Sourdough discard monster cookies
Updated: Mar 8
Here another great recipe using sourdough discards: monster cookies!
It's not totally my recipe but I adapted it from here and then I added some peanut M&M's to make them more colourful and delicious :)
I think this is a very smart way to use all your sourdough discards, the process is a bit long but I think the result is great!
Check out the recipe below if you want to make them too!!
230g cold butter
220g dark brown sugar
100g granulated sugar
2 teaspoons vanilla extract
1 teaspoon baking soda
1 teaspoon salt
1 large egg
125 g sourdough starter discard*
280g all-purpose flour
170g rolled oats
200g add-ons* (chocolate, M&M's, nuts..)
In a bowl cream together cold butter (cut into chunks), granulated sugar, brown sugar, vanilla extract and salt with the electric mixer or a stand mixer until you get a creamy batter.
Add the egg and mix to incorporate.
Scrape down the sides of the bowl and add the sourdough starter discard.
Add gradually the flour and mix until it is absorbed. Then scrape down the sides and the bottom of the bowl and add rolled oats. Mix until combined.
Finally leave the mixer and add all your favourite add-ons (I added chocolate chips, chocolate chunks and crushed peanut M&M's); mix with a rubber spatula until incorporated.
At this point the dough will be very sticky so place it on a large piece of plastic wrap on your counter and wrap it around it.
Place in the fridge and store for 2 days (this helps the oats absorb the excess liquid from the discard so the dough will be less sticky and easier to handle).
Preheat oven to 350°F (180°C) and cover a baking tray with parchment paper.
Divide the dough into 1cm thick disks or balls (they should weight about 50 grams each) and place it well-spaced in the prepared tray.
Bake for about 15 minutes or until lightly browned around the edges.
The center of the cookie will be a bit under-baked so as soon as you remove them from the oven you can push a couple of pieces of M&M's on top of the disks to make them look prettier and more colourful :)
Let them cool on the tray for about 5 minutes before moving them on a serving plate.
My sourdough starter discard was a few days old and cold from the fridge.
You can use any add-ons you want: miniatures M&M's will be definitely prettier than the ones I used.
You can freeze the dough for 2 months or so.
I used less add-ons compared to the original recipe because I thought 200g was enough but feel free to add more!
If you make it let me know! :)
