- Scoop dough into muffin pans, filling two-thirds full and flattening tops.
- Bake for 8-10 minutes until edges set and a toothpick comes out mostly clean.
- Cool in pans for 5 minutes, then transfer to racks to cool completely.
- Beat unsalted butter until creamy, then gradually add powdered sugar, vanilla, salt, and milk until smooth. Mix in green food coloring.
- Pipe buttercream into the center of each cookie cup to resemble a potion.
- Decorate with sprinkles, pretzel sticks, and candy eyeballs.

Notes
