Ingredients You’ll Need
You won’t need much to make these gooey, fudgy cookies! Here’s what you’ll need:
- ½ cup sourdough discard: This is a great way to use up your discard while adding that slight tang and moisture to the cookies.
- 1 cup dark chocolate chips: For that rich, chocolatey goodness! You could also use semi-sweet if that’s what you have.
- ¼ cup unsalted butter: A must for that tender texture. Just remember to use real butter for the best taste!
- ¾ cup granulated sugar: Sweetness is key in this dessert. You could also play around with brown sugar for a bit more caramel flavor!
- 1 large egg: Helps bind everything together.
- 1 teaspoon vanilla extract: Because vanilla makes everything better!
- ⅓ cup unsweetened cocoa powder: This is where that deep chocolate flavor comes from!
- ½ cup all-purpose flour: Essential for the structure of the cookies.
- ½ teaspoon baking powder: To help them rise just a little.
- ¼ teaspoon salt: A couple pinches of salt here will balance out the flavors.
- ½ cup chocolate chunks: Because who can resist even more chocolate?
Let’s Get Cooking!
Ready to whip these cookies up? Here’s how to do it step-by-step:
Preheat and Prepare
First things first, preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. This will ensure the cookies don’t stick and makes for easy cleanup!
Melt the Chocolate and Butter
Now, grab a microwave-safe bowl and place your chocolate chips and butter inside. Microwave them in 20-30 second increments, stirring frequently, until the mixture is nice and smooth. This should take just a minute or so. The aroma of melting chocolate will be divine!
Mix in the Sugar
Once you’ve got that delicious chocolate mixture ready, add in the granulated sugar. You’ll want to whisk until everything is combined and glossy. This is when the magic starts to happen!
Whisk in the Egg and Vanilla
Next, mix in the egg and vanilla extract. Keep whisking until the batter becomes thick and smooth, almost like satin! At this point, if you could bottle up that smell, I would sell it!
Add the Sourdough Discard
Time to add your sourdough discard! This is the secret ingredient that makes these cookies extra special. Mix until it’s fully incorporated. You won’t taste the sourdough, but it adds so much depth!
Fold in the Dry Ingredients
Now, add the cocoa powder, all-purpose flour, baking powder, and salt to the chocolatey base. Gently fold everything together until a thick batter forms. Make sure not to overmix!
Chocolate Chunks, Please!
Fold in the chocolate chunks evenly throughout the dough. Can you imagine how gooey they’ll be once baked? I can already see them melting in my mind!
Optional Rest
Here’s a little insider tip: let the dough rest for about 15 minutes. This gives it time to thicken up a bit, so you get those perfectly shaped cookies once you scoop them out.
Scoop and Bake
Scoop tablespoon-sized portions of dough onto your prepared baking sheet, making sure to leave some space between each cookie (they’ll spread a little). Pop them into the oven for 10-12 minutes until the tops look shiny and crackled, and the edges are just set, this will ensure a fudgy center.
Cool Down
Once they’re ready, remove the cookies from the oven and allow them to cool on the baking sheet for about 10 minutes. Then transfer them to a cooling rack to cool completely (if you can wait that long!)
