Method
Instructions
Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.
Cream together the unsalted butter and granulated sugar until light and fluffy, about 3-4 minutes.
Add the vanilla and the large egg, mixing until fully combined.
Whisk together the flour, cocoa powder, baking soda, and salt in a separate bowl.
Combine the dry ingredients with the wet ingredients, mixing until a soft dough forms.
Roll the dough into about 1-inch balls and place them on the prepared baking sheet.
Bake for 8–10 minutes, watching for edges that appear firm. Let the cookies cool completely.
Beat the unsalted butter for the frosting until creamy. Gradually add in the powdered sugar, milk, and mint extract, mixing until smooth.
Spread a layer of mint frosting over each cooled cookie.
Melt the semisweet chocolate and oil together until smooth for the ganache. Drizzle over the frosted cookies.
Allow the ganache to set completely before serving.
Notes
Optional: Garnish with a sprinkle of crushed mint leaves for an added touch.
