Instructions:

1. Prepare the cake batter:

   • Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans.

   • In a bowl, whisk together flour, baking powder, and salt.

   • In a large mixing bowl, beat butter and sugar until light and fluffy (about 3–4 minutes).

   • Add eggs one at a time, mixing well after each addition. Stir in vanilla.

   • Alternate adding dry ingredients and milk, beginning and ending with dry ingredients.

2. Color & bake:

   • Divide batter into three portions. Keep one plain, color one pink, and one blue.

   • Pour each into a separate cake pan. Bake for 20–25 minutes or until a toothpick comes out clean.

   • Cool completely before frosting.

3. Make the buttercream frosting:

   • Beat butter until creamy. Gradually add powdered sugar, alternating with cream.

   • Beat in vanilla extract. Divide into three portions and tint one pink, one blue, leaving one white.

4. Assemble the cake:

   • Place blue cake layer on a serving plate, spread blue frosting on top.

   • Add white cake layer, spread white frosting.

   • Add pink cake layer, spread pink frosting all over cake for crumb coat. Chill for 30 minutes.

5. Decorate:

   • Apply final frosting layers in ombre effect (blue bottom, white middle, pink top).

   • Melt white chocolate or candy melts, drizzle along the edges for the drip effect.

   • Top with cotton candy just before serving and sprinkle with colorful sprinkles.

✨ Tip: Add the cotton candy right before serving so it stays fluffy and doesn’t melt from the frosting.
