Step-by-step instructions

   Pour the mixture into the prepared tin and press it, then smooth the top with the back of a spoon. In the microwave melt both chocolates in short 20‑second intervals, stirring frequently until melted. Pour them over the mixture in the tin. Use a spatula or spoon to spread so everything is fully covered with chocolate.
