This oatmeal cookie recipe is a longtime family favorite and the only recipe I use when I want a batch of perfectly soft and chewy oatmeal cookies. It’s an easy, no-chill cookie recipe that is ready quickly.

Some of my all-time favorite recipes came from my grandparents, both sides of the family. But some of my favorite bread and cookie recipes come from the Gillan side of the family. Both my grandma and grandpa were bakers. This oatmeal cookie recipe comes from my Grandma Gillan (Erdkamp Family).

I can’t get enough of every bite of these oaty, sweet, soft, and chewy oatmeal cookies. They are best served warm with a cold glass of milk.

This is a special oatmeal cookie recipe. It’s simple, delicious, and full of love and tradition.

Recipe Highlights

  • These oatmeal cookies are made with shortening, which gives them the best texture. The shortening helps the cookies puff up a little more, and they are amazingly soft and chewy.
  • They’re easy to make, and you don’t have to chill the dough.
  • Tip no.My grandpa always made them plain, and I prefer them that way. But you can easily add things like chocolate chips, dried cranberries, and chopped nuts to them or make oatmeal raisin cookies. 3

Oatmeal Cookies Tips

  • I don’t have a shortening; can you use butter instead? Yes, you can use the same amount of room-temperature butter instead of shortening. This will alter the cookie texture a bit, but they will still be great.
  • Can you freeze oatmeal cookie dough? Yes, you can make the dough and scoop it into balls. Place them in a single layer on a cookie sheet and freeze them for 30 minutes. Once they are frozen, store them in a freezer bag. When you are ready to bake cookies, thaw the dough balls at room temperature for 10 minutes before baking them.
  • How long do oatmeal cookies keep? Store the cooled cookies in an airtight container. At room temperature, they will keep well for two to three days.
  • Can you freeze them? Yes, you can freeze the baked cookies. Keep them in a freezer-safe bag or container, and they will stay well frozen for a few months.
  • What else can you add to the cookies? Yes, you can freeze the baked cookies. Keep them in a freezer-safe bag or container; they will stay well frozen for a few months.

    1. Sorry for the confusion! The recipe calls for shortening but butter can be used in its place. I have updated to instructions to say shortening instead. Thank you for letting us know!

  1. 3 stars
    If you use butter instead of shortening, you probably need to adjust the directions to say that they do need to be chilled. Otherwise they merge into one huge flat undercooked cookie. Like mine did. (And I actually did chill them.)

    1. We have made this several times (family recipe) and haven’t had that happen, hopefully, they were good enough to eat or at least put over ice cream.

  2. these are the best oatmeal cookies I have ever had. very flavorful. I added it to my special recipe book.
