Instructions

  1. Preheat oven to 350 degrees F & line 2 baking sheets with parchment paper for even browning & to guard against burning.
  2. FOR THE COOKIE DOUGH ~ In a medium bowl, whisk together the flour, baking soda & salt.
  3. In a large bowl, & with an electric mixer at high speed, beat butter, peanut butter & both sugars until light & fluffy.
  4. Beat in eggs & vanilla, then gently fold in the flour mixture until just incorporated.
  5. Roll a rounded tablespoon of dough between your hands to make a ball, then place it on the prepared baking sheets. Repeat until cookie dough is all used up.
  6. Dip a fork in some additional granulated sugar & press each dough ball to make a crisscross pattern.
  7. Bake for 14 minutes or until lightly brown around the edges.
  8. Set the baking sheets on wire racks & cool 5 minutes before transferring cookies directly onto the wire racks to cool completely.
  9. FOR THE FILLING ~ In a medium bowl beat all filling ingredients together until creamy.
  10. Spread 1 tablespoon of the filling onto the flat side of 1 cookie & press the flat side of a 2nd cookie onto the filling, creating a cookie sandwich. Repeat until sandwich cookies are completed!
