Ingredients You Will Need
Before you start mixing your dough you need to gather all your ingredients on the counter. Make sure your butter and your sourdough discard are at room temperature so they blend together smoothly. Here is exactly what you will need to make these amazing cookies.
-
One half cup of unsalted butter softened to room temperature
-
One cup of creamy peanut butter though you can use crunchy if you like texture
-
One half cup of active or inactive sourdough discard
-
One half cup of white granulated sugar
-
One half cup of packed brown sugar for extra moisture and caramel flavor
-
One large egg at room temperature
-
One teaspoon of pure vanilla extract
-
One cup of all purpose flour
-
One half teaspoon of baking soda
-
One half teaspoon of baking powder
-
One half teaspoon of fine sea salt for the dough mix
-
Two tablespoons of flaky sea salt reserved for sprinkling on top before baking
Step by Step Method
Follow these simple steps carefully to ensure your cookies turn out perfectly soft and delicious every single time.
First you need to prepare your workspace and your oven so everything runs smoothly. Preheat your kitchen oven to three hundred fifty degrees Fahrenheit. While the oven is heating up take two large baking sheets and line them with parchment paper. This lining prevents the cookies from sticking to the bottom and makes cleaning up later very quick and easy.
Next take a large mixing bowl to combine your wet ingredients. Place your softened unsalted butter white granulated sugar and packed brown sugar into the bowl. Use a hand mixer or a sturdy wooden spoon to beat these ingredients together for about three minutes. You want the mixture to look light fluffy and pale yellow in color.
Now it is time to add the star ingredients to the creamed sugar mixture. Scoop in your creamy peanut butter and your sourdough discard. Add the large egg and the pure vanilla extract into the same bowl. Stir everything together vigorously until the batter becomes completely smooth and uniform with no streaks of egg or starter visible.
In a separate medium bowl you will mix your dry ingredients together. Pour in your all purpose flour baking soda baking powder and fine sea salt. Use a whisk to stir these dry ingredients for a few seconds. Whisking helps break up any clumps in the flour and ensures the baking soda is spread evenly throughout the mixture.
Slowly pour your dry flour mixture into the large bowl with your wet peanut butter mixture. Use a silicone spatula to gently fold the ingredients together. Stir just until the flour disappears into the dough. You must be careful not to overmix at this stage or your cookies might turn out tough instead of soft.
Cover the mixing bowl with a piece of plastic wrap or a clean kitchen towel. Place the bowl into your refrigerator for at least thirty minutes. Chilling the dough is an important step because it solidifies the butter which keeps the cookies from spreading too flat while they bake in the oven.
Once the dough is chilled use a cookie scoop or a large spoon to measure out equal portions. Roll the dough between your clean hands to form smooth round balls that are about the size of a golf ball. Place these dough balls onto your prepared baking sheets leaving two inches of space between each one.
Take a regular kitchen fork and gently press it down into the top of each dough ball to flatten it slightly. Lift the fork rotate it ninety degrees and press down again to create a beautiful crisscross pattern on the surface. This classic pattern helps the thick peanut butter dough bake evenly all the way through.
Just before you put the trays into the oven take your flaky sea salt and sprinkle a tiny pinch onto the top of each cookie. The large salt flakes will stick to the dough and create a wonderful crunchy contrast to the sweet peanut butter flavor.
Slide the baking sheets into your preheated oven and bake for eleven to thirteen minutes. You will know they are done when the edges look golden brown and set but the very center still looks a little soft. Do not overbake them or they will lose their wonderful chewy texture.
Remove the baking sheets from the oven and let the cookies rest on the hot tray for five minutes. They will be very delicate right after baking so this resting time allows them to firm up. After five minutes use a spatula to transfer them to a wire cooling rack to cool completely.
Why This Recipe Is Special
This specific recipe stands out from traditional cookie recipes because it utilizes the power of fermentation. The sourdough discard adds a gentle tang that balances the heavy sweetness of the sugars and the richness of the peanut butter. This creates a multidimensional flavor profile that keeps your taste buds excited with every bite. You get the classic comfort of a childhood snack combined with the sophisticated depth of an artisan bakery product.
From a practical standpoint this recipe is a fantastic way to practice zero waste cooking in your home. Instead of washing your extra starter down the kitchen sink you are transforming it into a high value treat. It saves money and makes you feel good about using every bit of food in your pantry. The sourdough process also helps break down phytic acid in the flour which can make the finished cookies easier on sensitive stomachs.
Additionally peanut butter provides a good amount of plant based protein and healthy fats which gives these cookies more nutritional substance than standard sugar cookies. They satisfy your sweet tooth while keeping you feeling full for a longer period of time. The addition of flaky sea salt on top stimulates your taste buds and enhances the perception of sweetness without needing to add extra cups of refined sugar.
Extra Tips for Better Taste
If you want to make these cookies even more spectacular you can try adding a handful of semi sweet chocolate chips to the dough. The combination of chocolate peanut butter and sourdough is absolutely incredible and tastes like a gourmet candy bar. You can also swap the chocolate chips for chopped dark chocolate chunks if you prefer a deeper more bitter contrast to the sweet dough.
Another great trick is to use a high quality natural peanut butter that contains only peanuts and salt. If you use natural peanut butter make sure to stir it very well before measuring so the natural oils are distributed evenly. For an extra crunch you can replace half of the creamy peanut butter with crunchy peanut butter to add real peanut bits throughout the cookie.
You can also experiment with the chilling time to develop deeper flavors. Leaving the cookie dough in the refrigerator overnight allows the flour to fully hydrate and lets the sourdough flavor mature even more. When you bake the dough the next day you will notice a richer caramel color and an even softer interior texture.

Baking sourdough discard salted peanut butter cookies is a joyful experience that fills your kitchen with warmth and incredible aromas. It is the perfect project for anyone looking to try something new with their baking routine while reducing kitchen waste.
