If you want a flexible, reusable liner set that handles muffins, eggs and small-batch baking in almost any appliance, choose IPOW 24; if you need a dedicated six-cup pan built specifically to fit a toaster oven and turn out evenly shaped muffins, choose casaWare Toaster Oven 6.
• IPOW 24 — biggest strength: 24 reusable silicone cups in two shapes (12 round, 12 rectangular) that go from oven to microwave to freezer to dishwasher, with a temperature range of -40°F to 446°F.
• IPOW 24 — biggest trade-off: These are individual flexible liners, not a rigid pan, so they need a baking sheet or muffin tin underneath for support and they won't hold a fixed six-cup grid shape.
• casaWare Toaster Oven 6 — biggest strength: A 10.5 x 7.125 x 1-inch carbon steel pan sized to fit toaster ovens as well as full-size ovens, with a ceramic non-stick coating rated to 450°F.
• casaWare Toaster Oven 6 — biggest trade-off: Hand washing is recommended and it should not be immersed in water or used in the microwave, so cleanup is more hands-on than the silicone set.
• Who each pick is for: IPOW 24 suits anyone who bakes in small batches across different appliances and wants zero-waste liners; casaWare Toaster Oven 6 suits the toaster-oven baker who wants a real muffin pan that fits the cavity.
IPOW 24 is a 24-piece set of reusable silicone baking cups — 12 round and 12 rectangular — made from food-grade silicone with no chemical coating, no paint, no fillers and no BPA. That construction matters for everyday baking: there's nothing to rust, nothing to hand dry, and nothing to scrub hard, because the non-stick behavior comes from the silicone itself rather than an applied coating that can wear through.
The temperature range is the headline spec. These cups tolerate -40°F up to 446°F without breaking, melting or releasing anything unwanted, and they're microwave, oven, freezer and dishwasher safe. In practice that means one product covers muffin batter in the oven, scrambled eggs in the microwave, and frozen treats in the freezer — the whole loop, with a dishwasher run at the end. The 24-count package (2 x 4 x 2 inches, standard size) is also enough to fill a standard muffin tin plus have spares, or to line a sheet pan for a batch of egg bites.
Who should buy it: anyone who wants to stop buying disposable paper cups, bakes in small or mixed batches, wants both round and rectangular shapes for different foods, and values dishwasher-safe cleanup above all. The rectangular cups also double as snack sorters or lunchbox dividers, which is a genuinely useful second life.
casaWare Toaster Oven 6: Who It's For
casaWare Toaster Oven 6 is a single six-cup muffin pan in a Silver Granite finish, measuring 10.5 x 7.125 x 1 inch. The size is the entire point: it's designed to work in both toaster ovens and conventional ovens, so if your toaster oven is your main baking appliance, this pan is built for that cavity rather than adapted to it.
The build is 0.5 mm carbon steel with a double-coated ceramic surface. casaWare's ceramic non-stick is silicate/glass based, derived from quartz sand, and it's free of cadmium, lead, PFOA, PTFE, PFOS and PFAS — no "forever chemicals" in the coating. The pan is also aluminum free. Heat tolerance is 450°F, and the coating is described as not peeling or blistering at high temperatures, with scratch resistance from the double coat.
Cleanup is where the trade-off lives. The ceramic surface releases food easily — a soft wipe or gentle scrub is usually enough — but hand washing is recommended, you shouldn't immerse it in water, and it's not microwave safe. That's normal for coated carbon steel bakeware, but it's a real difference from a dishwasher-safe silicone cup.
Who should buy it: the toaster-oven baker who wants a proper six-cup pan that fits, bakes evenly shaped muffins and cupcakes, and doesn't mind a quick hand wash. The colored exterior with a cream ceramic interior is also a nicer look than a plain metal tin.
Who should skip it: anyone who wants microwave or freezer flexibility, anyone who refuses to hand wash bakeware, or anyone who needs more than six cups at a time.
Side-by-Side: Which Should You Choose?
• Best for appliance flexibility → IPOW 24. Oven, microwave, freezer and dishwasher safe, from -40°F to 446°F.
• Best for cleanup convenience → IPOW 24. Fully dishwasher safe with no coating to protect.
• Best for even, structured muffins → casaWare Toaster Oven 6. A rigid six-cup carbon steel pan holds shape and spacing in the oven.
• Best for batch size → IPOW 24. 24 cups versus six cavities.
• Best for a permanent, single-purpose pan → casaWare Toaster Oven 6. One durable tool you reach for every time you bake muffins.
• Best for eggs, snacks and lunchbox use → IPOW 24. The round and rectangular cups handle eggs, sorting and dividers, not just baking.
• Best for high-heat baking without a coating worry → casaWare Toaster Oven 6. Ceramic coating rated to 450°F with no peel or blistering, and free of PFAS, PFOA, PTFE and lead.
In my opinion, IPOW 24 is the better buy for most people, because it does more jobs in more appliances and cleanup is a dishwasher run. But if your toaster oven is your primary oven and you want one pan that fits it properly and turns out six evenly shaped muffins, I'd buy the casaWare Toaster Oven 6 instead. Match it to how you actually bake, not to how many pieces come in the box.

how to air fry english muffins
Split the muffin and place the halves cut-side up in the air fryer basket in a single layer. Air fry at around 350–375°F for 3–5 minutes until the edges crisp and the center is warm. If you're using a silicone liner like the IPOW cups to hold toppings, remember silicone is oven and microwave safe but you should follow your air fryer's guidance on accessories.
how to air fry english muffin pizzas
Top each split half with sauce, cheese and your toppings, then air fry at about 350–375°F for 4–6 minutes, until the cheese melts and the edges brown. Keep them in one layer so the tops crisp instead of steaming. A rigid pan like the casaWare six-cup pan is for baking batter, not for air frying, so use the basket directly for this.
how to make air fryer english muffin pizzas
Start with split english muffins, spread a thin layer of sauce so they don't get soggy, add cheese and light toppings, and air fry until the cheese bubbles. Thin toppings cook faster and more evenly than heavy, wet ones. Build them on a plate first, then move them to the basket.
how long to air fryer english muffin pizzas
Roughly 4–6 minutes at 350–375°F for a standard split muffin, depending on your air fryer and how loaded the toppings are. Check at 4 minutes — cheese melts fast and the muffin edges can go from golden to dark quickly. Add a minute at a time if needed.
