Sourdough Cookies Recipe

Is your sourdough starter in overdrive? Don’t chuck it out, use it up with this master recipe for sourdough cookies.

These cookies are:

  • So easy to throw together;
  • Use up excess sourdough starter;
  • Are a perfect project for little bakers;
  • A master recipe you can tweak with different flavours;
  • Completely egg-free;
  • Oh, and they’re delicious!

If you’re a sourdough baker you’ll know that every now and again you end up with more starter than you can handle. Which is where sourdough “discard” recipes come in. We sure love us some sourdough pasta, crumpets or crackers to use up extra starter. But nothing beats these sourdough cookies for maximum ease and brownie points!

This recipe is also completely egg-free and you could even make it vegan by substituting your favourite dairy-free butter alternative for the butter (although they may end up more crispy and less rich without the butter fat).

These cookies come out thick and chewy in the middle with crispy edges and a crinkly rustic top which we consider cookie perfection. If you like them crispy all the way through, you can also just add a few minutes on to the baking time.

Sourdough Cookies Flavourings

Choose your own flavours

You can tweak this basic recipe super easily to make use of the ingredients in your pantry or include your favourite flavours. We’ve included two of our favourite flavour combos below.

Macadamia and wattleseed cookies are a real bushfood treat. And we also have our go-to double chocolate combo for when you need to eat your feelings. But really, any nut, dried fruit or spice could work – the pantry is your oyster! Go forth and experiment.

Get kids baking

This recipe uses the “drop cookie” technique, which means it’s perfect for little fingers. The cookies require no fiddly shaping. You just drop tablespoons of the mix on baking sheets and go.

But best of all, they need no rolling or pre-chilling. So you can pop them straight in the oven once the kids are licking the beaters. And you’ll be eating cookies before you know it. Tall glasses of milk are not optional.

Baking cookies is our go-to winter school holiday boredom buster. And you get bonus afternoon tea!
