🧁 Ingredients

Vanilla Sponge Cake (for each tier – triple for 3 tiers):

• 2½ cups all-purpose flour (or cake flour for a lighter crumb)

• 2½ tsp baking powder

• ½ tsp salt

• 1 cup unsalted butter, room temperature (or coconut oil for tropical flavor)

• 2 cups granulated sugar

• 4 large eggs

• 1 tbsp vanilla extract

• 1 cup whole milk (or coconut milk for more island flair)

Coconut Buttercream:

• 1½ cups unsalted butter, room temperature

• 5 cups powdered sugar, sifted

• ¼ cup coconut milk

• 1½ tsp coconut extract (optional: add vanilla or lime zest)

• Pinch of salt

Beach Sand (edible):

• 1 cup crushed graham crackers or brown sugar

• ½ cup finely ground vanilla wafer cookies (optional)

Fondant Decorations:

• White and pastel-colored fondant

• Gel food coloring (blue, teal, sand, tan)

• Small fondant molds: shells, starfish, palm trees

🌴 Ingredient Alternatives

• Flour: Gluten-free blend (1:1 ratio)

• Dairy-Free: Use vegan butter and plant-based milk

• Buttercream Flavor: Swap coconut for lemon, pineapple, or mango for a tropical twist

• Fondant-Free Option: Use modeling chocolate or pre-made candy seashells

Step 1: Bake the Cake Layers

Preheat oven to 350°F (175°C). Grease and line cake pans.

Whisk flour, baking powder, and salt in a bowl.

In a separate bowl, cream butter and sugar until fluffy (3–4 min).

Add eggs one at a time, then vanilla.

Alternate adding flour mixture and milk until smooth.

Divide evenly between pans and bake 25–35 minutes (adjust by size).

Cool completely before leveling and stacking.

Tip Alert: Use cake dowels and boards between tiers for structure & freeze cake layers before stacking for easier handling

Step 2: Make the Coconut Buttercream

Beat butter until pale and fluffy.

Gradually add powdered sugar, beating in coconut milk and extract.

Whip until smooth and spreadable.

 Step 3: Assemble and Decorate

Level cakes and stack each tier with buttercream between layers.

Crumb coat each tier and chill for 30 minutes.

Apply final coat of ombré buttercream (light blue to teal gradient).

Press graham “sand” around each tier and on top.

Use fondant to craft seashells, starfish, and palm trees. Place them strategically.

Tip Alert: For smooth fondant shells, dust molds lightly with cornstarch. Use an offset spatula and bench scraper for cleaner frosting edges. Also mix brown sugar and graham crumbs for more realistic sand texture.
