What Makes Sourdough Discard Cookies So Special?

Baking with sourdough discard might sound fancy, but trust me—it’s dead simple. Discard is just the portion of your sourdough starter that you remove when you refresh the rest. But here’s the kicker: it’s packed with flavor. The natural fermentation gives sourdough discard an ever-so-subtle tang, which works wonders in cookies.

Here’s why sourdough discard blueberry cookies deserve a spot in your recipe rotation:

• Waste reduction: Instead of tossing that leftover starter, you’re putting it to delicious use. Call it eco-friendly snacking!
• Unique flavor: The sourdough discard adds a slight tangy note that contrasts beautifully with the sweetness of the blueberries. Imagine your classic chocolate chip cookie had a fun foodie twist.
• No fancy tools required: You don’t need an expensive stand mixer or any niche baking gear—basic kitchen tools will do the trick.

Ingredients You’ll Need To Nail The Sourdough Discard Cookies

Let’s get down to brass tacks. Here’s what you’ll need to make these cookies, along with some notes on what makes each ingredient shine:

Ingredients:

• Unsalted butter – 1/2 cup (softened to room temperature; this is key for that classic cookie texture).
• Brown sugar – 3/4 cup (brings a deep, molasses-y sweetness—I prefer dark brown sugar for extra richness).
• Granulated sugar – 1/4 cup (adds a bit of crispness to balance the chewiness).
• Sourdough discard – 1/2 cup (make sure it’s unfed discard; it’s okay if it’s a little past its peak).
• All-purpose flour – 1 1/2 cups (if you have bread flour, you can sub in 1/4 cup for a chewier texture).
• Baking soda – 1/2 teaspoon (helps the cookies puff up just right).
• Kosher salt – 1/2 teaspoon (balances the sweetness and highlights the flavors).
• Lemon zest – 1 teaspoon (optional, but it amplifies the tangy blueberry vibes).
• Fresh or frozen blueberries – 1 cup (if using frozen, don’t thaw them first—they’ll bleed less).
• Vanilla extract – 1 teaspoon (because vanilla makes literally everything better).

Kitchen Tools:

• Mixing bowls (at least two; one for wet ingredients, one for dry)
• Hand mixer or sturdy whisk
• Measuring cups and spoons
• Rubber spatula (for folding in the blueberries)
• Baking sheets
• Parchment paper or silicone baking mats
• Cookie scoop or tablespoon

Instructions for Perfect Sourdough Discard Blueberry Cookies

Now comes the fun part! Set aside 15-20 minutes of hands-on time, and get ready to fill your kitchen with the smell of buttery, blueberry goodness.

1. Preheat the oven to 350°F. Line your baking sheets with parchment paper or silicone mats. Trust me, this step keeps cleanup easy and prevents sticking.
2. Cream the butter and sugars: Grab your softened butter and both sugars. Mix them until the texture turns light and fluffy. If you’re like me and sometimes forget to pull the butter out ahead of time, here’s a hack: slice it thinly and let it sit for 10-15 minutes to soften quicker!
3. Add wet ingredients: Stir in the sourdough discard and vanilla extract. Don’t panic if your discard smells extra tangy—that’s what gives these cookies their charm!
4. Combine dry ingredients: In a separate bowl, whisk together the flour, baking soda, salt, and lemon zest (if using). Little tip: zest the lemon directly over the bowl to catch all those fragrant oils.
5. Mix it all together: Slowly add the dry ingredients to the wet mixture. Stop as soon as it’s combined—overmixing can make your cookies tougher than your morning gym sesh.
6. Fold in the blueberries: Be gentle here! Fold them in with a spatula to keep them from bursting. (Okay, some may burst, but that’s part of the charm, right?)
7. Scoop and bake: Use a cookie scoop to portion dough onto your baking sheets. Leave about 2 inches between each cookie, because these babies spread.
8. Bake until golden: Pop the cookies into the oven and bake for 12-15 minutes. They should look set around the edges but still soft in the middle.
9. Cool completely (if you can wait!): Let the cookies rest on the baking sheet for a few minutes before transferring them to a wire rack. They’ll firm up as they cool—though honestly, I never make it that far without sneaking one.

Tricks & Variations

Want to make these cookies extra special? Try these ideas:

• Swap the blueberries for dried cranberries if you want a chewy bite all the way through.

• Drizzle a simple lemon glaze on top for a bakery-style finish!
