In a medium bowl, combine flour, sugar, salt, baking powder and cinnamon.
In a separate large bowl, beat together eggs, milk, corn syrup, butter and vanilla extract. Stir in the flour mixture.
Heat a lightly oiled griddle or frying pan over medium low heat. Pour or scoop the batter onto the griddle, using approximately 1/4 cup for each pancake. Brown on both sides and serve hot.
While pancakes are cooking, mix the icing. Combine confectioners' sugar, vanilla extract and enough milk to make a liquid frosting. Drizzle frosting on hot pancakes before serving.
