Sourdough Discard Brownies

Sharing is caring!

Sourdough Discard Brownies are rich, fudgy, and oh-so delicious! These are made with sourdough discard from the sourdough starter you have going on!

They are very chocolatey thanks to the 2 types of chocolate and 2 types of sugar making this one of the best brownie dishes you will ever make.

How to Make Sourdough Discard Brownies

One of the things that I think makes this brownie recipe so different from the others is that the butter gets browned before adding it to the batter. There is just something about browned butter that makes any dish taste better.

The chocolate chips get melted by the butter and then that gets added to all the other ingredients. Bake in a pan until you get your desired doneness.

Do not use a toothpick to test these brownies. Once the edges look set and there is no jiggle left, these brownies are done! I prefer a fudgier brownie so I always like to bake mine for less time than more time.

For this recipe, you will use a 9×9 baking pan. I like to line mine with parchment paper. It keeps the brownies from sticking and you can lift the whole pan of them out at once.

Store your sourdough discard brownies in an airtight container at room temperature or in the fridge for up to 4 days.

These brownies can also be frozen. Just wrap each individual brownie and then place them into an airtight freezer container. They'll keep in the freezer for up to 3 months. 

When you're ready to enjoy, simply thaw the brownies on the counter at room temperature for about an hour.
