Prepare the Cream Cheese Mixture
In a large mixing bowl, beat the softened cream cheese and powdered sugar until smooth and creamy.
Gently fold in the whipped topping until fully combined.
Make the Pudding
In a separate bowl, whisk together the instant vanilla pudding mix and milk until thickened (about 2 minutes).
Combine the pudding mixture with the cream cheese mixture, stirring until well blended.
Layer the Dessert
In a 9x13-inch casserole dish, spread half of the crushed Oreo cookies evenly on the bottom.
Pour half of the pudding and cream cheese mixture over the crushed Oreos and spread evenly.
Add another layer of the remaining crushed Oreos on top.
Decorate the Top
Arrange gummy worms and chocolate eggs on top to resemble an Easter-themed garden.
If desired, add fresh mint leaves for a decorative touch.
Chill and Serve
Cover and refrigerate for at least 2 hours to allow the flavors to meld together.
Serve chilled and enjoy!
