Somewhere right now, a woman is standing in the Costco bakery aisle with a phone in one hand and a cart she swore would only hold paper towels and rotisserie chicken. She leans in, reads the label twice, and quietly tips a long pink-and-cream box on top of the bulk almonds. She did not come for cake. She is leaving with cake. This is how it goes with the Kirkland Signature Waffle Cone Bar Cake, the bakery drop that turned a routine warehouse run into an event and lit up dessert corners of social media in summer 2026.
If you have not seen the videos yet, picture the nostalgia of a sugar cone melting in the sun, rebuilt as a sliceable sheet cake big enough to feed a backyard. That single idea is doing a lot of work. It is the kind of treat that makes you want to gather people, and for a body-positive table where dessert is a joy and not a negotiation, that is exactly the energy we are here for. Let us walk through what this cake actually is, why it spread so fast, and how to recreate the whole vibe in your own kitchen when the cake is sold out or simply not near you.
What the Waffle Cone Bar Cake Actually Is
Strip away the hype and you are looking at a generously layered sheet-style dessert that borrows its entire personality from a classic ice cream waffle cone. According to coverage from outlets including Parade, Tasting Table, and The Daily Meal, the cake is built from spongy layers of waffle-cone-flavored cake, a crunchy waffle cone crumble worked through the middle, and a heavy, creamy filling that does the work of standing in for soft serve. The top gets a swirl of chocolate and caramel, then it is finished with three mini chocolate-filled waffle cones perched on top like the dessert is wearing a little crown.
It carries the item number 2056615 and lands in Costco’s bakery case at roughly 40 ounces, billed as around a 12-serving cake. The flavor that everyone keeps trying to describe comes down to what a waffle cone tastes like in the first place: vanilla, caramelized sugar, a little toasty butteriness, the warm edge of something baked until golden. Put that into a soft sponge and it reads as comfort food the second it hits your tongue.
The detail reviewers keep circling back to is texture. Early shoppers reported that the waffle cone pieces hold their crunch better than you would expect from something sitting in a creamy filling, which is the make-or-break for a treat like this. Nobody wants a soggy cone. The fact that it stays snappy is half the reason people are obsessed.
Why It Went Viral
Costco cakes have a built-in fan base, but this one caught a particular wave. A Costco-spotting account on Instagram known as costcohotfinds was among the first to surface the cake, and that post took off in a way that bakery items rarely do, racking up thousands of likes, hundreds of comments, and tens of thousands of shares. Once one account makes a find look irresistible, the algorithm does the rest, and suddenly every dessert lover on your feed is asking which warehouse has it in stock.
The comments tell the story better than any marketing copy could. Shoppers called it next level. One person wrote that it tastes just like ice cream, no joke. Another simply said it was SO good. People started saying they wanted to buy two at a time, which at a warehouse store is both a joke and a genuine plan. There is also a quieter thread of feedback worth naming honestly: some shoppers wished the bakery used cleaner ingredients, a fair point that comes up with a lot of large-format grocery desserts. Naming that out loud is part of why the DIY versions below matter, because making it yourself means you decide what goes in.
The other engine behind the buzz is scarcity. Reporting suggests the cake has been showing up in select locations rather than nationwide, with early sightings clustered in states like Pennsylvania, North Carolina, and Ohio, and it appeared to sell out online quickly. It also reads as a seasonal, summer-leaning release rather than a permanent fixture. Limited availability plus a treat that photographs beautifully is a recipe for exactly this kind of frenzy. When something feels like it might vanish, everyone wants it more. And because the cake leans so hard on a shared childhood memory, the videos do double duty: they sell the dessert and they sell a feeling, that first lick of soft serve on a hot day when you were small enough that summer felt endless. A treat that delivers both flavor and nostalgia in one slice is exactly the kind of thing people tag three friends under and screenshot for the next shopping list.
What to Know Before You Buy
A few grounded notes so your trip is a win and not a letdown.
Price first. Several outlets and a warehouse-tracking listing have reported the cake at approximately $18.99, though pricing can shift by region and over time, so treat that as a ballpark rather than a promise. For something that serves around a dozen people, that still lands in the friendly range for feeding a crowd.
Availability second. Because it has been turning up in select stores, call ahead or check a Costco-finds account for your area before you drive across town. Bakery stock moves fast on a viral item, and a quick call to the bakery counter can save you a sad empty-handed walk back to the car.
Serving third. This is a rich cake. The creamy filling and the chocolate-caramel swirl mean a little goes a long way, so those 12 servings are real servings, not slivers. It holds up best cold, straight from the fridge, which also keeps that signature crunch intact. If you are bringing it to a summer party, keep it chilled until the last possible moment.
And one gentle reminder for our table specifically: this is a treat, and treats are allowed to just be delicious. You do not owe anyone an explanation for buying a fun cake. Slice it, share it, enjoy the nostalgia, and let it be uncomplicated.
