Chop up butter into small bits. Stick everything into a saucepan and slowly bring to boil, stirring continuously.
Low Fat / Low Sugar / Low Effort Version
In a big bowl, put all the ingredients together and stir.
Put in a microwave oven to bake at maximum power (I used 12 minutes for a 750 Watts oven).
Stop every 3 min to stir and make sure the semolina is not stuck at the bottom.
Let it cool down and store in the fridge or just scoff it all down.
