How to Use a Pan Extender

Watch this quick video to learn how you can use a pan extender with your sheet pans to bake delicious cakes with ease!

You will need a sheet pan and an extender, plus parchment paper and a release spray. Place the parchment paper on the sheet pan and place the extender on top of it. Spray the pan, making sure not to miss the sides of the extender. Pour the batter into the pan filling it about 3/4 of the way to the top. Bake the cake according to the recipe directions and then gently remove the extender. Using an extender you can prevent the sides of the cake from over-baking, making every bite just as good as any other, and you can eliminate trimming. If you are looking for aesthetic appeal, an extender also allows for straight sides.

    we have several different brands of this.we use to make sheet cakes a lot.this brand is much thinner and cake sticks to it even with using brand name spray.
    Thank you for your feedback! We’re sorry you did not prefer this product. For recommendations, please contact our Customer Solutions team.
    Works perfectly for making thinks like brownies, cheesecake squares, cornbread and my favorite, cinnamon rolls. I do wish there was an extender like this without any of the corner notches since cake batter runs out, but this design lets you get closer to the corners I presume.
    These are great for extending the height of your half sheet pans. I have used them for cinnamon rolls. I do not know whether it will work for thin cake batter because it might leak out from the edges unlike those full stainless steal ones which work for anything but is 5 times more expensive.
    Having a small oven I had no idea these even existed! These are perfect for a home baker as well. I use them for high brownies.
    This extender would be awesome expect that the sides do not go all the way down. It is sad that it doesn't keep all of the batter in. I would consider buying again because it is a good quality, although I might be inclined to check another type that would hold the food in better.
    This extender is the perfect thing for all of my cakes. Using extenders takes up less space when not being used and allows me to use any pan to set it on.
    I like these pan extenders, I find they are great for layering cakes. My biggest complaint is the triangular cut outs on the bottom corners of the pan.. Unfortunately, it makes it quite hard to bake any batters in this pan.
    works well enough. mine came in and was slightly warped. the brownies I was trying to make seeped out the bottom. but I do believe if the pan was not warped it would have worked fine.
    We appreciate your feedback! We’re sorry this is defective. A Customer Solutions Representative will be contacting you soon.
    We absolutely love these pan extenders. Wish we'd known about them sooner. They are what have changed the look of our signature cinnamon buns from ok to WOW OK.
    Great quality! Works perfectly to convert a half sheet pan into a 2" deep cake pan. I was worried that the product might be flimsy but it is very sturdy. So happy that I purchased them.
    I bought two of these 2 inches high half size aluminum Pan extenders so I can make a cake as my customers want. Made of s good quality metal. Very good find!
    Great sheet pan extender to bake cakes. Gave 4 stars because corners are not closed causing batter to leak. As a work around we folded parchment paper around the corners.
    Would be great if this was nonstick! I use a lot of spray to ensure easy lift off. Wish I had more uses for it, extender does what it says. Makes great cakes without having to invest in multiple size pans.
    My first time using a pan extender! works well.. you just put it on your sheet tray! the corners are curved however so i put parchment to cover to prevent leakage
    I am not a fan of this extender. My main complaint is the size - I expected to use it to bake a half-sheet cake, but the inside area is significantly smaller than a half-sheet, and I would not feel comfortable selling a cake made with this extender as a half-sheet cake. Also, my first time using it, I made an oil-based cake and the batter slipped under the extender, and, while baking, spilled up over the sides of the sheet pan resulting in a huge burned mess in the oven. I would give the item one star, but if you do not need a cake that is specifically a half sheet, and you are using a thicker batter, the extender can be used to bake a product with nice, sharp corners and straight sides.
    Thank you for the review, Attia! We are sorry this didn’t work for your application. For your convenience, we’ve posted the item’s dimensions on the product page.
    I was looking for something that would give me nice clean edges and also help prevent baked goods on the outer edges of my pans from getting browner than the center, and these work perfectly. They fit nicely in a half sheet pan, and are easy to remove once you take your product out of the oven. I use them for rolls, brownies, and bars, and am sure I will find other applications as well. I highly recommend them!
    I bought this with the intention of baking a large cake but ended up finding that it did not fit my baking sheets as I thought they would. The corners of the extender taper up so, if using a liquid batter, cannot contain the contents completely. I was under the impression that the extender would lay completely flat with no exposed areas on the baking sheet but that is not the case. I think this would work best with more rigid or dough-y foods.
    I was afraid my brownie was going to leak through the holes on the edges, but it works great - of course it depends on the batter. I lined the frame with parchment paper and have been able to bake perfectly straight brownies!
    Purchased the pan extender for our custard shop. It works very well in our flat pans to give us the increased height to build our thicker frozen custard sheet cakes.
    I really have yet to attempt to use this as more than a guide for my tiramisu. For baking it was about 2 inches larger than my half sheet pan due to the edges that are flat. I wish I would have known that before purchasing.
