Learn How To Make A Rainbow Cake With Melted Frosting!

Sophia Gioiello

We’re a bunch of candy cravin’, sweet-tooth fanatics over here at JumbleJoy and just about swoon over any of the latest dessert trends.

Cupcakes continue to win our hearts as the perfect portion of rich, decadent cake, but intricately designed cakes are making their way to the top of dessert trends…and we can’t get enough!

Whether you’re making a surprise-inside cake, or a “Frozen”-themed Barbie cake, the options are endless! But we can’t help but question these recipes and wonder if any regular ol’ baker can make these or if you need to be a master of design to construct these extraordinary creations.

Thankfully, we have finally found a melted rainbow cake that anyone – and we mean anyone – can make!

Hungry Happenings shows us how to recreate the effect of melted rainbow crayons right on top of your favorite Funfetti cake. (Because you can never have too many rainbow sprinkles!)

Ingredients you will need:

2 Betty Crocker SuperMoist Party Rainbow Chip cake mix

Eggs, water and oil called for on cake mix box

4 tubs Betty Crocker Whipped White frosting

5 ounces white chocolate, finely chopped

1/3 cup heavy whipping cream

2 tablespoons corn syrup

Candy coloring of your choice

First, line your pan with non-stick tin foil just to make sure your cake comes out of the pan easily. Then whip up one of the boxes of cake mix.


Bake the first cake and let cool for 10 minutes. Make the second box of cake just like you did with the first. 2014-06-03-melted-rainbow-cake-step3-680x384

Once your cakes are cooled, cut off the mounded top and cut each cake into two even layers.


Cut a cake cardboard that is just about 1/4-inch bigger on all sides of your cake to create a base. Set one layer on the board and frost. Continue until all four layers are stacked and frosted.


Frost the entire cake and smooth out the frosting as best as you can. Hungry Happenings recommends freezing the cakes before frosting, and then again after, to get the smoothest frosting possible.


If you decided to freeze the cake, make sure to let the cake return to room temperature before the next step. She says the colored ganache won’t drip as nicely if you try to continue on with a frozen cake.

The easiest way to make the ganache is in your microwave. Stir together the white chocolate, heavy whipping cream and colored syrup, and then place in the microwave for 30 seconds.


Next comes the fun part! Set the raised cake over parchment paper and use a spoon to drip the brightly colored ganache over the cake. The finished cake will feature a swirled mess of colors on top and the colored dripping on the sides. Don’t worry – there’s no “wrong” way to do this part!


Allow the colored design to dry entirely until you pick up the cake to place on your platter of choice.


Slice and enjoy! Your guests won’t be able to take their eyes off of this masterpiece! Try it out for yourself and let us know how it goes. Happy baking!
