Change in entropy that the Universe has to suffer from Ice Cream melting?

If a carton of ice cream is left out of the freezer overnight and completely melts, how do I figure out what the change in entropy that the Universe has to suffer because of this?

The mass of the ice cream = 1 kilogram
Original temp. of ice cream was 0 deg. Celsius, but had heated up to 25 deg. Celsius (room temp.)
The specific heat of the ice cream was 4.18 Joules/gram-deg K
The heat of fusion of this ice cream = 300 Joules per gram.
