A stunning Purple Ombre Cake featuring layered vanilla sponge tinted in gradually deepening shades of purple, filled and frosted with silky buttercream for an elegant gradient effect.

Ingredients

Scale
  • 2 1/2 cups all-purpose flour
  • 2 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1 cup unsalted butter, softened
  • 1 3/4 cups granulated sugar
  • 4 large eggs, room temperature
  • 1 tbsp vanilla extract
  • 1 cup whole milk, room temperature
  • Purple gel food coloring (various intensities)
  • 2 cups unsalted butter (for frosting), softened
  • 5 cups powdered sugar
  • 1/4 cup heavy cream
  • 1 tbsp vanilla extract (for frosting)
  • Pinch of salt

Instructions

  1. Preheat the oven to 350°F (175°C). Grease and line four 6-inch or three 8-inch round cake pans.
  2. In a bowl, whisk together the flour, baking powder, and salt.
  3. In another bowl, cream butter and sugar until light and fluffy. Add eggs one at a time, then mix in vanilla extract.
  4. Alternate adding dry ingredients and milk to the butter mixture until fully combined.
  5. Divide the batter evenly into 3–4 bowls and tint each with increasing amounts of purple food coloring to create an ombre effect.
  6. Pour the batters into prepared pans and bake for 20–25 minutes, or until a toothpick comes out clean.
  7. Let cakes cool completely before assembling.
  8. For the frosting: Beat butter until creamy, then gradually add powdered sugar. Add vanilla, cream, and salt, beating until smooth.
  9. Level cake layers if needed. Stack layers from lightest to darkest, spreading frosting between each.
  10. Apply a light crumb coat and chill 20 minutes. Finish with a smooth layer of frosting, blending darker purple at the base for an ombre exterior.

Notes

  • Use gel food coloring for stronger pigmentation without thinning the batter.
  • Chill the cake layers before decorating for easier handling.
  • You can add purple sprinkles, edible glitter, or flowers for garnish.
