Decorating Rainbow Cupcakes

April 11, 2013 by Party Patisserie Filed Under: Cook 69 Comments

Whipping up these cupcakes for a party? Get everything you need to throw a fun and unforgettable bash from our party shop!

Today I’m happy to have Amanda Wright from Amanda Cupcake guest blogging and sharing with us how she makes her gorgeous Pastel Rainbow Fantasy Cupcakes.

She’s also going to share with us how to make and get the beautiful swirly, sparkly frosting that so many of you have been asking for.

UPDATE: When I first ran this guest post by Amanda, there was little information available about disco dust, which she uses on the frosting to get the look of glitter. While disco dust is labeled as non-toxic, it is not edible and should be used for decorative purposes only.

So, welcome Amanda! I’ll turn it over to you!

A True Story by Amanda Cupcake

One Starry Starry Night, while everyone else was dreaming, I swirled fantasies on top of cupcakes.

Little fantasies that tasted like vanilla almond rainbows.

Or vanilla almond rainbows that tasted like little fantasies?!

I re-created my starry night on the cupcakes by lightly sprinkling hologram silver disco dust on top of each frosting swirl ♥

My edible paint colors, that I swear by, for fantasy rainbow cupcakes and their frosting is the  Americolor Gel Paste in Electric Pink, Electric Yellow and Sky Blue.

(You can buy these at a local cake decorating supply store or online at Country Kitchen Sweetart).

The “Science” Behind the “Fantasy”

vanillaalmondrainbowcupcake

(the recipe for the batter):

  • White Cake Mix  (no generic labels, brand names only)
  • 1 1/2 Cups Buttermilk  (in place of the water on the box)
  • 4 eggs
  • 3.9-4 oz Vanilla Pudding  (the pudding gives it that “from scratch” texture).
  • 1 1/2 teaspoons of Pure Vanilla Extract
  • 1/3 Cup Vegetable Oil
  • Disposable Piping Bags  (for layering the rainbow colors on top of each other in the cupcake liners)
  • Light colored cupcake tin  (a light colored tin works better than the dark so that your bright colors don’t brown when baking)
  • White Cupcake Liners  (this recipe makes about 12-15 cupcakes)
  • Preheat oven to 325 degrees

Step 1: Combine all ingredients in stand mixer and whip together well using flat beater attachment.

Step 2: Using 3 separate bowls, pour about 1 1/2 Cups of batter in each bowl.

Step 3: 

♥ For Sky Blue:  Mix two small drops of Americolor Gel Paste.

♥ For Electric Pink:  Mix three to four small drops of Americolor Gel Paste.

♥ For Electric Yellow: Mix three to four small drops of Americolor Gel Paste. Bowl.

(I use more drops of color for the yellow and the pink so that the colors are really vibrant).

Step 4:  Stop and gaze at the beauty of your bright batter colors in each separate bowl.

Pour each color of batter into a separate disposable piping bag and snip off the tip.

♥ Cover the bottom of your cupcake liner with electric yellow batter.

♥ Repeat by piping electric pink on top of your electric yellow batter.

♥ Repeat again by piping Sky blue on top of your electric pink batter.

♥ Now you can add little swirly swirls of extra color, until your cupcake liner is filled 1/2 full.

♥ Bake at 325 degrees for approximately 18-22 minutes or until a toothpick inserted in the center comes out clean, then taste test. I did. The cupcake is…gone!

Look how pretty the cupcake liner looks alone!

The Rainbow Fantasy Swirl Frosting ♥

1 lb. of  Unsalted  Softened Butter in my Buttercream Recipe ♥

butter

I swear by Marshmallow Creme as the base for my frosting.

mallowcreme

I use 13-14 oz in my frosting recipe.

1 T. Vanilla Extract

Dash Salt (to lessen the sweetness a tad)

8 Cups Powdered Sugar

 

  • Use a spatula to scrape the fluff and the butter out into your stand mixer.
  • Mix well until fluffy and well blended.
  • Gradually add a pinch of salt and vanilla extract.
  • Slowly add the powdered sugar until the frosting reaches desired consistency.
  • (The more powdered sugar you add, the stiffer the frosting will be for decorating).

Just like my batter, I separated my frosting into 3 bowls.

frostingbowls

Then I mixed each gel paste color into a separate bowl (about 3-4 drops per bowl–you can always add more color if you want the color to come out more vibrant).

Electric Yellow, Electric Pink, Sky Blue and add White as a 4th color.

