Preheat oven to 350℉ degrees.
Roughly chop 1 cup semi-sweet chocolate chips using a knife, rolling pin, or meat mallet (if not using a knife, place chips in a plastic bag while crushing). Set aside.
Warm the ½ cup unsalted butter (1 stick) in a microwave-safe bowl or saucepan until it’s just melted.
Combine the melted unsalted butter with the ½ cup light brown sugar and ¼ cup granulated sugar in a mixing bowl and use a wooden spoon or spatula to stir them together (*do not use a mixer!).
Next, stir in the 1 large egg, 2 teaspoons vanilla extract, and ½ teaspoon peppermint extract, followed by the ½ teaspoon baking soda and ½ teaspoon salt. Mix in ½ cup Hershey's unsweetened "dark" cocoa powder and 1 cup all-purpose flour until well-combined, then stir in chopped chocolate chips.
Immediately spread dough into a greased 11" cookie cake pan or DIY foil pan.
Bake at 350° degrees with timing dependent on the type of pan (see my DIY foil pan hack in the post above). Bake the center no longer looks super wet.
For metal pan: Bake for 12-14 minutes.
For foil pan (spray foil with nonstick cooking spray): Bake for 16-18 minutes.
Cool completely before spreading on chocolate.
To Make Chocolate:
Add whole 1 cup semi-sweet chocolate chips and ¼ cup unsalted butter i.e. ½ stick[/adjustable] to a small to medium-sized microwave-safe bowl. Heat on 50% power for 30-second increments until fully melted, stirring in between. Microwaving on 50% power is important to melt the chocolate slowly to prevent the chocolate from seizing or burning.
Once melted, add in the ¼ teaspoon peppermint extract and stir. Before spreading, set aside about [adjustable]2[/adjustable] tablespoons of chocolate for the drizzle
Spread melted chocolate over cooled cookie cake until tops and sides are covered. Place the [adjustable]2 [/adjustable]tablespoons of reserved chocolate in a piping bag or ziploc bag with a tiny corner cut off, then drizzle over top for added presentation.
Allow chocolate to harden before cutting, then slice and enjoy!
