Sourdough Peanut Butter and Jelly Cookies

Hungry Yet?

Oh, sweet potato pie! If you thought Sourdough Peanut Butter and Jelly Cookies were some fancy-pants dessert only for elite bakers, think again! These babies are simple enough even your pet goldfish could whip them up (okay, maybe not the goldfish, but you catch my drift). These cookies will transport you right back to childhood—maybe even that moment when you accidentally dropped your PB&J on the floor and thought it was the end of the world. Spoiler alert: it wasn’t! Let’s get baking!

Why This Dish Slaps

Let’s just be real for a second: Sourdough Peanut Butter and Jelly Cookies are the real MVPs of the cookie world. Why? Combining the classic lunchbox combo of peanut butter and jelly with that sweet tang from sourdough starter… chef’s kiss! It’s a crunchy-on-the-outside-and-chewy-on-the-inside miracle. Each cookie is a delicious nod to your childhood while making sure your taste buds are throwing a dance party. Also, can we talk about how using sourdough starter discard means you’re fighting food waste like the superhero you are? You’ll feel like you’ve achieved a baking feat worthy of the Great British Bake Off. (Silly hat not included, but encouraged!)

Plus, making these cookies is faster than scrolling through your social media feed looking for that perfect ‘food post’ pic. Speaking of which, make sure to grab your camera for those Instagram-worthy cookie shots before devouring them. You’ll feel pretty darn proud, and your followers will thank you later!

Grab These Ingredients

Alright, here’s the lowdown on what you’ll need to make these cookies sing:

  • 2 cups (240 grams) all-purpose flour — Get that gluten going!
  • 1 teaspoon baking soda — The extra oomph for puffiness.
  • 1 teaspoon Diamond Crystal Kosher Salt — Not all salts are created equal, amirite?
  • ½ cup (113 grams, 1 stick) unsalted butter (softened) — The magic spread!
  • ½ cup (100 grams) brown sugar (packed) — Because life’s too short not to be sweet and sticky!
  • ¼ cup (50 grams) granulated sugar — A little contrast never hurt.
  • 1 large (50 grams) egg — The binding factor—like a good friend in your life.
  • ¾ cup (192 grams) smooth natural peanut butter — Smooth like your best pick-up lines.
  • ½ cup (100 grams) sourdough starter discard — Keepin’ it eco-friendly!
  • 2 teaspoons vanilla extract — A whisper of fancy.
  • ¼ cup jam of choice — Choose your own adventure, my friend!

Step-by-Step Vibes

Now, let’s get to the fun part: baking these suckers!

  1. Whisk It: In a small bowl, whisk together the flour, baking soda, and salt. Set aside for later because we’re fancy like that!

  2. Creamy Goodness: In a large mixing bowl, cream the softened butter, brown sugar, and granulated sugar until light and fluffy. It’s like giving your ingredients a little spa day.

  3. Add It All In: Beat in the egg, then add the peanut butter, sourdough discard, and vanilla extract. Mix until smooth, like butter on a hot biscuit!

  4. Stir It Up: Gradually add the dry mixture to the wet ingredients, mixing until a stiff cookie dough forms. Cover and refrigerate for at least one hour. (Pro tip: this is a great time to binge-watch that new show everyone is raving about.)

  5. Preheat Party: Preheat the oven to 350℉ (175℃) and line a baking sheet with parchment paper. We’re in business now!

  6. Cookie Time: Portion the dough and roll into balls. Press an indentation into each ball and fill with jam—you’re making little cookie cups!

  7. Bake Away: Bake for 7–9 minutes, until edges are golden brown. Let cool for about 5 minutes before transferring to a wire rack to cool completely. The patience will pay off, I promise!

Common Mistakes to Avoid

Now, before you raid your cookie stash, let’s avoid some rookie mistakes that might turn your happy cookie moment into a sad one:

  • Skipping the chill: Don’t rush! Letting that dough chill is crucial. If you skip this part, your cookies will spread out like my dietary restraint during dessert time.

  • Not using the right salt: If you skimp on seasoning, you’ll end up with cookies that taste like cardboard. Ugh, nobody wants that flavor profile.

  • Over- or underbaking: Keep an eye on those cookies! Underbaked might leave you joyfully gooey, but that joy can turn to disappointment if you’ve gone too far.

Tweak It Your Way

Feeling adventurous? Spice up the standard recipe with these fun twists:

  • Chocolate chunks: Replace half the peanut butter with chocolate chips for a double-decker treat!

  • Swap the jam: Not feeling grape? Use whatever jam you have lying around—strawberry, raspberry, heck, toss in some Nutella if you’re fancy!

  • Go crunchy: Want some texture? Toss in some chopped nuts or even crushed pretzels for a salty crunch. Because who says you can’t live life on the edge?

Curious? Here’s Answers

Got questions? I’ve got your back!

  • Can I use oil instead of butter? Sure, but why downgrade? You’ll miss that rich buttery flavor!

  • Can I prep this early? Totally, you time-saver! The dough can hang out in the fridge overnight, just like you!

  • Is using sourdough starter really necessary? Well, you won’t get that lovely tang, but if you’re desperate, you can skip it. But why would you?!

  • What’s the best jam to use? You’re the captain of this ship! Choose whatever jam tickles your pickle.

  • Can I freeze these cookies? Yes! Bake and cool them, then throw them in the freezer. Perfect for emergencies—aka cookie cravings at midnight.

They’re chewy, crispy, and packed with childhood nostalgia, just like a warm hug. So, gather your crew, share them, or indulge by yourself (no judgment here!).
