I’ve always had a soft spot for oatmeal cookies. And, what’s not to like? They are soft, chewy, with that buttery and oat taste. Oatmeal cookies are the hallmark of many a childhood. Well, get ready because this oatmeal cookie recipe is just like those cookies that your mom (or grandma) made!

Tried and True Oatmeal Cookies

This 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, this cookie recipe was a winner!

First, it’s the perfect balanced mixture of buttery sweetness.

Then, it is versatile and adaptable. For softer oatmeal cookies just leave the dough in small balls before baking. If you like chewier cookies, lightly mash the dough with a fork before baking. And, the flatter, chewier cookies are perfect for making oatmeal cookie sandwiches.

Another thing that makes them adaptable is that 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.

Oatmeal cookies with M&Ms

Best of all is that you can add in M&Ms, raisins, chocolate chips, nuts, or a variety of goodies to customize them. Check out my recipes for the original M&M cookies recipe, spring sugar cookies with M and Ms, or chewy chocolate chip cookies.

These are amazing cookies! The only thing you have to worry about is making enough. So, double the recipe.

Pro Tip: You can keep the extras in the freezer for ice cream sandwiches. After baking, use a sandwich baggie or wax paper to separate the cookies, then place in a large freezer bag. They will keep in the freezer for up to 3 months.
