The Science of Quinoa in Baking & Moisture Retention
Incorporating cooked quinoa into cookies is a clever way to add nutrition without compromising texture. The key lies in quinoa’s composition: it’s a complete protein and contains starches that help bind the dough and retain moisture.
When cooked and cooled, the quinoa grains are soft and slightly sticky, which helps create a chewy, dense crumb rather than a cakey one. The quinoa’s natural moisture also means the cookies stay soft for days.
Using a combination of oats and all-purpose flour provides structure while maintaining a hearty, whole-grain feel. The high ratio of brown sugar adds moisture and caramel notes, enhancing the quinoa’s nuttiness.
Ingredients

For the Cookies:
- 1 cup (120g) all-purpose flour (or gluten-free 1:1 blend)
- 1 cup (90g) old-fashioned rolled oats
- ½ teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- ½ cup (1 stick / 113g) unsalted butter, softened
- ¾ cup (150g) packed light brown sugar
- ¼ cup (50g) granulated sugar
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1 ½ cups (about 225g) cooked and cooled quinoa*
- 1 cup (170g) dark chocolate chips or chunks
Note: Cook ½ cup (90g) dry quinoa according to package directions to yield about 1 ½ cups cooked. Spread it on a plate to cool completely before using.
Instructions
1. Combine Dry Ingredients: In a medium bowl, whisk together the flour, oats, baking soda, baking powder, and salt. Set aside.
2. Cream Butter & Sugars: In a large bowl, beat the softened butter, brown sugar, and granulated sugar together with an electric mixer until light and fluffy, about 2-3 minutes.

3. Add Wet Ingredients: Beat in the egg and vanilla extract until fully combined. The mixture may look slightly curdled if the egg is cold—this is okay.
4. Incorporate Quinoa & Dry Mix: Using a spatula, stir in the cooled, cooked quinoa until evenly distributed. Gradually add the flour-oat mixture, stirring just until no dry streaks remain. Gently fold in the chocolate chips.

5. Chill the Dough (Optional but Recommended): For thicker, chewier cookies, cover the bowl and refrigerate the dough for at least 30 minutes. This prevents excessive spreading.
6. Scoop & Bake: Preheat oven to 350°F (175°C). Line baking sheets with parchment paper. Scoop 2-tablespoon portions of dough, roll into balls, and place 2 inches apart on the sheets. Slightly flatten the tops with your palm. Bake for 12-14 minutes, until the edges are golden brown but the centers still look soft.

7. Cool & Serve: Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. They will firm up as they cool. Enjoy warm or at room temperature.
Pro-Tips for Perfect Quinoa Cookies
- Cool the Quinoa Thoroughly: Warm quinoa will melt the butter and cause the cookies to spread too much. Spread it on a plate to cool quickly.
- Don’t Overmix: Once the flour is added, mix just until combined to avoid tough cookies.
- Chill for Thickness: Chilling the dough solidifies the butter, resulting in a thicker, chewier cookie. If you’re in a rush, you can bake immediately, but they will spread more.
- Use a Scoop for Evenness: A cookie scoop ensures uniform size and even baking.
- Underbake Slightly: Take them out when the centers look soft for the ultimate chewy texture.
- Storage: Store cooled cookies in an airtight container at room temperature for up to 4 days. They also freeze beautifully for up to 2 months.
