Add the dry instant chocolate pudding mix and milk to a large bowl, mix with a whisk until all the pudding has been dissolved, around 5 minutes. Allow the pudding to rest 5 minutes until thickened.
Sprinkle crushed Oreo cookies over the bottom of four small cups. Fill each cup halfway full of pudding.
Top the pudding layer with another layer of crushed Oreo cookies. Fill each cup with pudding, leaving a small amount of space at the top of the cup for decorations. Sprinkle the remaining crushed Oreo cookies over the pudding.
Pour the shredded coconut into a strong zip-top bag and add 3 to 4 drops of green food coloring. Seal the bag and squeeze and shake the bag to coat the coconut shreds evenly in food coloring. Sprinkle the green coconut over the top of each pudding cup.
Press two Peeps marshmallows into the top of each cup, then add three chocolate eggs to each pudding. Serve and enjoy!
