Although I recognize the phrase, I have never and would never use it.
Maybe it’s a generational or regional thing. The only person I’ve ever known who regularly called them Toll House cookies was my father, who was born in New England in 1922.
If I’m making them off the Nestle recipe off the bag, they’re Toll House Cookies.
If they’re bought or made from any other recipe, they’re just Chocolate Chip.
A tidbit I learned from a culinary textbook I copyedited many moons ago: The Toll House Cookies recipe on the Nestle chocolate chips package is different from the original Toll House recipe by Ruth Wakefield. So I was thrilled to find a copy of “Ruth Wakefield’s Toll House Tried and True Recipes,” copyright 1936-1940, in a used bookstore, completely by accident. I don’t have a bag of chips in the house, or I could tell you what the differences are. But I can tell you that the recipe is called “Toll House Chocolate Crunch Cookies” in the book, and it calls for “2 bars (7 oz) Nestles yellow label chocolate, semi-sweet, which has been cut in pieces the size of a pea.”
I haven’t gotten around to trying the recipe. I’m thinking I should. (The rest of the cookbook is a hoot. The Roast Turkey recipe begins, “Singe and remove pin feathers, oil bag, tendons, feet, entrails, head and crop.” Thank God for Butterball.)
There are too many recipes that have chocolate chips, chunks, or kisses to not use “cocolate chip cookies” in a generic sense. I’ll refer to the Toll House recipe, if it needs to be specified. Although the original, it is hardly the only.
I had assumed Toll House was a brand.
Chocolate chip is certainly the generic term, BUT…
My mother used to make oatmeal chocolate chip cookies. In fact, she made a hell of a lot more cookies with oatmeal than with flour.
It was normal in my house that when someone said “chocolate chip cookies,” someone would ask “oatmeal or Toll House?”
Well, it can’t possibly call for chocolate chips, because they hadn’t been invented yet. It was several years after the Toll House recipe became famous that Nestle started selling chocolate in ‘chip’ form, specifically for use in the aforementioned cookies.
I only use that name for the ones I make from the recipe on the chip bag. Most of these don’t make it to adulthood, though. They get devoured in their larval dough state. 
Chocolate chips are another oddly named thing, in that they aren’t chips of chocolate, but little drops of semi-liquid chocolate that has cooled.
Growing up in the '70s they were always Toll House cookies. Haven’t thought about that in ages! Now we just say chocolate chip cookies, but I would know what someone meant if I heard it.
Brings back a nice memory to hear that name again!
Yes, my mom baked both chocolate chip and toll house cookies. The toll house contained nuts.
I use the original recipe used by Phobe’s grandmother, Ne-Slay Taul’ouse cookies.
