Preheat oven to 350℉. Line an 8x8 inch brownie pan with parchment paper.
In a large bowl, whisk together the eggs, peanut butter, brown sugar, butter and vanilla until combined. Next, add in the almond flour, oats, baking soda, salt and mix until incorporated. Fold in the chocolate chips. Transfer the thick mixture to the brownie pan and spread out evenly. Optional: top with more chocolate chips. Bake for 20-22 minutes or until golden brown on edges. Allow to set in pan for 15 minutes then carefully transfer to a wire rack to allow to cool.
Optional: Top with flakey sea salt when it comes out of the oven!
