In another large bowl, mix butter, cream cheese, and vanilla. Add powdered sugar and mix well.
Add green food coloring and mix once more then set aside.
Add your Oreo cookies to a gallon Ziploc bag and crush them with a rolling pin, set aside.
Take 5 of the plastic cups and divide the pudding evenly between them. Do this again with a layer of crushed Oreo cookies.
Next, pipe your green icing "grass" for each cup.
Top with a Peeps bunny and enjoy!
