These Sourdough Breakfast Cookies come from the lockdown trend of sourdough starters and baking banana bread. It does not seem you have experienced lockdown unless you have baked a loaf of banana bread or have a sourdough starter on the go.

The slow down of work commitments was a good time for myself to attempt a sourdough starter again so I jumped on the bandwagon. Getting a starter going and fed is easy for the first week. The novelty wears off come the second week and keeping it alive and “happy” becomes really tricky when you don’t bake bread that often. There is also a lot of daily discard – the amount of starter you need to remove each day when feeding. Luckily there are many recipe ideas that do not involve baking a loaf of bread and these Sourdough Breakfast Cookies from Tara Jensen looked so good that I wanted to try them.

I tweaked the recipe as I did not have whole wheat flour, wheat germ or maple syrup so just replaced it with cake flour and dark demerara sugar. I added some dark chocolate chips and a teaspoon of instant coffee powder (from when I made these amazing Dalgona Coffee Cheesecakes).

The cookies are delicious and “substantial”, with loads of texture. The nuttiness of the toasted oats and seeds come through, it has a slight sour tang from the sourdough discard and I love the slightly bitter chocolate flavour in the mix.
