Why You’ll Love This Recipe
These cookies are incredibly simple to make and require only a few pantry staples. They come together quickly with minimal hands-on time, making them perfect for both beginner and experienced bakers.
Another reason to love this recipe is the clever use of sourdough discard. Instead of wasting leftover starter, you can turn it into a flavorful batch of cookies with a delicate tang that complements the buttery texture.
The flavor combination is also outstanding. The bright orange zest lightens the rich shortbread, while the dark chocolate coating adds a smooth and slightly bitter contrast that balances the sweetness.
Finally, these cookies are easy to customize. You can shape them into rectangles, squares, or circles, and even experiment with different types of chocolate or citrus zest.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the Cookies
¾ cup unsalted butter, softened
⅔ cup granulated sugar
133 grams sourdough discard (about ½ cup), unfed and at room temperature
1 tablespoon orange zest
1 teaspoon vanilla extract
2 ¼ cups all-purpose flour
½ teaspoon kosher salt
For the Topping
3–4 ounces dark chocolate, chopped or chocolate chips
2 tablespoons granulated sugar
½ teaspoon orange zest
Directions
In a large mixing bowl or the bowl of a stand mixer fitted with a paddle attachment, cream the softened butter and granulated sugar together for about 2–3 minutes until light and fluffy.
Add the sourdough discard, orange zest, and vanilla extract. Mix until everything is fully combined, scraping down the sides of the bowl if needed.
Add the all-purpose flour and kosher salt. Mix on low speed until the ingredients are incorporated, then increase the speed slightly and continue mixing until a soft dough forms.
Transfer the dough to a clean work surface and divide it into two equal portions.
Shape each portion into a log or rectangle approximately 2 inches wide and 1 inch thick. Wrap each piece tightly in plastic wrap and refrigerate for at least 1 hour to firm up.
Preheat the oven to 350°F (180°C). Line two baking sheets with parchment paper.
Remove the chilled dough from the refrigerator and unwrap it. Use a sharp knife to slice the dough into ¼-inch thick cookies.
Place the cookies on the prepared baking sheets, leaving about 2 inches of space between each cookie to allow for slight spreading.
Bake one tray at a time for 12–14 minutes, or until the bottoms of the cookies begin to turn lightly golden while the tops remain pale.
Transfer the baked cookies to a wire rack and allow them to cool completely.
In a small bowl, mix the granulated sugar with the orange zest for the topping.
Melt the dark chocolate gently in a small saucepan or double boiler over low heat, stirring until smooth.
Dip one end of each cooled cookie into the melted chocolate. Place the cookies back on the wire rack or parchment paper.
While the chocolate is still warm, sprinkle the orange sugar mixture over the chocolate-coated portion. Let the cookies sit until the chocolate has fully set.
Servings and timing
Servings: 32 cookies
Prep time: 20 minutes
Chill time: 1 hour
Cook time: 12–14 minutes
Total time: about 1 hour 35 minutes
Variations
You can easily adapt these cookies to create different flavor profiles.
For a lemon version, replace the orange zest with fresh lemon zest. This gives the cookies a brighter and slightly tangier citrus flavor.
Another variation is to change the chocolate coating. Milk chocolate creates a sweeter finish, while white chocolate produces a creamy and delicate flavor.
You can also add texture by mixing finely chopped nuts such as almonds or pistachios into the dough before chilling.
For a more festive appearance, drizzle extra melted chocolate across the finished cookies or sprinkle them with finely chopped candied citrus peel.
Storage/Reheating
These cookies store very well, making them perfect for baking ahead.
At room temperature, place the fully cooled cookies in an airtight container and store them for up to two weeks. Keep them in a cool, dry place to prevent the chocolate from melting.
For longer storage, you can freeze the cookies. Once the chocolate coating has hardened, place them in a freezer-safe container or bag and freeze for up to two months. Thaw the cookies at room temperature before serving.
Reheating is not necessary, as these cookies are meant to be enjoyed at room temperature.
FAQs
What is sourdough discard?
Sourdough discard is the portion of sourdough starter that is removed before feeding it with fresh flour and water. Instead of throwing it away, it can be used in recipes like cookies, pancakes, and quick breads.
Can I use active sourdough starter instead of discard?
Yes, you can substitute the discard with the same amount of active sourdough starter. However, the cookies may spread slightly more during baking.
Why do I need to chill the dough?
Chilling the dough firms up the butter and helps the cookies hold their shape during baking. It also improves the overall texture.
Can I make these cookies without a stand mixer?
Yes. You can use a hand mixer or even mix the dough by hand with a sturdy spoon.
Can I skip the chocolate coating?
Yes, the cookies taste wonderful even without the chocolate. You can simply sprinkle the tops with orange sugar for a lighter finish.
Can I use a different citrus flavor?
Absolutely. Lemon, lime, or even blood orange zest works beautifully in this recipe.
How do I keep the cookies from spreading too much?
Make sure the dough is thoroughly chilled and leave enough space between the cookies on the baking sheet.
Can I make the dough ahead of time?
Yes. The dough can be prepared and refrigerated for up to two days before slicing and baking.
Can I freeze the cookie dough?
Yes. Wrap the shaped dough logs tightly and freeze them for up to two months. Slice and bake directly from frozen, adding a few extra minutes to the baking time.
What kind of chocolate works best?
Dark chocolate provides the best balance with the buttery cookies, but milk or white chocolate can also be used depending on your taste preference.
