If you love cookies that are rich, fudgy, and intensely chocolatey, these double chocolate oat cookies deliver everything you want in a chocolate dessert. With the depth of cocoa powder, the chew of old-fashioned oats, and the decadence of melted chocolate chunks, these cookies strike the perfect balance between satisfying and indulgent.
Pinterest users love chocolate recipes, and double chocolate oat cookies consistently rank among top-performing pins in the cookies category. They look rustic, decadent, and cozy—all qualities that make dessert lovers stop scrolling and save the recipe. These cookies stay soft for days, freeze beautifully, and offer a bakery-style texture that makes them feel special without requiring complicated steps.
Let’s dive into what makes this cookie stand out and how to make them perfectly every time.
What Makes Double Chocolate Oat Cookies So Good?
These cookies are the ideal combination of three textures:
Chewy from the oats
The oats add structure and bite without overpowering the chocolate.
Soft and fudgy in the center
Cocoa powder and brown sugar create a soft brownie-like center.
Crisp around the edges
The butter and granulated sugar help the edges bake into a delicate crisp.
This cookie has the richness of a double chocolate brownie but the heartiness of an oatmeal cookie. The oats lighten the texture so the cookies don’t feel too dense, while the chocolate keeps everything decadent and satisfying.
They’re the kind of cookie that feels cozy in winter, indulgent any time of year, and extremely photogenic in recipe blogs and on Pinterest.

Eggs
Bind ingredients and support a soft interior.
Vanilla extract

Chewy Double Chocolate Oat Cookies
Equipment
- small mixing bowl
- microwave-safe bowl
- stand mixer or hand mixer
- spatula
- cookie scoop (1.5 tablespoon)
- baking sheet lined with parchment paper
- wire rack for cooling
Ingredients
- 3 cups oat flour (certified gluten free)
- 1 teaspoon kosher salt
- 1/4 teaspoon baking soda
- 1 cup unsalted butter (dairy-free optional)
- 3/4 cup cocoa powder
- 2/3 cup light brown sugar (packed)
- 2/3 cup granulated sugar
- 2 large eggs (room temperature)
- 1 tablespoon vanilla extract
- 1 1/2 cups semi-sweet chocolate chips
Instructions
- In a small bowl, whisk together the oat flour, salt, and baking soda. Set aside.
- Melt the butter in short microwave bursts until just melted, then whisk in cocoa powder until smooth and combined.
- In a stand mixer or with a hand mixer, cream the melted butter-cocoa mixture with the brown and granulated sugars until light and fluffy.
- Add eggs one at a time, then mix in vanilla extract until just combined.
- Add the dry ingredients to the butter mixture, mixing on low until just combined. Fold in the chocolate chips by hand.
- Using a 1½-tablespoon scoop, portion dough onto a baking sheet so the balls touch slightly. Freeze for at least 30 minutes.
- Preheat oven to 375°F. Arrange chilled dough balls on a parchment-lined baking sheet, spacing 2 inches apart.
- Bake for 12–14 minutes, rotating halfway through. Allow cookies to cool on pan for 10 minutes before transferring to a rack.
Notes
Storage: Store in an airtight container up to 4 days or freeze cookie dough balls up to 1 month.
Step-by-Step Instructions
- Preheat your oven and line baking sheets with parchment paper.
- Cream the butter and both sugars until fluffy.
- Add the eggs and vanilla, mixing until fully combined.
- In a separate bowl, whisk together flour, cocoa powder, baking soda, and salt.
- Add dry ingredients to the wet mixture and mix until just combined.
- Fold in the oats and chocolate chips or chunks.
- Scoop cookie dough onto baking sheets, giving each cookie room to spread.
- Bake until edges look set but centers appear soft.
- Cool on the baking sheet to allow the cookies to finish setting.
The key is to avoid overbaking. Like brownies or rich chocolate cookies, these taste best when the center stays slightly soft.
Texture Tips for Perfect Double Chocolate Oat Cookies
Here’s how to ensure your cookies come out bakery-quality every time:
Use rolled oats, not quick oats
Quick oats absorb too much moisture and make cookies dry.
Cream butter and sugar correctly
This step creates the soft and chewy structure.
Do not overmix after adding flour
Overmixing leads to tough cookies.
Use quality cocoa powder
High-quality cocoa creates deeper flavor and richer color.
Add extra chocolate on top
Press a few chips or chunks onto each dough ball for great presentation.
Slightly underbake
The cookies will continue to set as they cool and stay chewy for days.
Chill the dough (optional)
A 20–30 minute chill thickens cookies and deepens flavor, ideal for photography.
These techniques help create cookies that look professional and taste even better.
Why Chocolate and Oats Work So Well Together
While oatmeal cookies are usually associated with cinnamon or raisins, the pairing of oats with deep cocoa creates a completely different flavor experience. The oats add body and chew that complement the richness of chocolate instead of competing with it.
Oats also help the cookies stay soft for several days, making them ideal for holiday prep, gifting, or baking ahead for parties. This combination gives readers a cookie that’s indulgent yet grounded, satisfying without being overly sweet.
Optional Add-Ins and Variations
These variations help you turn one recipe into multiple Pinterest-friendly posts:
Triple Chocolate Oat Cookies
Add white chocolate and dark chocolate for layers of flavor.
Salted Double Chocolate Oat Cookies
Sprinkle flaky sea salt on top for gourmet appeal.
Nutty Chocolate Oat Cookies
Add chopped walnuts, pecans, or almonds.
Double Chocolate Cherry Oat Cookies
Fold in dried cherries for a brownie-meets-black-forest flavor.
Mocha Oat Cookies
Add espresso powder and chocolate chunks for a richer profile.
Double Chocolate Mint Oat Cookies
Add a few drops of peppermint extract for a holiday twist.
White Chocolate Double Oat Cookies
Add white chocolate chips for contrast and sweetness.
These variations offer a lot of value for recipe bloggers who want more internal links and Pinterest boards built around chocolate desserts.
