Okay, so the other day I had this wild idea. I needed to frost a ridiculous number of cupcakes for a big family get-together. Seriously, like, mountains of them. My regular piping bags? No way. I’d be refilling them every five minutes, and frankly, I just didn’t have the patience for that.
I thought, “Right, I need the biggest piping bag known to man.” Maybe not quite, but definitely bigger than anything I could buy easily.

Finding the Right Stuff
First things first, I rummaged around. What could I use? I needed something strong, food-safe, and big. I found a roll of that heavy-duty plastic sheeting we used for painting once – but hang on, that’s probably not food-safe. Okay, scrap that. Then I remembered those giant, super thick freezer bags I bought ages ago for storing bulk stuff. They were pretty massive. Not exactly sheeting, but maybe workable.
So, I grabbed one of those big freezer bags. Like, the really huge ones. Also needed:
- Sharp scissors
- Strong packing tape (the clear kind, looked cleaner)
- My largest piping nozzle
Making the Monster Bag
Alright, here’s what I did. I took the giant bag. It was already sealed on three sides, which was kind of handy. I figured I just needed to make one corner into the pointy bit for the nozzle.
I decided which bottom corner would be the ‘tip’. I snipped a tiny bit off that corner first. Just enough so I could eventually push the nozzle through.
Then, the tricky part. Getting the nozzle in. I pushed my biggest round nozzle into the bag, aiming for that little hole I just cut. It took some wiggling. Once the end of the nozzle poked through the hole, I needed to secure it. This is where the packing tape came in. I wrapped tape tightly around the plastic where it met the nozzle base, trying to create a good seal. Went around a few times to be sure. Didn’t want frosting exploding out the sides.
The bag was basically ready. It looked less like a sleek piping bag and more like a weird, giant plastic cone sealed at the top (the original bag opening).
Filling The Beast
Now, filling this thing. It was floppy and huge. I grabbed the biggest mixing bowl I had, the one full of buttercream. Trying to scoop frosting into this giant, flimsy bag was… a challenge. It kept collapsing.

My solution: I stood the bag up inside a tall, sturdy pitcher. This held the sides up reasonably well. Then I started scooping the frosting in. And scooping. And scooping. It took quite a bit! I made sure not to fill it all the way to the top – learned that lesson the hard way before. Needed room to twist it shut.
Once I had enough frosting in there (probably enough for a small horse), I carefully lifted the bag out of the pitcher. I squeezed the frosting down towards the nozzle end, then twisted the top end of the bag really tight to keep the frosting from oozing out the wrong way. I used a strong rubber band to secure the twist, just for good measure.
The Moment of Truth
Okay, time to pipe. I picked up the bag. It was heavy! Way heavier than a normal piping bag. Holding and squeezing definitely required more muscle.
I did a test swirl on a plate. The tape around the nozzle held! No leaks. Success! The frosting came out smoothly, thanks to the big nozzle. It was a bit unwieldy, controlling the flow took some getting used to because of the sheer volume and weight.
But honestly? It worked. I frosted all those cupcakes without having to stop and refill once. It was messy, a bit awkward, but it saved me so much time and frustration from constant refilling.
Was it the prettiest piping bag? Nope. Was it practical for everyday use? Probably not unless you’re doing bulk baking. But for that specific massive job? Absolutely worth the effort. It got the job done.
