This one is so easy, even the kids could make it!
What Is A Sourdough Discard Cake?
Sourdough discard cake is basically a cake batter that utilises unfed sourdough starter to form part of the flour and liquid ingredients.
This particular sourdough discard cake uses 150g of discard plus 150g of additional flour. The leavening agent is baking powder which gives the cake some lift.
This cake is meant to be more like a slice in that it's baked in a rectangle tin and slightly denser in texture (thanks to the discard). It has a crunchy golden outside and a soft, sweet inside.
While this is considered a sourdough discard cake, you could of course use fed and bubbly starter to make it. It actually tastes amazing! A good excuse to feed your starter a little more and increase the amount you have in the jar!
How To Make a Sourdough Discard Cake
This cake could not be easier. You can use a scale and mixing bowl for speedy preparation. There's no need for a mixer or beaters.
It takes around 10 minutes to prepare the batter (even quicker the second time you do it!).
Here's the basic method for making a sourdough discard cake:
- Preheat the oven.
- Chop dried dates into smaller pieces.
- Add all ingredients except for melted butter into a bowl.
- Mix to combine.
- Add the melted butter and stir into a thick batter.
- Pour batter into a lined cake tin.
- Bake until golden.
- Make the drizzling glaze and drizzle over cooled cake.
What Type of Dates to Use
You will need to use dried, pitted dates for this recipe. They are different to Medjool dates.
Medjool dates are a lot more juicy and moist. They are perfect for snacking ... or filling with peanut butter!
Dried, pitted dates are sometimes referred to as "deglet noor". They can be purchased from the supermarket, generally near the raisins and nuts in the baking section.
I have used dried, pitted dates from Aldi. They are super cheap at under $2 a packet.
These are great because they have a long shelf life, making them perfect as a "pantry staple". You can use them in loads of different cakes, pastries, muffins etc.
These dates are a key ingredient in this Coffee & Maple Syrup Infused Date Sourdough Bread.
Baking Tips for Sourdough Discard Cake with Dates
While this cake is super easy to mix and bake, here are a few tips that will ensure you have success every time you bake it.
- For best results, bake this cake in a tin approximately 27.5cm x 17.5cm x 3.5cm (11" x 7" x 1.5"). This brownie pan is perfect and is the exact measurements of the pan I've used for this recipe.
- Make sure you use baking powder, not baking soda. They are actually different products.
- While this is a sourdough discard cake, it's recommended to not use old discard. The cake will be too sour. You want discard that's less than one week old for the best results.
- You can use active fed starter - in fact I often feed my starter just to make this cake! Fed, active starter will give the cake a milder flavor than using discard.
- Make sure your sourdough discard is at room temperature, along with the other ingredients. You don't want anything to be cold before mixing the cake ingredients.
There are a few different flavors you could change to make variations of this recipe. Here are a few things that I've done to make this cake different on a few occasions with great success.
- Add the zest of an orange or lemon to the cake batter.
- Use the juice of an orange for the drizzling glaze, instead of lemon.
- Use raisins instead of dates.
- Replace half the dates with chopped pecans for a crunchy twist.
- Add a shot of espresso coffee to the mixture before baking (exclude the vanilla). You don't want the coffee to be more than 20mls or it will change the texture of the cake.
How Long Does Sourdough Discard Cake Last?
This discard cake can be stored in a cake tin for up to 3 days. If you want to, you can warm it slightly after a few days to freshen it up (30 seconds in the microwave is good). It's best if you just cut it as you need it to stop the cut pieces drying out.
This cake freezes well. Wrap in parchment paper, then foil or place into a ziploc bag. Freeze for up to 2 months.
What Is Sourdough Discard
In simplest terms, sourdough discard is actually just sourdough starter that is unfed. You take out a portion of starter before you feed it with fresh flour and water.
You must take out a portion of starter before feeding for the starter to thrive.
The portion which you remove is "discarded" and is generally referred to as sourdough discard. While it can just be thrown away, you can also bake a myriad of the things with it, such as this sourdough discard cake.
Other popular things to make with sourdough discard include:
- Sourdough discard crackers
- Savory sourdough pancakes
- Sourdough discard sandwich bread
- Sourdough Grissini (breadsticks)

I'm sorry but I don't bake with cups/teaspoons because using a scale is much more accurate. You can read about why it's better to use a scale for baking here.
