Preheat the oven to 350°F.
In a medium bowl, whisk together the flour, salt, baking soda, cinnamon, nutmeg, cloves and oatmeal. Set aside.
Using a stand mixer or hand electric mixer, in a large bowl, beat the butter on medium speed with both the brown and granulated sugars until fluffy, about 1-2 minutes. Add the eggs, vanilla, and molasses, and beat again until smooth.
On low speed, mix the dry mixture into the wet ingredients just until combined. Stir in the raisins.
Chill the dough 20 minutes before baking. If not baking after 20 minutes, scoop then refrigerate or freeze the dough until ready to bake.
Using a cookie scoop or spoon, scoop out 3 tablespoon dough balls and place at least 2 inches apart on a parchment paper-lined cookie sheet.
Bake until cookie edges turn golden brown, about 13 to 15 minutes. Centers will still be slightly soft, but they will firm up as the cookies cool. Cool completely on a wire rack. Store in an airtight container at room temperature.
