Winter Edition — A Year of Sourdough Chocolate Chip Cookies

Indulgent sourdough double chocolate chip cookies made with freshly milled soft wheat flour, orange and sea-salt. Classic cookies with crispy edges, soft centers and rich dark chocolate. Bake right away or cold-ferment for up to 48 hours.

Hi, my name is Sarah, and I’m addicted to all things chocolate and orange!

I remember the first time I ate a piece of Apelsinkrokant chocolate as a little girl. It didn’t only taste delicious, it made sense. I’m sure everyone has that one flavor they’re magically drawn to. This is mine.

I’ve shared sourdough chocolate chip cookies on this blog before. They’ve been the long-fermented kind, with surprisingly complex flavors, and a texture that leans modern bakery-style, with crispy edges and cakey centers.

But whenever my thoughts turn to double chocolate chip cookies, all I can think of are those old-school, flat, crispy-edged, chewy cookies. The kind I fell in love with as a teenager when a coffee shop opened right across my school, serving only American-style treats.

It took quite a few attempts to get these right. but I finally cracked the code to flat, crispy, fresh-milled double chocolate chip cookies. And I’m here to share.

Why You’ll Love These Fresh-Milled Cookies

Let’s be honest.

To some, fresh-milled flour is the perfect food. Others struggle with it, because they have a hard time letting go of familiar tastes and textures. But with these sourdough chocolate cookies, you can actually get both: the familiar, deeply indulgent taste and texture of a classic chocolate chip cookie, but also that satisfying feeling of having eaten food.

So instead of trying to convince you that I magically fermented a double chocolate cookie into health food, let me just tell you this: These cookies are incredible.

They’re the old-school kind, typically found in a tall glass jar in your favorite coffee shop. The ones that spread thin, crisp up around the edges, stay soft in the middle, and leave a confident grease stain.

With dark Dutch-process cocoa powder, bright orange zest and just the right balance of sea salt, they carry the flavor of my forever favorite chocolate bar.

And using up a scoop of sourdough discard while you’re at it?

Worth it. Every time.

Tools You May Need

Digital Kitchen Scales or Measuring Cups Your kitchen, your call. Weighing ingredients delivers more reliable results than volume measurements though.

Unbleached Baking Paper

#50 Cookie Scoop
Holding 1.5 tablespoons of batter, a #50 scoop is my preferred tool for making sensibly sized double chocolate chip sourdough cookies.

Cooling Rack
It takes a while for all the melted chocolate to cool down completely, before you can store the cookies. Cooling racks make life a lot easier here.

Important Ingredients & Substitutions

Soft Wheat Flour Fresh-milled soft wheat flour is the best choice for baking cookies. It has less gluten-forming proteins, so you don’t run the risk of over mixing the batter and ending up with tough cookies.
If you’re not milling flour at home (yet), whole wheat pastry flour is the closest match in the U.S. In Europe, any whole wheat flour can be used in place of fresh-milled soft wheat.

Corn Starch
To achieve the classic spread, we need a little corn starch (corn flour in the UK) to weaken the structure of the batter and make the cookies collapse in on themselves during baking. It also makes the edges crispier and the texture softer than regular whole wheat cookies.

Dutch Processed Cocoa Powder
Dutch processed is dark and rich. Don’t swap natural cocoa powder, as it will change the acidity of the batter.

Light Brown Sugar (American-Style)
American light brown sugar is “wet” compared to the dry, granulated brown sugar in Germany. Though they often behave similar enough in baking, you really need American-style brown sugar for classic chocolate chip cookies.
Tip: You can make your own light brown sugar by stirring 1 tablespoon (20g) of molasses or sugar beet syrup into 1 cup of granulated white sugar.

Orange
We need both the zest and a little juice, so choose organic if possible.

Egg Yolk
One yolk is enough to act as a binder, without creating fluffy domes instead of flat, crispy cookies.

Dark Chocolate Chunks
Use dark chocolate chips, chunks, or a chopped chocolate bar (I like 70% cacao). If you love a chunky texture, use a bake stable chocolate.

Fine Sea Salt
Weighing salt may seem a little excessive, but depending on coarseness and brand, one teaspoon can taste a lot saltier than the next. Saltiness per weight is a lot more reliable.

Flaky Sea Salt (optional)
If you like a little extra salty crunch, you can sprinkle the cookies with flaky sea salt before baking.

