That's essentially what we call pancakes in the UK (though confusing, there are also 'Scotch Pancakes'). British pancakes can be sweet or savoury though so you don't usually include sugar, and they don't typically contain butter either AFAIK. The batter is just the same as used for Yorkshire Puddings.

Edit: those downvoting care to give any reason? My comment is essentially factual AFAIK so I'm not sure what that is all about.
