I’d say you’re half way there…
Stewart’s made it years ago, I think called peanut butter ripple. I remember because my brother and I would “mine” the ice cream looking for the best “vein”. I can still picture the massive slab of peanut butter we found once–I forget whether we actually came to blows over it. We’d eat all the chocolate ice cream away and then break up the vein into smaller slabs of PB sugarness. Yum.
Here’s a Haagen-Dazs example:
I worked in Baskin-Robbins in hgih school (part of my heritage as a thrid-generation ice cream professional), and I hated people who ordered, say, the hand-packed quarts of that stuff. Maybe my boss had the temperature of the freezer set too low, but the peanut butter froze really hard and was next to impossible to scoop.
On the bright side, I had amazing triceps when I worked there.
My father used to love pistachio ice cream and we used to go to the Howard Johnson’s to buy it in quarts. It was also not available pre-packed, so we had to have the clerk hand-pack it for us.
In Canada (and maybe the US too, I have no idea) Scotsburn introduced a flavour last summer called Chocolate Peanut Butter Parfait that’s pretty much exactly what you describe. I don’t think you can get it in regular size tubs though, just the 16 gallon ones.
Heh. The way I feel about chocolate/peanut butter ice cream, 16 gallons would be just about perfect! 
Why is it that we sometimes think of Dopers at the oddest of moments?

May I direct your attention to… Number 15?
Please, don’t shoot the messenger! It’s for your own good, as my mom would say

No, I think that’s vanilla ice cream with chocolate and peanut butter swirls. They do have one like the OP wants: chocolate ice cream with a peanut butter swirl and mini peanut butter cups. I just got some of this the other night. I can only eat a couple spoonfuls at a time because of the sugar content but it’s good to have around.

Häagen-Dazs makes great-tasting ice cream with an impressively short ingredient list, but that doesn’t make up for the fact that their pints are consistently the fattiest in the freezer.

This reminded me that I once suggested to Ben & Jerry’s that they make a chocolate fluffernutter ice cream. Yeah, chocolate ice cream with peanut butter & marshmallow swirls.
Man, I so want some delicious ice cream, but really. A half-cup serving size? Isn’t that like 2-3 bites? 
Depends on the size of your spoon.
Yes, we used to have a B&J scoop shop in Seattle, and this was my favorite. You could also get pint tubs of any of the scoop flavors. It was especially good when you got an especially large vein of peanut butter, you’d lick of all of the chocolate from around the PB glob, then chew the half-frozen PB.
I just had a flashback to Heavenly Hash. It feels like decades since I’ve had some.
Oddly, that last part is a breakfast I can get behind!!
Oh, and my husband has had the kind devilsknew mentioned - in fact he just finished a carton of it the other day - he says it is TO DIE FOR.
Is this the best time to be asking this question? Maybe you should wait for the recalls to die down first.
I seem to remember when I was a kid Bresler’s 33 Flavors had a chocolate ice cream with peanut butter but without chocolate chips mixed in…not many Bresler’s left in the world though.
