# How to Make It:

01 - Preheat oven to 350°F. Grease and line four 8-inch round cake pans 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 3-4 minutes.
04 - Add eggs one at a time to the butter mixture, mixing well after each addition. Blend in vanilla extract.
05 - Alternately add flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined.
06 - Divide batter evenly into four bowls. Tint each bowl with increasing amounts of gel food coloring to achieve a gradient ombre effect.
07 - Pour each colored batter into prepared pans and smooth the tops. Bake for 22-25 minutes, or until a toothpick inserted in the center comes out clean.
08 - Let cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
09 - Combine egg whites and sugar in a heatproof bowl over a pot of simmering water. Whisk constantly until sugar dissolves and temperature reaches 160°F, approximately 8-10 minutes.
10 - Transfer mixture to a stand mixer and whip on high speed until stiff peaks form and the mixture cools completely, approximately 10 minutes.
11 - Gradually add softened butter cubes, a few at a time, mixing well between additions. Add vanilla extract. Tint portions with gel food coloring if desired.
12 - Trim cake layers if necessary. Place the darkest layer on a cake stand, spread with buttercream, and repeat with remaining layers, progressing from darkest to lightest.
13 - Apply a thin crumb coat of buttercream over the entire cake surface. Chill for 20 minutes.
14 - Frost with a final layer of buttercream, blending colors for an ombre effect. Decorate with edible pearls, toppers, or piped details as desired.
15 - Chill cake until buttercream is set. Bring to room temperature for 30 minutes before serving.

# Expert Advice:

01 -
  • It looks like you spent all day on it, but the technique is genuinely manageable once you understand the rhythm.
  • Swiss meringue buttercream stays silky and doesn't break, even if your kitchen is warm or you're nervous.
  • Four layers mean you can customize each one with different colors, making it feel personal to whoever you're celebrating.
02 -
  • Swiss meringue buttercream can look broken and separated when you first add the butter, but continuous mixing will bring it back to silky smoothness; don't panic and throw it away.
  • The difference between a dry cake and a moist one is often just the alternating wet and dry ingredients—skipping this step and adding everything together will betray you.
  • Gel food coloring needs to be fully incorporated, so add it, let the mixer run for an extra minute, and stir by hand to make sure there are no streaks before dividing into pans.
03 -
  • If your gel coloring is very concentrated, add it to the batter with a toothpick—a tiny amount goes a long way and prevents unintended dark spots.
  • A bench scraper is more useful than a spatula for smoothing the sides of a frosted cake; it gives you clean lines and better control.
  • Make the buttercream the day before and store it at room temperature in an airtight container; it stays spreadable and tastes better than cold frosting straight from the fridge.
