Preheat the oven to 350 degrees Fahrenheit and grease and flour 3 6 inch round cake pans.

In a mixing bowl, whisk together the flour, baking powder and salt.  Set aside.

In a separate bowl, cream together the butter and sugar with a hand held mixer or stand up mixer until light and fluffy.  Add in the eggs and cotton candy flavoring.  Mix until combined.

Then slowly add in the flour mixture and milk, alternating between each one, until both are fully incorporated.

Then pour the batter evenly into 4 bowls.  Color one of the bowls pink, one blue and one purple and then the 4th bowl undid.

Spoon the batter randomly into each of the 3 baking pans.  Gently swirl the batter together to make a marble pattern (be careful not to over mix).

Bake the cakes for 30-35 minutes until a toothpick inserted into the center of the cakes comes out clean.

Cool the cakes in the pans for 10 minutes and then turn them over onto wire racks and cool completely.

Beat the butter with a hand held mixer or stand up mixer for approximately 3 minutes until light and fluffy.

Reduce the speed on the mixer to low and gradually add in the powered sugar until combined.  Then mix in the milk and cotton candy flavoring until combined.

Divide the frosting evenly into 3 bowls.  Dye one bowl pink, one bowl blue and one bowl purple.

Level each of the cakes with a serrated knife.

Place one of the cakes on a serving plate or cake stand.  Add about 1/2 cup of frosting on top and continue this process with the remaining 2 cakes.

Place a thin layer of frosting around the top and outside of the cake for the crumb layer and freezer for 10 minutes.

Once the crumb coat is set.  Add another layer of frosting to the sides and top of the cakes.  Alternate between the colors on the frostings to get the swirl effect on the frosting.

Then place each color of the frosting onto the sides of a piping bag fitted with a large star tip and pipe multi-colored swirls around the top of the cake.

When ready to serve, style with cotton candy on the top and around the sides of the cake.  Then the cake is ready to slice, serve and enjoy!
