Notes

Do not substitute old fashioned oatmeal for instant oats. The two are not interchangeable and will not bake properly if using the latter. 
Use light brown sugar for a less intense brown color and milder flavor. 
Try making smaller dough balls to make more cookies. 
Should you soak raisins before baking cookies?
To make plump raisins, soak them in water before adding to the cookies. I only do this when the raisins look dry or are older. 
Why do my oatmeal raisin cookies get hard?
Overmixing causes cookies to get hard. Try mixing with a wooden spoon instead of a hand mixer or a stand mixer.
How to Freeze the Cookie Dough:
Chill for 1 hour in the fridge. Then wrap in plastic wrap and place inside a freezable bag. Remove as much as possible. Store for up to 3 months in the freezer. Bake as normal. 
Storing:
Store cookies 3-4 days in an airtight container at room temperature. To store in the freezer, place in a freezer bag and remove as much air as possible. They store well for up to 3 months in the freezer. Thaw for 1-3 hours before consuming.
