This is a Dirt Cake and is made in a clear container from Michael's or Hobby Lobby. The sunflower is a Silk with leaves. I made a few of these for a graduation party and everyone thought it was a real centerpiece. We had to tell them they could eat it.
Recipe:
1 large pack Oreos, crushed to the consistency that they look like dirt
1 large pkg. of Vanilla pudding made according to directions

Cream Cheese Filling
1 8 oz. bar of cream cheese, softened
1 12 oz. Cool Whip, mostly thawed
1 1/2 cups Confectioners sugar
Beat the above 3 ingredients together with a mixer until smooth.
Layer crushed oreos, cream cheese mixture and pudding, continuing until full with the top being crushed oreos.
You can also make this in a flower pot with gummy worms for children's parties.
