I’ve always had a soft spot for oatmeal cookies. And, what’s not to like? They are soft, and chewy, with that buttery and oat taste. Oatmeal cookies are the hallmark of many childhoods.

Well, get ready because this quick oats cookie recipe is just like those cookies that your mom (or grandma) made!

Tried and True Oatmeal Cookies

This simple oatmeal cookie recipe was my mother-in-law’s. My husband says that she made cookies regularly.

In fact, we have the exact cookie jar that sat on the counter when he was growing up.

Apparently, it was a challenge for him and his younger brother to get it open and closed without anyone hearing it.

I have a large collection of old family recipes. Last year, I started organizing and testing them. And, these oatmeal cookies using quick oats were a winner!

It’s the perfect balanced mixture of buttery sweetness and it is versatile and adaptable.

Best of all is that you can add in M & M, raisins, chocolate chips, nuts, or a variety of goodies to customize this just like your grandma’s oatmeal cookies.

Tips for Making Oatmeal Cookies like your Mom/Grandma Made

  • For softer cookies just leave the dough in small balls before baking.
  • If you like chewier cookies, lightly mash the dough with a fork before baking.
  • You can use old-fashioned oats. I prefer old-fashioned oats as they have more texture and a nuttier taste. But, you can use instant oats or even a mixture of the two.
  • And, the flatter, chewier cookies are perfect for making oatmeal cookie sandwiches.

Frequently Asked Questions

Oatmeal cookies contain significant amounts of minerals like calcium, iron, magnesium, and potassium, all of which are needed for overall physical health.

To plump up the raisins, soak them in hot water before adding them to the cookie dough. Just make sure you drain them well and dry them on a paper towel so they don’t add too much moisture to the cookies.
