  • 2 cups (12 ounces) semisweet chocolate chips
  • 2 eggs
  • 1 tsp vanilla extract

Instructions

  1. Preheat the oven to 350°
  2. Melt the butter over medium-low heat in a small saucepan. Add the brown sugar, water, and chocolate chips. Decrease the heat to low and stir often until the chocolate chips are melted. Set aside to cool for about 15 minutes or so. Whisk in the eggs and vanilla extract.
  3. In a separate bowl, combine the flour, baking soda, and salt. Gradually add to the chocolate.
  4. Use a spoon or cookie scoop to drop small tablespoons of cookie dough onto ungreased baking sheets. Bake for 10-12 minutes or until firm. Place on a wire rack to cool.
  5. Cool completely before adding the filling.

  7. Mix the confectioners’ sugar, softened butter, milk, peppermint extract, salt, and food coloring until smooth. Spread over the bottom of half of the cookies, then top with the rest of the cookies.
