Start with a basic vanilla cake recipe your own or a box(using directions on box or your own recipe)
Divide d the batter as evenly as possible between 5 bowls, coloring the darkest layer first, and working from the darkest color as a guide.
Add the batter to prepared cake pans (greased and floured, and lined on the bottom with parchment paper
use a buttercream frosting and dived that into 4 bowls add a little more to the lightest color since that will be for the top of the cake too
Save some for in between the layers you can color or leave as plain buttercream
Bake cakes according to box or your own recipe
when done and cooled
Layer the cakes, darkest on the bottom, frost with a very thin layer of icing between each layer. . Frost the outside of the cake with a thin layer of frosting. Smooth as well as you can Place the entire cake in the freezer about 10 minutes for the icing to set, and the whole cake will firm up (making it much easier to decorate).
Prepare a piping bag with a #21 Wilton tip (a moderate sized open star) Fill piping bag with the darkest color icing.
Remove cake from freezer, and start along the bottom of the cake, creating rows of swirls. For each swirl, start in the center of the ”rose” shape and pipe in a spiral around the center, about 1 1/2 rotations. Continue along the bottom of the cake, creating rose-like swirls. Repeat with remaining colors of icing. You may find that there will be some areas in each row that don’t get fully covered, to fill in the little empty spaces just squeeze in some icing, in a curved shape (like a ”C”) to mimic the rest of the swirls a bit. For the top of the cake
You can a combination of swirls and some “C” curves for a looser, wavy effect.
Once fully frosted, store the in the refrigerator until ready to serve.ENJOY!!
