Ingredients

  • All-purpose flour – 2 ½ cups (315 g), sifted
  • Baking powder – 2 ½ teaspoons (10 g)
  • Salt – ½ teaspoon (3 g)
  • Unsalted butter – 1 cup (227 g), softened (for cake)
  • 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)
  • Yellow gel food coloring – 1 teaspoon
  • Unsalted butter – 1 cup (227 g), softened (for buttercream)
  • Powdered sugar – 4 cups (480 g), sifted
  • Heavy cream – 2–3 tablespoons (30–45 ml)
  • Pure vanilla extract – 1 teaspoon (5 ml)
  • Blue gel food coloring – 1 teaspoon
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, mixing well after each addition.
  5. Mix in milk and vanilla extract until smooth.
  6. Stir in yellow gel food coloring, adjusting for desired color.
  7. Slowly add dry ingredients to wet ingredients, mixing on low speed just until combined.
  8. Divide batter evenly between prepared pans and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
  9. Cool cakes in pans for 10 minutes, then transfer to wire racks to cool completely.
  10. For the blue buttercream, beat softened butter until creamy.
  11. Gradually add powdered sugar, alternating with heavy cream, until smooth and fluffy.
  12. Mix in vanilla extract, salt, and blue gel food coloring gradually until desired shade is reached.
  13. Beat buttercream for an additional 3 minutes for fluffiness.
  14. Place one yellow cake layer on serving plate and spread about ¾ cup of blue buttercream evenly on top.
  15. Place second cake layer over and frost top and sides with remaining buttercream using an offset spatula.
  16. Smooth sides with a bench scraper or create soft swirls on top.
  17. Chill cake for 30 minutes before slicing to set the buttercream.

Notes

Use gel food coloring for vibrant colors without thinning batter or frosting. Keep buttercream chilled but spreadable; if too soft, refrigerate briefly. Room temperature ingredients ensure smooth batter and better rise. Overmixing flour can make cake dense. For dairy-free option, substitute butter with coconut oil and heavy cream with full-fat coconut milk.
