Baking time: 1 hour
Total Time: 1 hour
Servings: 4
Calories: 398kcal


  • 90 g Chocolate good quality semi sweet
  • 50 g Unsalted butter
  • 1 Egg yolk
  • 50 g Granulated sugar
  • 50 g Brown sugar
  • 120 g Sourdough discard
  • 20 g Cocoa powder Unsweetened Dutch processed
  • 80 g Bread flour high protein
  • Pinch of salt

US customary cup measurement is an indicative figure only. Measure the ingredients with a digital scale by weight (gram). Baking is art but also science which requires precision and accuracy.


  • Melt butter and chocolate in a bowl over simmering water then set aside
  • In another bowl beat together egg, granulated sugar, brown sugar and the sourdough discard
  • Pour the melted butter and chocolate mixture into the egg mixture and mix until well combined
  • Sift in flour, salt and cocoa powder and fold the mixture together
  • Divide the dough into 9 equal balls using either an ice cream scoop or spoon. Do not soften the surface, in fact try to keep it as rough as possible for a nice, crackly surface
  • Place them onto a large baking tray lined with parchment paper. Leave space in between them. Let them rest in the freezer for 10 minutes
  • Pre-heat oven to 180 C / 356 F
  • Remove the baking tray from the freezer and bake the cookies for 15 minutes


TIP: After 10-12 minutes remove the tray from the oven and tap it a few times onto the kitchen counter. This will help to achieve the brownie like crackly crust on the top of the cookies.

Such a good way to use up sourdough starter. These cookies are so delicious and fun to make. They all disappeared off the plate in minutes so will definitely be making again!

Oh thank you for your feedback! I love this recipe too, soo easy and such a great way to use up sourdough starter instead of throwing out:)

We have loved making these as a way to use my husband’s sourdough discard during the pandemic. Though his starter has lower hydration, they are still so delicious. He recently split his starter into two so we can try it with 100% hydration. I’m hoping to make them today!

Looking for a good brownie recipe – could you put this in a 9×9 pan and make brownies instead? You have good reviews so will try as a cookie regardless. Thanks!

While I did not have the exact choc type at home, I decided not to waste time & money to buy another bag of choc. It was bitter choc so I added a bit more brown sugar. Also, mine were a mouthful glob unlike Katalin’s. But they still taste good. Now, time to spend money on a nice pint of vanilla ice cream to pair with them.

These came out wonderfully! When I asked my 4-year-old if we should bake cookies or brownies this weekend, she answered “brownie cookies.” I thought to myself, well, those don’t exist. But when I found your recipe, she was excited. Quite a simple recipe & a great family baking project. My cookie sheet doesn’t fit in my freezer, so I covered it & placed it outside, which is literally freezing right now. Not sure what I’ll do when the temperatures are warmer because my family all loves these & we will definitely make them again! Thank you so much for the recipe.

That’s a wonderful way for me to use my discard.
I substituted coconut oil for butter and reduced 5G each on both brown sugar and granulated sugar.
Taste really really good , also found taste even better the day after 😝😝
Thank you for the recipe❤️
