Bubble Guppies Cake Pan
Which cake pan will make a fun, recognizable ocean-themed birthday cake without making baking and decorating harder than they need to be?
I’d choose the XIYUAN fish-shaped aluminum pan for the clearest fish outline and a useful leakproof design. If getting the cake out cleanly is your biggest worry, the GXHUANG flexible silicone pan is the easier-style alternative. For a beginner who mainly wants a character image and a straightforward bake, a flat sheet cake with an edible image topper is simpler than shaping and decorating a molded cake.
A Bubble Guppies cake pan isn’t among these options. The closest match is the XIYUAN fish-shaped pan, because its fish silhouette gives you an underwater-party shape to decorate.

#1 · XIYUAN
2 Pieces Simulated Fish Cake Baking Pan Aluminum 3D Animal DIY Cake Mold Baking Pan Kitchen Pudding Jelly Cake Decoration 7.8 inch Food Grade Non-Stick Coating
Choose this for a distinctly fish-shaped cake: its 7.8-inch aluminum mold is described as a one-piece leakproof design, and its non-stick coating helps with release. It’s the strongest fit when the silhouette matters more than having the most forgiving pan to handle.

#2 · GXHUANG
GXHUANG Silicone Cake Pan, 9 Inch, Non-Stick, Heat Resistant, for Ocean Theme Party Cake, Mousse, and Dessert Baking (Shark)
Pick this 9-inch silicone pan when easy release and flexible demolding are your priorities. It suits an ocean-themed celebration and can also make mousse or jelly desserts, but it’s not the pick for a classic fish outline.

#3 · Hyoocct
Hyoocct Fish Cake Baking Pan Cakes Bake Mold - 9 INCH
This is the simpler fish-pan option if you want an aluminum cake mold with a stated 9-inch size and don’t need extra features. Choose it for a straightforward fish-shaped cake, rather than for the more detailed guidance offered by the XIYUAN pan.
Do you want a fish silhouette, or the easiest release?
For a recognizable fish-shaped cake, take the XIYUAN; its one-piece mold design is also intended to keep batter from leaking. For a flexible pan you can peel away from the cooled cake, choose the GXHUANG silicone pan instead. Silicone bends easily, so set it on a firm baking sheet before filling and moving it. If the fish outline is the point of the cake, the XIYUAN is the better match.
How do you avoid sticking in the details?
Grease the corners and narrow sections carefully, even with a non-stick pan, and let the cake cool before turning it out. With the XIYUAN, the coating and leakproof one-piece design make it the more reassuring aluminum choice; with the GXHUANG, flex the silicone away from the cake rather than pulling the cake by its thin parts. For the least fussy release, I’d pick the GXHUANG.
Is a shaped cake worth the extra decorating work?
A molded cake gives you a three-dimensional outline, but you still need to color and define the features with frosting. The XIYUAN gives you the fish shape to start from; the Hyoocct is a simpler 9-inch fish-pan alternative. If you don’t enjoy piping, bake a sheet cake and use an edible image topper instead—the Hyoocct or XIYUAN is for when the molded silhouette is part of the fun.
Will a boxed mix work?
A boxed mix is a practical starting point for all three pans; follow its directions and avoid filling a novelty shape right to the rim. Thin fins or tails can bake faster than the thicker middle, so check doneness in the deepest part and keep an eye on the edges. For the least stressful first attempt, choose the GXHUANG for flexible release or use a sheet cake with a topper.

Questions buyers ask
Is an edible image topper easier than a shaped cake pan for beginners?
Usually, yes. A sheet cake is simpler to bake, level, frost, and transport, and the image does most of the character decorating. A shaped pan makes a more dimensional cake, but it needs careful release and some extra frosting work.
Can I use an edible image cake topper instead?
Yes. Put the image on a fully cooled, frosted cake and follow the topper’s handling instructions. It’s a good choice when you want a recognizable character design without having to pipe the details yourself.
What’s the easiest way to make a DIY ocean-themed birthday cake?
Bake a sheet cake, frost it in a sea-inspired color, then add an edible image or simple fish-shaped decorations. If you want the cake itself to have a fish outline, use the XIYUAN or Hyoocct pan and keep the frosting details simple.
How do I keep a shaped cake from sticking?
Work baking spray with flour into narrow grooves and corners before adding batter; it is easier to coat those details before the pan is filled.
How can I prevent thin parts from overbaking before the center is done?
If narrow parts brown early, loosely shield them while the middle finishes. Avoid overfilling the pan, which can make baking less even.
Is a sheet cake with an edible image better than a molded cake?
Choose a sheet cake when predictable baking and quick character decoration matter most; choose one of these fish pans only if an ocean-themed 3D silhouette matters more than an exact Bubble Guppies likeness.
