Ingredients

Wet Ingredients

  • ½ cup unsalted butter, softened
  • ½ cup creamy peanut butter
  • 133 grams (about ½ cup) sourdough discard, unfed, at room temperature
  • 1 egg
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon kosher salt

Sugars

  • ½ cup granulated sugar
  • ½ cup light brown sugar, packed

Toppings

  • Hershey’s Kisses for topping
  • Sprinkles (optional)

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper to prevent sticking and facilitate even baking.
  2. Cream Sugars and Fats: In a large mixing bowl, use a hand or stand mixer to cream together the softened unsalted butter, creamy peanut butter, granulated sugar, and light brown sugar until smooth and fluffy. This process helps create a tender texture in the cookies.
  3. Add Wet Ingredients: Mix in the sourdough discard, egg, and vanilla extract until fully incorporated. The sourdough discard adds moisture and a subtle tang, enriching the flavor and texture.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and kosher salt to ensure even distribution of the leavening and seasoning.
  5. Mix Dry into Wet: Gradually add the dry ingredients to the wet mixture, mixing just until combined. Avoid overmixing to keep the cookies tender.
  6. Scoop Dough: Using a cookie scoop or tablespoon, shape the dough into balls approximately 1 to 1½ inches in diameter. Roll each ball lightly in granulated sugar to coat.
  7. Arrange on Baking Sheet: Place the sugared dough balls on the prepared baking sheets, spacing them about 2 inches apart to allow spreading.
  8. Bake and Top: Bake the cookies in the preheated oven for 10-12 minutes until edges are set but centers still appear slightly soft. Immediately upon removal from the oven, press a Hershey’s Kiss into the center of each cookie. The heat will slightly melt the chocolate, creating the signature blossom look.
  9. Cool and Decorate: Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. If desired, add sprinkles around the Kiss once slightly set for a festive touch.
  10. Serve and Enjoy: Serve these delicious sourdough discard peanut butter blossoms at room temperature and enjoy their perfect balance of nutty, sweet, and tangy flavors.

Notes

  • For best results, use room temperature sourdough discard that has not been fed recently, as this contributes the ideal tang and moisture.
  • Do not overbake: cookies should look slightly underbaked in the center when you take them out to ensure chewy texture.
  • Variations: Try chunky peanut butter for extra texture or substitute Hershey’s Kisses with your favorite chocolate candies.
  • Storage: Store in an airtight container at room temperature for up to 5 days or freeze for longer storage.
  • Sprinkles are optional but add a festive and colorful touch especially for holiday occasions.
