01 - Combine milk, eggs, fresh spinach leaves, and melted butter in a blender. Process until completely smooth and vibrantly green, ensuring no spinach pieces remain.
02 - Whisk together flour, sugar, baking powder, and salt in a large mixing bowl until evenly distributed.
03 - Pour the blended green mixture into the dry ingredients. Fold gently with a whisk until just combined—stop mixing as soon as the flour disappears. Small lumps are acceptable; overmixing will result in tough pancakes.
04 - Heat a nonstick skillet or griddle over medium heat. Lightly coat the surface with butter, adjusting the heat as needed to maintain even cooking temperature.
05 - Drop approximately 1/4 cup batter per pancake onto the skillet. Cook for 2-3 minutes until bubbles form across the surface and edges appear set and firm.
06 - Carefully flip each pancake and cook for 1-2 minutes until golden brown and cooked through. Transfer to a warm plate and repeat with remaining batter.
07 - Serve pancakes immediately while hot, topped with additional butter and maple syrup as desired.
