Preheat the oven to 350 degrees Fahrenheit and line a large cookie sheet with parchment paper to prevent sticking.
Whisk the eggs in a mixing bowl until they are well-beaten, then add in the peanut butter and pure maple syrup, stirring until everything is well-combined.
Incorporate rolled oats, baking soda, ground cinnamon (if using), and sea salt into the wet mixture until a thick, sticky dough forms.
Mix in chocolate chips thoroughly so that they are evenly distributed throughout your cookie dough.
Drop mounds of dough onto the prepared baking sheet; you can choose to make giant cookies or smaller ones based on your preference.
Bake for 9 to 12 minutes or until cookies appear set. Let them cool on the baking sheet for about 10 minutes before serving, allowing them to firm up slightly.
