Step-by-Step
- Heat the oven to 350°F (175°C) and line baking sheets with parchment paper.
- Cut or portion the refrigerated dough into approximately 36 to 48 pieces. Roll each piece into a ball and place the balls on the prepared baking sheets, leaving about 2 inches between them.
- Bake for 10 to 12 minutes, until the edges are lightly golden and the centers still look slightly soft.
- Let the cookies cool on the baking sheets for about 5 minutes, then transfer them to a wire rack and cool completely.
- Beat the peanut butter and confectioners’ sugar together. Add the milk gradually until the filling is smooth and spreadable, then mix in the vanilla if using.
- Spread the filling over the flat side of one cooled cookie. Top with another cookie and press gently to form a sandwich.
Notes
Do not overbake, since the cookies will continue to set as they cool. Cool the cookies completely before filling so the peanut butter mixture does not soften or slide out. Store covered at room temperature for a short period or refrigerate for longer storage.
