  7. Fold in the crushed Oreos and mix until just combined. Do not crush the oreos completely, there should be some bite sized pieces
  8. Divide the mixture evenly into the cake pans.Bake for 25-35 minutes until done
  9. Allow to cool for 20 minutes. Demould and cool completely

  11. Beat the butter until light and fluffy. Add the confectioners' sugar and cream and mix.
  12. Reserve about half or less buttercream for the design. The design can be done as desired. I have used green gel colour with piping tip shown in pic. Add green colour to this mixture and blend well
  13. Mix in the crushed Oreos into the remaining batch of buttercream. Blend well
  14. Place first cake on serving plate and apply frosting on the top
  15. Place second layer of the cake and frost on top and sides
  16. Chill cake for 45 minutes once crumb coat is done. Do final coating and smoothen it
  17. Using buttercream, stick m&m or dairy shots on cream portion of Oreo . For Antenna, I have used toothpick
  18. Stick eyes on the cake as shown
  19. Now start piping on the cake, even if it isn't perfect doesn't matter as this is Monster cake. Place Antennas on top. Cake is ready to be gorged on
