Homemade Ice Cream Birthday Cake

This is an easy, affordable and impressive ice cream birthday cake.
The first thing I did was line a spring form cake tin with baking paper.
I then used 3/4rd of a packet of plain chocolate biscuits and 60g melted butter to make my base. Just blitzing them with the handheld blender. I then spooned this mix into the tin and pressed it to a consistent base.
I started with 2 litres of neapolitan ice cream. I allowed it to soften and then divided it up.
For the 1st layer, the bottom layer, I used all the pink and half the white. I mixed in diced up turkish delight and spooned it in. I then put the cake back in the freezer while preparing the next layer.
Layer 2 was just plain vanilla ice cream, I used approximately 750g of ice cream from a different tub, about 4 large scoops, to get a layer about 3 cm thick.

For Layer 3 I then used the rest of the vanilla and all the chocolate from the neapolitan tub. I mixed it together with 5 crushed caramel Tim Tams. I then covered the whole cake with cling wrap and foil and put it in the freezer overnight.
Ye gods! This is not good for the waistline, but sounds oh so yummy!
