Preheat the oven to 350-degrees. Whisk the flour together with the kosher salt, baking powder, baking soda and cinnamon.
In a large mixing bowl, blend the sugars together then add the flour mixture and combine until well mixed about 1 minute.
Add the eggs, water, vanilla extract, and shortening and beat on medium speed until the dough is smooth, about 1 to 2 minutes.
Using low speed, stir in the oats and the raisins then beat for about 1 minute or just until the oats and raisins are mixed into the dough.
Using a small ice cream scoop or teaspoon, measure outrounds of dough onto a baking sheet lined with a Silpat liner or parchment paper.Leave about 2” between cookies to allow for them to spread while baking.
Bake in a 350-degree oven for 12 to 13 minutes, just until the cookie dough no longer looks wet and the edges start to turn golden.
Let the cookies cool on the baking sheet for about 5 minutes until they have cooled enough to set then transfer to a wire rack to cool completely.
