Combine with Butter: In a mixing bowl, blend the crushed cookies with melted butter until thoroughly combined. The resulting mixture should have a texture similar to damp sand and should clump together when pressed.
Press into the Pan: Take a 9x9-inch baking dish and evenly press the cookie mixture into the bottom to form the base layer. Refrigerate for about 15 minutes to set.
Prepare the Cream Filling: In a bowl, beat the cream cheese until smooth. Gradually add powdered sugar, mixing until combined. Add mint extract and green food coloring until well blended.
Incorporate Whipping Cream: Carefully incorporate the whipped cream into the cream cheese mixture, mixing until fully blended.
Layer the Cream Filling: Spread half of the cream filling evenly over the cookie base in the pan.
Add Another Layer of Cookies: Place another layer of crushed mint chocolate cookies on top of the cream filling. Press down gently.
Repeat the Cream Layer: Spread the remaining cream filling over the cookie layer, smoothing it out with a spatula.
Refrigerate: Seal the dish with plastic wrap and place it in the refrigerator for a minimum of 4 hours, or ideally overnight, to achieve the best flavor and texture.
Finish and Serve: Before serving, top the lasagna with whipped cream and drizzle with chocolate syrup.
