Ingredients

  • Cake Flour
  • Granulated Sugar
  • Baking Powder
  • Salt
  • Buttermilk
  • Eggs
  • Vanilla Bean Paste or Fresh Vanilla Bean
  • Vegetable Oil
  • Gel Food Coloring
  • Unsalted Butter
  • Powdered Sugar (Confectioners' Sugar)
  • Heavy Cream or Milk (for Buttercream)
  • Optional Floral Flavoring (for Buttercream)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour five 6-inch round cake pans or three 8-inch round cake pans. Line the bottoms with parchment paper circles.
  2. In a large bowl, whisk together the cake flour, granulated sugar, baking powder, and salt.
  3. In a separate medium bowl, whisk together the buttermilk, eggs, vanilla bean paste (or scraped vanilla bean seeds), and vegetable oil.
  4. Add the wet ingredients to the dry ingredients. With an electric mixer on low speed, mix until just combined and no streaks of flour remain. Be careful not to overmix!
  5. Divide the cake batter evenly into 5 (or 3, depending on your pan choice) separate bowls. Gradually add a tiny amount of a different gel food coloring to each bowl, stirring gently until you achieve your desired pastel shade.
  6. Pour each colored batter into its prepared pan. Bake for 20-25 minutes for 6-inch pans, or 25-30 minutes for 8-inch pans, or until a wooden skewer inserted into the center comes out clean.
  7. Let the cakes cool in the pans for 10-15 minutes before inverting them onto a wire rack to cool completely.
  8. In a large bowl with an electric mixer, beat the room temperature unsalted butter on medium speed for 5-7 minutes, until it's very light, pale, and fluffy.
  9. Gradually add the sifted powdered sugar, one cup at a time, mixing on low speed until combined, then increasing to medium-high.
  10. Once all the sugar is incorporated, beat in the vanilla extract. Slowly add the heavy cream or milk, a tablespoon at a time, until the buttercream reaches your desired consistency.
  11. Divide a small amount of buttercream into separate bowls and tint with gel food coloring to create specific colors for your floral designs.
  12. Once completely cool, use a serrated knife or cake leveler to level any domed tops from your cake layers.
  13. Place the darkest ombre cake layer on your serving plate or cake stand. Spread a thin layer of white/neutral buttercream over the top. Stack the next darkest layer, repeating until all layers are stacked, ending with the lightest ombre layer on top.
  14. Apply a very thin, even layer of buttercream all over the cake (top and sides). Chill the cake in the refrigerator for at least 30 minutes, or until the crumb coat is firm.
  15. Once the crumb coat is firm, apply a generous, even layer of the remaining white/neutral buttercream to the top and sides of the cake. Chill again for 15-20 minutes to set.
  16. Using various piping tips and your colored buttercreams, pipe an assortment of flowers and leaves directly onto the chilled cake.
