Buttercream Stripe Cake with Rosettes

filed under: Rose + Rosette Cakes on April 24, 2016

This blue and white stripe cake with rosettes was not what I expected it to be… especially when you see why at the end of this post!

How to Make Stripes in Buttercream


To make this cake you will need:

Chocolate Cake (I used box mixes for convenience)

  • three 12-inch round layers for the bottom (1 box mix equals one layer for the 12-in cake pan)
  • three 8-inch round layers for the middle section
  • two 6-inch round layers for the top

Buttercream recipe (I made five batches this recipe (about 10 pounds) and used clear vanilla extract and pale butter)

Simple syrup

Food color (I used McCormick’s neon blue, neon pink, yellow, and blue + red for the purple. You can use this guide)

straws or wooden dowels

small offset spatula

bench scraper

1M tip (or any large star tip) and (two) 2A tips

How to Make Stripes in Buttercream

Because of the size of this cake I had to bake the layers on one day then assemble the next day.

I used simple syrup to ensure my cake layers stayed moist and fresh.

When you are ready to assemble the cake, place one 12-inch layer on board or cake stand. Cover with about 1 cup of buttercream and smooth out. Repeat 2 more times so that you have a 3-layer cake.

(See: How to Build a Layer Cake)

Cover in a crumb coat and chill until ready to assemble the entire cake. (Place in freezer for 1 hour or in the fridge for up to 3 days.)

Now move to your three layers of 8-inch cake. Stack them into a 3-layer cake and cover in crumb coat. Chill in refrigerator until ready to assemble the cake.

Stack the last two 6-inch layers and cover in crumb coat. (Place in freezer for 1 hour or in the fridge for up to 3 days.)

Prepare buttercream: I made five batches of my buttercream recipe above which ended up being about 20 cups. I made one entire batch of it blue (4 cups), left two batches white (8 cups), one batch pink (4 cups), then split the remaining frosting between yellow (2 cups) and purple (2 cups).

Place all colored buttercream into pastry bags.

White frosting will be used for layers and crumb coats. Any remaining will be used on exterior of cake.

How to Make Stripes in Buttercream

Take 12-inch cake out of the fridge and insert wooden dowels or straws. I often use straws and find they work ok for lighter cakes. Wooden dowels are recommend for most tiered cakes.

Place cake on a rotating cake stand.

Drop 2A tip into an empty pastry bag. Grab your blue frosting (that is already in a pastry bag) and cut off the tip. Drop the bag of buttercream directly into the bag with the 2A tip. (You can see exactly how and I why I double bag here)

Repeat with white frosting.

Starting at the bottom of the cake apply pressure to bag and pipe out a line of blue frosting. Go slow and steady until you get comfortable with this movement! Piping with one hand and slowly turning with the other hand is the best way to do this. Go around the entire cake.

Repeat this with white. Then blue.Then white. Keep adding a new stripe around the cake until you reach the top of the cake.

Now take your bench scraper in one hand and the farthest edge of the rotating cake stand in the other. Press the scraper into the frosting and slowly start to turn the rotating cake stand while holding the bench scraper steady. Make sure you go around the entire cake at least once.

Take the very chilled 8-inch layer cake and gently set on top of 12-cake on rotating cake stand.

Repeat stripe process.

Finally, place the 6-inch cake on top of the 8-inch cake and repeat the strip process.

Here is a video on how to put this cake together:

Once your cake is assembled and the stripes are in place you can go back in and add the rosettes.

I wanted the top layer of rosettes to curve so I added a mound of buttercream underneath.

Now. Are you ready to see what the cake looked like when I delivered it?

Why oh why? I made this cake for a high-schoolers production of Eliza (My Fair Lady) and based it off of the play flyer.

Turns out I got the colors wrong. *bangsheadrepeatedly*

So! I scraped all the rosettes off the cake and re-scraped the sides and started over. Re-scraping meant that the lines were less straight and just look messier overall, so I was bummed about that.

