A punch of refreshing mint taste!
1 Beat together the cream, sugar and mint extract with an electric whisk until the mixture forms stiff peaks.
2 Line a standard 900g loaf tin with parchment paper so that it hangs off the sides.
3 Line the bottom of the tin with the wafer biscuits, creaking them if necessary to fit. Spread a layer of the mint cream mixture over the top. Continue layering, ending with a layer of mint cream, until you reach the top. Sprinkle the top with the chocolate chips.
4 Refrigerate for at least five hours until set.
5 When ready to serve, gently lift the whole cake out of the tin by the parchment paper. Peel off the paper and slice to serve.
