The simple ingredients you need
You only need a handful of pantry staples to whip up a batch of these loaded cookies.
- Sourdough Discard
- You can use active starter or unfed discard. It adds moisture and a very subtle tang that cuts through the sweetness.
- Unsalted Butter
- Make sure your butter is at room temperature so it creams perfectly with the sugar.
- Brown Sugar
- Packed brown sugar provides moisture and a rich, caramel-like flavor essential for chewy cookies.
- Egg & Egg Yolk
- The extra yolk adds richness and keeps the cookies tender.
- Vanilla Extract
- A splash of pure vanilla enhances all the other flavors.
- All-Purpose Flour
- The base structure of our cookies. Measure by spooning and leveling for accuracy.
- Old-Fashioned Rolled Oats
- Provides that classic, hearty cowboy cookie texture. Avoid quick oats if possible.
- Cornstarch
- The secret ingredient for extra soft and thick cookies.
- Baking Powder & Baking Soda
- A combination of both leavening agents ensures the right amount of spread and rise.
- Ground Cinnamon & Salt
- Cinnamon adds warmth, while salt balances the sweetness.
- Chocolate Chips
- Semi-sweet is standard, but dark chocolate chips work wonderfully too.
- Pecans & Shredded Coconut
- Chopped pecans add crunch, and sweetened shredded coconut adds a delightful chew.
How to make this sourdough cowboy cookies
- Preheat the oven: Preheat to 350°F (175°C) and line baking sheets with parchment paper.
- Whisk the dry ingredients: In a medium bowl, whisk together the flour, oats, cornstarch, baking powder, baking soda, cinnamon, and salt.
- Cream the butter and sugar: In a large bowl or stand mixer, beat the room temperature butter and brown sugar until light and fluffy.
- Add wet ingredients: Mix in the egg, extra egg yolk, and vanilla extract until well combined, scraping down the sides as needed.
- Mix in the discard: Gently fold the sourdough discard into the wet mixture.
- Combine wet and dry: Gradually add the dry ingredient mixture to the wet ingredients, mixing just until no flour streaks remain.
- Fold in the mix-ins: Use a spatula to stir in the chocolate chips, chopped pecans, and shredded coconut.
- Chill the dough: Cover the bowl and refrigerate the dough for at least 30 minutes to prevent the cookies from spreading too much.
- Scoop and bake: Drop rounded tablespoons of dough onto the prepared baking sheets. Bake for 10-12 minutes, or until the edges are golden brown but the centers are still soft.
- Cool: Let the cookies rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Serving Ideas
These cookies are incredibly satisfying on their own, but here are a few ways to elevate them:

Prep and storage advice
To keep your sourdough cowboy cookies tasting fresh and chewy, store them in an airtight container at room temperature for up to 5 days. Placing a slice of bread in the container will help keep them soft!
You can also freeze the baked cookies for up to 3 months. Alternatively, freeze the unbaked cookie dough balls on a baking sheet, then transfer them to a freezer bag. Bake straight from frozen, just adding an extra minute or two to the baking time.

FAQs
Can I use active sourdough starter instead of discard?
Yes! You can use either unfed discard or bubbly, active starter. Since this recipe relies on baking powder and soda for leavening, the state of the starter mainly contributes flavor and moisture.
Why do my cookies spread too much?
Spreading usually happens if the butter was too warm or the dough wasn’t chilled long enough. Make sure to chill the dough for at least 30 minutes before baking.
Do I have to use coconut?
Not at all. If you aren’t a fan of coconut, simply leave it out, or replace it with an equal amount of extra oats or nuts.
