We have all been there—the birthday request comes in, and suddenly you are panic-scrolling for ideas that will not take three days to construct. I love baking, but I also love my sanity, especially when planning a party. That is why I am obsessed with this cake; it looks like a professional masterpiece, but it is really just a clever assembly job that comes together in an afternoon.
This Moana-inspired cake is my secret weapon for easy entertaining. It uses simple vanilla layers, a quick ‘dirty icing’ trick, and crushed biscuits to create a stunning sandy beach effect without any fondant fuss. It is sweet, impressive, and surprisingly simple to pull off right in your own kitchen.
Why This Recipe is a Real Lifesaver
Let’s be honest, character cakes can be intimidating, but this one is all about smart shortcuts. You don’t need to be a sculptor to make this look amazing; the ‘ocean’ is just swirled buttercream and the ‘sand’ is crushed cookies. It brings that island vibe to the table with honest flavors—buttermilk vanilla cake and strawberry jam—that kids and adults actually want to eat.

Description
Create a magical tropical celebration with this easy-to-assemble Moana cake featuring edible biscuit sand and blue buttercream waves. It is a stress-free way to make a professional-looking character cake that kids will absolutely adore.
Ingredients
- 3 layers of vanilla cake
- 3 to 4 batches of buttercream icing
- 1 cup strawberry jam
- 1 cup crushed biscuits (Granita, digestives, or graham crackers)
- Blue food coloring
- Moana-themed cake toppers and toy sea animals
- Chocolate fingers
- Piping bag
Instructions
- Secure the first cake layer to a large tray or cake board using five small blobs of buttercream as glue.
- Spread a layer of strawberry jam over the first layer, leaving a 1cm border, then top with a layer of buttercream.
- Repeat the process with the second cake layer and place the third cake layer on top.
- Apply a thin crumb coat of white buttercream over the top and sides, then refrigerate for 30 minutes to set.
- Mix blue food coloring into two-thirds of the remaining buttercream and spread it in a wavy pattern for the ocean, leaving a white space for the beach.
- Press crushed biscuits into the white icing area to create sand and finish by adding toppers and chocolate finger decorations.
Notes
Ensure your cake layers are completely chilled before starting the assembly process to prevent them from sliding. If you do not have a piping bag, a zip-top bag with a corner snipped off works perfectly for filling the layers and creating the ocean waves.

Simple Ingredients for Island Vibes
I keep things accessible because nobody wants to hunt for obscure ingredients on a Tuesday. Here is what you need to build this tropical beauty:
- Cake Layers: You will need 3 layers of vanilla cake. I use a simple buttermilk recipe, but honestly, you can use your favorite box mix or even store-bought sponge layers if you are pressed for time.
- Buttercream Icing: You need plenty of this—about 3 to 4 batches—to fill, coat, and decorate the waves.
- Strawberry Jam: This adds a sweet, fruity surprise between the layers.
- The ‘Sand’: Granita biscuits, digestives, or graham crackers work perfectly when crushed.
- The ‘Ocean’: Blue food coloring is essential for that wave effect.
- Decorations: Moana cake toppers, toy sea animals, chocolate fingers (great for a raft or border), and a clean piping bag.
How to Make It
Step 1: Build the Foundation
Start by securing your cake to the board. Place five small blobs of buttercream on your large tray or cake board—one in each corner and one in the center. This acts as ‘glue’ to keep everything steady. Place your first cake layer down right on top.
Step 2: Stack and Fill
Spread a generous layer of strawberry jam over the first cake layer, leaving a 1cm border at the edge so it doesn’t leak out. Next, pipe or spread a layer of buttercream over the jam, keeping that same border. Place the second cake layer on top and repeat the jam and buttercream process. Top it with the third and final cake layer.
Step 3: The Crumb Coat
Now for the ‘dirty icing.’ Using a palette knife, spread a thin layer of white buttercream over the top and sides of the cake. This seals in the crumbs so your final layer looks clean. Pop the whole cake in the fridge for about 30 minutes to set.
Step 4: Create the Ocean and Beach
Take about two-thirds of your remaining buttercream and mix in a few drops of blue food coloring until you have a nice ocean hue. Spread this over the top and sides to create a wave effect—don’t worry about being perfect; waves are messy! Leave some space for the ‘beach’ area using the plain white icing.
Step 5: Final Touches
Press the crushed biscuits into the white icing area to create the sand. Position your Moana toppers and secure them with a little extra icing at the base. Add your chocolate fingers or shells for extra flair, and you are done!
Meagan’s Tips for Success
- Chill Your Cake: Working with cold cake layers makes stacking so much easier. If your layers are too soft, they might slide around while you frost.
- No Piping Bag? If you don’t have a fancy piping bag for the filling, just use a zip-top bag with the corner snipped off. It works just as well.
- Plan Ahead: You can bake the cake layers a day in advance and wrap them tightly in plastic wrap. This actually helps the texture settle.
- Party Planning: If you are tackling a huge celebration, check out our guide on party cakes and events for more timeline tips.
Make It Your Own
- Flavor Swaps: Not a fan of strawberry jam? Lemon curd makes for a zesty, tropical twist that pairs beautifully with vanilla.
- Different Themes: You can use this same ‘sand and sea’ technique for other themes. It works great as a base for a pirate party or even a Roblox cake if you change the toppers.
- Chocolate Lovers: Swap the vanilla cake for chocolate layers and use cocoa powder in the ‘sand’ mixture for a volcanic island look.
How to Serve
This cake is a showstopper, so I like to bring it out whole before slicing. Serve generous squares with a glass of cold milk for the kids and maybe a coffee for the adults. If you are hosting a joint party or need another easy vehicle for candles, this pairs really well alongside our fun car cake for a mix of themes.
