Super Easy Oatmeal Cookies Recipe

When most people have a craving for cookies, they want them within the hour. Not hours or even days later. And they don’t want to dirty a million dishes or drag out a (stand) mixer in pursuit of their cookie goal.

Enter: this incredibly fast and easy oatmeal cookie recipe that produces cookies that turn out perfectly thick with soft centers and chewy edges. Just add everything to one bowl, stir by hand with one spoon, and you’re ready to bake. 

While I’m normally a huge advocate of chilling cookie dough to avoid cookies that spread or are thin, you don’t have to with these simple oatmeal cookies. Not having to chill the dough makes these 20-minute oatmeal chocolate chip cookies. From the time you’re struck with a cookie craving until the time you’re eating said cookies, it’s 20 minutes.

What’s in Homemade Oatmeal Cookies? 

For these homemade oatmeal cookies, you’ll need: 

  • Egg
  • Unsalted butter
  • Light brown sugar
  • Granulated sugar
  • Vanilla extract
  • Old-fashioned oats
  • All-purpose flour
  • Baking soda
  • Salt
  • Semi-sweet chocolate chips

How to Make Oatmeal Cookies

When I say easy oatmeal cookies, I mean EASY oatmeal cookies! Simply stir together the egg, butter, sugars, and vanilla and stir vigorously to combine (your bicep should be burning). Mix in the dry ingredients, then gently fold in the chocolate chips. 

Scoop the cookie dough onto a baking sheet and bake for roughly 10 to 13 minutes. If you prefer softer homemade oatmeal cookies, bake for less time, and if you prefer more well-done cookies, bake for a little more time. 

Let your simple oatmeal cookies cool for a few minutes before transferring them to a wire rack. They need a little time to cool and set up before you can dunk them into milk!

Can I Use Quick Oats in These Oatmeal Cookies? 

No, quick oats have a much different texture than rolled oats and would act more like a flour in these cookies. Your homemade oatmeal cookies would wind up being too dry. 

Can I Add Extra Mix-Ins? 

Of course! I added chocolate chips to keep these simple oatmeal cookies, but you can add raisins, walnuts, or whatever you love in oatmeal cookies.

Can I Freeze Oatmeal Cookies? 

Yes, you can freeze both the cookie dough (after it’s been rolled into balls) or the baked oat cookies. Frozen cookie dough doesn’t need to be thawed before being baked, but it’ll need an extra minute or two in the oven to cook through. And if you freeze the baked cookies, you can reheat them in the oven or the microwave when you’re ready to enjoy them.

Tips for Making the Best Oatmeal Cookies

Since you’re beating the dough together with elbow grease, I highly recommend having the butter and egg at room temperature. The softer the butter is, the easier your job will be. Of course you can use an electric mixer, but that defeats the purpose of as few dishes and as easy as possible.

Didn’t plan ahead for room temp ingredients? No problem. Pop your butter in the microwave for 10 seconds or until it’s just barely showing signs of melting. Add the egg to a bowl of very hot water for a couple minutes. A warm egg emulsifies easier than a cold one.

I highly recommend using a cookie scoop as well. The dough is soft, warm, and the domed shape a scoop produces is essential to preventing excess spreading. Same goes for a Silpat, use one.

Easy Oatmeal Cookies

FAST and EASY oatmeal cookies that are perfectly thick with chewy edges and soft centers! One bowl to wash, no mixer to drag out, and no waiting around!

Prep Time 10 minutes
Cook Time 10 minutes
Total Time 20 minutes

Ingredients

  • 1 large egg
  • 1/2 cup unsalted butter (1 stick), very soft
  • 1/2 cup light brown sugar, packed
  • 1/4 cup granulated sugar
  • 2 teaspoons vanilla extract
  • 1 1/2 cups old-fashioned whole rolled oats (not instant or quick cook)
  • 3/4 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt, or to taste
  • 1 cup semi-sweet chocolate chips, plus more for after baking (or substitute with raisins, walnuts, etc.)

