  9. To assemble: Roughly chop 1 box of Thin Mint cookies. Starting with the first layer of cake, spread about ¼ cup of frosting across the top. Sprinkle ⅓ of the chopped cookies in the middle of the layer, leaving a ½ inch border around the edge. Top with the next layer of cake and repeat this process 1 more time then top with the last layer of cake. Cover the whole cake with the mint frosting. Using a medium star tip, pipe along the top edge of the cake with more mint frosting. Place whole Thin Mints along the edge on top of the piped frosting.
