In a bowl, whisk together the eggs, mashed banana, vanilla extract, oil, maple syrup and milk until well combined.
In a separate bowl, whisk together the oat flour, almond flour, baking soda and salt.
Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Be careful not to overmix.
Spread the batter evenly into the prepared baking pan or container.
Add dark chocolate squares on top.
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. The edges should be golden brown.
Let cool and enjoy!
