If it's a regular recipe or a boxed mix, it will likely be a 9x9 pan, which I usually cut into about 9 bars, or a 9x13 pan, which I usually cut into 12 servings. Foodservice recipes usually call for much larger pans and provide many more servings.
I always buy this mix when I bake brownies. I add crushed Oreos to it. I always use 2 boxes in a 13x9 pan and I wish you had instructions for bake time when it's doubled.
For a large gathering, a sheet cake made in a 9 x 13-inch pan will likely yield the most servings. Depending on how you slice the cake, you can expect to get 15 larger pieces of cake or 20 to 40 smaller pieces.
A 13×9-inch pan is basically a 1⁄4 sheet cake. Most cake recipes that are written for two, 8-inch, or 9-inch cake layers will use the same amount of batter. So, in general, you won't need to make any changes there.
A recipe written for a 9” x 13” pan can also be made in two 9” round pans; one 9” round and one 8” round, or two 8” round pans. Baking times may vary due to slightly different depths of batter in the various pan combinations.
But whether the pan's labeling says 13- by 9-inch or 9- by 13-inch, it should have a volume of about 14 cups (or 3.3 liters) and be the right size for most sheet cake or bar cookie recipes.
If it's a regular recipe or a boxed mix, it will likely be a 9x9 pan, which I usually cut into about 9 bars, or a 9x13 pan, which I usually cut into 12 servings. Foodservice recipes usually call for much larger pans and provide many more servings.
For a two layer 9x13 aka quarter sheet, you will get 48 (1x2x4high) industry standard size servings. Party size servings are 2x3x2high for single layer, so you get approx 18 servings in a 9x13.
Brownies can be kept at room temperature for up to five days for most brownie types. A cheesecake swirl or frosting or a ganache frosting should not be kept at room temperature. Store brownies in the fridge if they contain add-ins that are normally refrigerated.
Prepare your pans
Here are some guidelines: One 9” x 13” cake, two 9” round cake layers, or three 8” round layers all make about 24 standard cupcakes.
You're looking for recipes that make about 6 cups of batter — this amount fits perfectly into a 9” x 13” pan. Keep in mind, not all cake recipes can be seamlessly converted to a sheet cake. Skip recipes that don't use a mixing method of creaming, blending, or the paste method.
For a rectangle, simply take the measurements of the long side and the short side of a rectangular one and multiply them, i.e. 9x13=117 square inches. What is this? From this you can see that you can substitute two 8” pans for the 9”x13” one as 2x64 = 128 square inches which is close enough.
A 9x13 inch sheet cake is a standard size that can serve a varying number of people depending on the size of the slices. Generally, a 9x13 inch sheet cake can serve around 18 to 24 people if the slices are cut to a size of about 2x2 inches or slightly larger.
The typical size for a brownie pan is 8” x 8”, though their depths can range significantly. That said, that's certainly not the only size pan you can use to make brownies, especially if you tend to cook up double batches.
One box mix is enough for a 9x13 cake, if you put both in together it might overflow the sides. If the boxes each say you can bake them in an 8" square pan, you can put both cakes in one 9X13.
Most brownie mixes can be used for either size. The 8x8 will be thicker and fudgier. The 9x13 will be thinner and drier.
It's baked in a standard 9-by-13-inch cake pan. This is a perfect size for parties, and you can expect to get between 12 and 20 slices from a single cake. There are three standard ways you can slice this cake: For 12 Slices: Cut the short side into three equal parts and the long side into four equal parts.

How many brownies will a quarter of weed make? It depends on how strong you want your brownies to be. Using the full quarter will give you just over one batch of brownies (considering you're using an 8x8-inch pan). But for a more mild dose, you may want to start with an eighth of weed.
Size. Pans for making brownies are usually square (8 x 8 inches or 9 x 9 inches) or rectangular (9 x 13 inches), so most recipes are written for use in those sizes. Round cake pans can also be used, and pans for individual mini brownies are available too.
There is no significant difference between a 13- by 9-inch cake pan and a 9- by 13-inch cake pan. They are the same thing. Yes, you read that correctly. For example, pans made by different manufacturers may vary slightly by depth—two inches versus 2¼ inches.
A recipe that makes two 8" round layers will convert into around 18 standard cupcakes, while a 9x13" cake recipe might make up to 36.
Almost exactly double the volume of the 8x8, the 5.3 QT capacity 9x13 rectangular baking dish is more commonly deployed for savory dishes like stuffing, big batch desserts like peach cobbler and blueberry pound cake, or sticky buns.
