Instructions
Step 1: Bake the Cake Layers
1. Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.
2. In a medium bowl, whisk together flour, baking powder, and salt.
3. In a large bowl, cream butter and sugar with an electric mixer until light and fluffy (3–4 minutes).
4. Beat in eggs one at a time, then add vanilla.
5. Mix in dry ingredients in three parts, alternating with milk, beginning and ending with dry ingredients.
6. Divide batter evenly between pans and smooth tops.
7. Bake 25–30 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool in pans for 10 minutes, then turn out onto wire racks to cool completely.

Step 2: Make the Buttercream
1. Beat butter until smooth and creamy (about 3 minutes).
2. Gradually add powdered sugar, mixing on low until combined.
3. Add vanilla and 2 tbsp cream; beat on high for 3–4 minutes until fluffy, adding more cream if needed.
4. Divide frosting into three bowls:
White: leave one portion uncolored.
Sky Blue: mix in a few drops of sky blue gel.
Navy Blue: mix sky blue and a small amount of navy blue gel.

Step 4: Create the Ocean Waves
1. With an offset spatula, dab alternating colors of buttercream (white, light blue, dark blue) randomly over the cake.
2. Gently blend by swiping horizontally to create a marbled ocean effect—avoid overmixing so the colors stay distinct.
3. For wave peaks, apply extra white frosting along the top edges and swirl upward with a spatula or spoon.

Step 5: Add the Sandy Beach
1. Mix graham cracker crumbs with brown sugar for a realistic sandy look.
2. Press the mixture around the base of the cake or on one side of the top to resemble a shoreline.
3. Optionally, add small edible seashells or starfish made from fondant or molded chocolate.
