With plenty of melty chocolate, chewy oats, and a sprinkle of sea salt, these dark chocolate chunk oatmeal cookies are guaranteed to be your new favorite cookie variety. They’re extra buttery and soft with slightly crisp edges and a touch of cinnamon and molasses for classic oatmeal cookie flavor. This cookie has it all!

Alright, I’m saying it. Oatmeal cookies are forever the best cookie on the planet. (This statement probably doesn’t surprise many of you!) Regular chocolate chip cookies are a bonafide crowd-pleaser, but they don’t hold a candle to the texture, chew, and toasty flavor of its oatmeal counterpart.

I originally published these dark chocolate chunk oatmeal cookies several years ago and after making them at least 1200x, I decided to spruce up the photos and make a couple slight changes to the dough including using more oats, less flour, and a sprinkle of sea salt. We’re still using plenty of dark chocolate chunks, whole oats, and a touch of molasses for classic flavor. (See recipe notes below for the exact changes.)

The Best Oatmeal Cookie Base

If you’ve made some of my oatmeal cookie recipes before, you’re likely familiar with today’s variation. I usually stick to the same base recipe and you can see that in my Oatmeal Raisin CookiesWhite Chocolate Chip Cherry Oatmeal Cookies, Oatmeal Chocolate Chip Cookies, Oatmeal Scotchies, and Oatmeal M&M Cookies.

Have I mentioned I love oatmeal cookies?

Filled with brown sugar, cinnamon, butter, and vanilla flavors, this oatmeal cookie is ALWAYS a guarantee in both the texture and flavor departments. I’ve actually nicknamed them my “slow bend” cookies– the centers are so buttery and chewy that they don’t crunch and break when you start to bend them. The best!


How to Make These Dark Chocolate Chunk Oatmeal Cookies

  1. Cream butter + sugars: Use a hand or stand mixer to cream softened butter with brown sugar and granulated sugar until smooth. For extra flavor and chew, always use more brown sugar than granulated white sugar in oatmeal cookies.
  2. Add eggs, vanilla, + molasses: Add eggs, then mix on high for about 1 minute until incorporated. Add vanilla and molasses, mix until combined.
  3. Dry ingredients: Mix flour, baking soda, cinnamon, and salt together in a separate bowl. Pour this into the wet ingredients. Combine together on low.
  4. Add the extras: Beat in the oats and chocolate chunks on low speed. Pieces of chocolate will break down, so there’s chocolate in literally every single piece of cookie dough.
  5. Chill: The cookie dough is pretty sticky, so chilling it is imperative. Without at least 30-60 minutes in the refrigerator, your cookies will spread into flat puddles. Chilling cookie dough is one way to guarantee thicker cookies. If you’re interested, see my 10 guaranteed tips to prevent cookies from spreading.
  6. Roll: Roll cookie dough into balls and place on a lined baking sheet. Since it’s a textured and chunky dough, I usually use a cookie scoop to help. Since the cookie dough chilled, it’s much easier to work with.
  7. Bake: Bake the cookies at 350°F (177°C) until lightly browned around the edges. The cookies might look under-baked, but they will continue to set as they cool. While they’re still warm, sprinkle each with a little sea salt.

Best part: Right out of the oven, experience pools of melty chocolate in every single bite.

Best Chocolate To Use

There are so many chocolate products on the market, so let me help you navigate the best choice for today’s cookies. As if you were making chocolate truffles or chocolate ganache, stick to pure quality chocolate here. I’m referring to baking chocolate, which is sold in 4 ounce bars in the baking aisle. Chocolate chips definitely work since these are cookies, but if you want big chunks of melted chocolate, choose chocolate that’s meant to melt. Chocolate chips contain stabilizers that prevent them from melting in the oven.

I recommend bittersweet or semi-sweet chocolate. For a sweeter cookie, you can use white chocolate or milk chocolate. I prefer Ghirardelli or Baker’s brands. (FYI Baker’s milk chocolate variety is sold as “German Chocolate.”)

  • No matter which level of sweetness you choose, cut the bars into little chunks that are similar or slightly larger than regular chocolate chips. But keep in mind that the smaller the pieces, the more they’ll blend right into the cookie dough turning this into a chocolate oatmeal cookie… which isn’t necessarily a bad thing!

Dark Chocolate Chunk Oatmeal Cookies

  • Author: Sally
  • Prep Time: 45 minutes
  • Cook Time: 12 minutes
  • Total Time: 1 hour
  • Yield: 3 dozen
  • Category: Cookies
  • Method: Baking
  • Cuisine: American

Description

Soft and chewy with slightly crisp edges, these oatmeal cookies are full of flavor and exploding with melty dark chocolate. Chill the dough for at least 30 minutes in the refrigerator before baking.


