Rainbow Ganache Cake

cake

Welcome to post 2 in Valentine’s week here and at Confessions of a Cookbook Queen!

I guess this cake isn’t really Valentinesey…

But it totally could be…I mean, just use red and pink ganache…

The idea for this cake came from all those cute Melted Crayon Art projects all over Pinterest.  Have you seen those?  SO fun!

 

And even though rainbows aren’t your typical Valentine’s symbol I’m thinking that no one would be UPSET if a rainbow happened on Valentine’s Day.

Rainbows are basically love in the sky, so I think this totally makes sense.

 

Rainbow Ganache Cake

Rainbow Ganache Cake | Cookies and Cups This cake is pretty darn easy…I mean as far as cakes go.

I am by no means an expert cake decorator…as a matter of fact I have grown to moderately despise cake decorating.

After one too many disasters, I decided my patience level in not suited for cake artistry.  I am more of a slap it together kind of girl.

 

So this cake is perfect for me…simple frosting, drippy ganache, and swirled colors.  Basically you can’t mess it up…

Just bake your cake.

I made chocolate…but I am sure there are you girls out there who would take this whole cake to the next level with a swirled cake inside, or a rainbow layer cake.  Go for it.

I “crumb coated” the cake…which is a thin layer of frosting that you smooth on first and let set.  It just prevents you from getting cake crumbs in your final product.  It seals in all the crumbs.

Then I went over the crumb coated layer with a a smooth layer.

I used my recipe for buttercream.

Photobucket After you’ve frosted the cake, go ahead and make your white chocolate ganache.

Just chop up some white chocolate fairly finely…

Photobucket Now place your chopped white chocolate in a bowl and pour some nearly boiling heavy cream on top.

Stir the cream and white chocolate together until it melts.  If you need to, you can microwave it slightly so all the white chocolate melts.

Photobucket Next add some light corn syrup to the ganache.  This helps give it a little shine.

Then separate your ganache into bowls in equal proportions…the amount depends on how many colors you are using.

Photobucket I used Candy Coloring to tint the ganache…with the white chocolate in there, I was worried that regular food coloring wouldn’t work.

Photobucket I just added a little bit until I got the colors that I wanted.

Photobucket Then start with one color at a time.  Place a nice spoonful in the center of the cake and using an off-set spatula, or large spoon push the ganache to the edge, letting it drip down the sides itself.

Photobucket Continue around the cake cake alternating colors…

Your right! Easy is always better. LOVE this cake. Gotta try it. Never heard of the special colors to use with white chocolate. That’s why I love you and Kristan — I’m always learning something new and it looks easy enough for clumsy ol’ me can do it! Well, at least I’m not too intimidated to try.

Wow, that looks super pretty! I’m a bit uncoordinated when it comes to cake decorating, so this technique might come in handy the next time I want an impressive cake that I actually have a hope of pulling off!

My daughter would go crazy for this. Not only does she love white chocolate, she is a tie-dye fanatic. This might just be her birthday cake this year!

Guest

This is so cool Shelly! I bet it would be the star of a 70’s themed party too! I love the thought of making it valentines-y too! 😀

Guest
January 23, 2013 9:25 am

Beautiful! By the way, I would totally make a chocolate cake, too. Not only to keep it simple, but because it’s the flavor I LOVE. I was thinking, you could probably use this same concept of colors with King Cake…but as a layered cake like this and colored sugars instead of icing. Hmmm…. might be a little project for me next week. :)

Guest
January 23, 2013 9:48 am

What a FUN idea! My kids would love pouring the color over the cake. :)

Just wanted to let you know that your cake turned out beautifully! I had never considered making a multicoloured ganache before this moment. For a good friend’s birthday this year, I am going to surprise them with this cake as a Rainbow Dash cake. Instead of a chocolate base, though, it will be a sky blue base. The bronies are going to love it!

Made this delicious cake yesterday and followed all your instructions for the ganache. It was a big hit. I used regular food coloring and the colors worked out great. Thanks.

I’m totally envisioning this as a St Patrick’s Day dessert and sprinkling gold coins all around the bottom of the rainbow ganache drippings!

Soooo Cute!
