Preheat your oven to 375°F (190°C) and lightly grease two oven-safe ramekins with cooking spray or coconut oil.
In a small bowl, toss the finely diced apples with 1 tablespoon of maple syrup and cinnamon until fully coated.
In a medium mixing bowl, whisk together the almond milk, egg, maple syrup, and vanilla extract. Stir in the rolled oats, baking powder, cinnamon, and salt.
Fold half of the cinnamon apples and the chopped pecans into the oat batter.
Divide the mixture between the two ramekins. Top with the remaining apples. Bake for 25 minutes until the oats are set and the apples are bubbling and caramelized. Drizzle with extra maple syrup before eating.
