Oatmeal Chocolate Chip Cookies – How to make the best oatmeal chocolate chip cookies. Made with old fashioned rolled oats, they're a little soft, a little chewy, and full of chocolatey goodness.

My oldest loves it when I make oatmeal raisin cookies like Grandma used to make. But sometimes I like to switch things up and add chocolate chips instead of raisins, making the most scrumptious oatmeal chocolate chip cookies.

These cookies are a little bit soft, a little bit chewy. And they're made with simple ingredients like buttermilk (I'll show you how to make your own), brown sugar, and old fashioned oats.

I love baking cookies because they're such an easy dessert to make. Some of my favorites are chocolate chip cookies and chewy peanut butter cookies.

Let's bake a yummy batch of oatmeal cookies right now, though. Are you ready?

My mom taught me this little trick for making buttermilk (or souring milk) back when I was a budding baker in our old farmhouse kitchen.

Just add about a tablespoon of distilled white vinegar to a cup of milk. I usually use a tablespoon for every cup of milk.

To make sure I have the right amount of liquid, I’ll pour my vinegar into the measuring cup first; then add the milk to my desired level or measurement.

Stir it and let sit for 5 to 10 minutes.

And that’s it! Before you know it, your milk will be perfectly soured just like buttermilk.

Now if you're using less milk, just use less vinegar. With this recipe, I'm using 1/4 cup milk, so I'll add about 1/2 tablespoon of vinegar to the milk to sour it.


I recommend using old fashioned oats, or rolled oats, when baking cookies, especially this oatmeal cookie recipe.

Mainly because rolled oats will lend to more of a chewy texture than quick oats. Quick oats can tend to make a cookie softer.

Baking Bites has a great article about regular vs. quick cooking oatmeal for baking. And The Kitchn has another great article explaining the difference between steel-cut, rolled, and instant oats.


Really, these are such easy oatmeal cookies to make. You basically have to mix up the dough, scoop it onto a cookie sheet, and bake.

There are a few tips I can share, though…

  • Soften the butter before you ever start. If you're like me and you forget to get it out (allllwayyyys), just pop it in the microwave and soften it up a bit.
  • Speaking of butter, use real butter. Margarine will change everything.
  • Use light brown sugar instead of dark brown. Why? Because light brown sugar makes a more raised cookie with a slightly crispy edge and soft, chewy middle. Dark brown makes a flatter cookie with a crunchier, chewier texture.

  • Use the full bag of chocolate chips. Of course, you're going to sneak a few, but don't skimp on the chocolate. It's one of those “the more, the merrier” scenarios.
  • There's really no need to chill the dough, though you can if you want. It *could* lend to an even chewier cookie.
  • When you scoop the cookies onto the cookie sheet, you'll need to press them down just a bit. You can do this with the flat bottom of a glass.

Warm cookies fresh from the oven are the absolute best, especially when you serve them up with a tall glass of ice cold milk. Yum!

One of my all time favorite recipes is an old recipe my family has made for years, Grandma's chocolate sandwich cookies. Another oatmeal cookie favorite that's also full of chocolatey goodness, is this recipe for monster cookies.

Dinner Then Dessert has a delicious recipe for super chewy oatmeal raisin M&M cookies. And Lil' Luna has an old fashioned recipe for iced oatmeal cookies.

I'm getting hungry just thinking about fresh baked cookies.

Cookie Scoop – I wasn’t sold on my cookie scoop at first; Dan wanted me to use it, but I was used to just using a spoon and my fingers. But he was right… It saves dough, makes a smaller cookie, and gives you a rounder cookie.

  1. Delicious cookies, and simple to make. Mine made 4 dozen, half to share with my daughter and son-in-law who have just had their first baby. Thanks for a great recipe!

  2. Absolutely delicious… crunchy outside and bliss inside. I added some coconut and chopped nuts but great without too!!
