Easy Peasy Rainbow Half Cake

So the 5 year old turned 5 and a half year old last month! And he had asked for a half-birthday cake! How could I not bake him a cake after he says to me, “Mamma, I love you more than a baby walrus loves his mother!”
I scoured the net and found this Easy Peasy Half Rainbow Cake. 
He loves M&Ms (which kid doesn’t!), he loves sprinkles and I had a box of pound cake mix sitting pretty in the pantry – so this cake was just perfect! 
When he saw the cake after coming home, he beamed and asked me why did I make a rainbow cake for him. I found myself saying “…because you are the rainbow of my life!” and both of us laughed and laughed and laughed!

Here are some step-by-step photos to show how (easily) I made this!

Easy Peasy Rainbow Half Cake
You will need half a cake (of your choice) that is sturdy enough to stand, M&Ms in the colors of rainbow or as many colors you want, butter-cream frosting, some sprinkles and some mini marshmallows. 
 Slather the top with butter-cream frosting and cover it with sprinkles.

Cover the side facing you with butter–cream and chill it in the fridge for 20 minutes.
 Arrange the M&Ms on it. If the sprinkles get onto the butter-cream do not worry about it too much, the M&Ms will cover the imperfections. But if you really want to, use a toothpick to take the sprinkles out. Chill again for 20 minutes and lastly cover the other side with butter-cream if you want to. I just found it easier to do it this way. Spread a little more butter-cream on the bottom and make it stand on the cake board and add few mini marshmallows to emulate clouds in the sky. 
Now get ready to wow your child!
