# How To Make It:

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. Beat in milk, a little at a time, until frosting is smooth and spreadable.
10 - Divide frosting into 4 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 for an ombre effect.
13 - Decorate with white chocolate seashells, edible glitter, and sprinkles as desired.
14 - Chill cake for 30 minutes before slicing for best results.

# Expert Suggestions:

01 -
  • The vanilla sponge stays impossibly moist and tender, even days later if you brush it with simple syrup.
  • Creating the ombre frosting is genuinely fun—watching the colors blend feels like edible art that tastes even better than it looks.
  • It's the kind of cake that makes people pause mid-conversation to ask how you made it.
02 -
  • Room temperature ingredients are not optional—they blend together smoothly and create a superior crumb and frosting texture that cold ingredients simply cannot match.
  • Gel food coloring changed my entire frosting game; liquid coloring thins out your frosting and muddies the colors, but gel gives you vibrant, rich shades that stay perfectly spreadable.
03 -
  • If your frosting seems too stiff, add milk one teaspoon at a time; if it's too soft, pop it in the fridge for five minutes to firm up slightly before continuing.
  • The secret to a smooth ombre is blending your colors where they meet—use a clean offset spatula to gently feather one shade into the next, creating transitions that feel natural and effortless.
