Ingredients You’ll Need
- 100 g unsalted butter (about 7 tablespoons): For a rich and creamy base. Keep your butter at room temperature for easy mixing.
- 175 g light brown soft sugar (3/4 cup): This adds a lovely caramel flavor and helps keep the cookies moisture-rich.
- 100 g sourdough discard (about 1/2 cup): The star ingredient! It not only cuts down on waste but also adds a unique tang and depth of flavor.
- 1 medium egg: Binds the ingredients together; make sure it’s at room temperature for best results.
- 1 tsp vanilla extract: Brings out the sweetness in the cookie and complements the chocolate beautifully.
- 225 g plain flour (about 1 ¾ cups): The foundation of your cookies; all-purpose flour gives the right texture.
- 50 g cocoa powder (about 1/2 cup): Adds that rich chocolatey taste—don’t skimp!
- 1 tsp bicarbonate of soda: Helps the cookies rise and become soft in the center.
- Pinch of sea salt + extra for topping: Enhances the flavors and balances the sweetness.

How to Make Triple chocolate sourdough cookies
- Preheat the Oven: Start by preheating your oven to 200ºC/180ºC fan. While it heats, line two large baking trays with parchment paper.
- Cream the Butter and Sugar: In a bowl, beat together the 100 g unsalted butter, 175 g light brown soft sugar, and 100 g sourdough discard until the mixture is light and fluffy.
- Add Wet Ingredients: Add in the 1 medium egg and 1 tsp vanilla extract. Beat once more until combined.
- Combine Dry Ingredients: Gradually mix in the 225 g plain flour, 50 g cocoa powder, 1 tsp bicarbonate of soda, and a pinch of sea salt. Stir until just combined.
- Incorporate Chocolate Chunks: Gently fold in the 300 g chocolate chunks using a spatula or spoon, ensuring even distribution.
- Portion the Dough: Using a 5 cm cookie scoop or a heaped tablespoon, portion the dough onto the prepared trays, placing them with enough space in between for spreading.
- Bake the Cookies: Place the trays in the oven and bake for 11-13 minutes. They should be set at the edges but still soft in the center.
- Finish with Salt: As soon as they come out of the oven, sprinkle a little extra sea salt on top if desired.
- Cool Down: Allow the cookies to cool for 15-20 minutes on the tray before transferring them to a wire rack.
Storing & Reheating
These cookies can be stored at room temperature in an airtight container for about a week. For longer storage, pop them in the fridge where they’ll keep well for up to two weeks. If you want to extend their lifespan, freeze the cookies for up to 3 months in a zip-lock bag or a freezer-safe container. When you crave a chocolate treat, simply reheat them in a preheated oven at 175ºC/350ºF for 5-7 minutes. Keep in mind that the fantastic texture might slightly change after freezing, but a quick warm-up will refresh their taste!
Chef’s Helpful Tips
- Watch the baking time; overbaked cookies will firm up too much after cooling.
- Make sure your butter is softened—cold butter makes it hard to achieve that creamy mixture.
- If the dough seems too soft to scoop, let it chill in the fridge for about 30 minutes.
- Experiment with different types of chocolate chunks; a sprinkle of sea salt after baking complements dark or semi-sweet chocolate beautifully.
- These cookies can also be frozen before baking! Scoop the dough onto trays and freeze until firm, then transfer to a zip-lock for easy baking whenever the mood strikes.
There’s something incredibly satisfying about enjoying a homemade treat, especially when you’ve added a personal touch with your own sourdough discard. The triple chocolate sourdough cookies are not just about fulfilling a chocolate craving; they are about indulging in a decadent experience. I encourage you to try this recipe and feel free to experiment with flavors and textures. You might just create your own perfect version!

Recipe FAQs
Can I use whole wheat flour instead of all-purpose flour?
You can! Whole wheat flour will change the texture slightly, making it a bit denser and more rustic, but it will still taste fantastic. Consider mixing half whole wheat and half all-purpose for a lighter texture.
What can I substitute for sourdough discard?
If you’re not keen on using sourdough discard, you can replace it with an equal amount of plain yogurt or applesauce. The tanginess will be absent, but you’ll still maintain moisture in the cookies.
How should I store leftover cookies?
Keep your cookies in an airtight container at room temperature for up to a week or refrigerate them for longer freshness. Just be sure to let them come to room temperature before enjoying them again.
Can I make these cookies ahead of time?
Absolutely! You can prepare the cookie dough and refrigerate it overnight—just make sure to let it sit at room temperature for about 10-15 minutes before scooping and baking. This really helps with texture, making the cookies even better!
