Prepare pudding according to package directions and place in the fridge to set.
Process chocolate cookies in a food processor and spread evenly on the bottom of a 9×13 pan. Spread pudding evenly on top of the chocolate cookie layer.
In a separate bowl, combine sweetened condensed milk, cool whip and cream cheese. Beat until smooth. Add a few drops of green food coloring. (This will be the grass layer.) Smooth cream cheese mixture over pudding layer.
Crush white sandwich cookies in food processor until crumbs and then toss with green food coloring until it matches the color of the cream cheese mixture. Then spread over Cool Whip layer.
Chill this dessert in the fridge for 15 minutes or until ready to serve.
Garnish with Cadbury eggs and Peeps (the kids will love helping with this part!)
