# How To Make It:

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.
03 - In a large bowl, beat butter and sugar until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, mixing well after each addition. Beat in vanilla extract.
05 - Alternately add flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined.
06 - Pour batter into prepared pan and smooth the top. Bake for 28-32 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.
08 - Beat butter on medium speed until creamy, about 2 minutes. Gradually add powdered sugar, mixing on low speed. Add vanilla and milk; beat until fluffy and smooth.
09 - Divide buttercream into 3-4 bowls. Tint each with varying shades of blue (from deep ocean blue to pale aqua) and leave 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 - Decorate with edible pearls and add a Pisces symbol made from white chocolate or fondant if desired.

# Expert Advice:

01 -
  • The vanilla sponge is impossibly moist and stays tender for days, which means you can actually bake it ahead without stress.
  • Blue ombré frosting looks like you spent hours at cake decorating school when really it's just swooping motions and letting the colors blend naturally.
  • It's forgiving enough for a home baker but impressive enough to make people think you're secretly a pastry chef.
02 -
  • Gel food coloring is your secret weapon because liquid coloring will thin your buttercream and make it impossible to pipe or hold its shape.
  • Chilling between decorating steps genuinely matters—it keeps frosting from slipping and gives you clean, defined wave lines instead of muddy color blending.
03 -
  • If you're nervous about the piping, practice your waves on a plate with extra frosting first—your hands will remember the motion by the time you get to the cake.
  • Offset spatulas are worth the few dollars they cost because they let you spread frosting smoothly without your hand getting in the way.
