Add Base batter ingredients to blender, and blend for 30 seconds until it turns into a smooth, runny batter.
Grease an 8-ounce ramekin (or other similar-sized oven-safe dish) with cooking spray, then pour batter mixture into it.
Add the diced apples and chopped pecans into the batter and mix. Top it off with a pinch of extra ground cinnamon.
Pour in the remaining batter, jam mixture, and peanut butter. Give it a stir. This will create layers of PB&J in our baked oats.
Bake it in the air fryer (300°F for 12-15 min) or oven (350°F for 25-30 min).
Take it out, let it cool down for a few minutes, and drizzle a touch of maple syrup on top if you'd like. Enjoy!
