Chewy Spiced Oatmeal Cookies with Black Sesame

These chewy spiced oatmeal cookies with black sesame are a warm, aromatic twist on the classic oatmeal cookie. Made with hearty quick oats, brown sugar, and butter, the cookies have a rich caramelized flavor that pairs beautifully with the nutty taste of black sesame and the gentle warmth of Chinese five-spice.

The dough comes together easily in one bowl with no chilling required, making this a simple cookie recipe you can prepare whenever the craving for homemade cookies hits.

Because the dough uses plenty of oats and spreads slightly during baking, the cookies develop crisp edges with a soft, chewy texture when baked on the shorter end of the bake time. Like many oatmeal cookie recipes, these cookies rely on the balance of brown sugar, butter, and oats to create that classic soft cookie texture.

Why You’ll Love These Spiced Oatmeal Cookies

Unique Flavor Twist: Chinese five-spice and black sesame add a warm, nutty depth that makes these oatmeal cookies stand out from the usual recipe.

One-Bowl Dough: The cookie dough comes together quickly without any chilling time, making this an easy baking project.

Customizable Texture: Bake them for a shorter time for softer cookies or a little longer for a firmer cookie with more caramelized flavor.

Why Chinese Five Spice and Black Sesame?

Chinese five-spice is a warm spice blend typically made with cinnamon, star anise, cloves, fennel, and pepper. These spices bring a balance of sweet, aromatic, and slightly savory notes that work surprisingly well in baked goods. These spices bring a balance of sweet, aromatic, and slightly savory notes that work surprisingly well in baked goods.

Oatmeal cookies already have a naturally hearty flavor from the oats and brown sugar, so they pairwell with warm spices. The cinnamon and clove notes in Chinese five-spice complement the caramel flavor of brown sugar in much the same way traditional oatmeal cookie spices do.

Black sesame seeds add another layer of flavor. When baked, they develop a lightly toasted, nutty taste that pairs beautifully with the warmth of the spice blend and the richness of the butter.

Together, the oats, brown sugar, Chinese five-spice, and black sesame create a cookie that still feels familiar like a classic oatmeal cookie, but with a slightly deeper, more aromatic flavor—almost like your oatmeal cookie’s fancy cousin.

Let’s Make These Spiced Oatmeal Cookies

Preheat your oven to 350°F (175°C).

In a large mixing bowl, cream together the room temperature butter, brown sugar, and white sugar until the creamed mixture becomes smooth and fluffy.

Add the egg and mix well until fully incorporated.

Stir in the water and vanilla extract.

Add the oatmeal, flour, salt, baking soda, Chinese five-spice, and cornstarch, mixing well to combine. Lastly, mix in the black sesame seeds. 

Drop the cookie dough onto a baking sheet using a teaspoon. The little mounds may seem small, but they spread during baking and become the perfect cookie size.

If you are using a non-stick baking sheet, greasing may not be necessary. Otherwise, lightly grease the pan to prevent sticking or use a parchment-lined cookie sheet.

Bake the cookies for 12–15 minutes, until the edges turn lightly golden brown. For softer cookies, remove them closer to 12 minutes when they still look slightly soft in the center.

For firmer cookies with more caramelized flavor, bake them closer to 15 minutes, keeping in mind they will become quite firm as they cool. This makes them great for dunking in a cool glass of milk.

Allow the cookies to cool for several minutes on the baking sheet, then transfer them to a wire rack to finish cooling.

Ingredients

Butter: This ingredient creates the rich flavor base for these cookies and helps produce crisp edges as they bake.

Brown Sugar: Adds moisture and a deeper caramel flavor that pairs well with warm spices.

White Sugar: A small amount of white sugar balances the brown sugar and helps the cookies spread slightly during baking.

Egg: The egg binds the dough together and contributes to the chewy texture.

Water: The added water helps hydrate the oats so they soften as the cookies bake.

Vanilla Extract: Good quality vanilla adds warmth and rounds out the flavor of the cookie dough.

Large Flake Oats: Using large flake oats gives these cookies their classic hearty texture. Oats are a great baking ingredient. If you like more yummy oat recipes be sure to try my fresh cherry oatmeal muffins.

Flour: Flour helps stabilize the cookie dough so the cookies hold their shape while baking.

Salt: This balances the sweetness and enhances the flavor of the spices.

Baking Soda: Helps the cookies rise slightly and contributes to their soft interior.

Chinese Five-Spice: This spice blend brings warm, aromatic flavor that works beautifully with oatmeal and brown sugar. I used McCormick’s Chinese Spice Blend for the cookies. 

Cornstarch: A small amount of cornstarch helps keep the cookies tender and soft in the center while preventing them from spreading too thin.

Black Sesame Seeds: Black sesame seeds add a subtle nutty flavor and a unique visual contrast in the cookies. McCormick’s also has lovely fresh seeds.

Substitutions and Add-Ins To The Oatmeal Cookies

Butter: Margarine can be used instead of butter if needed. It works well in oatmeal cookies, though the finished cookies will have a slightly different flavor.

Brown Sugar: Dark brown sugar can be used for a deeper molasses flavor, but brown sugar should remain part of the recipe for the best chewy texture.

White Sugar: Remains.

Egg: If needed, one flax egg can be used, but the texture will be a little softer and less structured.

Water: Remains. The water helps hydrate the large flake oats and contributes to the softer texture of the cookies.

Vanilla Extract: Almond extract or maple extract could be used for a different flavor, but vanilla works best with the warm spice blend.

Oats: Large flake oats work best, but quick oats can be used if needed. The cookies will simply have a softer texture. Instant oats are not recommended for this recipe because they absorb moisture differently and can make the cookies too soft.

Flour Options: All-purpose flour works best for this recipe.

Salt: Remains.

Baking Soda: Remains. This helps the cookies rise slightly and affects the final texture.

Black Sesame Seeds: If black sesame seeds are unavailable, white sesame seeds can be substituted for a similar nutty flavor. The black sesame seeds give nice visual contrast and look especially striking in the cookies.

Chinese Five-Spice: If you want a milder flavor, reduce the amount slightly or substitute a mix of cinnamon with a pinch of cloves or nutmeg.

Optional Add-Ins: These cookies also work well with chopped walnuts, raisins, or even a handful of chocolate chips for oatmeal chocolate chip cookies!

Expert Tips, Serving, and Storing Suggestions

Tip #1: Watch the Bake Time Carefully: These cookies change texture depending on how long they bake. Remove them closer to 12 minutes for softer cookies.

Tip #2: Let Them Cool Completely: The cookies will be very soft when they first come out of the oven. Letting them cool on the pan allows them to firm up without breaking.

Tip #3: Leave Space Between Cookies: Because the dough spreads slightly, leaving space between scoops helps the cookies bake evenly.

These cookies pair beautifully with tea, coffee, or warm milk. The spices and sesame flavor also make them a nice addition to a dessert tray or afternoon snack.

Store the cookies in an airtight container at room temperature for up to 4 days to keep them soft.

For longer storage, freeze the baked cookies for up to 3 months and thaw at room temperature before serving.
