# How-To Steps:

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.
04 - Add eggs one at a time, mixing well after each addition. Mix in vanilla extract.
05 - Alternate adding 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.
08 - Bake for 22 to 25 minutes, or until a toothpick inserted in the center comes out clean. Let cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
09 - For the buttercream, combine egg whites and sugar in a heatproof bowl over a pot of simmering water. Whisk constantly until sugar dissolves, approximately 160°F.
10 - Transfer to a mixer and whip on high until stiff peaks form and the mixture is cool, about 10 minutes.
11 - Gradually add butter, a few cubes at a time, mixing well. Add vanilla extract. If desired, tint portions with gel food coloring to create ombre or accent piping.
12 - Trim cake layers if necessary. Place the darkest layer on a cake stand, spread with buttercream, and repeat with remaining layers, from darkest to lightest.
13 - Apply a thin crumb coat of buttercream over the entire cake and chill for 20 minutes.
14 - Frost with a final layer of buttercream, blending colors for an ombre effect if desired. Decorate with pearls, toppers, or piped details.
15 - Chill until set; bring to room temperature before serving.

# Expert Tips:

01 -
  • The ombre effect looks impossibly fancy but is actually forgiving once you understand the coloring trick.
  • Swiss meringue buttercream is silkier than American buttercream and holds those beautiful color gradients without looking streaky or dull.
  • You'll feel like a pastry chef when you pull this out of the kitchen, even though the hardest part is just patience with the cooling.
02 -
  • Room temperature ingredients aren't a suggestion—they're the difference between silky buttercream and grainy, broken frosting that looks curdled.
  • Gel food coloring changes the game for ombre cakes because you use so little that it doesn't dilute your batter the way liquid coloring would.
  • If your Swiss meringue buttercream breaks and looks like scrambled eggs, don't panic; keep mixing on high speed and it will usually come back together within a minute or two.
03 -
  • If you don't have four cake pans, you can bake two layers, let them cool, then divide each layer horizontally with a serrated knife and a cake leveler to create four layers—it takes more time but works beautifully.
  • Chill your cake layers before frosting them; cold cake is more stable and less likely to shift or crumble as you build your layers upward.
  • The night before serving, loosely cover the finished cake and refrigerate it; this sets the buttercream and makes slicing cleaner, and you can bring it to room temperature while you set the table.
