'Heißhunger' (craving) is made up of 'heiß' (hot) and 'Hunger' (hunger). The adjective 'heiß' is used here figuratively to mean 'intense' or 'burning' and strengthens the feeling of hunger.
Mitten in der Nacht wachte ich mit einem Heißhunger auf.
In the middle of the night, I woke up with a craving.
When you want to say what you have a craving for, you use the preposition 'auf' followed by the accusative. The typical construction is 'Heißhunger auf etwas haben' (to have a craving for something).
Schwangere haben oft Heißhunger auf saure Gurken.
Pregnant women often have cravings for pickles.
The most common verbs used with 'Heißhunger' (craving) are 'haben' (to have), 'bekommen' (to get), or 'verspüren' (to feel). To end the feeling, you can say 'seinen Heißhunger stillen' (to satisfy one's craving).
Nach dem langen Spaziergang bekam ich plötzlich Heißhunger.
After the long walk, I suddenly got a craving.
desire / pleasure
'die Lust' and 'der Heißhunger' can both describe a desire for something, especially food. 'Lust' is more general and often not as strong: you want to eat, drink, or do something because it sounds pleasant. 'Heißhunger' is much stronger and almost always refers to food. It often comes on suddenly and feels urgent. So you can have 'Lust auf Schokolade' (feel like chocolate) without really having 'Heißhunger' (a craving). 'Heißhunger' fits when the desire is very strong.

After exercising, Tom suddenly had a craving for pasta.
