These Copycat Thin Mints taste just like real Girl Scout Cookies! Crisp melt-in-your-mouth mint-chocolate wafer cookies are coated in a thin layer of a chocolate glaze-like coating. 


Units Scale

For the Wafer Cookies

  • 1/2 cup vegetable shortening (i.e. Crisco)
  • 3/4 cup sugar
  • 1/4 cup vegetable oil
  • 3 tbsp corn syrup
  • 1 tsp peppermint extract
  • 1/3 cup cocoa powder, Dutch-processed
  • 1/2 tsp baking soda
  • 6 tbsp cornstarch
  • 1/4 tsp salt
  • 1 1/2 cup flour
  • 2 tsp water

For the Chocolate Coating

  • 4 tablespoons cocoa powder, Dutch-processed
  • 4 tablespoons refined coconut oil, melted
  • 1 1/2 cups powdered sugar
  • Pinch of salt
  • 5 tablespoons hot water


  1. Make the thin mint cookie dough: in the bowl of a stand mixer (or in a large mixing bowl) cream together the shortening and sugar. Add oil, corn syrup, and mint extract, and mix until combined. Then add the cocoa powder, baking soda, cornstarch, and salt. Finally, add the flour and mix on low speed until just combined, then add the water.* Form the dough into a ball, flatten it slightly into a disk shape, and wrap it in plastic wrap. Refrigerate for at least 1 hour or overnight.


  • The dough is very crumbly, like wet sand, but holds together when pressed.
  • If the dough is sticking, coat the parchment, rolling pin, and cookie cutter with a little bit of flour. (The dough is pretty oily though so it shouldn’t stick, even without flour.)
  • Optional tips: Poke dots in the cookies with a toothpick or skewer for lookalike! And place the tray of unbaked cookies in the freezer or refrigerator for 30 minutes before baking to help hold their shape.
  • About 20 minutes after coating the cookies in chocolate (when they are partially set) use a fork to gently shift the cookies on the wire rack. This will prevent them from sticking to the rack and breaking once the chocolate is fully hardened.
