What You Will Need

  • 1 dozen baked and cooled cupcakes

  • Pink, purple, and blue gel food coloring
  • 1 piping bag fitted with an open star 1M tip (or equivalent)
  • 1 liter yogurt container
  • Spatula

Step 1
Divide your buttercream into bowls. Using a touch of gel food coloring, tint each of the three buttercreams a different shade, mixing it with a spatula until it’s tinted.

Step 2
Fold the edges of your piping bag open over the edges of the yogurt container. This will make it easier to fill your piping bag. Using your spatula, place the pink buttercream vertically in a 1/3 of the piping bag (as shown above). Next, place some blue buttercream in the piping bag, and finally, insert the purple buttercream. Don’t worry too much about perfectly dividing them into thirds as the colors will all run together once you start piping anyway.

Step 3
Remove your piping bag from the yogurt container and twist the end. Squeeze the piping bag, letting the colors run. You can test this on a paper towel or a plate. Okay—you’re all set!

Step 4
We’re going to pipe the rosette swirl. Basically we’re making a counter-clockwise swirl on the top of the cupcake. Start in the center of the cupcake and start piping.

  • Would love to know how it works out for a “non-professional” and hear any feedback. People who’ve done things 1000 times always make it look so easy :)

  • hi karen! yes the yogurt container is the key, and always try to use complementary colours – ie, colours that blend together nicely! i don’t usually pipe the colours into the bag but it’s an extra clean way to do it (but it creates more to clean up!). i usually use a spatula and try to get my colours as close to the side of the bag as possible! good luck! ^__^

  • hi courtney! try the yogurt container trick, and use complementary colours. this really is an easy technique to get two or three colours (or more i suppose!) of frosting in one piping bag. have fun!

  • When I want to blend more than one color, I find it much easier to insert 2 or 3 disposable bags, each with a different color, together, into the decorating bag. They’re also easy to refill, just pull them out, and repeat.

    I have one suggestion for you, when piping a rosette on top of a cupcake. When you are at the end, tuck the frosting tail under the previous swirl. It would look neater than having the tail sticking out to the side.
