I don’t know if the universe has it out for me or what, but I swear to you all, the second I start making a conscious effort to eat healthy, I’m suddenly inspired to make all sorts of naughty treats. And not just inspired, like, “Oh, I really, really, really want to make some caramel corn,” but my brain suddenly starts putting together evil ideas for things I’ve never even made. I guess deprivation is great for inspiration, right?

I’m posting my scandalous little treat on Friday, but for today, I want to share a really cool tutorial. I kind of thought I was a genius until I told Sara what I was posting and she told me that she already has a tutorial all photographed. It’s kind of rough sharing a brain sometimes.

Not only is this super impressive (my 6-year-old told me that he thought the way my cupcakes were “designed” was awesome), but it’s a fun and easy way to implement different colors when you’re decorating cupcakes. Like for these Colorburst Cupcakes that Sara posted this last spring during March Madness.

For this tutorial, I’m just using two colors of icing, but you could easily use three (or even four if you’re feeling wild) different colors for a really cool rainbow effect. You can also play around with flavors, using different types of icing or adding different flavors to a something like our Perfect Cupcake Frosting and Filling. Chocolate and caramel, chocolate and peanut butter, chocolate and orange, orange and lemon, vanilla and almond, vanilla and peppermint, peppermint and chocolate…you’ve pretty much got unlimited options.

You’ll need icing, disposable decorating bags (one for each color and then one more to fit them all into), and a large decorating tip (like this, this, or this) and a large coupler.

The most basic thing to remember is that no matter how many different colors you’re using, you don’t want the final bag to be too full. So if I’m using two colors, I’ll fill each color bag a little less than 1/2 full with icing. If I were using 3, I’d fill them a little less than 1/3 full, and for 4, a little less than 1/4 full. Make sense?

After you’ve filled your bags, flatten them out and stack them on top of each other…

and then trim 1/2 inch or so off the tip of each bag and slip them into the bag fitted with the decorating tip.

Firmly squeeze the bag until you’re getting equal parts of each icing from the tip. I will say that it’s a little trickier if you’re using two different types of icing (like I am here) than if you use different colors of the same icing (like Sara did). If you do use two different types of icing, try to make sure they’re roughly the same consistency before icing your cupcakes, even if it means popping a softer icing into the freezer for a few minutes.

To ice your cupcakes, hold the tip close to the top of the cupcake. Using firm, steady pressure, squeeze the icing bag, starting in the center of the cupcake and moving around the edges of the cupcake and then one more swirl on top, moving back towards the center. I actually had a video tutorial of this at one point, but Dropshots spontaneously deleted all my pictures and videos (yes, Dropshots, I’m totally calling you out, jerks!), so I’ll try and get another one up today because it’s not nearly as complicated as it sounds.

Prepare yourself for oohs and aahs. And perhaps squealing. Also, your kids (and your spouse…and his/her co-workers…) will think you’re a rock star.

    I have never had any luck with trying to do the color stripe down the side of the bag before adding the 2nd color frosting. I can’t wait to try this. It makes so much sense. Thank you.

    Looks like chocolate & peanut butter cupcakes are on the way?

    Nicole Krell says:

    I love this idea! I’ve decided when I have my book launch party, I want the cupcakes to have swirled frosting! (Well, first I have to sell my book, but my agent is working on that.) I am so thrilled I found this website!!! You are two very talented ladies and I don’t even like to cook!

    Karla says:

    How do you get the icing into the icing bags without making a massively large MESS. Mine are always crazy messy and then when I squeeze out the icing, it comes out of the tip but also the messy part comes out of the end of the bag.

    • 7.1

      It can be tricky. One thing is to just be careful how full the bags are. You can also get ties and clips that clamp the opening of the bag shut so it doesn’t come out the top–just look for them in the cake decorating section of Walmart/Hobby Lobby/Michaels/wherever.

      Hope that helps! 🙂

      Heidi says:

      Put the bag on your hand (like a glove), but inside out. Put scoops into your open palm. Make sure the top edges are up enough that you can just flip it back after you’re done filling your palm. Now the frosting is on the inside and you have little to no mess! I do this all the time for frosting and it works fantastic. 🙂 Hope it helps.

