The only thing I can think of is rolos.

I looked at the recipe and think the ingredient is probably milk duds rolo and riesen are too big for the center of a truffle.

Thanks, I think I thought of Rolo, but am not real familiar with them. Is the caramel firm (like the recipe seems to indicate or is it more liquidy? I don't know Riesen, but will look at those, too. Thank you both!

Maybe I should look for a copycat recipe that names the brand of the caramels.

The caramel in rolos is chewy. I imagine it goes to liquid when heated.

Do you have Werther's?

Some of their candies sound somewhat like that here in southern Ontario.

Rolos are common in these sorts of recipes. They do see large but I've never heard of the other's mentioned being baked with......

Rolo comes in a 10.6 oz bag and are described as chewy and in milk chocolate. Must be what they mean

My first thought, like joyfulguy, was Werthers soft toffee caramels. They could be cut to fit.

Werthers soft toffee caramels are not chocolate covered. The caramel would just absorb into the surrounding oreo brownie layer. ( Though that sounds tasty too. )

You can see in the recipe photo that the caramel has a chocolate shell around it. Though they don't mention the brand name of the candy, the reference to the 10.6oz bag is the size of Rolo. I would make it once as written before making any changes.

Pretty sure Werthers has a chewy chocolate version as well, but I would go with Reisen myself.

"Werthers soft toffee caramels are not chocolate covered. The caramel would just melt into the surrounding oreo brownie layer. ( Though that sounds tasty too. )"

This recipe is not baked, so that wouldn't be a problem.

The recipe doesn't say if you include the white 'stuff' of the OREO cookie when you crush them up. I assume you are supposed to include it but maybe not.

My guess is rolos also. I have made these pretzel rolo turtles a few times. Easy and a nice size bite that combines sweet, salty, crunch and flavor. Rolo Pretzel Turtle

I wonder how many they had to cut open to get a truffle showing a perfectly round center (Rolos are more like cylinders than like balls). I wonder who ate the rejects, lol.

I'm thinking there's obviously more than one brand of such a thing.

Trader Joe's has milk chocolate caramels, so do a number of other stores.

P.S. Some of those candies are shaped like balls.

Rolos also come in a mini version called Rolo bites, I believe.

Thanks everyone! I have made the Oreos plain truffles before and, yes, you whirl the frosting into the crumbs, too. With the cream cheese mixed in, as it mellows, the mixture becomes unrecognizable as Oreos. The truffles are truly yummy - I never would have believed it.
Of course, looking at the caramel filled ones, I forgot that the recipe isn't baked because the pic of the cut one looks gooey and slightly runny. So whatever is used has to have the caramel texture just right; it's not going to soften in the oven. I looked at pics of Rolo and since they aren't round, I just don't know. The filling looks right, though.
I agree about wondering how many takes and cuts it took to get that perfect one. But it's probably touched up anyway.
eta: Okay, I just thought to google Rolo stuffed Oreo Truffles recipe and got lots of results so I guess it's Rolos! Thanks again.

I imagine if it was chilled first, the cut would be cleaner...?

Carol, your pic hadn't loaded for me, so I just did a search and posted that exact pic, then noticed yours so deleted mine. I'll check TJ's brand for roundness! I also wondered about Milk Duds, as they came up in my search, but I don't think they are round either?

Yeah - Milk duds are irregularly shaped and more like blobs than anything else.

I did a Google Image search using the term 'milk chocolate covered caramels'.

Try cadbury caramilk… ot sure if available south of the 49th
