Combine the almond milk, oats, and maple syrup in an airtight container. Mix well and refrigerate 8 hours or overnight.
Divide the oat mixture between 4 bowls (or dish out 1/4 of the mixture and keep the rest in the refrigerator for another day).
Divide the granola, blackberries, blood oranges, and walnuts on top of the oatmeal bowls. I like to put the in a line to make it look pretty but you can just pile them on top.
Finish with a sprinkle of sea salt and enjoy!
