A lot of readers ask me… what’s your favorite basic cookie recipe? Well, I have a few.

For super soft & thick, try my chocolate chip cookies and add in whatever you like! For extra chewy, try my chewy chocolate chunk cookies. For sugar cookies – bake these, for chocolate cookies – I suggest these, for peanut butter cookies – use this recipe, and for snickerdoodles – bake these in only 20 minutes.

But for oatmeal cookies? You’re looking at them.

My favorite oatmeal cookie couldn’t be any more straightforward and simple. They’re soft, they’re chewy, kissed with molasses flavor, and ready for any add-ins your tastebuds desire. I typically make them with raisins and/or M&Ms – published here.

Those photos were updated recently – that’s how often I make these oatmeal cookies!

 

☆ Cookie science talk ahead.  Aka nerd alert.

My oatmeal cookie dough starts with creamed butter, brown sugar, and granulated (white) sugar. It’s important to know that sugar is used to not only sweeten the cookies, but to give them structure, texture, tenderness, and volume. In most of my cookie recipes, I prefer to use more brown sugar than white sugar. This is because brown sugar holds more moisture than white sugar and thus will produce a softer, moister final baked good. I like to use dark brown sugar since it has a slightly higher amount of molasses. However, if you’re in a pinch and only have light brown sugar – that’s ok!

I recently began adding a Tablespoon of dark molasses into my oatmeal cookie dough. It’s a little something I picked up from one of my cookbook cookie recipes (recipe on page 109!). 1 Tablespoon doesn’t sound like much. And you’re right! It’s not that much. But it’s just enough to give a subtle amount of extra molasses flavor. However, don’t go buy a bottle just for this recipe. They’re fine without it.

I played around with the oats to flour ratio a lot when I first published this oatmeal cookie recipe. I’ve found that more oats to flour is what I like best. I want my oatmeal cookies to taste, for lack of better words, oat-y! Oats provide a fabulously chewy texture and soak up moisture from the cookie dough and hold onto it while the cookies bake in the oven. Similar to how oats soak up all the moisture when you are making oatmeal for breakfast. This is a good thing!

There is always the question of which type of oats to use in recipes. For these? I use old-fashioned whole oats in this recipe, as opposed to quick oats. Quick oats, which are more powdery than whole oats, may dry out your cookies.  You could certainly try using them, but I prefer whole oats. They give more texture: hearty, chewy, thick.

I’ve learned over the past year how important it is to use room temperature eggs when using room temperature or melted butter in cookie recipes. Room temperature eggs incorporate evenly into your cookie dough – guaranteeing a uniform structure among every cookie in your batch. That’s why you use eggs in cookies – for structure.

Tip: When I need room temperature butter for creaming, I set out the egg(s) with the butter about 1 hour before beginning. If you forget to set out your egg, no worries. Place it into a bowl of warm water for 5 minutes, then use.

This thick cookie dough can hold a lot of add-ins. I chose peanut butter M&Ms, butterscotch morsels, and chocolate chunks. I couldn’t think of a better combination! If you have it in your pantry, throw it in. I was going to add a few pecans, but I know many people aren’t as “nuts” about nuts in their cookies as I am. Whatever goodies you choose, try to stick to about 1 and 1/2 cups total add-ins.

The cookie dough is only slightly sticky. And you know what I always do with sticky cookie dough right? I chill it. Sticky cookie dough = spreading. You’ll want these cookies to spread, but not overspread into flat discs on your baking sheet. So, chill the dough for about 30 minutes. Just enough time for you to clean up and pre-heat the oven.

I like to use a cookie scoop for oatmeal cookies. It grabs onto the textured cookie dough better than my hands can. Here is the cookie scoop I use (I own it in sizes medium and large – I used size medium for these cookies).

Scoop/roll 1.5 Tablespoons of dough per cookie. Press a few extra add-ins directly into the tops of the cookie dough balls. Why do I suggest that? It guarantees you’ll have a few pretty chunks on top of your baked cookies. Here a few cookie dough balls… you can see I pressed some broken peanut butter M&Ms into the tops.

Bake the cookies until they are lightly browned on the edges. This could be 10 minutes in your oven or 12 minutes in your oven. It’s about 11 minutes in my oven. The centers are slightly underbaked, but will set up as you let the cookie cool.

If your self control allows that… ;)

Dunk them in milk, crumble them on ice cream, bring them to friends, bake them for the kids, whatever you do with them – I know they’ll soon be a cookie jar favorite. Who doesn’t love an old-fashioned, super soft and chewy oatmeal cookie?

I hope you love my favorite loaded oatmeal cookies! And that you learned a few things along the way today. Let me know what goodies you throw into them!

A few suggestions:

  • Peanut butter M&Ms + butterscotch + chocolate chips/chunks (pictured today)
  • Raisins + chopped pecans/walnuts + dark chocolate chunks
  • Peanut butter chips + chocolate chips
  • Chopped Snickers + peanuts
  • Pretzel pieces + chopped peanut butter cups
  • Dried cranberries + white chocolate

Loaded Oatmeal Cookies

Soft-baked, ultra chewy, and simple oatmeal cookie recipe. Load them with your favorites!

