In a medium bowl whisk together the flour, salt, baking soda, oats and chips.
In a large bowl or the bowl of the stand mixer (with the flat beaters) beat together on medium speed the egg, butter and sugars until combined.
Add the dry ingredients to the creamed mixture with a wooden spoon or spatula. If you use a stand mixer then you could combine it on low speed. Don’t over mix though. Cover the bowl with plastic wrap and chill for 60 minutes.
Roll the dough into balls or use a large cookie scoop and place the dough balls on 1-2 parchment paper lined baking sheets.
Lightly press down on the dough with a fork dipped in flour (so the dough doesn't stick). While the oven is pre-heating chill the cookie dough balls for about 15-20 minutes.
Pre-heat oven to 400F (200C).
Bake for approximately 8-10 minutes or until golden brown. Let cool 5 minutes on the baking sheet then move to a wire rack to cool completely before serving. Enjoy!
Notes
You can make the dough and keep it in the fridge for two to three days. The longer the dough is in the refrigerator the better the flavor will be.You can substitute with raisins, be sure to place the raisin in a bowl of boiling water for about 15-20 minutes this will plump them up. The reason for this is plumping the raisins up before baking makes sure that they don’t take any moisture away from the ingredients.If you wish you could also use dark chocolate chips, milk chocolate chips or even butterscotch chips would be very tasty.The completely cooled cookies should be stored in an airtight container, they can be kept at room temperature for 5-6 days. I’m sure they won’t last that long though.Freeze the completely cooled cookies in a freezer bag or container. They will keep for up to three months in the freezer.If you wish you can also freeze the unbaked balls of cookie dough. Place the cookie balls on a baking sheet and freeze until firm, once firm transfer to a freezer bag or container.They can be baked without thawing, just bake them an extra couple of minutes. They will keep for up to two months in the freezer.
