In medium bowl, whisk together flour, sugar, salt, baking powder and cinnamon.
In separate bowl, whisk eggs, milk, corn syrup, butter and vanilla. Stir in flour mixture until well combined.
Heat a lightly oiled griddle or frying pan over medium heat. Pour about ¼ cup batter for each pancake and spread into desired shape. Brown on both sides (about 2 minutes per side).
Serve sprinkled generously with icing sugar or drizzled with icing - I love icing sugar, a bit of milk, and a bit of syrup mixed together. Great in a stack of two or three with icing between the layers for a full cinnamon bun effect :)
