Chocolate Stuffed Sourdough Peanut Butter Cookies

Soft, rich, and indulgent — these sourdough peanut butter cookies are already a favorite, but the addition of a gooey chocolate ganache center takes them completely over the top. A buttery, slightly tangy dough wraps around creamy peanut butter and melts into a soft chocolatey bite with every taste.

Equipment

  • Kitchen Scale
  • Stand Mixer
  • Measuring spoons
  • Heatproof bowl (for ganache)
  • Small saucepan (for heating cream)
  • Spatula (for stirring ganache and dough)
  • Plastic wrap or lid (to cover and chill ganache)
  • Whisk (for dry ingredients)
  • 3 Tablespoon cookie scoop
  • Baking sheet
  • Parchment Paper
  • Large round cookie cutter (at least 6 inches wide) or wide glass for shaping (optional)
  • Cooling rack

Ingredients
  

For the cookies

  • 170 g unsalted butter ¾ cup, softened
  • 150 g brown sugar ¾ cup
  • 100 g white sugar ½ cup
  • 2 teaspoon vanilla extract
  • 1 large egg
  • 1 large egg yolk
  • 100 g sourdough discard ⅓ cup
  • 250 g creamy peanut butter 1 cup
  • 270 g all-purpose flour 2 ¼ cups
  • 1 teaspoon baking soda
  • ½ teaspoon fine sea salt
  • 67 g sugar ⅓ cup, for rolling the dough balls
  • ¼ teaspoon instant espresso powder optional

for the ganache

  • 4 oz semi-sweet or bittersweet chocolate chips about ¾ cup
  • 80 ml heavy cream ⅓ cup
  • 14 g unsalted butter 1 tbsp

Instructions
 

  • Make the ganache: Heat the cream until steaming (do not boil). Pour over the chocolate chips and butter in a heatproof bowl. Let sit for 2–3 minutes, then stir until smooth. Cover and refrigerate for 1–2 hours, or until firm enough to scoop. Scoop into 1-teaspoon portions and keep chilled while you prepare the cookie dough. Preheat the oven to 350°F (175°C).
  • Cream the butter & sugars: In a large bowl, beat the butter, brown sugar, and white sugar until light and fluffy (2–3 minutes).
  • Add wet ingredients: Mix in the vanilla, egg, and egg yolk until smooth. Stir in the sourdough discard and peanut butter until fully combined.
  • Add dry ingredients: In a separate bowl, whisk together the flour, baking soda, and salt. Mix into the wet ingredients just until no streaks of flour remain. No need to chill.
  • Assemble the cookies: Scoop 3-tablespoon portions of dough (about 60g each). Flatten slightly, place a chilled (1-teaspoon) ganache scoop in the center, and wrap the dough around to seal. Roll each dough ball in granulated sugar.
  • Bake: Arrange cookies on a lined baking sheet and gently press them down with a fork to help them flatten while baking. They don't need to be totally flat, just not round as these don't spread much. Bake for 10–12 minutes, until edges are set but centers still look soft.
  • Cool: Scoot the hot cookies around with a large round cookie cutter to make them perfectly round if preferred. Let cookies rest on the tray for 5 minutes, then transfer to a wire rack to cool completely.

Notes

  1. NOTE: I bake by weight for accuracy. Cup measurements are approximate and may vary depending on how you scoop.
  2. I use a 3-tablespoon cookie scoop to portion these, which makes 60g balls of cookie dough. You can also use a 2-tablespoon cookie scoop, which makes 40g dough balls, and this would yield around 30-35 cookies.
