In a saucepan, combine sugar, butter, milk, cocoa powder, and salt. Bring to a boil over medium heat, stirring constantly.
Once boiling, remove from heat and stir in oats, vanilla extract, and peppermint extract until well combined. Drop spoonfuls onto wax paper and let cool.
For the mint layer, mix powdered sugar, softened butter, heavy cream, peppermint extract, and food coloring until smooth. Spread over cooled cookies.
For the chocolate drizzle, melt chocolate chips and coconut oil together. Drizzle over mint layer once set.