A DIY Waffle Cone Layer Cake You Can Make at Home
Maybe the cake is sold out. Maybe the nearest Costco is a haul. Maybe you simply want to control what goes into it. Good news: the whole concept is recreatable with grocery-store basics, no special partnerships or hard-to-find products required. Here is a workable home version that captures the spirit – toasty waffle cone flavor, creamy filling, crunch in every bite.
What you will need:
- 1 boxed yellow or vanilla cake mix, plus the eggs, oil, and water it calls for (or your favorite from-scratch vanilla cake recipe)
- 1 teaspoon vanilla extract, plus an extra splash for the frosting
- 4 to 6 store-bought waffle cones or sugar cones
- 2 cups heavy whipping cream
- 1/2 cup powdered sugar
- 1 jar caramel sauce
- 1 jar chocolate fudge or ganache-style sauce
- A handful of mini ice cream cones for the top, if you can find them
How to bring it together:
- Make the cake batter per your recipe, then stir the vanilla extract into the batter. For an extra layer of waffle cone character, crush two cones into fine crumbs and fold a few tablespoons into the batter before baking. Bake in two round pans or one rectangular pan and cool completely.
- While it bakes, make the filling. Whip the cold heavy cream with the powdered sugar and a splash of vanilla until it holds firm peaks. This is your stand-in for that creamy soft-serve layer.
- Crush the remaining cones into a mix of fine crumbs and bigger crunchy shards. Keep them separate from the wet ingredients until the last minute so they stay crisp.
- Slice the cooled cake into layers. Spread the whipped cream filling between layers and sprinkle the cone crumble over each layer of cream as you stack.
- Finish the top with a generous drizzle of caramel and chocolate sauce, swirled together with the tip of a knife. Scatter the remaining cone shards over the top, and crown it with a few mini cones if you have them.
- Chill at least an hour before serving so it slices cleanly and the crunch holds. Add the final crumble right before it goes to the table.
The trick that makes or breaks the homemade version is the same one that made the original go viral: keep the crunchy elements dry and add them late. Stirred-in crumbs soften; crumbs added at the last moment stay snappy.
No-Bake and Lighter Riffs on the Same Idea
Not every summer day is a turn-on-the-oven day, and not every craving needs a full layer cake. The beauty of the waffle cone concept is how flexible it is, so here are a few easier paths to the same flavor.
Waffle cone icebox cake. Layer graham crackers or thin vanilla wafers with the same sweetened whipped cream and cone crumble in a loaf pan or baking dish, then refrigerate overnight. The cookies soften into cake-like layers while the cone bits stay crunchy. Drizzle caramel and chocolate on top before serving. Zero baking, and it slices beautifully.
Single-serve trifle jars. Spoon cubed vanilla cake (store-bought pound cake works great), whipped cream, cone crumble, and a swirl of caramel and chocolate into small glasses or mason jars. These are perfect for a cookout because everyone gets their own, and they look like a million dollars for almost no effort. They also let people choose their own portion, which is a small kindness at any gathering.
A lighter take. If you want some of the joy with a little less richness, swap part of the whipped cream for whipped Greek yogurt sweetened with a touch of honey, and lean on fresh sliced strawberries or peaches between the layers. You keep the waffle cone crunch and the summer feeling while lightening the load. This is not about shrinking the treat or apologizing for it, just offering a version that might sit better on a hot day or fit a different mood.
Make-it-yours add-ins. A handful of mini chocolate chips, a spoonful of crushed toffee, a few fresh raspberries, or a dusting of flaky sea salt over the caramel all play beautifully with the toasty cone base. This is the part where you stop following anyone’s recipe and start making it yours. Half the fun of a viral dessert is the remix, and nobody is keeping score on whether your version matches the box on the shelf.
Bringing the Whole Vibe to Your Table
Here is the real reason a sheet cake shaped like a melted ice cream cone became the dessert of the summer: it gives people permission to gather. A 12-serving cake is not a thing you make for one quiet evening. It is a thing you make because the cousins are coming over, because it is somebody’s half-birthday, because the weather finally turned and everyone is outside until the streetlights come on.
So lean into that. Set the cake out where people can see it and circle back for seconds. Put a stack of small plates next to it and let folks cut their own slice as big or as small as they want. Pour iced coffee or cold brew alongside it, because the caramel-and-cone flavor practically begs for it. If kids are around, let them be the ones to place the mini cones on top, because that is the kind of small job that turns a regular afternoon into a memory.
Whether you snag the real Kirkland Signature version on a lucky warehouse run or build your own from a boxed mix and a box of cones, the point lands the same way. Dessert is one of the most generous things we make for the people we love. A cake this happy, this nostalgic, and this unbothered by being over the top deserves a table full of people who are equally unbothered about reaching for a second slice. Set it down, hand out the forks, and let summer do the rest.