Ingredients

  • 1 cup (230g) unsalted butter, softened to room temperature
  • 1 cup (200g) packed light or dark brown sugar
  • 1/4 cup (50g) granulated sugar
  • 2 large eggs, at room temperature
  • 1 Tablespoon pure vanilla extract (yes, Tablespoon!)
  • 1 Tablespoon molasses
  • 1 and 1/2 cups (188g) all-purpose flour (spoon & leveled)
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 3 cups (240g) old-fashioned whole rolled oats*
  • two 4-ounce semi-sweet chocolate bars, chopped (1 and 1/2 cups)*
  • optional: coarse sea salt for topping

Instructions

  1. 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, about 2 minutes. Add the eggs 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.
  2. In a separate bowl, whisk the flour, baking soda, cinnamon, and salt together. Add to the wet ingredients and mix on low until combined. Beat in the oats and chocolate on low speed. Dough will be thick, yet very sticky. Chill the dough for 30-60 minutes in the refrigerator (I always chill this dough for only 30 minutes). If chilling for longer (up to 2 days), allow to sit at room temperature for at least 30 minutes before rolling and baking. The cookies won’t spread as much if chilled for longer than 1 hour.
  3. Preheat oven to 350°F (177°C). Line two large baking sheets with parchment paper or silicone baking mats. Set aside.
  4. Roll balls of dough (about 1 and 1/2 Tablespoons of dough per cookie) and place 2 inches apart on the baking sheets. I recommend using a cookie scoop since the dough can be sticky. Bake for 11-12 minutes or until lightly browned on the sides. The centers will look soft and under-baked. Remove from the oven, immediately sprinkle each with sea salt (if using), then let cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely. The cookies will continue to “set” on the baking sheet during this time.
  5. Cover and store leftover cookies at room temperature for up to 1 week.

Notes

  1. Make Ahead & Freezing Instructions: Baked cookies freeze well up to three months. Unbaked cookie dough balls freeze well – up to three months. Bake frozen cookie dough balls for an extra minute, no need to thaw. Here’s how to freeze cookie dough.
  2. Oats: For these oatmeal cookies, I use and recommend old-fashioned whole oats. They provide the ultimate hearty, chewy, thick texture we love!
  3. Eggs: Room temperature eggs preferred. Good rule of thumb: always use room temperature eggs when using room temperature butter.
  4. Chocolate: Though chocolate chips work just fine, if you want big chunks of melty chocolate, use pure baking chocolate. See Best Chocolate to Use in the blog post above. I prefer semi-sweet or bittersweet chocolate here. Chop chocolate into chunks around the same size or slightly larger than chocolate chips.
  5. Be sure to check out my top 5 cookie baking tips AND these are my 10 must-have cookie baking tools.
  6. Adapted from Loaded Oatmeal Cookies (The original recipe base. If you’d like to make them that way, follow that recipe and use 1 an 1/2 cups chopped chocolate instead of the listed multiple add-ins). Recipe originally published on Sally’s Baking Addiction in 2015.

  1. Just going to try for the first time. Can I use salted butter as that is all I have?

    1. Trina @ Sally's Baking Addiction says:

      Hi Taylor! Yes, you can use salted butter. Reduce the salt to 1/4 tsp.

  2. Mine almost didn’t spread.
    Stayed dome shaped.
    What did I do wrong?

    1. Lexi @ Sally's Baking Addiction says:

      Hi Jenny, when cookies aren’t spreading, it means that there’s too much dry ingredient (flour) soaking up all the liquid. Did you use the spoon and level method to measure? We share more on what to do if your cookies aren’t spreading in these 5 tips to improve your next batch of cookies — jump down to #2 and the subhead “What to do if your cookies AREN’T spreading?” for more. Hope this helps!

  3. I used a scale.
    They are still yummy.
    Could it be because I used quick oats?

    1. Stephanie @ Sally's Baking Addiction says:

      Quick oats will dry out the cookie dough and the cookies won’t spread as much. If you decide to try them again, you can skip the cookie dough chilling and expect a little less texture in the finished cookies.

  4. These cookies were really delicious! I made them smaller because I don’t like really big cookies, so they turned out harder, but were still very tasty! Also very easy to make

  5. Hi Sally,
    Am I able to make these without the egg or substitute something else. Going to use dark chocolate, vegan butter and try and make them vegan.
    Thank you

    1. Trina @ Sally's Baking Addiction says:

      Hi Sabrina, we haven’t tested this recipe with an egg substitute but let us know if you give it a try!

  6. If I don’t have a hand mixer or a whisk can I mix everything with a wooden spoon

    1. Trina @ Sally's Baking Addiction says:

      Hi Holly, you can certainly mix it by hand, but it will take quite a bit of arm muscle! Particularly when it comes to properly creaming the butter and sugars. Let us know how they turn out for you.

  7. Hi! Keen on trying out the recipe but i’m worried the molasses we bought online was the wrong type— is it ok to use Blackstrap molasses for this recipe? (Brand we bought was the Green Earth Organic Blackstrapped Molasses)

    1. Lexi @ Sally's Baking Addiction says:

      Hi Toni! Blackstrap molasses can be quite intense — we don’t bake with it often. Although since it is such a small amount in this recipe, it should be okay if you don’t mind a stronger molasses taste. You can also simply omit the molasses if you’d prefer. Hope you enjoy these cookies!

  8. Baked them for exactly 11 minutes, with parchment paper in a heavy pan. Cookies were BURNED on the bottom. I am DONE with these websites with recipes from wannabe cooks.

    1. I’ve had excellent results from many of Sally’s recipes. Could be a user error 🙂

    2. proper baking requires checking the oven and rotating the pans for even cooking. Also what shelf of the oven you bake them on and some ovens have hot spots. Burning cookies is USER ERROR AND NOT THE ERROR OF THE RECIPE DEVELOPER

  9. Hi,
    lots of great tips in your blog! The measurements (cups vs. grams) seem really off in this recipe.

    1. Trina @ Sally's Baking Addiction says:

      Hi Monica! I just double checked all the gram measurements and they look correct. Here’s a helpful post on measuring baking ingredients that includes a standard measurement chart with weights towards the end. Thank you so much for your comment!
