How to Pipe a Rose with Buttercream Frosting

Ever wonder how to professionally decorate your cake? Watch this short video and learn how to style up your next cake with a classic buttercream rose.

Use these simple steps to professionally add a buttercream rose. You'll need a spatula, rose tips, a leaf tip, couplers, a flower nail, a rubber spatula, and piping bags. Begin by squeezing cream onto the flower nail in a circular motion, creating a lump with a tip on it. To create the layers of a rose, squeeze cream in an short arch motion and continue rotating the rose until you have the desired amount of layers, or petals.

Ateco Piping Bags, Short Spatulas and Pastry Tubes

Looking for just the right tools to decorate your cakes with? Try the Ateco piping bags, short spatulas, and pastry tubes! These tools will help you create weaves, ribbons, scalloped edges, and more that will leave customers impressed every time.

Hi, this is Julie Bashore from the Sugar Arts Institute. Let’s have fun with some of the Ateco piping tips. Working with their disposable piping bags that come on a roll, they tear off really easily, I like to work with the smaller 12” bags but they also have 18”. Working with a coupler, remove the nut from the base of the coupler and place the base in the bag as tightly as you possibly can. Working with a pair of scissors, above the screw marks, just cut the edge of the bag and remove that. And then you’re going to choose the piping tube that you’d like to work with, place it on the top of the coupler, and screw it down firmly. This is a piping bag stand; it’s very convenient, especially if you’re piping alone or you don’t want to interrupt anyone to fill the bags, it holds the bags really well and you can slip your icing in there. This is the short-ended Ateco spatula which is quite wide so it’s really convenient for picking up the buttercream. Pull the bag up, place it on the table, and spread the buttercream down to the end. And then of course it’s important not to forget to burp the bag. This piping tip that I’m using is a ruffling pipe piping tip, and it’s absolutely amazing how quickly it works. Have a look, come in close. Doesn’t that give an awesome ruffle? Let’s work with another tip. This is the shell tip; don’t forget to burp your bag. This is great for a border; in fact, I sometimes use it on the edge of my ruffle. It gives a really nice shell design. The tip itself is curved so it gives a nice puffy shell appearance to it. Ateco has a new set that they’ve brought out: polycarbonate plastic piping tips, they are large tips, very strong and very precise in the edging. This one is a basket weave design; it really makes an awesome border. Place the bag over the holder, again, don’t forget to push the butter cream all the way to the edge and burp the bag. It has two edges, a flat edge and a scalloped edge so this makes a great ribbon design; you can also wiggle it or make just a ribbon and also wiggle this. Flip it over and wiggle. Great for basket weave.

    We purchase several rolls of these at once. So nice to use and an affordable price over the other online retailers I have searched. Holds up well during piping.

    These bags are a great value, and don't take up much storage space. They are also a better price than I've seen in many places.

    such a great deal for the price! they are by far my favorite piping bags for medium to large size projects. I make a lot of treats such as cupcakes and cookies for a homeless shelter which I pay for out of my pocket. these bags are very cost effective and durable. I haven't had any break open yet. the dispenser roll box is a bonus as well. I will be reordering as soon as I need more!

    from Emmas Cakes Posted on

    I use all of the sizes of the Ateco disposable pastry bags. They are a great bargain and work well. The 21" size is a great size for bigger projects, like mountains of meringue or lots of buttercream.

    from Sugar Buff Posted on

    We order these pastry bags time and time again!!! They come in a convenient roll and is a very good size. Great for buttercream decorating and the bag is really sturdy

    You can never have too many disposable pastry bags and these are just the ticket! High quality but not a high price. Love these bags.

    from Buffi Cakes Posted on

    I love this disposable clear pastry bags not only because of the quality of plastic that is very thick and stretchy also, it came with the dispensing box!

    from Sugary and Savory Posted on

    I use these piping bags for so much more than piping frosting. They are wonderful for apllying sauces too. Strong bags, great size for almost any use.

    from Sweet Candy Finds Posted on

    These larger pastry bags are perfect for frosting several cupcakes without having to reload. It is yet another great quality product from Ateco, as usual.

    I've used the Ateco 12" and 18" pastry bags, and the 21" is a great addition to those, especially for larger jobs. I've used them for frosting, mousse, choux, meringue, etc. The dispensing box and bag roll make them easy to use.

    from Sweet Indulgence Posted on

    In my bakery, we use these most often to ice large batches of cupcakes. They work great because the plastic is very sturdy and the size is perfect for fitting enough icing in the bag that you can ice quite a few cupcakes in one go. Loves the box they come in too, perfect for storage

    from KMSK Kreations Posted on

    As a baker, I have to get things frosted fast, mess free and done correctly. These bags are great for that. Fill the bag, clip end and frost. Can be used with tips too.
