Preheat the oven to 400°F. Grease or line an 8×8 inch baking dish.
In a large mixing bowl, add the beaten eggs, almond milk, maple syrup and vanilla. Mix until wet ingredients are well combined.
To the mixing bowl, add old fashioned rolled oats, baking powder, cocoa powder, salt and chocolate chips. Mix until dry ingredients are completely mixed into the wet ingredients.
Allow the batter to sit for 10 minutes (this allows the oats to absorb some of the liquid). Next, pour the batter into the greased baking dish.
Bake the chocolate oatmeal at 400°F for 30-35 minutes, or until the center of the baked oatmeal is set.
Allow the baked oatmeal to cool for 10 minutes before cutting into four pieces and removing from the pan. Top with desired toppings and enjoy!