Then I decided to go an entirely different route with the top… I wanted to make it a bit more like the big hats that Eliza would wear. But then I went to add it to the cake and it was wonky and so I had to fill in with some “petals” and my proportions got really skewed and it all just a BIG MESS.

OH MY WORD I am so embarrassed. Thank goodness that it was charity and therefore FREE and no money was exchanged.

But! It still tasted good (I think) and hopefully people will understand that bakers make mistakes and forgive me as they are enjoying a nice big piece with loads of buttercream. 🙂

    I actually love the look of the 2nd cake top- don’t be embarrassed!! I’d in fact love a tutorial on how you made the top flower for a future post.

    • Amanda says:

      Will work on that! 🙂

  • Pam, in NC says:

    I am *very* slowly learning that the less perfect creations can be loved just as much!! I used to be totally bummed about things that turned out “less than”, until I finally started cutting myself some slack and realizing that while they weren’ MY “perfect”, they were others’ “very darned good”!! 😀 I actually like the blue and white cake best!

    • Amanda says:

      I like how you think Pam. These are wise words! 🙂

  • Cait says:

    I would also LOVE a tutorial for that giant blue flower! And I’m glad you were able to fix it without having to make a whole new cake, but aren’t you just a little sad that you don’t have a whole 3-tiered cake that you just HAVE to eat? Oh darn….. 😉

    • Amanda says:

      LOL I will work on that tutorial!

  • cris says:

    Oh goodness! Your “failures” look way better than my successes! I love the all blue/white one, particularly the flower on top and I think it looks very much like an Eliza hat, she was a bit wonky herself so it’s perfect in its “imperfection”. ????

  • ell f. says:

    This cake is a winner! I also enjoyed watching someone decorate a cake left handed, a rare treat that I appreciate.

  • Donna says:

    I love this cake and think your “wonky” rose on top is lovely. I thought it was intentional. This really is an incredible cake!

  • Megan says:

    I prefer the blue and white cake. It looks fantastic. I am certainly going to attempt the stripes at some stage!

    • Amanda says:

      Have fun!

  • Julianne @ Beyond Frosting says:

    Oh man!! Well good for you for saving it and not having to start all over. It is still GORG! I dream of making a layer cake one day!

  • Aaryne McEvoy says:

    Hi…I just wanted to say that I love the new website look and your tagline is fabulous!! Very happy and fresh. Have a great weekend! Aaryne

    • Amanda says:

      Thank you!

  • April says:

    Is there a board at the bottom of each cake layer?

  • Bushra says:

    You are an excellent baker… and the cake looks absolutely wonderful….

  • Mira says:

    The cake looks yummy.
    Can i have the recipe for butter cream please?
    Till now i found so many but there is a secret that no one wants to share,and my butter cream wasn’t good .
    Thank you!

  • Sybil Clouatre says:

    I would love to take a cake decorating course! Know of any?

  • Fran says:

    I like both cake’s, but I think the blue and white is prettier.

  • Pamela says:

    I just dropped a loaf of banana bread trying to test dinner this a.m. Boyfrnd is try in to make me feel better about it and I know it is still delicious just messy with the broken top. Can you somehow reuse the colo buttercream you scraped off? Seems like a lot of waste if not.

  • Lynn says:

    Very cute. 🙂
    How much frosting (with all the colors) did you end up making/needing for the 3-tier cake?

  • Carrie says:

    Both of these cakes are beautiful! I’ve been decorating for 15 years now, and if there’s one thing I’ve learned it’s that someone is always going to have something negative to say. Just because one person doesn’t like the color combo doesn’t mean the next person wont. All of your cakes a GREAT and I love watching your videos! Just keep doing you!

  • Freda says:

    I need to know the tip size you used in piping frosting stripes onto cake…. looked like the large hole tip… sorry don’t know numbers for size..
