I use it to extend the height of my pan to proof my croissant dough. And the height fits my croissant after proofing. My croissant size is 7.5cm by 13cm and it can hold up to 21 croissants of that size.

Yi L. from LIU YI DA LLC on 10/11/2019

Very happy with these. We have 4 of these that we use to spread our fruit/nut purees on sheet trays before we dehydrate them. They are durable and holding up very well after being used daily for 3+ years. Easy to clean, lightweight, but heavy enough to stay in place. Great tool.

William B. on 11/26/2018

These are great and they hold in the liquids pretty well. They do good with baking to the core, however, I would still recommend using something in the middle to cook the core better.

Taylor B. from Taysty Treats on 06/22/2018

We have only really baked biscuits using these pan extenders but they look like they'd work great for cakes, as well. May have to use a liner to prevent seepage.

Heidi G. from Deep Creek Coffee Co on 02/13/2018

This extender is the perfect thing for my full size cakes! I can use regular full size pans without buying specialty pans for my cakes.

Michelle B. from Michelle's Scrumptious Bakery on 02/07/2018

If you bake a lot of full sheet cakes, you want to have these pan extenders ! Cakes and bars come out perfect on the edges, also they are easy to store

Irene B. from American Pie Bakery on 02/01/2018

Creating a sheet tray sized cake pan has never been easier. We use ours to make a sheet tray sized ice cream pie and it works great and going in and out of the freezer has held up very nicely.

Young L. from Younglife Saranac Village on 01/30/2018

This pan extender is perfect for brownies and bars. We line it with parchment paper so that nothing sticks to it and it makes it easy to wash.

Baljit D. on 01/07/2018

These have been Great! they are easy to clean, and they work better than the composite material we had previously ordered. this is much easier to clean without the staining.

Micah C. on 06/19/2017

Performs as expected. Bought a couple for large production camp kitchen. Does well with brownies and thicker cake batters, just wished the corners were sealed to prevent batter from leaking.

Kirt J. from Tim Horton Children's Foundation on 05/15/2017

Just what we needed to make those larger sheet style cakes or brownies to hold the batter in place on the sheet tray while baking.

Damian S. on 04/25/2017

This is the most amazing thing ever! If only I knew about this years ago, the money I could have saved by baking my own full sheet cakes. It works great, all you have to do is use non stick spray and it lifts effortlessly.

Diane L. from SOD on 03/08/2017

I really like this 2 inch tall full-size aluminum pans expand extend it's well-made and constructed I got it used for making sheet cakes and big trays of cornbread for my restaurant

Bistro L. from Place To Be Bistro on 02/28/2017

Absolutely love using these pan extenders. They make it very easy to make large batches of cake! There is a little cake that escapes out the bottom of the extender but not enough to make a difference. Great purchase.

Jennifer K. from The Windmill Bakery And Coffee Shop, LLP on 12/26/2016

This is a nice 2" full size pan extendar this will make the full size pans 2 Inches higher so this is great for big cakes when you need them to be taller

Lj F. on 11/08/2016

This pan extender is great for making cakes and brownies and such with a full size sheet pan. It bakes well and clean up is easy. It's also made well.

Tonya L. on 09/12/2016

This product is great for baking! I enjoy using it for cakes and brownies to get it that extra stretch! Great Product for baking use!

Jasmine J. on 07/21/2016

I'm not a huge fan of the notched corners, which is the reason for the 4 star review. Otherwise, we use these every day for baking sheet cakes and building layer cakes. We line them with aluminum foil and bake all sorts of fillings and goodies.

Danny D. on 07/18/2016

The 2" Full size pan extender is brilliant and has made baking cakes, rolls, brownies and other baked goods so easy. One of the best purchases I've made this year.

Thomas B. from Laura K on 07/03/2016

We use this to keep rolls from falling off the edge of our flat sheet pans and they work perfectly! Great quality and long lasting. Would purchase again.

Daniel S. on 05/26/2015

WOW can I bake better sheet cakes now that I have this workhorse in my arsenal at the bakery, they turn out great - just remember to oil the sides for release.

Marianne C. from Local Foods Bakery on 02/16/2015

I use these for brownies, granola bars, and other baked squares. They fit well in a standard-sized sheet pan, seem really sturdy and clean up fairly easily after baking.

Michael H. on 02/13/2015

These extenders are a great buy. They really do the trick and fit nicely in our full sheet pans to make a big an full sided cake for us.

Tyler B. from Barton's Flowers And Bake Shop, LLC on 03/01/2014

I got this item for making cakes in a standard full size bakery pan, they fit nicely and allow us to bake a really nice cake without running over.

Phil R. from Oak Hill Bulk Foods, Inc. on 02/19/2014

This is a great product and the price cannot be beat. I use this for full sheet pans of brownies & it keeps the edges perfectly shaped.

Justin R. on 05/30/2013

This is an excellent pan extender. I was surprise at the quality of the extender and how durable it is. It was an amazing purchase.

Jennifer M. on 11/16/2012

These are excellent pan extenders, we use them all the time to make brownies, cinnamon buns, cheesecake squares, and to stack sheet pans without compressing product.

Chris S. from Mountain Oven, LLC on 07/27/2012

Our restaurant needed this pan extender in order to make custom mousses for the holidays. They allow any sort of batter or dough to rise in a standard baking sheet without overflowing. Excellent price and quality.

Kevin S. on 04/23/2012

First time to order these. We use them with sheet pans for when we make cinnamon rolls. They are light weight but hold up great.

Eileen C. from Prescott Pines Camp on 07/01/2011

I had been trying to find anyone who used it online for a while but hadn't so I decided to take the plunge. This product is a Godsend for my business! This solved my problem of finding a way to bake full sheets of brownies without the edges burning or the brownies spilling over the sides. The only problem I have is that since they are so light, I do have some batter on the sides. Not enough to cause any concern, but it does happen. Parchment paper solved that problem. Just line the pan with butter and overlay the parchment paper on top of the butter, butter up the inside of the pan extender, and set on top of the paper, pour in your batter, and presto. Seems like a bit of extra work, but it is a quick permanent solution to my baking problem.
