I find if the butter is too soft or melting when I make cookies, they will flatten out when baked, even if the recipe usually makes plump cookies.

What's the recipe? It probably has something to do with the fat to flour ratio or the leavening (baking powder and soda). If you want chubby cookies, try this recipe: http://food52.com/recipes/9209_chubby_chewy_chocolate_chip_cookies
They're awesome!
