How To Make Blackberry Oatmeal Cookies

Ready to get baking? Let’s make these cookies!

Prep Time: First, preheat your oven to 325°F (160°C). Line a baking sheet with parchment paper. This will make cleanup much easier. Seriously, do it, you’ll be glad you did!

Cream It: In a large bowl, beat the softened butter, brown sugar, and your granulated sugar until it’s smooth and creamy. The mix will get nice and fluffy!

Add Wet: Beat in the eggs one at a time. Then, mix in the vanilla extract. Combine until everything is well blended.

Combine Dry: In a separate bowl, mix 1 ¼ cups of the flour, the baking soda, and the salt. Add this mix to the butter mixture. Combine them until just mixed, but don’t overmix.

Mix Ins: Add the quick oats and white chocolate chips. Mix gently until they’re spread evenly.

Berry Prep: In a small bowl, put the remaining 2 tablespoons of flour. Gently coat the blackberries with flour until they’re all covered. This prevents purple streaks! (If you want, freeze berries for 30 minutes for extra color protection, but it works well even without this!)

Berry Fold-In: Gently fold the floured blackberries into the cookie dough, just until they’re spread evenly through the mix.

Drop It: Use a cookie scoop or tablespoon to place dough on the baking sheet, making sure to leave a little space in between cookies.

Bake: Put them in the oven for 12-13 minutes. The edges should look light brown when ready.

Cool Time: Let the cookies cool on the baking sheet for about 5-7 minutes before carefully putting them on a wire rack to cool entirely. Cooling them on the pan gives them the perfect texture, so don’t skip this part!

Tips for the BEST Blackberry Oatmeal Cookies

Okay, listen up cookie masters! These are my best tricks for taking these cookies from GOOD to AMAZING!

Use soft butter: Making sure the butter is soft and pliable is VERY IMPORTANT in creating a consistent and amazing cookie batter, helping mix everything well. Don’t make them melted though.

Don’t Overbake: This is very crucial. If you over bake you’ll end up with HARD dry cookies and we all KNOW nobody wants them. Bake the cookies til they look almost set, like almost but not quite then just take em’ out.

Use quality berries: Use quality ripe but also firm blackberries. You’ll thank me for this later on. If you end up having too soft berries the will turn everything into a soft mash. Try to find good blackberries to create good looking cookies.

Chilling: I always add about 20-30 mins in the fridge to all the cookies before they get baked. It prevents your cookies from spreading too much making the soft inside perfect and soft. It also improves taste.

Variations : Feel free to swap or add on this recipie with different ingredients! Like maybe chopped nuts? Or different type of berries? Or a teaspoon of almond extract to make em’ POP! The possibilities are ENDLESS! Get wild.

Why are my Blackberry Oatmeal Cookies bitter?

A bitter taste in your oatmeal cookies can often come from using old baking soda or too much baking soda. Make sure your baking soda is fresh. If it’s been sitting in your pantry for a while, it might be time to replace it. Too much of it can also give your cookies a not-so-great taste, so it is important to measure accurately. Also, old oats can sometimes contribute to a bitter taste, so using fresh oats is a good idea. Make sure all your ingredients are as fresh as possible for the best result.

Why are my cookies falling apart?

If your oatmeal cookies are crumbling, it’s likely because there isn’t enough binding in the dough or the ingredients were not measured correctly. This can happen if you don’t use enough butter or eggs or use a substitute. Make sure your butter is soft but not melted, and that you are using the correct amount of each ingredient. Also, sometimes overbaking can lead to crumbly cookies, so keep an eye on the baking time. Another cause could be not letting them cool down completely before moving them off of the baking sheet, which is also a key step to keep the cookies from falling apart.

FAQs

Can I use frozen blackberries?

Yep, you CAN use frozen blackberries! But do NOT thaw them first. Adding them directly into the batter will help prevent the batter from turning purple from all the extra berry juice! Also, adding an extra minute or two to your cooking time can also work fine.

Can I use instant oats?

For this specific recipe I do not recomend using instant oats because you’ll need to keep them full, since the texture from rolled oats really work BEST in this scenario. If you replace rolled with instant the cookies will be softer, maybe like too soft.

How long do these cookies stay fresh?

If you keep these stored in a airtight container, you will see that you can keep these cookies good for around 3-4 days. But I’m betting you and your family will make these babies dissapear before that.

Can I use a different berry?

You can always swap the blackberries with other type of berries! But these taste SOOO good together! If you still are aiming to change them it can be blueberries or even some rasberries. Strawberries also work. Try mixing different berries and see if they work.

My cookies spread too much, what went wrong?

This might occur when the oven wasn’t preheated when there was too much melted butter in your mix, or simply just maybe not chilling enough! Try making your butter soft not melted. and also try chilling them for the 20 to 30 minutes. You should get perfect results!
