# Steps to Follow:
01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt.
03 - In a large bowl, beat butter, granulated sugar, and brown sugar until light and fluffy, about two minutes.
04 - Beat in egg and vanilla extract until combined.
05 - Mix in half the dry ingredients, then add milk, followed by remaining dry ingredients; mix until just combined.
06 - Scoop tablespoon-sized balls onto prepared baking sheets, flatten slightly into two-inch rounds.
07 - Bake for 10 to 12 minutes until set but still soft. Allow cookies to cool completely on wire racks.
08 - Beat butter until creamy, then gradually add powdered sugar. Mix in marshmallow crème, vanilla extract, and a pinch of salt until fluffy.
09 - Spread a thick layer of frosting on a cookie, top with another cookie; repeat to form stacks of three cookies each.
10 - Spread frosting on top of stacks, sprinkle with mini marshmallows, and drizzle with melted chocolate.
11 - Press a mini candy cane into the side of each stack to resemble a mug handle, if desired.
12 - Refrigerate stacks for 10 minutes to set frosting before serving.
