01 - In a blender, combine the milk, eggs, spinach, melted butter, and vanilla extract. Blend until the spinach is thoroughly pureed and the mixture achieves a vibrant green hue.
02 - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, and salt until well combined.
03 - Gently pour the green spinach mixture into the dry ingredients. Stir just until combined; a few small lumps are acceptable, but avoid overmixing.
04 - Heat a nonstick skillet or griddle over medium heat. Lightly grease the cooking surface with a small amount of butter or oil.
05 - Pour approximately ¼ cup of batter for each pancake onto the hot skillet. Cook until bubbles appear on the surface and the edges begin to set, typically about 2 minutes.
06 - Flip each pancake and continue cooking for an additional 1 to 2 minutes, or until golden brown and thoroughly cooked.
07 - Repeat the cooking process with the remaining batter, re-greasing the skillet as needed between batches.
08 - Serve the warm pancakes immediately, optionally topped with maple syrup, whipped cream, and fresh berries.
