13 Sonic Shakes, Ranked

Nowadays, picking up food often means zipping through a drive-thru as quickly as possible and racing home to dig into your to-go bag of grub. But Sonic does things a little differently. Yes, the drive-thru option is there, but you can also pull in and stay awhile, taking a trip back in time to the days of old-school drive-ins. The chain is keeping this tradition alive and giving us all a taste of nostalgia — literally. Its menu is packed with classic comfort foods like juicy burgers, french fries, and chili cheese dogs. And, don't worry, they didn't forget about the milkshakes to wash everything down.

At Sonic, shakes can be found in the sweets section of the menu, alongside Sonic Blasts and sundaes. They're actually separated into two different categories as well: Classic Shakes and Master Shakes. The classic recipes keep things simple by sticking to just one flavor add-in. Think vanilla, chocolate, and peanut butter. Master Shakes, on the other hand, are a little more elaborate with ingredients like cookies or even cheesecake. Both have their own time and place, but at the end of the day, which shakes are really the best?

To find out, I tried all 13 of Sonic's current milkshake options, including the seasonal Banana Pudding flavor. I judged each one based on its consistency, sweetness level, and the flavor and cohesiveness of its mix-ins. With all of that in mind, I ranked every shake from my least favorite to the one I'd happily sip on again and again.

I couldn't wait to get my hands on this one, and then it supremely let me down. I expected a sippable rendition of the creamy pudding I used to enjoy so much growing up. A pudding stuffed with ripe banana slices and topped with a generous amount of sweet Nilla wafers. What I got was a sour, fake banana mess.

I'm convinced no real bananas were used in the making. Instead, banana pudding flavoring is combined with vanilla soft serve. You can tell something isn't quite natural just by looking at the bright yellow color around the edges of the cup, where the flavoring hasn't fully mixed in. It tastes more like banana Laffy Taffy than actual fruit. But even worse than that artificial sweetness was some kind of sourness. I'm not sure where it was coming from, but it ruined the shake before I could even swallow my first gulp.

The best thing about this one was the vanilla wafer cookie crumbles sprinkled over the whipped cream. But even those were a bit too stale for my liking. Far from deliciously nostalgic, the entire milkshake landed in my last-place spot.

Caramel isn't a flavor I would have expected to find on a classic milkshake menu. It is often associated with ice cream, sure. But more so as a topping, drizzled onto an awaiting sundae or added as a finishing touch. Blended right into a shake is somewhat new for me. New and not exactly a new favorite.

It combines vanilla soft serve with a caramel flavor and finishes things off with a dollop of whipped cream and a cherry. It sounds fine and dandy, but what Sonic doesn't tell you is that it's more like salted caramel, and there's a lot of it poured in. It's a little too salty, a little too cloyingly sweet all at the same time. With the thicker consistency of the shake, it felt like I was slurping up straight caramel syrup at times — like the stuff you would find at the bottom of your caramel Frappuccino or the Caramel Ribbon Crunch Frappuccino (yes, there's a difference). Some people may think that sounds divine. But for me, it was a sticky-sweet caramel surprise that caught me off guard. And not in a good way.

Now, strawberry, on the other hand, is something I absolutely expected to see. It's a core shake flavor, right alongside vanilla and chocolate — the Neapolitan trio.

Rather than using strawberry ice cream as its base, Sonic blends real strawberries into its classic vanilla soft serve. This would be fine, but it feels like the chain is playing it fast and loose with the word "real." Even though there are strawberry remnants throughout, they have a surprisingly artificial taste. Overall, the flavor is more like a concentrated strawberry coulis than fresh fruit. It's very strawberry-y, to say the least. Subtle is not in this milkshake's vocabulary — except maybe when it comes to describing its pale pink hue.

The worst part, though, is that the aggressive strawberry flavor seems to linger at the back of your throat. That, and the shake itself doesn't seem to be nearly as creamy as some of Sonic's other options. So it only manages to beat out the salty caramely option, but only by a small, strawberry-sized margin.

Cheesecake plays a major role in Sonic's "Master" milkshake line. In fact, it appears in three out of those six Master flavors — a 50% takeover. Someone must really like cheesecake on Sonic's product development team.

