Ingredients in Blackberry Oatmeal Cookies
- Blackberries: The star of this recipe. You will need about one cup of fresh blackberries, washed, patted dry, and quartered. Very large berries may need to be cut into sixths or eighths.
- Butter: Softened to room temperature before mixing so it creams smoothly with the sugars. Two full sticks give these cookies a rich, tender base.
- Granulated sugar: Adds sweetness and helps create lightly crisp edges on each cookie.
- Brown sugar: Fresh and soft brown sugar adds a subtle molasses flavor and contributes to the chewy texture these cookies are known for.
- Eggs: Two large eggs bind everything together and give the dough structure.
- Vanilla extract: Rounds out the flavor of the dough. The higher the quality, the better.
- All-purpose flour: The base of the dough. Cake flour also works well if that is what you have on hand.
- Baking soda: The leavening agent in these cookies. Make sure yours is not old or expired for the best results.
- Salt: Just enough to enhance and balance all of the other flavors in the dough.
- Oats: Quick oats work best, though old-fashioned oats are a great option too. For the best texture, try a 50/50 mix of both.
- White chocolate chips: A perfect pairing with the blackberries. Add as many or as few as you like, or leave them out entirely.

Tips for the Best Blackberry Oatmeal Cookies
Full instructions can be found on the recipe card below, but here are a few helpful tips.
- Do not overbake: Pull the cookies from the oven when they still look slightly underdone in the center, as they will continue to set on the pan for a few minutes after baking.
- Coat the blackberries in flour: Tossing the cut blackberries in a small amount of flour before folding them into the dough helps prevent the batter from turning purple and keeps the berries from sinking.
- Fold gently: When adding the blackberries to the dough, fold carefully and just enough to distribute them evenly. Overworking the dough at this stage can break up the berries and change the texture.
- Cream the butter and sugars well: Spending 2 to 3 extra minutes creaming the butter and sugars together makes a noticeable difference in the consistency of the finished cookie.
- Use a cookie scoop: A 1.5 tablespoon cookie scoop gives you perfectly sized, uniform cookies every single time without any guesswork.
- Line your baking sheets: Parchment paper or a silicone baking mat keeps the cookies from sticking and makes cleanup effortless.

Storage Instructions
- Store in an airtight container at room temperature for up to 3 days.
- To freeze, place cooled cookies in a single layer on a baking sheet until solid, then transfer to a freezer bag or airtight container. Freeze for up to 3 months and thaw at room temperature before serving.

FAQs
Can I use frozen blackberries? Fresh blackberries work best in this recipe, but if you use frozen, do not thaw them first. Add them straight from the freezer and coat in flour as directed to help control excess moisture.
What kind of oats are best in oatmeal cookies? Quick oats produce a slightly denser, puffier cookie, while old-fashioned oats give you a chewier result. A 50/50 mix of both is a great way to get the best of both worlds.
Can I leave out the white chocolate chips? Absolutely. The cookies are delicious without them, and you can easily swap in a different mix in like dark chocolate chips or chopped macadamia nuts if you prefer.
Why did my cookies turn purple? The natural juices in the blackberries can bleed into the dough when the berries are folded in. Coating the pieces in flour helps minimize this, and placing the cut berries in the freezer for 30 minutes before coating can reduce it even further.
How do I know when the cookies are done? The cookies are ready when the edges look set, but the centers still appear slightly underbaked, usually around 12 to 13 minutes. They will firm up as they cool on the pan.

I absolutely love the blackberries in these cookies. They give such a great colour and make a great change from more popular fruit. Also, pairing with white chocolate is genius.
Patricia @ Grab a Plate says
I’ve never thought to add blackberries to cookies, and I’m not sure why not! These are so colorful, and what great flavor they add! And the white chocolate? Yes!
Jessica says
I hope you try them Patricia!
Ashley F says
Okay these are brilliant. We love the fresh berries in these cookies! Such a great idea!
Kaylie says
Thank you Ashley!
Renee Goerger says
I was just saying how I need to bake more with blackberries, and then I found your recipe! These look amazing. I’m anxious to get them into my oven, and then into my mouth!
Kaylie says
Thank you Renee! I hope you like them as much as I do!
Jeanna Andros Baker says
Have you tried these with blueberries? Also can you use regular oats?
Cindy says
Since blackberry season just ended here, could I use frozen blackberries? These sound incredible and I can’t wait to try them!
Nellie says
You can use frozen blackberries, but frozen fruit tends to have more moisture when thawed so you may need to add a little bit more flour to compensate for that.
Nita says
How many cookies does this recipe make?
Maria says
These came out incredibly thin, nothing like the picture shows. Honestly tastes like it needs something else but I’m not sure what. I’m disappointed because I was pretty excited to make these
Sanchari says
There is something wrong with either the baking temperature listed here and/or the dough needs to be chilled or thicker. These cookies spread out super thin when made based on the instructions above. They taste pretty good but are pretty much only good as a crumble topping to ice cream.
Larissa says
How much butter? There’s no amount beside the cup measure.
Jessica says
I fixed it- it’s 1 cup!
S Wilkins says
I still have these in the oven, the baking time resulted in raw cookies. I’m increasing the time and the temperature to 350. Hopefully they will finish cooking tonight.
Nellie says
Hopefully a couple more minutes did the trick!
Judy White says
Looks like I wasn’t the only one with problems. Batter way too runny, they were completely flat. I salvaged this batch by adding more flour. Next time, 350° for 10 min, add 2 T cornstarch to stop them from spreading out, increase flour and soda.
Nellie says
Altitude, humidity, and the liquid content of the blackberries all play a part in how much flour is needed. That’s a great idea to add some cornstarch and/or extra flour if needed.
Gabby says
Super delish cookies. The batter makes enough for two entire batches of large cookies. Love the depth and complexity of the flavors. I give it 5 stars but I did read the reviews and tweaked the amount of flour, baking temp and time and a few healthier alternative ingredients. But they turned out great!
Anthony Dzioba says
We used regular rolled oats rather than quick oats. Recipe turned out great, the slight tartness from the blackberries balances it perfectly and the oats give it a slight crunch and body. Would definitely make them again.
Nellie says
Thank you so much for the feedback! I’m glad you enjoyed the cookies!
