01 - Whisk together flour, granulated sugar, baking powder, baking soda, and salt in a large bowl until evenly distributed.
02 - In a separate bowl, blend milk, eggs, melted butter, and vanilla extract until homogenous.
03 - Pour wet mixture into dry ingredients and stir gently until just combined, leaving some small lumps. Avoid overmixing.
04 - Heat a nonstick skillet or griddle over medium heat. Lightly grease with vegetable oil or butter as needed.
05 - Pour about 1/4 cup batter per pancake into the hot pan. Use the back of a spoon to form a ghost silhouette, with a rounded top and tapering wavy base.
06 - Cook pancakes until bubbles appear on the surface and edges look set, around 2 to 3 minutes. Flip and continue cooking 1 to 2 minutes until thoroughly cooked and golden.
07 - Transfer cooked pancakes to a plate and repeat the process for remaining batter, greasing the pan between batches.
08 - Position a ghost-shaped stencil made from parchment or cardstock over each pancake. Sift powdered sugar atop the stencil, then carefully lift to reveal the ghost outline.
09 - Optionally, press small chocolate chips or mini candies into the pancake to form eyes and a mouth. Serve immediately while warm.
