01 - Combine milk, eggs, fresh spinach leaves, and melted butter in a blender. Blend until completely smooth and vibrant green, ensuring no spinach pieces remain.
02 - Whisk together flour, sugar, baking powder, and salt in a large bowl until thoroughly combined.
03 - Pour the blended green mixture into the dry ingredients. Whisk gently until just combined; do not overmix as a few lumps are acceptable and prevent tough pancakes.
04 - Heat a nonstick skillet or griddle over medium heat. Lightly grease with butter to prevent sticking.
05 - Pour approximately 1/4 cup batter per pancake onto the skillet. Cook until bubbles appear on surface and edges appear set, about 2-3 minutes.
06 - Flip pancakes and cook for an additional 1-2 minutes until golden brown and cooked through. Transfer to serving plate.
07 - Serve pancakes warm, topped with additional butter and generous maple syrup drizzle.