So does the chain stuff an entire slice of cheesecake into the blender for all those shakes? No, it relies on a cheesecake syrup instead. That's not a problem. I wasn't expecting anything fancier anyway. But you don't really get to taste it much here. Those real strawberries from the classic strawberry shake are back, and their flavor is still just as strong. That almost fake strawberry taste is still running the show, though it does seem just a tad more mellowed out this time around. To say that I could actually taste the tang of the cheesecake syrup would be a bit of a stretch. But it feels like it may be doing something in the background to help this shake out.

That said, it does end up surpassing the classic strawberry, though not by much. They also forgot the graham cracker crumbs I was supposed to get on top, so I didn't even get that simple cheesecake pleasure.

Just a plain Jane vanilla shake. I'm sure it gets skipped over on menus a great deal in favor of something flashier and more dressed up. But sometimes just a standard vanilla can really hit the spot.

Unfortunately, Sonic's take only halfway hits the spot. It just doesn't quite compare to other top-notch fast-food vanilla milkshakes I've had in the past. The initial smell is more like vanilla protein powder, and it's missing that rich butteriness that makes a really good vanilla shake taste so indulgent. The sweetness is at a good level, though, and the vanilla flavor itself tastes somewhat authentic. What's hiding behind it, however, is just a slight hint of a chemical taste. It's something that could very well be present in all of Sonic's shakes — perhaps coming from the soft serve itself. But it's only noticeable here because the vanilla shake is so stripped down, without any additional syrups or flavorings to mask it.

Really, it boils down to being pretty unremarkable. It doesn't stand out within Sonic's own milkshake collection or against other vanilla milkshake recipes.

It's obvious that the banana pudding milkshake and the banana milkshake were not made the same way. This one ditches the banana pudding flavoring (and the vanilla wafer crumbles on top) and instead uses just bananas blended with vanilla soft serve. And this swap makes all the difference.

The sourness from the banana pudding shake is gone, along with most of that artificial taste. It actually tastes like real banana ... for the most part. There's still a tiny bit of weirdness to it, and I didn't come across any actual banana chunks to help prove its authenticity. That's part of why I don't have it ranked terribly high, but the flavor is still miles better than its pudding counterpart.

The fruit flavor is more subtle here, and it's actually a really great match for the creamy vanilla base. I would happily sip this one again, though it wouldn't be my absolute first choice. And if you're still craving that banana pudding essence, you could always try asking for extra whipped cream and vanilla wafer crumbles on top of this classic shake instead.

They teach you not to judge a book by its cover. But I think you can tell a lot about a milkshake just by the way it looks. And what this chocolate shake is telling me is that it's not overly chocolatey. Its very light brown color is a pretty clear indicator of that, and what do you know? The flavor matches the shade.

Made with chocolate sauce and vanilla soft serve, it's far from the most indulgent fast food chocolate shake I've ever had. It could use another pump of what tastes like Hershey's syrup to really give it that full chocolate flavor. Because it doesn't quite deliver in that department, I couldn't justify placing it too high in my taste test.

But it's still a pretty good shake. It has a really nice thickness to it, along with an almost malty flavor that I really liked. If you're all about that and don't mind a more subdued cocoa taste, then by all means, grab yourself a straw and have at it.

I already knew I was going to like this one. I'm all in on peanut butter, and I think it's pretty hard to mess up a combination of vanilla soft serve and the salty spread.

Sure enough, Sonic didn't disappoint. It tastes just as expected. It feels more like a peanut butter sauce has been swirled into the shake, but it's just sweet enough, with a nice balance of those toasted, nutty flavors. Perhaps the best part, though, was getting a swig of both the peanut butter shake and a little bit of whipped cream. Together, they tasted just like a Fluffernutter — that peanut butter and marshmallow fluff sandwich combination that really tugs at my heartstrings, even though I'm not from its birthplace of Massachusetts. 

It's a really good shake, but I did find myself wanting just a little something extra. Maybe a few bits of Reese's Peanut Butter Cups to give it some texture and life? I know this is designated as a classic milkshake, so it's meant to be simple. But I think a little something else would really make it pop and help it climb even higher in my rankings.

It looks like another boring old chocolate shake, but it's much more than that. It's actually made with hot fudge rather than chocolate sauce (as you could probably guess from the name).

As was the case with caramel sauce, I can't say I've ever tried hot fudge blended right into a shake. I wish I'd thought of it, though, because this turns out pretty tasty. It's a bit richer than Sonic's standard chocolate shake, with that extra fudgy note coming through. It's still not overly chocolatey by any means. I think the vanilla soft serve keeps it from tipping over the edge. But it's at least stepping closer to that territory of pure indulgence. Really, it's a twist on a classic hot fudge sundae, only spun up into a treat you can drink through a straw. You even get an extra glob of hot fudge on top, so you can finish off the shake with one last sweet goodbye.

