Instructions
Preheat oven to 350°F. Spray three 6-inch round cake pans with nonstick spray and lightly dust with flour.
Mix cake ingredients in a large bowl until smooth.
Divide evenly into pans and bake for 30 minutes or until a toothpick inserted comes out clean.
Cool for 15–20 minutes, then remove from pans and let cool completely.
For frosting, beat butter until fluffy. Gradually add powdered sugar, then mix in vanilla, salt, and cream.
Tint small amounts of frosting in separate bowls with food coloring.
Frost the cake with white buttercream. Use a skinny spatula to apply petals, leaves, and flower centers in colored buttercream.