Instructions

    1. Preheat oven to 350F, line a baking sheet with a Silpat or spray with cooking spray; set aside.
    2. To a large bowl, add the egg, butter, sugars, vanilla, and mix with a spoon aggressively for about 90 seconds, or until smooth and slightly fluffed, i.e. your bicep and shoulder should be burning if you’ve mixed well enough.
    3. Add the oats, flour, baking soda, salt, and stir to combine.
    4. Add the chocolate chips and stir to combine.
    5. Using a 2-tablespoon cookie scoop, form mounds and place on prepared baking sheet spaced about 2 inches apart (I baked 12 cookies on the first sheet)
    6. Bake for about 10 to 13 minutes (short for super soft cookies, longer for more well-done cookies), or until edges have set and tops are just set, even if slightly undercooked, pale, and glossy in the center; don’t overbake. Cookies firm up as they cool.
    7. Immediately upon taking the baking sheet out of the oven, add about 5 additional chocolate chips per cookie. Allow cookies to cool on baking sheet for about 10 minutes before serving. I let them cool on the baking sheet and don’t use a rack.

Notes

Cookies will keep airtight at room temperature for up to 1 week or in the freezer for up to 6 months.

Alternatively, unbaked cookie dough can be stored in an airtight container in the refrigerator for up to 5 days, or in the freezer for up to 4 months, so you may consider baking only as many cookies as desired and save the remaining dough to be baked in the future when desired.

  1. Really delicious. My kids loved them too. I do think one cup chocolate chip is too much. I will half it next time.

    1. Thanks for the 5 star review and I’m glad this was delicious and your kids loved them! Of course, always scale the amount of chips to your tastes preferences.

  2. Delicious. I know it say no quick oats but it was all I had. I’m sure the texture is different but still yummy. I did not put chocolate chips but did add pecans and cinnamon. I love oatmeal cookies with cinnamon.

  3. AND NO COOLING RACKS TO CLEAN⁉️‼️❣️   Made these today exactly as written. They rock! You rock! Going to wash my one mixing bowl and measuring things while they cook some more On The Baking Sheet😁

    1. Thanks for the 5 star review and glad you these were a winner for you and correct, no cooling racks to clean either!

  4. Good, but two teaspoons of pure vanilla extract  is overwhelming.  Will try again with just one.

    1. For me 2 teaspoons is nothing :) I could easily use a tablespoon! But we all have different tastes. Glad you enjoyed the cookies overall and will try them again.

  5. Maybe I’m missing something, but I’m not seeing HOW MUCH of each ingredient so can’t make the cookies.

    1. You probably need to scroll down a bit further than you were, but not all the way down to the comments. There is a recipe card section.

  6. Holy cow! I just wanted some quick cookies. I thought for sure these were going to be mediocre at best, but at least they’d scratch that impulsive itch… Boy was I wrong!!! These are quite possibly the best cookies I’ve ever had and certainly the best I’ve ever made. I did NOT expect to love these as much as I did.  I followed the recipe to a tee. The only change I made was using half a cup of mini semi sweet chocolate chips and half a cup of an omega 3 nut blend (walnuts, almonds, pecans, pepitas, dried cranberries) that I gave a quick rough chop in the food processor. They turned out amazing! They’re thick with a soft, chewy texture and course crumb.  They’re very hearty and satisfying. Only 2 cookies will fill you up. Excellent if you’re like me and lack all self control around less satiating cookies. All the fiber in the cookie makes it definitely feel like a more nutritious but equally delicious option! This is going to be my go to cookie recipe from now on. Just incredible cookies. Taste like something you’d pay top dollar for.

  11. Averie, I love your recipes and look for them everyday in my email. I haven’t made this cookie recipe yet, but the ingredients and the method look right and others have given their enthusiastic approval. I know I will cook them a little longer than you do as I like crunchy chocolate chippers. I like to add pecans (lots of them) and dried cranberries soaked for an hour in white wine or orange juice (plan ahead). I just wanted to say, thanks for all your hard work. It is much appreciated.

  12. Cookies always burn on the bottom and edges before they’re done in the middle. How do I fix this?

  13. Thank you soooo much for this recipe! It’s simple and honest (I think my arm nearly fell off) but apparently I did it right because they are deeee-lish! I did tweak it a bit…I used almond extract instead, and doubled the recipe. Then I halved it, and added pecans to both, and cranberries (to one) and mini chocolate chips to the other. Plus…a lil canna oil was added to the wet ingredients…I’ve already saved this recipe, and even added it to my will. LolThank you Averie!

    1. Thanks for the 5 star review and I am glad you love the recipe and have tweaked it to your liking!

  14. Made these because I love your snickerdoodle recipe and I’m obsessed. I add a dash of cinnamon and they are heavenly! I make these almost every week and they’ll stay fresh in an airtight container for a long time. Love your blog and can’t wait to try more recipes!!

