Preheat oven to 375°F (190°C).
In a large bowl, mix together the rolled oats, almond milk, maple syrup, vanilla extract, and ground cinnamon.
Transfer the oat mixture to a baking dish and top with sliced almonds and chopped dark chocolate.
Bake for 20-25 minutes, or until the oats are set and the top is golden brown.
Serve warm and enjoy!
