Preheat your oven to 350°F (175°C) and grease an oven-safe baking dish (approx 8×8″)
Mix the almond milk with a tablespoon of flaxseed meal in a bowl, and let it sit for 5 minutes.
Add your baking powder, cinnamon, salt, vanilla extract, apple sauce (or maple syrup), vegan butter and sugar to the bowl and stir to combine.
Then add in your rolled oats and chopped pecans and stir again.
Chop up your apples into bite-sized pieces and add them into the bowl, stirring to make sure everything is well mixed.
Transfer the mixture into your greased baking dish and bake for 35 to 40 minutes. The oats should be turning golden brown around the edges and the oats well set.
Let it cool for around 15 minutes before serving.