Yield: 18 COOKIES

Prep Time: 10 minutes

Total Time: 50 minutes, includes chilling

Ingredients:

  • 1/2 cup (115g) unsalted butter, softened to room temperature
  • 3/4 cup (150g) dark brown sugar (or light brown)
  • 1/4 cup  (50g) granulated sugar
  • 1 large egg, at room temperature
  • 2 teaspoons vanilla extract
  • 1 Tablespoon (20g) dark molasses
  • 1 and 2/3 cups (140g) old-fashioned rolled oats
  • 1 cup (125g) all-purpose flour, careful not to overmeasure
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 and 1/2 cups add-ins (I used butterscotch morsels, chopped peanut butter M&Ms, and chocolate chunks)

Directions:

Using a hand mixer or a stand mixer fitted with paddle attachment, cream the softened butter and both sugars together on medium speed until smooth. Add the egg and mix on high until combined, about 1 minute. Scrape down the sides and bottom of the bowl as needed. Add the vanilla and molasses and mix on high until combined. Set aside.

In a separate bowl, toss the oats, flour, cinnamon, baking soda, and salt together. Add to the wet ingredients and mix on low until combined. Fold in the add-ins. Dough will be thick. Chill the dough for at least 30 minutes in the refrigerator.

Preheat oven to 325F degrees. Line two large baking sheets with parchment paper or silicone baking mats.

Roll balls of dough (about 1.5 tablespoons of dough per cookie) and place 2 inches apart on the baking sheets. I pressed a few extra M&Ms into the tops of the cookies for looks. Bake for 10-11 minutes until very lightly browned on the sides. The centers will look very soft. Remove from the oven and let cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Cover cookies and store at room temperature for up to 1 week. Baked cookies and rolled cookie dough freeze well, up to 3 months.

    Hello , I’m currently on a no white carbs diet and was wondering if I could somehow replace the flour with either coconut cornstarch and wholewheat bread flour somehow and if so then how could Ido that ? It would be very helpful and also would they still taste similarly ,? I really want to make these tomorrow so hopefully I’ll get an answer :)

    I don’t even like oatmeal cookies but I LOVED these! I put raisins and mini M&Ms in mine. The best was right out of the oven and into a bowl of blue bell homemade vanilla ice cream! Huge hit with the entire family too!

      Yes! These are so, so good with ice cream. And I can only imagine how amazing the combo of raisins and mini M&Ms is. Love oatmeal raisin cookies!

    I just had to leave a comment after baking these cookies! I’m from the UK, and I often find that baking cookies with US recipes leaves me with a cookie sheet that’s cooked into one cookie lump! Not so these! (I suspect your measurements helped!) I even substituted the all-purpose flour for the gluten free version, and it’s worked just fine, so your recipe gets the thumbs up from me! (I’m not GF, but one of my best friends is coeliac – she does eat oats, I checked) I used crunchy M&Ms, milk chocolate chips and a few sultanas in mine. I can’t wait to see how they taste! (They are cooling downstairs as I type.) Thank you for a wonderfully easy recipe!

    Hello,
    I’d like to add mashed bananas. Is there any alteration in the recipe that I should consider since I’ll be adding a wet ingredient?

    Thanks!

    I made these a couple days ago (GREAT by the way) and my dough wasn’s sticky at all. If this happens again, should I still chill the dough in the fridge?

      Yep! Chilling is always a good idea.

    Hey Sally,

    I’ve made a WHOLE BUNCH of your recipes and they’re ALWAYS a hit. I’ve made these before but this time, I’ll be pressed for time. Can I chill them for longer than 30 minutes? Thinking I’m going to make them tonight and then bake tomorrow, will that be fine?

    Cheers!

      Hi Ashley. Yes, you may chill this cookie dough for longer. Take it out of the refrigerator and let sit at room temperature for at least 30 minutes before rolling and baking.

    Hi Sally,

    Can your trick of adding an extra egg yolk, using melted butter, and corn starch be used to add extra chewiness to the oatmeal cookies in the same way as in your extra chewey chocolate chip cookies?

    PS: i tried the recipe for the snickers chocolate chip cheese cake bars last weekend…awesome :-)

      Definitely! These cookies are already ultra chewy. With an extra egg yolk here, I recommend chilling the cookie dough for closer to 1 hour since the dough will be a little more moist.

        Tried it and it worked out as I’d hpoed for, they became ultra chewey. I added so much goodies inside that they became a tad rich, but noone complained. For the chewey hocolate chip cookies I substituted 125 grams of the choccolate chips with salted pistacchios….it’ a winner with the salty crunchy addition.
        I’d like to add that I had to experiment with cooking time, as three tablespoon size cookies didn’t finish in 10 or 12 minutes for that matter, because they didn’ completely “melt” down. 325 F turned out to be insufficient in my oven. It equates to ca 163 degrees centigrade (as european ovens are scaled to), but I found upping the temp to 180 C or 356 F for 12 minutes did the trick for the bigger size cookies. I also found it easier to size the cookies evenly by rolling the dough into a “salami thick sausage” shape in cling wrap, and then to cut it in even sizes with a sharp knife, since trying to use a spoon on the chilled cookiedough was nigh on impossible…

    So yummy!! I am obsessed with your cookie recipes because they’re always prefectly chewy. You definitely take the time to perfect each recipe and I greatly appreciate it because I know nothing about cooking!!! Also, I added butterscotch and coconut. Coconut makes it extra chewy mmm!

    Good Gracious, these are AMAZING! I know you disrecommended any alterations but I’m vegan. . . so. . . I went all Post Punk Kitchen on this recipe and substituted ground flax seed for the eggs (which, btw, lent an absolutely extraordinary slightly nutty flavor), and Earth Balance Vegan Buttery Baking Sticks for the butter. Man oh man did they ever knock our socks off! Just the chewy deliciousness I was hoping for. Thank you!
