Slice the avocado in half, remove the pit, and add the avocado meat (removing any black spots) to a blender. Add the egg, milk, and melted butter. Close the lid and blend for 15 to 20 seconds until smooth.
In a large bowl, combine the flour, baking powder, and salt. Pour the blended avocado mixture into the bowl, and stir just enough to combine the dry ingredients with the liquid until there's no visible flour left. Let the batter sit for 5 minutes.
Cook the pancakes:
Heat a non-stick griddle or large pan over medium heat. Once hot, grease, spray, or melt butter on the hot surface. When using an electric griddle, heat it somewhere between 300 and 350F. Immediately, pour ¼ cup of pancake batter onto the greased surface.
Cook the pancakes for about 2 minutes, until the edges are defined and bubbles form. Flip the pancakes over and cook for an additional 2 minutes. Avoid pressing down on the pancake after flipping; this will cause denser and chewier pancakes and undercooked batter as it oozes out on the sides. Remove the pancakes from the pan onto a plate and keep them warm, covered with a kitchen towel or on a sheet pan in a 200F oven while you cook the rest.
Serve & Store:
Serving recommendations: for savory avocado pancakes, top them with a fried egg and bacon crumbles. For a sweet stack, sliced fruit (like berries or bananas) and a drizzle of syrup.
Refrigerate leftover cooked pancakes for up to 4 days. To freeze, lay them flat on a parchment-lined baking sheet, then transfer to a zip bag for up to 3 months. Reheat in the microwave (30–60 seconds), toaster, or a pan over low heat.
Notes
Ripe avocados work best for this recipe because they're easier to mash and are sweeter.
Sweet vs savory: these pancakes are quite neutral, making them perfect for savory toppings or next to a fried egg and bacon. To make them sweeter or top them with fruit, you can add 2 tablespoons of honey or sugar to the blender or ½ ripe banana (about ⅓ cup).
