# Directions:
01 - Preheat oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - Sift together flour, baking powder, and salt in a medium bowl. Set aside.
03 - In a large bowl, cream softened butter and sugar together until light and fluffy, approximately 3-4 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 25-30 minutes 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 softened butter until creamy. Gradually add powdered sugar, mixing well after each addition. Add vanilla and salt. Beat in milk progressively until frosting reaches smooth, spreadable consistency.
10 - Divide frosting into 4 bowls. Tint each with blue gel food coloring, creating a gradient progression from pale to deep ocean blue.
11 - Place first cake layer on serving plate. Spread with thin layer of lightest blue frosting. Repeat with remaining layers.
12 - Using an offset spatula, frost sides and top of cake, starting with lightest shade at top and gradually transitioning to deepest blue at base, blending where colors meet for seamless ombre effect.
13 - Embellish with white chocolate seashells, edible glitter, and blue and silver sprinkles as desired.
14 - Refrigerate cake for 30 minutes before slicing for optimal texture and presentation.
