Disposable Foil 8x8 & 9x9 Baking Pans for Cakes, Brownies & Cornbread — Wholesale & OEM
SEPACK manufactures disposable aluminum foil square cake pans — the 8x8 and 9x9 pans that nearly every brownie, cornbread and small-cake recipe is written around. The standard square sizes drop straight into any recipe with no scaling, bake evenly into the corners, and release clean. For square cakes, brownies, cornbread, bars and small casseroles, plain or with lids. Wholesale and private-label, for bakeries, foodservice and home baking.
| Size | Metric | Best For | Lid |
|---|---|---|---|
| 8 x 8 in | ~20 cm | Brownies, small cakes, cornbread | Board / Dome |
| 9 x 9 in | ~23 cm | Square cakes, bars, casseroles | Board / Dome |
| 10 x 10 in | ~25 cm | Larger square bakes | Board / Dome |
| Small / custom | Varies | Retail packs, specific products | Board / Dome |
The 8x8 and 9x9 sizes cover most square-pan recipes. Gauge, size, depth and lid are set per order. For large crowd-size slabs in quarter, half and full sheet, see sheet cake pans; for the full bakeware range, baking pans.
The standard square cake pan sizes are 8 by 8 inches and 9 by 9 inches — the two sizes most brownie, bar and square-cake recipes are written for. Smaller and larger squares are available, but 8x8 and 9x9 cover the great majority of recipes. Custom sizes are made to order.
A wide range — square and bar cakes, brownies and blondies, cornbread, bar cookies, crumbles and small casseroles. The square pan is the everyday baking pan that handles most things baked in a single layer and cut into pieces, which is why most kitchens reach for it first.
Yes. The straight square sides and corners cut into neat, even squares and bars, so a pan of brownies or cornbread divides into equal portions with clean edges. A sloped or round pan cannot portion into squares the same way.
A square cake pan is the standard single-batch 8x8 or 9x9 size for home and small-batch baking; a sheet cake pan is a large quarter, half or full sheet for crowd-size slabs. The square makes one batch of brownies or a small cake; the sheet feeds an event. See sheet cake pans for the large sizes.
You can, but the bake comes out thinner and cooks a little faster, since a 9x9 has more area than an 8x8 — check it a few minutes early. For the same thickness, match the pan to the recipe. Both sizes take board and dome lids for transport and retail; see containers with lids.
Yes. Foil square pans are food-grade aluminum and 100% recyclable. They meet FDA and EU food-contact rules, and the factory holds FDA, BRC, ISO, SGS, Kosher and BSCI certification.
Minimum order depends on size, depth, gauge and lid, with custom sizes and private label following a sample-and-approval flow before bulk. Send the sizes and volume, and we will confirm the right MOQ and lead time.
The square pan is the most-reached-for shape in everyday baking. It is the size brownie, cornbread and small-cake recipes are written around, and the shape that cuts into neat squares. The foil version does all of that disposably, so a kitchen bakes and sells a square cake or a tray of brownies and never washes the pan. This guide covers the standard sizes, what the pan bakes, and how it differs from a sheet or round pan.
Two sizes define the square pan, and they are the two most recipes assume. The 8x8, around 20 centimeters, is the classic brownie and small-cake size; the 9x9, around 23 centimeters, is slightly larger for a bigger cake or a fuller bar. The difference is small but real — a recipe written for an 8x8 baked in a 9x9 comes out thinner and bakes faster. Because nearly every square-pan recipe calls for one of these two, a kitchen that carries both covers almost everything.
The square is the bake-anything pan. Brownies and blondies are its signature, but it also makes square and bar cakes, cornbread, bar cookies, fruit crumbles, bread puddings and small casseroles — anything baked in a single layer and served in pieces. That versatility is why it is the first pan most home bakers own and a staple in any foodservice kitchen. One foil square handles a whole category of single-layer bakes and cut desserts.
The reason the shape matters is the cut. A square pan with straight sides and corners divides into a tidy grid of equal squares or bars, each with clean edges — important for brownies, bars and anything sold or served by the piece. A round or sloped pan cannot do this; it forces irregular pieces and wasted edges. The straight foil walls give the outer row a clean edge, so the whole pan portions evenly with no trimming.
Three shapes cover most cut bakes, and they scale differently. A square pan is the single-batch size — an 8x8 or 9x9 that makes one tray of brownies or a small cake. A sheet cake pan is the crowd-size version, a large quarter, half or full sheet that feeds an event. A round pan makes layer cakes and anything not cut into squares. Choosing between them is really choosing the batch size and whether the bake is cut into squares or served round.
A lid turns a square bake into a packaged product. A board lid covers the pan flat for stacking, labeling and retail; a dome lid clears a frosted cake or a tall bake. With the lid, a square cake or a tray of brownies bakes, travels and sells in one pan — the matched lids are on the containers with lids page. For retail, square pans also sell as multipacks under a private label.
Square pans are single-material aluminum and fully recyclable, and recycling aluminum uses a small share of the energy of primary production. Sourced alongside lids and the rest of a foil container program, a bakery’s square-pan line ships on one spec and one consolidated container, food-grade and compliant for North American, European and export markets.
