Chocolate Bars

Butter and line a 10-15 cm cake pan with baking paper. In a saucepan, melt the butter, sugar, and cocoa. Stir in the leftover crushed cake, biscuits, cookies.

Pour the mixture into the prepared cake pan, smooth the top with the spatula. Melt the chocolates using a bain-marie technique.

Pour melted chocolates over the mixture in the cake pan. Use a spatula to smooth it, so it's entirely covered in chocolate.

Before the chocolate has frozen, sprinkle the broken hazelnuts on it speedily.

Put the cake pan in the fridge and let it wait for about 3 hours. After taking it out, let it wait for 15 minutes, cut it and serve.