    1. Thanks for the 5 star review and glad these are a weekly favorite! Thanks for being a supporter of my site and actually making the recipes, too!

  15. These cookies are so amazing – great flavour and perfect texture! The best part is that it is so easy to make and everything is done in one bowl (well, two because I did microwave the butter to soften it). I will definitely be making them again.

  16. This is THE best oatmeal cookie recipe, hands-down. I’ve tried multiple, other top-rated recipes — all of them require the annoying “mandatory refrigerator chill-time” and not one of them compares to the softness and flavor of these cookies. This recipe yields the perfect-size batch for a small family (approximately 10-12 medium cookies) – sometimes I even half it (use only one egg yolk) when I’m trying to be extra-good, because honestly these cookies are delicious and comforting I could eat all of them in 1-2 days. I like to add approx. 3/4 cup chopped walnuts — and if I’m feeling really decadent, I substitute the chocolate chips for 1/2 cup mini chocolate chips and a full cup of peanut butter M&Ms. Thank you, thank you for such a *perfect* recipe.

    1. Thanks for the 5 star review and I am glad you love all the aspects of this recipe from the no chill time to small batch and you think they’re perfect!

  17. I read all the other comments and apparently I am the only one for whom these cookies did not turn out!🙁 I did everything according to the recipe except I used a handheld mixer for the wet ingredients because I just couldn’t get it incorporated properly by hand. They seemed a bit wet when I put them on the sheet, and sure enough they completely flattened out in the oven and now look like a huge soggy rectangle! I don’t know what happened…any thoughts?

    1. It sounds like yes, the dough was too wet. Sounds like you perhaps used too much butter, too little dry ingredients, an XL egg, there are quite a few things that could have gone wrong but it’s hard to tell from afar. Thanks for trying the recipe.

  18. Hi Averie. I know you said to use rolles oats, but I don’t have ‘em at the moment. I used quick cooking oats, but reduced the flour by 1-2 tbsp. and they turned out great. Will definitely make them again.  :)

    1. Thanks for the 5 star review and glad that rolled oats with reduced flour worked just fine and they turned out great!

  19. Hey Averie! I love your website and I love the simple yummy recipes you make. I wasn’t sure if it would take only 20 minutes from prep to taste to make this recipe, but it was awfully close. They came out soft and chewy and just the perfect sweetness. My little one gives it a thumbs up!

  21. Made this today… left out the 1/4 cup of white sugar and added 1/4 tsp of cinnamon. So good! Love that this recipe can be used as a base recipe too.

    1. Thanks for the 5 star review and glad you didn’t need the white sugar and yes it’s a nice versatile recipe to use as a cookie base to then incorporate other add-ins.

      1. Oh, my these are so good… some of them made it to the oven, but I was happy just eating the dough too 😆

      2. Thanks for the 5 star review and glad that you loved them, both before and after the oven :) that’s just how I am too!

  22. Amazing recipe!!!!! The cookies turned out GREAT!  Although I cooked them for longer coz my family prefers crunchier cookies – about 15mins for each batch! And I used quick oats for it coz that’s what I had in my kitchen. This makes me try more of your recipes especially since I’ve had soo many baking fails this week!

  23. Made these last night and they were AMAZING! I froze some of the cookie dough to bake off later … but I think I’m going to have to bake the rest of the cookies this week because I have zero self-control. I love that this is an oatmeal cookie dough rather than a cookie dough with oatmeal in it — you know what I mean? You really packed in the textures and flavors with this recipe. Seriously the best oatmeal chocolate chip cookies I’ve ever made. I will definitely be making these again!!

    1. Thanks for the 5 star review and glad they turned out amazing! I am glad to hear they are the best oatmeal cookies you’ve ever made, wow thank you!

      And yes, I am all about REALLY have the dough be oatmeal-based not just as you said (perfect analysis) some cookie dough with a little oatmeal throw in. I love all that heartiness so am all about the oats front and center!

  24. I made the chocolate chip oatmeal cookies one bowl cookies and they were amazing. My daughter who is very careful about what she eats absolutely loved them. My grandchildren even called me and asked me to make more. The whole conversation was about the cookies. I substituted raisins in another batch as my son doesn’t like chocolate and they were a hit as well. So glad I found your site.
