Hello ManishaMehta
Your cake became hard because it was refrigerated. If you used butter that will have solidified, exactly in the same way as butter does when placed in the fridge. If your cake was rubbery this may have been caused by your oven temperature being too low or if it had not been properly pre heated.
The chocolate tranfer triangles may have broken because the melted chocolate layer was not thick enough. If you make them again spread the chocolate evenly and not too thin.
