Stir in the peppermint essence to the caramel cream mixture.
Stir ⅔ of the crushed peppermint crisps into the cream mixture.
Spoon some of the tennis biscuit crumbs into the bottom of about 8 -12 small glasses depending on the size. Smooth out the surface. Sprinkle some of the leftover peppermint crisp chunks on top of the biscuit base and layer some of the caramel cream mixtures on top. Smooth it out, and repeat with another biscuit layer and a final caramel cream layer.
Finish off with a sprinkling of peppermint crisp pieces.
Refrigerate for 3 hours until the cream is firm.
