In a large pan, add butter and melt on medium heat until it begins to get golden and brown slightly.

Add the brown sugar, corn syrup, water, cinnamon and salt and bring mixture to a simmer.

When the brown sugar dissolves and the mixture thickens slightly, add the quick oats and pecans (if using) and stir until all the oats are coated.

Spoon mixture into individual cookies on a piece of parchment paper, sprinkle the tops with salt.

Allow to cool completely before enjoying.
