Ingredients

  • All-purpose flour, 2 ¾ cups (345 g), sifted
  • Baking powder, 2 ½ teaspoons (12 g)
  • Salt, ½ teaspoon (3 g)
  • Unsalted butter, 1 cup (227 g), softened
  • Granulated sugar, 1 ¾ cups (350 g)
  • Large eggs, 4, room temperature
  • Whole milk, 1 cup (240 ml), room temperature
  • Pure vanilla extract, 2 teaspoons (10 ml)
  • Unsalted butter, 1 cup (227 g), softened (for buttercream)
  • Powdered sugar, 4 cups (480 g), sifted
  • Whole milk or heavy cream, 2 to 3 tablespoons (30-45 ml)
  • Pure vanilla extract, 1 teaspoon (5 ml)
  • Gel food coloring in pastel tones (pink, lavender, soft green)
  • Fresh edible flowers (such as pansies, violets, or rose petals)
  • Optional: fresh berries for garnish

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 8-inch round cake pans and line bottoms with parchment paper.
  2. In a medium bowl, whisk together sifted all-purpose flour, baking powder, and salt. Set aside.
  3. Using a mixer, beat softened butter and granulated sugar on medium speed for 3 to 5 minutes until pale and fluffy.
  4. Add eggs one at a time, beating well after each addition and scraping down bowl sides.
  5. Alternate adding dry ingredients and milk to butter mixture, beginning and ending with dry ingredients. Mix on low speed until just combined.
  6. Add vanilla extract and mix briefly.
  7. Divide batter evenly between pans (about 3 cups or 720 ml each). Bake for 30 to 35 minutes or until a toothpick inserted in center comes out clean.
  8. Cool cakes in pans for 10 minutes, then turn out onto cooling racks to cool completely.
  9. For buttercream, beat softened butter on medium speed until creamy, about 2 minutes. Gradually add powdered sugar alternating with milk or cream until smooth and fluffy. Stir in vanilla extract.
  10. Divide buttercream into small bowls and tint each with gel food coloring. Use a clean paintbrush to apply dabs of color randomly on the cake’s crumb coat.
  11. Spread a thin, smooth layer of plain buttercream over entire cake to seal crumbs. Chill for 20 minutes to set.
  12. Using an offset spatula or bench scraper, gently smooth colored buttercream dabs, blending colors softly to create watercolor effect. Repeat until desired look is achieved.
  13. Decorate cake with fresh edible flowers, arranging naturally. Rinse and dry flowers gently before use.
  14. Chill cake for at least 30 minutes before serving. Bring to room temperature 15 minutes before slicing.

Notes

Use softened but not melting butter for best buttercream texture. Apply gel food coloring sparingly and blend gently for watercolor effect. Use only fresh edible flowers or food-safe artificial flowers with a barrier. Chill cake before decorating and serving to prevent melting. For vegan or gluten-free versions, substitute ingredients accordingly and monitor batter texture.
