Take a mixing bowl and beat the egg well.
Add milk and vanilla and mix well or whisk well.
Add the pancake mix and brown sugar.
Whisk all the ingredients well without any lumps.
Add melted butter and mix well.
Heat a non stick pan or a skillet.
Grease it lightly.
Pour a ladle full of batter on the centre of the hot griddle.
Cook the bottom side well on medium heat.
Flip and cook the other side too until it is perfectly cooked.
Now use different fruits, candies, nuts, seeds or cereals and make spooky or ghost or monster character appearances.
Can use sliced bananas and bluerries to make monster eyes and use cereals or big seeds to make teeth of ghost.
Use any fruits from the kitchen and get creative to give the pancakes ghostly appearance.