Think of this as your classic cookies and cream milkshake, but taken a step further. Real Oreo cookie pieces are added to the vanilla soft serve, just as you would expect. But then, Sonic also levels things up with a hit of chocolate syrup.

If you're thinking that extra sauce is going to throw everything out of whack and make the shake far too rich (like I was), don't worry. It doesn't. The chocolate is kept really light, just as it was in Sonic's standard chocolate shake, so there's still a really nice balance here. That chocolate sandwich cookie flavor remains the star, with just a mild chocolate backbone to support it.

It's dense and velvety, and it's one I really enjoyed. The cookie bits did get lodged in my straw on more than one occasion. But honestly, I wasn't mad about it, because once they finally come through, you're rewarded with that softened Oreo texture and flavor that's almost as good as dunking one in a glass of milk.

The cheesecake syrup is back, but this time it's riding solo. And I think that was a very good decision. Without those overpowering strawberries weighing it down, it turns out to be a really good milkshake. You can actually taste the cheesecake flavor here, and it's rich and tangy, with a definite cream cheese edge. Mixed in with the vanilla soft serve, it really nails that classic cheesecake taste. I also actually got my sprinkling of graham cracker crumbs this time around, which helped complete the whole cheesecake experience. The dollop of whipped cream on top certainly didn't hurt either.

When you think about it, this shake is pretty simple. With just one main flavoring added to the vanilla soft serve, it feels more like one of Sonic's classic shakes than something from its Master lineup. But I would still count this as a unique milkshake. It's not a flavor you see at just any ice cream shop, and that's why it lands as one of my top picks. Something a little different and done right.

This is exactly what was missing from the classic peanut butter shake. I knew that peanut butter flavor needed a little something extra to feel complete, and Oreos fill that role splendidly. You get that perfect combination of peanut butter and chocolate, something you can never really go wrong with. All that salty richness of the thick peanut butter shake is still there, only now it's complemented by frequent bits of softened chocolate cookies. It's like the best of cookies-and-cream and peanut butter ice cream crammed into one cup.

I also couldn't help but think of "The Parent Trap" as I sipped — the Lindsay Lohan version, of course. There's that scene where both twins confess to eating Oreos with peanut butter. They treat it like a quirky combination that other people might scoff at, but here, it feels so right. They (she?) were definitely onto something.

I have no notes here. This was my absolute favorite milkshake by a landslide. A landslide of yummy cheesecake flavor and Oreo bits, that is.

This is an even better pairing than Oreos and peanut butter, which is saying something because I also loved that matchup. Maybe it's because this one leans a little less salty and rich and more sweet with a tang, making it feel just a little more elevated. Everything I enjoyed about the plain cheesecake milkshake is still here, only now you get that cookies-and-cream essence on top of it. There are just enough softened Oreo cookies scattered throughout, and the shake works out to just the right consistency — creamy yet still perfectly sippable.

It really is the best of both worlds, where neither ingredient overpowers the other. And guess what? You still have the graham cracker dusting on top of the whipped cream to make it even easier on the eyes and taste buds.

I actually took two different trips to Sonic to try every single milkshake on its current 2026 menu. In one go, I knocked out all seven Classic Shake flavors, then went back to pick up the remaining six Master Shake flavors, including the seasonal Banana Pudding flavor (one I would later regret including). That added up to 13 shakes total, and many, many sips later, I started arranging each shake in order of my personal preferences.

Every single milkshake is spun up the same way, with vanilla soft serve as its base. Sonic doesn't scoop hard ice cream into a blender, so most of its shakes end up with a consistency that's creamy and smooth but not terribly thick. That meant most of my attention was focused on the add-ins themselves. I first evaluated each flavor's authenticity — whether banana tasted like real banana, strawberry like real strawberries, and so on. This is an important distinction between an okay shake and a really tasty one. Then, I considered the amount of syrups, candies, and other mix-ins, noting whether they felt skimpy or, conversely, overwhelming. You want a shake that lands somewhere in the middle so it doesn't become overly sweet or cloying.

Lastly, cohesiveness was important. I also favored shakes that offered something different from the same old flavors you see over and over again at other fast food restaurants. If a shake can be unique and delicious at the same time, that's the one I'm going to pick every time.
