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.

    These decorating bags are great for so many things! They are a nice thickness and are very well made. They don't blow out the side of you are using a thick icing like other brands I have tried.

    from Kern Valley Farm Posted on

    We purchase a variety of pastry bags regularly. After much trail and error we a very pleased with the ateco 12" they seem to be a better mm thickness than competitor has to offer

    I'm completely in love with these bags. Not only did I save money, but I'm also saving time. I no longer have to deal with cheap bags bursting.

    These bags are much more sturdy than I had hoped. They fit both Ateco and Wilton tips and couplers, and any size at that. Plus they're clear so you can see inside so you can avoid air bubbles along the side or more carefully add in multiple colors. I think I like them even more than my reusable bags! Although they're sturdy enough that you could even wash them out and reuse these as well! Phenomenal value!

    Fits both Ateco and Wilton tips and couplers, all sizes.

    I love these bags, so sturdy and convenient. I personally use them the most for drizzling chocolate or glazes where a larger bag is just not necessary. So economical too!

    from Krumm's Baking Co Posted on

    I was excited to see pastry bags at such a reasonable price but while these bags are strong, the large awkward seam and sticky outside has made these bags a no go for me. Will have to stick with another brand for now

    These bags are such a time saver. I really got tired of making pastry bags with parchment paper. This way I just put in a coupler in the bag, cut off the top of the plastic bag, put on the tip, put on the other end of the coupler on and fill with icing.

    I used Ateco 4712 12" Clear Disposable Pastry Bags (August Thomsen) to pipe buttercream flowers

    You can't get a better deal on disposable piping bags! I use these for French macarons, and this size is perfect for my batch size. They are also great for the buttercream fillings. I love that I can use these once and not feel guilty because they are so cheap!

    Very convenient! The bags are rolled up in a small box so it does not take much space. Also holds a lot of filling and is durable.

    Posted on

    These bags are great for small amount of royal icing or buttercream. The don't burst when you apply pressure, and they are significantly cheaper than many others on the market, really worth the cost.

    Posted on

    Nice and sturdy piping bag. It is a nice size for doing smaller projects. If you are going to do a large amount of piping I would recommend the 18" bags.

    from All Over Creations Posted on

    The bags themselves are great but the pacaging could be better. I don't like the roll for a busy bakery, I end up fighting with it or pulling the bags out a head of time so I'm not wasting time fighting with the box.

    from Sweet Gourmet Cafe Posted on

    These bags come in a bos like tin foil does it's good to carry in your supply box. Also great price for a box. Definitely get more than one next time

    from Foxland market Posted on

    I love the larger size of these bags, but would prefer a brand without the seem down the side. Since I use these primarily with buttercream it is nice to have the non-slip surface on the outside to keep the grip.

    from Astonishing Cakes Posted on

    I love these piping bags so much more than the reusable canvas ones. Cleanup is so much easier and more convenient seeing as I don't have to wash these out. Very durable too!

    Posted on

    Great bags a great value. I use to buy my icing bags from another company. Then I found these on here and I haven't bought anymore from anywhere else since. I like the bigger bags better though.. theses are great too.

    Best. Piping. Bags. Ever! Seriously. You will not be disappointed. My favorite part is that their disposable. I've tried the reusable kind and I'm just not a fan. Be wary of other brands - this is as good as you can get.

    from Sunshine + Sugar Bakery Posted on

    Macaron batter

    I love these pastry bags! They are sturdy yet flexible enough to easily fill and twist. This is the perfect size for delicate decorating and writing. Best part is that they are recyclable so I don't feel bad about using disposables.

    from Monsoon Sweets Posted on

    A must for any bakery that decorates cake, cookies, etc. Bag lasts through a few washings and uses. If you use dish soap on it directly, it cleans up nicely.
