3Add to broken cookies and mix well. Line a bread tin or any freezer safe, long, rectangular dish with grease proof paper, leaving enough over the sides to fold over once filled. Press the mixture into the tin, fold in sides to seal. Place in freezer for at 2-3 hours. If you want a more rounder log shape, don't use the tin, just place the mixture on a sheet of grease-proof paper and the roll the paper up, sealing the sides by tucking under the ends. Once it is sufficiently chilled, remove your "log", slice and enjoy!!!
