

Notes

Use crisp apples like Honeycrisp or Granny Smith for best texture.
Make it dairy-free by using plant-based milk and oil instead of butter.
Store leftovers in the fridge for up to 5 days or freeze for up to 2 months.
Reheat in the microwave with a splash of milk to refresh texture.
Add-ins like raisins or shredded coconut can offer extra flavor and texture.
