In a small bowl or jar, whisk together almond milk, Greek yogurt, applesauce, protein powder, chia seeds, and cinnamon until well combined.
Cover and refrigerate for at least 2-3 hours, or overnight, until the chia seeds have expanded and the mixture is thick and creamy.
In a small pan over medium heat, add the diced apple, a sprinkle of cinnamon, and a splash of water. Cook for 5–7 minutes, stirring occasionally, until the apples are soft and lightly caramelized.
Spoon the chia pudding into a jar or bowl, top with the warm cinnamon apples, and enjoy immediately – or chill again for a cool, meal-prep version.
