03 - ½ teaspoon salt
04 - 1 cup unsalted butter, room temperature
05 - 1¾ cups granulated sugar
06 - 4 large eggs, room temperature
07 - 1 tablespoon pure vanilla extract
08 - 1 cup whole milk, room temperature

→ Buttercream Frosting

09 - 1½ cups unsalted butter, room temperature
10 - 5 cups powdered sugar, sifted
11 - 2 teaspoons pure vanilla extract
12 - ¼ cup whole milk, room temperature
13 - Blue gel food coloring in various shades

15 - Edible pearls or sugar pearls, optional

# Method:

01 - Preheat oven to 350°F. Grease and line a 9x13-inch sheet cake pan with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt until evenly distributed.
03 - In a large bowl, beat butter and sugar until light and fluffy, approximately 3 minutes, scraping bowl sides as needed.
04 - Add eggs one at a time, mixing well after each addition. Beat in vanilla extract until fully combined.
05 - Alternately add flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined to avoid overmixing.
06 - Pour batter into prepared pan and smooth the top. Bake for 28 to 32 minutes, or until a toothpick inserted in the center comes out clean.
07 - Cool cake in pan for 10 minutes, then transfer to a wire rack to cool completely before frosting.
08 - Beat butter on medium speed until creamy, about 2 minutes. Gradually add powdered sugar on low speed. Add vanilla and milk; beat until fluffy and smooth.
09 - Divide buttercream into 3 to 4 bowls. Tint each with varying shades of blue ranging from deep ocean blue to pale aqua, leaving one portion white.
10 - Once cake is completely cool, spread a thin layer of white buttercream over the entire cake as a crumb coat. Chill for 20 minutes.
11 - With an offset spatula, layer blue buttercreams in wave-like shapes across the cake, starting with the darkest shade at the base and working up to the lightest. Use swooping motions to mimic ocean waves.
12 - Pipe or swirl white buttercream on top to create sea foam effect.
13 - Optionally decorate with edible pearls and add a Pisces symbol made from white chocolate or fondant.
