Light and Airy or Rich and Fudgy?
Before developing this recipe, I baked several batches and tested every variation I could find. Some crinkle cookies are light, cakey and airy. Others are richer and fudgier, closer to a brownie than a cake. I tested versions with melted chocolate, with creamed butter (and browned butter) instead of oil, and some that used only cocoa powder and unfermented flour (spoiler alert: they didn't work out so well...).
What I found is that oil-based dough, a small amount of sourdough discard, and a lower flour content create the perfect fudgy centre without making the cookies greasy or flat. We use a similar formula to make our Sourdough Lemon Crinkle Cookies, too!
The discard adds just enough acidity to keep the texture soft for days - one of the best things about sourdough cookie recipes - while the cocoa brings that deep, rich chocolate flavour that chocolate lovers want. This is the version that consistently produced the best results.

Ingredient Notes
Here are all the simple ingredients you'll need to make these sourdough chocolate cookies:
- Plain flour (all-purpose flour). Creates structure without making the cookies cakey.
- Unsweetened cocoa powder (natural cocoa powder). Use a good-quality cocoa for the richest chocolate flavour. Dutch-processed cocoa can also be used here.
- Baking powder and salt.
- Granulated sugar and brown sugar. The combination gives both crisp edges and chewy middles. White sugar alone makes the cookies too dry.
- Orange zest (optional). Rubbing the zest into the sugar releases fragrant oils and adds a festive aroma. We have lots of other flavour variations below if orange doesn't float your boat.
- Sourdough discard (100% hydration). Adds moisture, a touch of tang and keeps the cookies soft for longer. Avoid older discard with hooch on top - the acidic flavour will overpower the chocolate. Active sourdough starter will also work.
- Vegetable oil. Oil creates a fudgy, brownie-like crumb instead of a cakey one. You may use other neutral oils, like sunflower or avocado oil.
- Egg (large). Binds the dough and helps with that crackly top.
- Powdered sugar for rolling. Essential for the signature sugar crinkle effect.

Step-By-Step Method
1. Mix the dry ingredients. In a large bowl, whisk together the flour, cocoa powder, baking powder and salt.
2. Infuse the sugar with orange (optional but recommended). In a separate bowl, combine granulated sugar and orange zest. Rub together with your fingertips until fragrant.


3. Combine the wet ingredients. Add brown sugar, egg, sourdough discard and oil to the zesty sugar. Whisk until the mixture is smooth and the sugar starts dissolving.
4. Add the flour mixture. Tip the dry ingredients into the wet ingredients and mix until just combined. Do not overmix.



5. Chill the dough. Cover the bowl with plastic wrap and refrigerate for 4 hours, or freeze for 40-45 minutes until firm. This dough rest is essential for shaping.
6. Shape the dough balls. Preheat the oven to 180°C (350°F). Line large cookie sheets with parchment paper. Scoop heaped tablespoons of dough and roll into balls.
7. Coat in powdered sugar. Roll cookie dough balls generously in powdered sugar, ensuring a thick, even layer.


8. Bake. Arrange dough balls on a prepared baking sheet, leaving space to spread. Bake for 8-10 minutes until the cookies have cracked and look set on the edges.
9. Cool. Let the cookies firm up on the baking sheet for 10-15 minutes before moving them to a wire rack to cool completely.

Variations
Try one (or several) of these to customise your sourdough crinkles:
- Espresso powder. Add ½ teaspoon to intensify the chocolate flavour.
- Brandy-soaked cranberry centre. Press a cranberry into the centre of each cookie before rolling in sugar.
- Dried cherries. Fold 30-40g chopped dried cherries through the dough.
- Warming spices. Add ¼ teaspoon cinnamon, a pinch of nutmeg or cardamom.
- Chocolate chips. Fold through 60 g chocolate chips for extra melty pockets.
- Beetroot or matcha sugar. Mix powdered sugar with 1 teaspoon of beetroot powder or matcha for Christmas colours.

Recipe Tips
- Avoid overly acidic discard. If your discard has hooch on top, it will create an acidic flavour and a runny dough. Use discard that smells pleasant and mildly tangy.
- Expect a wet dough. The dough will be sticky before chilling. This is normal - that moisture helps create the fudgy centre.
- Chilling is essential. Without a full chill, the dough will spread too much and lose its crackle.
- Roll in sugar just before baking. If powdered sugar sits on the dough too long, it begins to dissolve and ruins the frosted look.
- Use a kitchen scale. Cocoa, flour and discard are nearly impossible to measure accurately with a measuring cup - weighing ensures perfect cookies every time.
Storage and Making Ahead
Room temperature: Store cooled cookies in an airtight container for 4-5 days.
Freeze the dough: Shape dough balls, freeze on a tray, then transfer to a freezer-safe container or zip-top bag. Allow to thaw just enough so that the powdered sugar sticks to the surface, roll and bake with 1-2 extra minutes of baking time. A great way to prepare for the holiday season ahead of time!
Freeze baked cookies: Freeze fully cooled cookies between parchment layers. Thaw at room temperature.
