• uxcell 18pcs — biggest strength: 18 identical yellow flower cups at 2.75 inch open diameter and 1.2 inch height, rated from -40°F to 446°F and safe in the dishwasher, fridge, freezer, microwave and air fryer.
• uxcell 18pcs — biggest trade-off: It is a single color and a single shape, and the count is 18, so a big baking session means working in batches.
• Mirenlife Reusable Silicone Baking — biggest strength: 36 cups in 6 flower shapes and 6 colors, slightly larger at 2.95 inch upper diameter and 1.38 inch deep, BPA and lead free, same -40°F to 446°F range and dishwasher safe.
• Mirenlife Reusable Silicone Baking — biggest trade-off: The larger diameter can be a snug fit in a small air fryer basket, and the deeper cup means a slightly bigger portion per cup.
• Who uxcell 18pcs is for: Anyone who wants one consistent, repeatable size for muffins, tarts and frozen prep, with no decision-making about which shape to grab.
• Who Mirenlife Reusable Silicone Baking is for: Families, crafters and hosts who want volume, variety and a second life for the molds outside the oven.
The uxcell set is built around consistency. You get 18 silicone baking cups, all the same yellow flower shape, all measuring 7 cm / 2.75 inch across the open top, 5.5 cm / 2.2 inch at the base, and 3 cm / 1.2 inch tall. That uniformity is the whole point: every muffin, tart or dessert cup comes out the same size, so a batch looks like a batch instead of a mixed bag. The silicone is described as sturdy and flexible with no smells, no leaking dyes and no chemical coatings, which matters if you are baking for other people and don't want a liner that stains or smells like the last thing you cooked.
The temperature range is the practical headline here: -40°F to 446°F (-40°C to 230°C). That single spec covers the dishwasher, refrigerator, freezer, microwave and air fryer, so the same cup can go from a freezer stash of pre-portioned batter straight into the air fryer without a swap. The cups are non-stick and easy to release, and the instructions are refreshingly simple — a light spray of oil, set the liner on a cookie sheet, fill, bake, pop the treat out, then rinse with soapy water or run it through the dishwasher.
In my opinion, this is the set for someone who treats silicone liners as a utility, not a decoration. If you bake muffins most weekends, portion out frozen desserts, or want a dedicated air fryer muffin cup you don't have to hunt for, 18 identical cups in one size is genuinely easier to manage than a mixed set. Skip it if you want variety on the plate, if you bake for a crowd bigger than 18 at a time, or if you were hoping to use the molds for soap, crayons or bath bombs — the shape and color here are fixed, and the sheet doesn't position it as a craft mold.
Mirenlife goes the other direction: more of everything. The pack contains 36 cups — 6 unique flower shapes across 6 vibrant colors — each about 2.95 inch (7.5 cm) at the upper diameter and 1.38 inch (3.5 cm) deep. Compared with uxcell, that's a slightly wider and noticeably deeper cup, which means a bit more batter per muffin and a slightly more generous single-serve portion. The material is premium food-grade silicone that's BPA and lead free, and the temperature range matches uxcell exactly: -40°F to 446°F, safe in ovens, microwaves, refrigerators and air fryers, and dishwasher friendly.
Where this set separates itself is range of use. Beyond cupcakes, muffins, chocolates, truffles, pastries, pudding, egg tarts, jelly and ice cubes, the sheet lists craft applications — soaps, crayons, sidewalk chalk, bath bombs, candles — plus everyday jobs like sorting small items, lunch and snack cups, and food dividers. That's a lot of jobs for one purchase, and it's the reason I'd steer a household with kids toward this set rather than the uxcell one. Six shapes and six colors also make it easy to keep portions straight, and the non-stick surface plus dishwasher compatibility means cleanup is the same rinse-or-toss routine.
The trade-offs are real, though. Thirty-six cups take up more drawer or cabinet space than 18, and if you only ever bake the same muffin, the shape variety becomes novelty rather than function. The larger 2.95 inch diameter is worth measuring against your air fryer basket before you commit — a deeper, wider cup that doesn't sit flat will still bake, but it won't give you the clean, even result you're after. And with six shapes, you lose the visual consistency uxcell gives you: a tray of mixed flowers looks charming, not uniform.
Side-by-Side: Which Should You Choose?
• Best for air fryer muffins → uxcell 18pcs. The 2.75 inch open diameter and 1.2 inch height are a compact, repeatable size that sits predictably in a basket, and the 446°F rating covers air fryer temperatures with room to spare.
• Best for variety and gifting → Mirenlife Reusable Silicone Baking. 6 shapes and 6 colors in one pack make it the more giftable, more playful set.
• Best for uniform, professional-looking batches → uxcell 18pcs. One shape, one color, one size — every cup matches.
• Best for crafts and non-baking uses → Mirenlife Reusable Silicone Baking. Soap, crayons, bath bombs, candles and small-item sorting are all listed uses; uxcell's sheet sticks to baking and frozen prep.
• Best for a single-purpose, low-clutter drawer → uxcell 18pcs. Fewer pieces, one size to store, no sorting.
• Best for snack cups and food dividers → Mirenlife Reusable Silicone Baking. The deeper 1.38 inch cup holds more, which suits lunchbox portions.
• Best for portion control on a single treat → Mirenlife Reusable Silicone Baking. The slightly larger cup is closer to a standard single-serve muffin.
If I were buying one set for air fryer muffins specifically, I'd buy the uxcell 18pcs. The 2.75 inch diameter and 1.2 inch height are the safer fit for a basket, the 446°F rating is more than enough headroom, and 18 identical cups keep a batch looking and baking the same every time. I'd only switch to Mirenlife Reusable Silicone Baking if I wanted 36 cups, six shapes, six colors, or planned to use the molds for crafts and snacks as well as baking. Either way, check the current price on Amazon before you decide — and measure your air fryer basket first.
how to air fryer muffins
Mix your batter, spray the silicone cups lightly with oil, and fill them about two-thirds full so they have room to rise. Set the cups directly in the air fryer basket or on a rack, leaving space between them for air to circulate, and bake at a moderate temperature. Both the uxcell and Mirenlife cups are rated safe for air fryer use from -40°F to 446°F.
how to make air fryer muffins
The main difference from oven baking is airflow, so don't crowd the basket — bake in batches if you have to. Silicone cups like these are non-stick and flexible, so the muffins release cleanly once cooled for a minute. If your basket is small, the 2.75 inch uxcell cups are the easier fit; the 2.95 inch Mirenlife cups need a little more room.
how to air fry english muffins
English muffins are already baked, so an air fryer is mainly for toasting or warming them, not for raw dough. Split them, place them cut-side up in the basket, and heat briefly until the edges crisp. Silicone baking cups aren't needed for this — they're for batter-based muffins, cupcakes and similar treats.
how long to air fry muffins
Timing depends on your batter and your air fryer, so treat any number as a starting point and check early. Small muffins in silicone cups generally finish faster than a full-size tin because the air circulates around each cup. The key variable is fill level — overfilled cups take longer and can dome unevenly, so keep them about two-thirds full.
