Black And White Cheesecake - cooking recipe

Ingredients

176 g Oreo biscuits
40 g butter, melted
350 g cream cheese
200 g sour cream
1/2 None lemon, zested
2 1/2 tbsp custard powder
1 tsp vanilla essence
50 g caster sugar
100 g dark chocolate
100 g double cream
75 g white chocolate

Preparation

Preheat oven to 350\u00b0F. Crush all but 3 of the cookies into crumbs and mix with the melted butter. Press 2/3 into the bottom of a lined 8 inch springform cake pan and smooth out.
Mix together the cream cheese, sour cream, lemon zest, cornstarch, vanilla extract and sugar. Spread half over the base, add the remaining cookie crumbs and top with remaining cream cheese mixture. Smooth the top and bake for about 1 hour. Remove from the oven and allow to cool on a wire rack for about 2 hours.
Melt the dark chocolate and mix with 1/3 cup of cream until well combined. Melt the white chocolate and mix with the remaining cream. Spread the dark chocolate all over the cake, drizzle the white chocolate over the top and use a toothpick to create patterns. Roughly chop the 3 remaining cookies and use to decorate around the side.
