If you want a no-fuss, disposable way to bake cookies and keep your Ninja air fryer toaster oven clean, choose MMH 154PCs; if you need a durable stainless steel replacement tray set for a Gourmia French door air fryer, choose Ketofa Air Fryer Replacement.
• MMH 154PCs biggest trade-off: It is consumable by design — the disposable sheets run out, the liners are cut for one specific oven family, and the paper tops out at 450°F with strict warnings about preheating and direct contact with the heating tube.
• Ketofa Air Fryer Replacement biggest strength: A 3-in-1 set (basket, baking pan, wire rack) in food-grade stainless steel with silicone tongs, dishwasher safe and built to resist bending and warping — reusable hardware instead of paper.
• Ketofa Air Fryer Replacement biggest trade-off: Compatibility is narrow — it fits Gourmia GTF7655, GTF7460 and GTF7465 French door models only, and you must compare your original part sizes before ordering.
• Who each pick is for: MMH 154PCs is for the Ninja SP151 owner who bakes cookies and pastries often and hates scrubbing; Ketofa is for the Gourmia French door owner who wants one durable accessory kit for wings, fries and reheating.
This set is built around one idea: you should never have to cut parchment to fit an oven again. Everything arrives pre-cut for the Ninja SP151 air fryer toaster oven, so you pull a sheet out, drop it on the tray, and load it with cookie dough, croissants, pizza crust or pie. The 154-piece count breaks down into 100 disposable parchment sheets, 50 perforated disposable sheets and 4 reusable mats, which is a lot of baking sessions before you need to think about restocking.
The material story matters if you bake cookies often. The disposable sheets are 100% unbleached parchment paper with no dyes or chemicals, so they won't tint or flavor what you're baking. The four reusable mats are fiberglass coated with Teflon and BPA- and PFOA-free. In my opinion, the real selling point is cleanup: non-stick surfaces mean cookie residue and melted chocolate lift off instead of baking onto the tray.
Who should buy it? The Ninja SP151 owner who bakes in batches — cookies, pastries, small pizzas — and wants prep measured in seconds. Who should skip it? Anyone with a different oven brand, since the sizing is specific to the SP151, and anyone who prefers reusable hardware over paper. Also respect the limits: 450°F for the parchment, 500°F for the mats, no preheating with paper in the oven, and always enough food on the liner so it doesn't touch the heating element. The mats want a rinse before first use.
Ketofa takes the opposite approach: instead of something you throw away, this is a complete replacement kit you keep. It includes an air fryer basket, a baking pan, a wire rack and a pair of silicone food tongs — the three pieces you actually lose, bend or wear out on a French door air fryer. The set measures 12.3 by 12.3 inches and is made from food-grade stainless steel, chosen for stable support that helps reduce bending and warping over daily use.
The compatibility is the first thing to check. It is designed for the Gourmia GTF7655, GTF7460 and GTF7465 French door digital toaster oven air fryer models, and Ketofa states plainly that it does not fit other oven or air fryer brands. Before ordering, compare the sizes against your original parts. If you own one of those Gourmia models, this is a straightforward refresh; if you don't, it isn't the product for you.
In daily use, the stainless steel surfaces are the practical win. They are dishwasher safe, and smooth steel rinses oil, crumbs and sauce away easily — for stuck-on food, soak first and use a soft sponge, avoiding steel wool or abrasive pads. The silicone tongs are a small addition that makes a real difference when pulling hot wings or fries out of the basket. When you're done, the basket, tray and rack stack together, so storage stays compact. Who should buy it? Gourmia French door owners who cook wings, fries, vegetables, toast and pizza regularly and want one kit that covers grilling, baking, air frying, reheating and roasting. Who should skip it? Anyone with a Ninja, a basket-style air fryer, or any oven outside those three Gourmia models.
Side-by-Side: Which Should You Choose?
• Best for baking cookies and pastries → MMH 154PCs. The pre-cut parchment and reusable mats are made for dough, croissants and pie, and cleanup is a matter of tossing a sheet.
• Best for cooking wings, fries and savory food → Ketofa Air Fryer Replacement. The basket, pan and rack are built for grilling, roasting, air frying and reheating daily foods.
• Best for keeping your oven clean with zero scrubbing → MMH 154PCs. Disposable liners catch drips and crumbs; the non-stick mats wipe down.
• Best for a Ninja SP151 owner → MMH 154PCs. Sizing is specific to that oven, and the 154-piece count covers a long run of baking.
• Best for a Gourmia GTF7655, GTF7460 or GTF7465 owner → Ketofa Air Fryer Replacement. It's a direct replacement kit for those exact French door models.
• Best for compact storage → Ketofa Air Fryer Replacement. The basket, tray and rack stack together and take up little cabinet space.
• Best for high-heat flexibility → MMH 154PCs. The reusable mats handle up to 500°F, versus 450°F for the parchment — but keep both away from direct heating-element contact.
• Best for handling hot food safely → Ketofa Air Fryer Replacement. The included silicone tongs are designed for lifting hot items out of the basket.
If you bake cookies in your Ninja SP151 and want the easiest possible cleanup, I would buy the MMH 154PCs. The pre-cut sheets remove the annoying part of parchment — measuring and trimming — and 154 pieces means you're set for a long stretch of baking. The trade-off is that it's consumable and locked to one oven family. If you own a Gourmia GTF7655, GTF7460 or GTF7465, I'd go the other way and pick the Ketofa Air Fryer Replacement instead, because reusable stainless steel hardware that survives daily wings and fries is the smarter long-term buy for that oven. Match the product to your oven first — that decision makes the rest easy.
FAQ
how to air fryer cookies
Line your air fryer tray or basket with a non-stick liner, place the cookie dough with space between each piece, and cook at a moderate temperature until the edges set. With the MMH 154PCs, the pre-cut parchment or reusable mat drops straight in and lifts out for cleanup. The Ketofa basket works too, but cookies can slip through a wire rack, so use the baking pan.
Refrigerated cookie dough goes straight from the package to the liner — no thawing needed. Space the dough portions apart because they spread as they bake, and check early since air fryers run hot. The MMH parchment sheets are sized for the Ninja SP151, so a batch fits without trimming, and the non-stick surface keeps the cookies from sticking.
how to air fry cookies dough
Homemade or refrigerated dough both work, but keep pieces small and evenly sized so they cook at the same rate. Use a liner or pan rather than bare wire, and leave room between cookies for spread. The MMH reusable mats handle up to 500°F, while the disposable parchment is rated to 450°F — either way, don't preheat with paper in the oven and keep the liner away from the heating element.
how to air fry cookies from frozen
Frozen dough pucks need a little more time and a slightly lower temperature so the center thaws before the outside over-browns. Put them on a lined tray or the Ketofa baking pan, leave generous gaps, and flip once if the bottoms are browning faster. Because frozen dough releases moisture, a non-stick liner like the MMH mats makes cleanup much easier than an unlined tray.
