Ingredients
 

Main Ingredients

  • 0.5 cup unsalted butter, softened
  • 0.75 cup creamy peanut butter
  • 0.5 cup granulated sugar
  • 0.5 cup light brown sugar, packed
  • 1.8 oz egg, lightly beaten about 1 large egg without shell
  • 1 tsp vanilla extract
  • 1.5 cup all-purpose flour
  • 1 tsp baking soda
  • 0.25 tsp fine salt
  • 1 cup semisweet chocolate chips for ganache filling
  • 0.33 cup heavy cream for ganache filling
  • 0.5 tsp vanilla extract for ganache filling

Instructions

Preparation Steps

  • Heat oven to 350°F. Line two baking sheets with parchment.
  • Cream butter, peanut butter, granulated sugar, and brown sugar until fluffy, 2–3 minutes.
  • Beat in the egg and vanilla until smooth and glossy.
  • Whisk flour, baking soda, and salt in a bowl. Add to the mixer and blend just until a soft dough forms.
  • Scoop 1-inch portions and roll into balls. Arrange 2 inches apart on the baking sheets.
  • Flatten each ball gently with a fork in a crosshatch for even thickness.
  • Bake 9–11 minutes until edges set and centers look soft. Cool 5 minutes, then transfer to a rack.
  • Warm the cream until steaming. Pour over chocolate chips in a bowl and let sit 2 minutes.
  • Stir until silky. Mix in vanilla. Let thicken at room temperature until spreadable, about 15 minutes.
  • Pair cookies by size. Spread or pipe a spoonful of ganache on one and cap with another. Press gently.

Notes

Swap fillings: use 1 cup chocolate-hazelnut spread for a faster sandwich. Or add a pinch of flaky salt on top before baking for a sweet-salty finish. Store sandwiches airtight at room temperature for 2 days or refrigerate up to 1 week; bring to room temp before serving.
