Prep the pan: Use a 9x13-inch dish.
No need to grease it. Clear fridge space for chilling later.
Crush the cookies: Place Oreos in a large zip-top bag and crush with a rolling pin until you have fine crumbs with a few small chunks. Reserve about 1/2 cup crumbs for topping.
Make the pudding: In a large bowl, whisk instant pudding with cold milk for 2 minutes until thickened.
Set aside to continue setting.
Beat the base: In another bowl, beat softened cream cheese and butter until very smooth, about 2 minutes. Mix in powdered sugar and vanilla until fluffy.
Combine filling: Fold the pudding into the cream cheese mixture until fully blended. Gently fold in the whipped topping.
Don’t overmix—keep it airy.
Build the first layer: Sprinkle half of the crushed Oreos into the pan, spreading in an even layer to form the “dirt” base.
Add the cream layer: Spoon all of the filling over the crumbs. Smooth the top with a spatula.
Top with more crumbs: Sprinkle the remaining Oreos evenly over the filling. Lightly press so they adhere without sinking.
Chill: Cover and refrigerate for at least 2 hours, ideally 4 hours.
This helps it slice cleanly and improves flavor.
Decorate for Easter: Right before serving, add candy eggs, pastel sprinkles, and “grass.” To make edible grass, tint shredded coconut with a few drops of green food coloring plus a splash of water, then dry on a paper towel.
Serve: Scoop with a large spoon or cut into squares. Keep extras chilled.