To pipe a multi-color rainbow swirl:  Stack each color of frosting on top of one another inside of a disposable piping bag. ♥  Your piping bag will look so pretty from the outside, like this!

stackcolorsinsidepipingbag2

 For a dreamy puffy fantasy swirl, I use a round Wilton 1A Piping Tip.  Before you stack the frosting inside of the piping bag, cut a hole in the end of the piping bag big enough to fit the tip, and slide the piping tip down into the end of the piping bag.

stackcolorsinsidepipingbag4

 

♥ No cupcake will look the same.  When all three-four colors blend together inside the piping bag you’ll start seeing greens, purples and turquoise colors swirl a fantasy rainbow onto your cupcake!

finalproduct

♥ HINT:  For the brightest colors possible use a fresh piping bag when you need to refill the frosting.  This prevents colors from turning muddy or brown.

The final product.  My signature rainbow vanilla almond fantasy cupcakes.

    Why use plain white in the frosting bag too? Wouldn’t that just come out as white stripe on the cupcakes or is the white necessary for the frosting to look that way?

      Because of the intensity of the colors, they’ll bleed and dye the white, so it’ll be a lighter color of the intense colors before and after. When doing this, like she said, the colors will mix as you squeeze your bag. Also, instead of wasting all the piping bags while building your cupcakes, you can use zip-lock bags with the corner snipped. Also, disposable piping bags can be washed and used more than once when in a pinch for funds…

    Did you only use disco dust for the shimmer on the frosting? The seem to have an over all summer that’s more than just what disco dust would add like they were dusted with a luster dust too?

    Hi Debbie,
    I’m doing a practice batch of these cupcakes for my grand daughter’s birthday.
    Two issues:
    When I was coloring the cake batter blue – it turned green because the batter was yellowish. (usually with white cake – you use only the whites but the recipe didn’t specify only whites so I used the whole egg). I wound up using alot more color which I really don’t like to do.
    The cupcakes sunk.
    Thoughts??????
    Thanks!

      Kerrie,
      Several things would make your cake sink. Too low of heat, under baked, too much oil, oven opened before minimum bake time, and over or under beating. If you have detailed info I could help narrow down the problem.

      Usually with a white cake mix, it’s suggested that the yolk is removed to prevent the yellowing of the mix. I don’t know if she forgot to mention it or if she does something else.

    Just curious, where does the “almond” come in to play? Is it the technique? The type of frosting? I don’t see any “almond” listed anywhere in the instructions. The cupcakes look great, though!

      I’m thinking you can use almond instead of vanilla, as no vanilla is shown and almond would give it a really yummy taste.

      I think the ingredient is supposed to be almond extract instead of vanilla extract. The picture shows almond extract, yet the ingredient list states vanilla extract.

      Hi, Denise! I bet that you maybe baked with dark muffin pans? Dark pans, as I’m sure you know, heat up faster, and cook faster. So your cupcakes may have just baked quickly on the outside, and didn’t have the chance to heat up on the inside. A safe method is drop the temperature by at least 25 degrees (I.E. this recipe would have been 300 degrees), and then checked your cupcakes about 12 minutes in. I’m drying the same recipe with my own dark muffin pans right now, so hopefully my advice works for mine, too! I’m really hoping for those colors!

    Disco dust is not edible. It is PLASTIC CRAFT GLITTER. It’s meant for use only on things that will not be eaten. Doesn’t matter that it’s non toxic–it’s still plastic.

    To keep something edible, edible glitter made from gum arabic, sanding sugar, or gelatin should be used

      There are many good “from scratch” cake recipes out there. Most professionals need to keep scratch recipes proprietary. The ones found online also work well with the coloring technique here. My daughter makes cakes for local events, and loves the ones on food network.com, also all recipes.com has good resources. But most of ours were passed from one generation to the next. Any you find can be adjusted to fit your personal tastes.

    These cupcakes are super cute. Been making them like this for years. My problem is with the mixing portion and the frosting. Not everyone has a fancy Kitchenaid or other stand mixer that allows them to produce all these liquid-less mixtures. This frosting recipe followed as written broke my mixer before I could add milk to thin it down. Thanks for not thinking of those who cant afford $500 mixers when publishing your fancy ideas.

    Hi, just thought I’d throw this out there, but did you know there is something called “edible glitter?” It may not be a metallic hologram, but it comes in pretty colors and adds a pretty sparkle to frostings. If you can’t find it in your local craft store, in the edible cake & cookie decorating section, just do a search for it on line.
