Blackberry Cream Oatmeal Sandwich Cookies Ingredients
• Delight in these simple yet flavorful components!
For the Cookies
- Coconut Sugar – Adds a rich depth of flavor; substitute with brown sugar for a similar taste.
- Gluten-Free Flour – Ensures structure in the cookies; a 1:1 baking blend works best.
- Vegan Butter or Shortening – Creates a rich texture; shortening gives a stiffer cream, while butter may need more powdered sugar if too soft.
- Gluten-Free Quick Cooking Oats – Provides chewiness and acts as a binder; make sure they’re certified gluten-free.
For the Blackberry Cream Filling
- Oregon Blackberries (Canned or Frozen) – The star ingredient that gives flavor and vibrant color; if using frozen, strain any excess liquid before mixing.
- Powdered Sugar – Sweetens the cream; adjust to your taste for the perfect blackberry cream consistency.

Step‑by‑Step Instructions for Blackberry Cream Oatmeal Sandwich Cookies
Step 1: Prep the Blackberries
In a medium saucepan over medium heat, add Oregon blackberries and cook for about 5–7 minutes until they begin to break down and thicken. Stir occasionally to prevent sticking. Once reduced, remove from heat and blend the mixture with powdered sugar until smooth. This creates a luscious filling for your Blackberry Cream Oatmeal Sandwich Cookies.
Step 2: Make the Cookie Dough
In a large mixing bowl, combine coconut sugar and vegan butter. Using a hand mixer, cream them together until smooth and light in color, about 2–3 minutes. Gradually add gluten-free flour, continuing to mix until fully combined, then fold in the gluten-free quick cooking oats. The dough should be slightly sticky yet manageable.
Step 3: Shape and Bake the Cookies
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Scoop tablespoon-sized portions of the cookie dough and roll them into balls, then gently flatten each one before placing them on the prepared baking sheet, leaving space in between. Bake for 10–15 minutes until the edges are golden and the centers are set but soft.
Step 4: Cool the Cookies
Once baked, remove the cookies from the oven and allow them to cool on the baking sheet for about 5 minutes. Carefully transfer the cookies to a wire rack to cool completely. It’s essential to let them cool fully, as this will ensure that they hold their shape when you add the creamy blackberry filling.
Step 5: Assemble the Sandwich Cookies
Once the cookies have cooled, take one cookie and spread a generous layer of the blackberry cream filling on the flat side. Top it with another cookie, pressing gently to create a sandwich. Repeat this process until all the cookies are assembled with the delightful blackberry cream.
Step 6: Serve and Savor
These delicious Blackberry Cream Oatmeal Sandwich Cookies are best served fresh. Their vibrant color and scrumptious taste will surely be a hit at any gathering. For an extra special touch, pair them with a glass of almond milk or enjoy them with your favorite cup of tea!

How to Store and Freeze Blackberry Cream Oatmeal Sandwich Cookies
Room Temperature: Keep uneaten cookies in an airtight container at room temperature for up to 2 days to maintain their delightful softness.
Fridge: For slightly longer storage, refrigerate the sandwich cookies in an airtight container for up to a week. Just be aware that they may become a tad firmer.
Freezer: Unfilled cookies can be frozen for up to 2 months. Place them in a single layer on a baking sheet to freeze, then transfer to a freezer bag.
Reheating: If you enjoy warm cookies, reheat the filled cookies gently in the microwave for about 15 seconds or until just warmed through. Enjoy the deliciousness of your Blackberry Cream Oatmeal Sandwich Cookies!
Helpful Tricks for Blackberry Cream Oatmeal Sandwich Cookies
-
Monitor Baking Time: Keep a close eye on the cookies while they bake; they can go from perfect to overdone quickly. Aim for a lightly golden edge for the best texture.
-
Adjust Cream Thickness: If your blackberry cream is too runny, add more powdered sugar to achieve your desired consistency for the filling.
-
Storage Savvy: Store your cookies in an airtight container at room temperature for up to two days, but the Blackberry Cream Oatmeal Sandwich Cookies taste best when enjoyed fresh.
-
Cookie Dough Consistency: Make sure your dough is slightly sticky but not overly wet; this will help the cookies hold their shape while baking.

Make Ahead Options
These Blackberry Cream Oatmeal Sandwich Cookies are a fantastic option for busy home cooks looking to streamline their meal planning! You can prepare the cookie dough up to 24 hours in advance by wrapping it tightly in plastic wrap and refrigerating. Additionally, the blackberry cream filling can be made ahead and stored in an airtight container in the fridge for up to 3 days; just give it a quick stir before using to revive its luscious texture. When you’re ready to serve, bake the cookies from the chilled dough directly, then allow them to cool before assembling with the cream filling. This way, you’ll enjoy the vibrant flavors while saving precious time during your hectic week!

Blackberry Cream Oatmeal Sandwich Cookies Recipe FAQs
How do I choose ripe blackberries for the filling?
Absolutely! Look for plump, dark berries that are slightly soft to the touch. They should have a rich color without any dark spots or signs of mold. If you’re using frozen blackberries, I recommend thawing them completely and straining any excess liquid before cooking down.
What’s the best way to store leftover cookies?
Very! Store uneaten Blackberry Cream Oatmeal Sandwich Cookies in an airtight container at room temperature for up to 2 days. If you prefer them a bit firmer, refrigerate them for up to 1 week. Just remember, they may lose some of their lovely softness when chilled!
Can I freeze these cookies?
Yes, indeed! To freeze unfilled cookies, first let them cool completely. Then, lay them in a single layer on a baking sheet to freeze for about 1-2 hours. Once frozen, transfer them to a freezer-safe bag or container, where they can last for up to 2 months. When you’re ready, just thaw them at room temperature before filling with creamy goodness!
What if my cookie dough is too sticky?
No problem! If your dough is overly sticky, try adding a tablespoon of gluten-free flour at a time until it reaches a more manageable consistency. It’s essential for shaping those delightful cookies to have a dough that can hold its form during baking.
Are these cookies suitable for people with nut allergies?
Absolutely! These cookies are made without nuts, making them a great choice for those with nut allergies. Just be sure to use gluten-free oats and flour blends that are certified nut-free as well!
How long will these cookies stay fresh?
I often make these cookies and find that they taste best fresh, ideally within 2 days. If stored properly in an airtight container, they’ll still be enjoyable for a few days longer, but be mindful of humidity as it can affect texture. For the best results, enjoy them soon after making!
