# Step-by-Step Guide:
01 - Preheat oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - In a medium bowl, sift together flour, baking powder, and salt. Set aside.
03 - In a large bowl, cream butter and sugar together until light and fluffy, approximately 3 to 4 minutes.
04 - Beat in eggs one at a time, then add vanilla extract.
05 - Add flour mixture in three additions, alternating with milk, beginning and ending with flour. Mix until just combined.
06 - Divide batter evenly among prepared pans and smooth tops with a spatula.
07 - Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.
08 - Cool cakes in pans for 10 minutes, then transfer to a wire rack to cool completely.
09 - Beat butter until creamy. Gradually add powdered sugar, mixing well after each addition. Add vanilla and salt, then beat in milk a little at a time until frosting is smooth and spreadable.
10 - Divide frosting into four bowls. Tint each with blue gel food coloring, creating a gradient from pale to deep ocean blue.
11 - Place one cake layer on a serving plate. Spread with a thin layer of the lightest blue frosting. Repeat with remaining layers.
12 - Using an offset spatula, frost the sides and top of the cake, starting with the lightest shade at the top and gradually working down to the deepest blue at the base, blending where colors meet.
13 - Decorate with white chocolate seashells, edible glitter, and sprinkles as desired.
14 - Chill cake for 30 minutes before slicing for optimal results.
