Ingredients Equipment Method Notes

Ingredients
  

  • 2 cups old-fashioned rolled oats
  • 1.5 tsp baking powder
  • 1.5 tsp ground cinnamon
  • 0.25 tsp salt
  • 2 cups milk of choice (almond, oat, or dairy)
  • 0.33 cup pure maple syrup or honey
  • 1 large egg (or flax egg)
  • 2 tsp vanilla extract
  • 2 tbsp melted coconut oil or butter
  • 2 medium apples, peeled and diced (about 2 cups)
  • Optional toppings: apple slices, nut butter, chopped nuts

Equipment

  • mixing bowl
  • whisk
  • 8x8 baking dish
  • spatula
  • oven

Method
 

  1. Preheat oven to 375°F (190°C) and grease an 8x8-inch baking dish.
  2. Whisk rolled oats, baking powder, cinnamon, and salt in a large mixing bowl.
  3. Add milk, maple syrup, egg, vanilla, and melted coconut oil to the bowl. Whisk to combine.
  4. Fold in the diced apples until evenly distributed.
  5. Pour the mixture into the prepared dish, smooth the top, and optionally arrange apple slices on top. Bake 30–35 minutes, until set and golden.
  6. Cool for 10–15 minutes before slicing. Serve warm with yogurt, milk, or extra maple syrup.

Notes

Use rolled oats only—never quick or steel-cut. For vegan, use a flax egg. Use tart apples like Granny Smith for best balance. Add nuts or raisins for extra texture.
