How to use a piping bag for frosting

Show-stopping, bakery-worthy cakes, coming right up. Perfect your frosting technique with our how-to video on assembling and filling a pastry bag. Watch the steps in our video to see how it’s done.


Instructions: Assemble your pastry bag, coupler, and tip.

The coupler goes into the bag first; then the tip is fitted onto the coupler from the outside.

Now, fold back the top of your pastry bag around your hand. Fill the bag about 2/3 of the way full with frosting. You can also prop the bag in a tall bar glass, rather than holding it.

Fold back the sides of the bag and press the frosting towards the tip using a bowl scraper.

Now you’re ready to frost!

Hi Nikki! You don't have to use the coupler, you can place the piping tip in the bag before you fill it with your frosting or whatever you're piping. The only downside to this is that you'll have to empty the bag to change the tip if you'll be using more than one. We hope this can help! Kindly, -👩‍🍳Morgan

I have a few piping tips that are too big for the thing that locks it in. Does it need that lock?

[snehajkadam]

Thank u muchh I'm confusing while using first time 😓😉❤🤗🤗🤗🤗

[ZsaZsaUmbra]

Does the bag go between the threads or should I make the hole bigger so the threads are out?

[phenix]

do you need a specific frosing though?

[madisoncarratelli]

[tanmayagarwal]

Should any part of the plastic come out of the bag? 😅
