Ingredients

Scale
  • 2 ½ cups (320g) all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • 1 cup (226g) unsalted butter, softened
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 1 cup (240ml) buttermilk, room temperature
  • 2 tsp pure vanilla extract
  • 1 tsp almond extract (optional)
  • ½ cup cooked and mashed purple sweet potato or ½ cup blueberry puree (for the purple layer)
  • 1 tbsp matcha powder or ½ cup pureed fresh spinach (for the green layer)
  • ¼ tsp turmeric powder or 2 tbsp saffron-infused milk (for the golden layer)
  • 1 cup (230g) unsalted butter, softened (for frosting)
  • 4 cups (480g) powdered sugar, sifted
  • 24 tbsp whole milk or cream (for frosting)
  • 1 tsp vanilla extract (for frosting)
  • Pinch of salt (for frosting)

Instructions

  1. Preheat oven to 350°F (175°C). Grease three 8-inch cake pans and line bottoms with parchment paper.
  2. In a medium bowl, sift together flour, baking powder, baking soda, and salt. Whisk to combine.
  3. In a large bowl, beat softened butter and granulated sugar on medium-high speed until pale and fluffy, about 4 minutes.
  4. Add eggs one at a time, beating well after each addition. Mix in vanilla and almond extracts.
  5. Reduce mixer speed to low. Alternately add dry ingredients and buttermilk in three additions, starting and ending with dry ingredients. Mix just until combined.
  6. Divide batter evenly into three bowls. Gently fold purple sweet potato or blueberry puree into one, matcha powder or spinach puree into second, turmeric or saffron milk into third.
  7. Pour each colored batter evenly into prepared pans. Bake 25-30 minutes or until toothpick inserted comes out clean.
  8. Cool cakes in pans for 10 minutes, then invert onto cooling racks. Remove parchment and cool completely.
  9. For frosting, beat softened butter until creamy. Gradually add powdered sugar alternating with milk or cream until smooth. Stir in vanilla and salt.
  10. Assemble cake by layering purple, green, and gold layers with frosting between each. Frost top and sides. Chill 30 minutes to set if desired.

Notes

Use room temperature ingredients for best results. Fold in colors gently to keep batter light and airy. Chill cake before frosting for clean layers. If frosting is too soft, refrigerate 15 minutes; if too stiff, add milk. Can bake layers one at a time if only one pan is available.
