The Magic of Matcha: Flavor and Benefits in Every Bite
Matcha, a finely ground powder made from green tea leaves, brings more than just its vibrant green color to these Matcha White Chocolate Sourdough Cookies. Its earthy, slightly bitter flavor pairs perfectly with the sweetness of white chocolate, creating a balanced and unique taste. When you use ceremonial or high-quality culinary grade matcha, you’ll get the best flavor and color, elevating your cookies to something truly special.
Beyond flavor, matcha offers a range of health benefits. Packed with antioxidants, vitamins, and minerals, it provides a natural energy boost while also promoting relaxation thanks to the amino acid L-theanine. Incorporating matcha into your baking not only enhances the flavor but also adds a wholesome touch to your cookies. If you’re a matcha lover, these cookies are a delicious way to enjoy both the taste and benefits of this vibrant ingredient.

Matcha White Chocolate Sourdough Cookie Success Tips
- Use active sourdough starter: Ensure your starter is active and bubbly before adding it to the dough for the best texture and flavor.
- Let the dough rest: After fermenting for 8 hours, allow the dough to come to room temperature before shaping for better consistency.
- Don’t overmix: Mix the dry ingredients into the wet ingredients just until combined to avoid tough cookies.
- White chocolate tip: Gently fold the white chocolate into the dough to ensure even distribution and melty pockets in each cookie.

How to Make Matcha White Chocolate Sourdough Cookies
- Cream the Butter and Sugar:
In a stand mixer fitted with the paddle attachment (or by hand), beat the softened butter and granulated sugar on medium-high speed until light and fluffy, about 3 minutes. - Add Wet Ingredients:
Add the sourdough starter, egg, and vanilla extract and beat until well combined. - Incorporate Dry Ingredients:
Slowly beat in the flour, matcha powder, milk powder, baking powder, baking soda, and salt until just combined. Then fold in the chopped white chocolate. - Ferment the Dough:
Cover the dough tightly and let it ferment at room temperature for 8+ hours. You can refrigerate the dough after fermentation if you’re not ready to bake right away. - Preheat and Shape:
When ready to bake, preheat the oven to 350°F (177°C). Roll the dough into 12-14 cookies, each weighing about 60g. Place the cookie dough balls onto parchment-lined baking sheets and press the middles down slightly. - Bake the Cookies:
Bake for 8-12 minutes, or until the edges are lightly golden. Remove from the oven and let the cookies cool completely on the baking sheet before serving.
Health Benefits of Sourdough Cookies✨
Sourdough cookies go through natural fermentation with sourdough starter, which contains wild yeast and lactic acid bacteria (LAB). This ancient process breaks down gluten, reduces anti-nutrients, and improves digestibility. Sourdough foods are rich in fiber, prebiotics, vitamins, and antioxidants, making them a wholesome and satisfying treat for your gut health.

I am a vegan and I want to make these cookies. Can I substitute flaxseed egg for the eggs?
Hi! Thanks for reaching out! Try adding a “flax egg” (1 tbsp flaxseed meal + 2btsp water) or you can use any other egg alternative liquid.
I want to try this recipe, but i am new to sourdough. I have a starter, and have baked bread already (succesfully) but i was wondering if the sourdough starter shouldbe active or not?
oops i was too fast ddelet my comment hhahah
Hey! Can I freeze this dough and bake later! Thank you!!!
Absolute perfection! I switched up the sugar and did half brown, half white and put about 15g less sugar than called for. Also added 2 teaspoons of milk powder too and were fantastic.
Absolutely loved this recipe! It was so good a big hit with my girlfriends ❤️
