Volcano Cake Bundle – Allergy-Friendly Jumbo Cakes with San Antonio Delivery
For years, our Volcano Cakes have been the go-to add-on for SRVB fans — a gift-worthy indulgence that locals love just as much as our nationwide customers. These jumbo cupcake-sized cakes start with the same tender, flavorful bases as our Naked Cakes, get topped with a generous swirl of frosting, and hide our signature surprise: a thick, creamy buttercream center. That’s the “volcano” — frosting both on top and inside, for double the indulgence. Whether you’re celebrating a birthday, saying thank you, or treating yourself, they’re a San Antonio favorite for a reason.
Allergen-friendly (no dairy, eggs, nuts, or soy) and fully vegan, each 6-pack is baked fresh and individually wrapped for maximum freshness.
Local Delivery Orders: Choose all one flavor or mix and match your favorites.
Facebook Shop Orders: Receive one of each flavor + two baker’s choice from our four flavors (due to platform limits).
The Variety 6-Pack is also the perfect way to sample all our cake bases before picking your Naked Cake for your next big celebration.
Frosted Top + Filled Center — The double treat that makes them true “Volcano Cakes.”
💰 Upgrade & Save — Make it a full dozen Volcano Cakes and save $15. Perfect for parties, office treats, or gifting!

Why are they called “Volcano Cakes”?
Why are they called “Volcano Cakes”?
Great question! We call them “Volcano Cakes” because they’re erupting with flavor! These jumbo cupcakes have a frosting core—rich, indulgent, and insanely delicious.
How big is a Volcano Cake?
How big is a Volcano Cake?
They’re jumbo-sized, about 3.5-4 inches across — bigger than your standard cupcake.
Do I need to keep them refrigerated?
Do I need to keep them refrigerated?
If you’re not devouring them immediately (hard to resist!), yes, keep them in the fridge. At room temperature, they’ll remain good for about a day (since the filling is creamy, we prefer not to leave them out longer than ~6-8 hours). In the refrigerator, they stay fresh for about 5 days. For longer storage, you can freeze them for up to 3 weeks. Just thaw in the fridge overnight or on the counter for an hour when you’re ready to indulge. Many customers actually enjoy them slightly chilled, as the texture of the frosting is firmer and almost like ice cream.
Do you have gluten-free options?
Do you have gluten-free options?
We’re always testing gluten-free recipes, but we won’t release them until they’re up to our high SRVB standards. They’re in development — no launch date yet.

Are the Volcano Cakes frosted on top?
