01 - Combine milk and spinach in a blender. Blend until completely smooth and vibrant green, ensuring no leafy pieces remain.
02 - Add egg, melted butter, and vanilla extract to the spinach mixture. Blend briefly until fully incorporated.
03 - Whisk together flour, sugar, baking powder, baking soda, and salt in a large bowl until evenly distributed.
04 - Pour the spinach mixture into the dry ingredients. Stir gently with a spatula until just combined—small lumps are acceptable. Do not overmix.
05 - Heat a nonstick skillet or griddle over medium heat. Lightly grease with additional butter.
06 - Pour 1/4 cup batter per pancake onto the skillet. Cook for 2-3 minutes until bubbles form on surface and edges appear set. Flip and cook 1-2 minutes until golden and cooked through.
07 - Repeat with remaining batter, adding more butter as needed. Serve warm with maple syrup, fresh berries, or Greek yogurt.
