Whisk together eggs, mashed avocado, melted butter, and milk.
In a separate bowl, whisk together flour, baking soda, salt, and pepper.
Gently combine wet ingredients with flour mixture, just until almost combined. Fold in green onion and cilantro.
Heat a griddle over medium heat. Once it's hot, melt a little butter onto griddle. Use a 1/4 cup measuring cup to pour pancake batter onto hot buttered griddle.
Cook until first side is golden brown and bubbles are hitting the surface of the batter, about 2-3 minutes. Flip and cook until second side is golden and pancakes are cooked through, another 2-3 minutes.
If desired, keep pancakes warm in a 200° F oven while you finish cooking all the pancakes.
Enjoy with your chosen toppings!
