Preheat the oven to 350 degrees Fahrenheit and line a 4x8-inch loaf pan with parchment paper and set aside.
Add the eggs, baking soda, almond butter, and cocoa powder to a blender or food processor and blend until smooth and completely mix, scrape down the sides as needed. Batter will be thick.
Transfer the batter to the prepared loaf pan and spread out evenly.
Top with chocolate chips if desired, or ½ cup of chocolate chips can be folded into the batter. Can also top with flaky salt before baking if desired.
Bake for 27 to 30 minutes or until a toothpick comes clean when inserted into the center.
