happy over the rainbow cake

Want to make everyone happy? Create a cake covered in rainbow colors, topped in ganache and sweet icing rosettes. It is the perfect cake to celebrate birthdays, holidays or any special occasion.
Step 1
Ingredients for White Ganache
½ Cup Heavy Whipping Cream
 
Bake and cool two 6" layers. Level and fill for a 6" high cake.  
Step 2
Divide icing into six 1 cup portions and tint rose, orange, yellow, green, blue and purple. Place icings separately in disposable decorating bags. Cut off 1¼" at end of bags.

TIP: Combine Lemon Yellow and Golden Yellow for yellow shown. Combine Violet add Rose for purple shown. 
Step 3
Place cake on board and position on turntable. Begin at bottom border, pipe bands of color, approximately 1" high, in this order: rose, orange, yellow, green, blue and purple. Reserve remaining icing. 
Step 4
Use icing smoother, and while turning turntable, smooth colors at one time. Use angled spatula to smooth cake top.  
Step 5
Prepare white ganache recipe.
   -  Chop white Candy Melts® (you can use a food processor).
   -  Heat whipping cream in saucepan, just to boiling point. Do not boil.
   -  Remove from heat and add chopped Candy Melts®, then stir until smooth and glossy.
Step 6
Pour cooled ganache into a disposable decorating bag, and cut ¾" off the end. Start at center of cake top, move turntable while squeezing bag until you reach top edge of cake. Allow to flow slightly off edge. Let ganache set until firm to touch, 15 to 20 minutes. 
Step 7
Fit six decorating bags with tip 1M. Separately fill with each icing color. Divide cake top into 6ths and lightly mark with toothpick. Pipe tip 1M rosettes in each color at marks.
