Ingredients

  • All-purpose flour: The base for this cake, giving it the perfect structure and texture.

Prepare the oven and pans:
Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans to ensure the cake releases beautifully after baking.
Mix the dry ingredients:
In a bowl, whisk together the flour, baking powder, and salt, setting this mixture aside for later use.
Cream the butter and sugar:
In a large bowl, cream together the softened butter and granulated sugar until the mixture turns light and fluffy, this should take about 4-5 minutes.
Add the eggs and flavors:
Add the eggs one by one, beating well after each addition, and stir in the vanilla extract to infuse sweetness.
Combine dry and wet mixes:
Alternate adding the flour mixture and milk to the wet ingredients, starting and ending with flour; be careful to mix just until all is combined to avoid a dense cake.
Bake the layers:
Divide the batter evenly between the prepared pans, smoothing the tops, and bake for 30-35 minutes or until a toothpick inserted comes out clean.
Cool the cake:
Let the cakes cool in the pans for 10 minutes before turning them out onto wire racks to cool completely.
Make the buttercream:
Beat softened butter until creamy before gradually adding the powdered sugar, mixing well, then incorporate the vanilla and heavy cream until fluffy.
Layer the cake:
Level off the cakes if necessary, place one layer on a serving plate, spread on buttercream, and stack the second layer before chilling for a crumb coat.
Final buttercream finish:
Cover the cake with a thick layer of blue buttercream and texture it to resemble ocean waves for a striking effect.
Make chocolate shells:
Melt the white chocolate chips in a microwave-safe bowl and pour them into shell molds, then chill until set and gently unmold.
Decorate:
Arrange your edible shells artistically on and around the cake, and add glitter for that ocean sparkle.
Chill and serve:
Allow the cake to chill until ready to serve, enhancing its flavors beautifully.
