Step 1: Prepare the Cookie Base

1. Place the chocolate sandwich cookies in a large ziplock bag and crush them using a rolling pin until they become fine crumbs. Alternatively, pulse them in a food processor.
2. Transfer the crushed cookies to a bowl and mix with the melted butter until well combined. The mixture should resemble damp sand.
3. Press the cookie mixture evenly into the bottom of a 9×13-inch casserole dish. This will form the crust. Set it aside while preparing the filling.

Step 2: Make the Creamy Filling

1. In a large mixing bowl, beat the softened cream cheese and powdered sugar together until smooth and fluffy.
2. In a separate bowl, whisk the cold milk and instant chocolate pudding mix for about 2 minutes, until it thickens. Let it sit for a few minutes to fully set.
3. Stir the vanilla extract into the pudding mixture, then fold in the whipped topping until well combined.
4. Gently fold the pudding mixture into the cream cheese mixture, stirring until smooth and creamy.

Step 3: Assemble the Layers

1. Spread half of the pudding mixture over the cookie crust, smoothing it out evenly.
2. Sprinkle half of the remaining crushed cookies over the pudding layer.
3. Spread the rest of the pudding mixture on top.
4. Finish by sprinkling the last layer of crushed cookies over the top, creating the “dirt” effect.

Step 4: Add the Easter Decorations

1. If using shredded coconut, place it in a small bowl and add a few drops of green food coloring. Stir until the coconut turns a grassy green color.
2. Sprinkle the green coconut over the top layer of cookie crumbs to create an edible “grass.”
3. Arrange chocolate eggs, chocolate bunnies, and marshmallow peeps on top to create a festive Easter garden look.

Step 5: Chill and Serve

1. Cover the casserole dish with plastic wrap and refrigerate for at least 2 hours to allow the flavors to meld and the dessert to set.
2. Once chilled, serve with a spoon, scooping out generous portions onto plates. Enjoy your Easter Dirt Cake Casserole!