    • 7.3
      Lisa G says:

      I put the bag into a tall glass, spreading the top of the bag down over the edge of the glass. It makes it so easy to just scoop the frosting into the bag.

    • 7.4
      Brittany says:

      Something I do is out the bag inside of a glass 🙂 pull the excess plastic down over the glass, and then use a scraper to load the frosting in 🙂 very fast and simple! 🙂

    • 7.5
      Lyla says:

      The icing is coming out of the end of the bag because you didn’t twist the end of the bag. If the twist does not stay, you can tie is together with a rubber band. If it comes out of the tip. maybe just put your fingers on the tips and it wont be as messy. Hopefully this helps!

    Michele N says:

    I too have tried putting the 2 colors in one bag and had issues. I’ve never thought about putting 2 bags inside another one. Will have to try this next time. Possibly for my daughters birthday, which is today but the party won’t be until next weekend and haven’t figured out what we’re doing yet. This looks almost fool proof! Thanks again!

  15. 15
    Natalie Lloyd says:

    I’ve done something similar, but I actually just plop spoonfuls of alternating colors in the same bag. You still get a swirl effect, but also get a third color sometimes where the two mix. You can also achieve a similar effect by taking your food color and literally painting stripes of color on the inside of the bag before loading the frosting!

    Suzanne Thompson says:

    OOO I cannot WAIT to try this.. actually it is a little cool out today, I feel a cupcake inspiration coming on! Thanks for this great tip!

    Blythe Forman says:

    A tip to make filling bags less messy AND not overfilling them: Fold a cuff down until the top of the bag touches the top of the coupler. Then fill the bag just to the top of the cuff. Keep the mess on the inside of the bag, and if you only fill to the top of the cuff you can’t overfill. Then unfold the cuff and twist the bag right at the top of the icing. The twist then goes into the v where your thumb meets your hand to keep it closed.

      Ang says:

      Awesome tip, Blythe, thanks! (And great tutorial, Kate! I’m actually tempted to make cupcakes today, with absolutely no need for them whatsoever. Maybe I’ll just order a new tip and wait for Friday’s recipe….)

  29. 29
    Traci says:

    The easiest way that I’ve found to fill the piping bags is to place them (with the tip in place) in the inside of a drinking cup or glass (depending on how big the bag is). Then just fold the sides over the top of the glass and simply fill it with frosting using a spatula. Then pull it out of the glass and start twisting/folding the top…the frosting will move down to the tip and you’re ready to go!

    Seriously love this tutorial – was wondering how to do this!

    Sarah says:

    Just wondering which frosting recipe you used for the two color frosting? I know when you add color gel to the cooked frosting it doesn’t work well (did it once and it didn’t look pretty, tasted good though). Was it your Swiss Buttercream? Which I might add is fabulous with blueberry puree. Thanks so much! Love your blog by the way, visit everyday!

  41. 41
    Lisa says:

    Awesome! You can also make swirls by running lines of gel food coloring on the inside of your decorator’s bag and using the same tip you mentioned in the original. The colors are very bright (at the first) and start to fade but last through the whole bag of icing.

    I once made neapolitan cupcakes and put 3 different coloured icings in one bag, it was messy and only a few worked as I wanted. This is such a simple solution I love it! No more messing but a lot more flavours 🙂 Thank you!

  78. 78
    Christine says:

    You can do this without wasting extra piping bags (expensive!) if you wrap your icing in plastic wrap like a ‘burrito’ first. The ‘burritos’ are tied at both ends, one end snipped off, and the snipped off end placed down into the plastic piping bag. Best thing about this is that you never have to worry about the icing leaking through the wrong end of the piping bag!

    If you make small ‘burritos’, you can place several different colors in just one piping bag. Very little mess, and you can quickly and easily refill the piping bag as you go. http://tinyurl.com/7dmqfv4

    the bag has to fit over tip, if using 2 how do open both bags i am not understanding .
