'ice cream' or 'an ice cream'

[wotcha]

Is it usual to say 'an ice cream' or 'two ice creams'?

My dictionary ways 'ice cream' is an uncountable noun, but I've seen a lot of examples of putting an before 'ice cream' in books.

'I'd like an ice cream' is not particularly informal. Like many nouns, 'ice cream' can be countable or uncountable, depending on what is meant.

"I'll get us some ice cream for pudding." - a tub
"I like ice cream." - the food product.
In a restaurant: "Two ice creams please." - portions
"Luke ate three ice creams yesterday afternoon."- ice creams

This example might not be understood by most speakers of AmE.
It seems that in BrE, pudding can be used as a synonym for dessert, while in AmE, it refers to a specific type of dessert.
