How to Use a Pan Extender

Using a pan extender provides a final product with smooth, straight sides, and a uniform height, color, and texture, with minimized over-baking! Learn more about using a pan extender by watching this video.

When cooking with a pan extender, first place a piece of parchment paper on your sheet pan. Then set the pan extender on top of it. Coat the bottom of the pan and the sides of the extender with a release spray. Pour the batter to 3/4 capacity, and then place the pan in the oven to bake. Bake the batter according to your recipe directions and then remove it when ready. Allow the pan to cool off before gently lifting the extender. The sides of your cake should be straight and smooth, which makes trimming obsolete! Plus, using a pan extender will promote uniform height, color, and texture, while minimizing over-baking!

    These pan extenders are a great addition to any bakers kitchen. The work amazing for making cinnamon rolls, brownies, and other bar pastries. I purchased 2 and use them nearly every day!
    Love these pan extenders for my baking. No more over flows in the oven for me! The extender fits perfect in my half sheet pan. They also clean up real easy.
    Discovered this amazing tool in the baking program. They’re definitely a game changer being able to get those nice crisp lines. The quality is great and clean up is easy. Food comes right off of it.
    Easy to clean, resistant, batter doesn't lick beneath . Sets perfectly on half pan and let you cook cake batter or brownies without burning edges. Recommended
    these are awesome for sheet pans. nothing will stick to the sides on the sheet pan, and it makes leveling things really easy to do
    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.
