There are days when I want a cookie, and then there are days when I want a very specific kind of cookie. Something a little hearty and a little chocolatey usually does the trick. And that’s when I end up making these oatmeal dark chocolate chunk cookies.

I didn’t set out to reinvent the oatmeal cookie here, I just wanted one that felt a little more like something you’d grab from a bakery than something I whipped up in my little kitchen on a whim. You know what I mean, soft in the middle, a little crisp around the edges, and full of those uneven chunks of dark chocolate (instead of perfectly placed chocolate chips).

Now this is my favorite one. The cookies are simple, they use what I already have, and they always turn out better than they probably should, haha.

Why You’ll Love These Dark Chocolate Oatmeal Cookies

These cookies have the perfect chewy oatmeal cookie texture. The mix of brown sugar and regular sugar gives you that soft center with lightly crisp edges, while the oats add that hearty texture we all love in an oatmeal cookie. They’re easy, reliable, and don’t require any chilling. Just mix, scoop, and bake (always a win in my book).

Ingredient Notes

• The combination of brown and white sugar gives you the best texture, chewy centers from the brown sugar and slightly crisp edges from the white sugar. You can use either light or dark brown sugar, but I think dark adds a deeper flavor and more chew, so that’s what I usually grab.
• Old-fashioned oats are the move here. They give the cookies that hearty, chewy texture. Quick oats will work in a pinch, but the cookies will be softer and less defined.
• Chop a dark chocolate baking bar if you can. You’ll get better melt, better distribution, and those bakery-style pockets instead of uniform chips. If you want to use chips instead, they’ll work fine, but the cookies may be lumpier.
• The cinnamon is meant to enhance the cookies not take over, so start with 1/2 teaspoon. If you like a little more warmth, you can take it up to 1 teaspoon without overpowering the cookie.
• A light sprinkle of flaky sea salt on top right after baking adds a little contrast and brings out the dark chocolate. It’s not required, but I highly recommended if you have it.

Step-By-Step Instructions

1. Preheat your oven to 350°F and line three baking sheets with parchment paper.
2. In a large bowl, cream the butter, brown sugar, and sugar together with an electric mixer on medium speed for 1-2 minutes, until smooth and light in color.
3. Add the egg, vanilla extract, and milk and mix just until combined.
4. In a separate bowl, whisk together the flour, baking soda, sea salt, and cinnamon.
5. Add the dry ingredients to the wet ingredients and mix until just combined. Don’t overmix here because we’re going to mix it again when we fold in the oats and chopped chocolate.
6. Using a rubber spatula or large wooden spoon, fold in the rolled oats and chopped dark chocolate until evenly distributed.
7. Using a 3 tablespoon cookie scoop, scoop the dough onto the prepared baking sheets, about 2 inches apart.
8. Bake for 10–11 minutes, rotating the pans halfway through. The tops will be set, but the cookies won’t be browned.
9. Let them cool on the pan for about 5 minutes before transferring to a wire rack to cool completely.

Recipe Tips & Notes

• The dough will be soft, but it should still hold its shape when scooped. If it feels too loose, let it sit for 10–15 minutes before baking. This will allow the oats to soak up some moisture and stiffen the dough.
• Don’t wait for browning as a doneness cue. These are done when the tops are set. Overbaking will take away that soft center.
• I like to use a baking bar and chop it up for more variation in each bite, but you can swap that out for your favorite chips if you’d prefer.
• If your cookies are spreading more than you’d like or if you’d like thicker cookies, add 1–2 tablespoons of flour next time. A little goes a long way.

Storage Recommendations

Store these cookies in an airtight container at room temperature for 3–4 days. For longer storage, baked cookies freeze well. Let them cool completely, then store in a freezer-safe bag or container for up to 2 months. When you’re ready, just let them thaw at room temperature or warm one in the microwave for 10–15 seconds.

If you want to plan ahead, freezing the dough is the best option. Scoop the dough into balls and freeze them on a baking sheet until solid, then transfer to a freezer bag. You can bake them straight from frozen at 350°F, just add a minute or two to the bake time.
