Instructions

Cookie Preparation: Preheat your oven to 350°F (175°C). In a saucepan over low heat, melt together the softened butter, brown sugar, water, and chocolate chips, stirring continuously until the mixture is smooth and fully melted. Allow this chocolate mixture to cool slightly to prevent cooking the eggs in the next step.
Mix Wet Ingredients: In a separate mixing bowl, whisk the eggs and vanilla extract until combined, then gradually incorporate them into the cooled chocolate mixture until well blended.
Combine Dry Ingredients: In another bowl, whisk together the flour, baking soda, and salt. Slowly add this dry ingredient mix into the chocolate-egg mixture, stirring gently until just combined to avoid overmixing.
Form Cookies: Using a rounded teaspoon, scoop the cookie dough onto ungreased baking sheets, spacing each about 2 inches apart to allow for spreading during baking.
Bake Cookies: Place the baking sheets in the preheated oven and bake for 10-12 minutes, or until the cookies are set but remain soft. Once baked, allow the cookies to cool completely on wire racks before assembling.
Prepare Mint Filling: In a clean bowl, beat together the confectioners’ sugar, softened butter, milk, peppermint extract, and optional green food coloring until the filling is smooth and creamy, with no lumps.
Assemble Sandwich Cookies: Spread a generous amount of the prepared mint filling onto the flat side of half the cooled cookies. Top each filled cookie with another cookie to form a sandwich. Press gently to spread the filling evenly and serve or store for later enjoyment.

Notes

For a gluten-free option, use a gluten-free flour blend in the cookie dough.
Adjust peppermint extract amount according to preference for mint intensity.
Ensure the chocolate mixture has cooled before adding eggs to prevent scrambling.
Cookies can be stored in an airtight container at room temperature for up to 5 days or refrigerated for up to 2 weeks.
Optional green food coloring can enhance the festive appearance but can be omitted if preferred.