Step 04

Add the dry ingredients into wet ingredients. Stir until halfway combined, then add the dark chocolate chunks and fold in until flour and chocolate are well incorporated. The batter should be smooth and glossy.
Cover and rest the batter for at least 20–30 minutes at room temperature (or up to 48 hours in the fridge).

Step 05

Preheat the oven to 185°C/365°F and line a baking sheet with parchment paper.
Scoop about 1½ tablespoon mounds of batter and leave at least 2cm/5 inches space in between.
Sprinkle with flaky sea salt (optional), and bake on the lower middle rack for 8-12 minutes.

Step 06

Cookies are done when the edges feel set and firm to the touch, but the middles are still a little soft and puffy. Rest them on the hot baking sheet for 3-5 minutes to finish setting, then transfer to a cooling rack and leave to cool completely.

my best tips for baking indulgent fresh-milled cookies that don’t taste like whole wheat

  • Why Brown Sugar Matters
    A mix of granulated sugar and molasses, American brown sugar is a functional ingredient in chocolate chip cookies. That little bit of molasses helps to keep the centers soft. If you can’t buy it, you can easily make your own American-style brown sugar at home.
  • Rest, Chill & Fermentation Times
    Don’t skip resting the batter before baking, so the flour has time to hydrate and create the right texture. You can also rest the batter for up to 48 hours in the fridge to reap the benefits of sourdough fermentation.
  • Control the Spread
    For crispy but chewy chocolate chip cookies, the batter needs to be “weak”, so it collapses in the oven. With fresh-milled grains, protein content and other factors can vary by growing season and area.
    If you find your cookies spreading too much or too little, you can adjust the texture by swapping small amounts (5g at a time) of flour and corn starch: the more corn starch, the flatter the cookies.
  • Bake to Taste
    If you love soft centers, bake cookies only until the edges feel set and the middle is still puffy and soft (but not raw). For crispier cookies, bake until the edges feel firm to the touch and the centers look baked.

Variations

  • Classic Sourdough Double Chocolate Chip Cookies
    Swap vanilla extract for the orange juice and omit the orange zest.
  • Milk Chocolate Sourdough Cookies
    For a more kid-friendly cookie, skip the flaky sea salt and swap chopped milk chocolate for the dark chocolate chunks.
  • Mexican Double Chocolate Chip Cookies
    Replace orange juice with vanilla extract, omit the orange zest, and add a pinch of chili powder to the wet ingredients instead.

How to Store & Freeze Sourdough Double Chocolate Chip Cookies

  • Storing Baked Cookies: Store cookies in a cookie tin at room temperature for up to 1 week (often longer). Make sure the chocolate has set fully before storing.
  • Freezing Baked Cookies: Place fully cooled cookies in a freezer-safe bag or airtight container and remove as much air as possible to reduce freezer burn and ice crystal formation. Freeze for up to 1-2 months. Remove from the bag and let sit at room temperature overnight to thaw.
  • Freezing Cookie Dough: Portion out the dough, place on a baking sheet (or in a freezer safe container) without touching, and freeze until solid. Transfer to a freezer-safe bag, removing excess air. You can bake cookies directly from frozen. No need to thaw, just add 2–3 minutes to your usual baking time and enjoy fresh double chocolate chip cookies in under 30 minutes.

Recipe FAQs

Yes! If you’re not milling flour at home, you can replace fresh-milled soft wheat flour with whole wheat pastry flour in the U.S., or any whole wheat flour in Europe.

Yes, you can chill and ferment the batter in the fridge for up to 48 hours. Fermentation increases flavor and reduces sweetness a little, without loosing that classic chocolate cookie charm.

Fresh-milled flour strength can vary depending on your batch of grain. If you want your cookies to spread more, replace 5g of fresh-milled flour with 5g of cornstarch. For cookies that spread less, either use a little more fresh-milled flour in place of the cornstarch, or try one whole egg per batch.

Of course. For a double batch of chocolate sourdough cookies, you can use one whole egg instead of two egg yolks.


I’d love to hear how they turned out!

    I have to work a bit more on the timing when baking these cookies because they were either extremely soft or crispy🙄. But they have a deep chocolate flavor and the orange really came through. I will definitely make these again and probably also the version with vanilla.
