While the cookies cool, beat together the softened butter and peanut butter until smooth. Add the powdered sugar and vanilla extract, mixing until fully combined.
Add the milk one tablespoon at a time, beating after each addition, until the filling reaches a smooth, spreadable consistency.
Assemble the sandwich cookies
Once the cookies are completely cool, spread a generous layer of peanut butter filling onto the flat side of one cookie. Top with another cookie, pressing gently to create a sandwich. Repeat until all cookies are assembled.
Serving & Storage Notes
These soft peanut butter Oreo-style cookies are best enjoyed at room temperature, when the filling is creamy and the cookies are tender. Store them in an airtight container at room temperature for several days or refrigerate for a slightly firmer filling. Let chilled cookies sit briefly before serving for the best texture.
