These Copycat Tagalong Girl Scout Cookies are made with a perfect buttery shortbread cookie base, a creamy peanut butter filling, and dunked in silky smooth chocolate.
Form each disk of the dough into a log about 2 inches in diameter. Fold the parchment paper over the dough and roll it gently to create a smooth, even log.
Melt the peanut butter, powdered sugar, and butter in a heat-proof bowl in 20-30 second increments, stirring in between, until smooth and it will be a bit thick (not drippy).
Dunk each cookie in the melted chocolate, coating the cookie completely. Place the cookie on a piece of parchment and repeat with the remaining cookies.
