In a small pot over medium-high heat, add the oats, water and almond milk. Bring to a gentle boil then reduce heat to low and simmer for 10 to 12 minutes or until the oats are tender. Stir occasionally to prevent burning.
Add in the cocoa powder and maple syrup. Whisk until combined.
Slowly add in the egg whites. Whisk continuously for 2 minutes until oatmeal is thick and creamy.
Remove the pot from the heat, transfer oats to a bowl and top with berries. Enjoy!
