Making a Sheet Cake

I am looking for a recipe for an extra large sheet cake (using box cake mix). I'm planning a large graduation party for my son. I have a large foil pan. It's called "full size" and measures 20x12 inches. I want to make the cake with box mix. Will this work? How many boxes of cake mix will I need? Also, they have a shallow pan and deep pan, so should I use the shallow pan?

You will need 2 cake mixes, for the bigger pan.

Either pan will work fine, as craftyme said just use two cake mixes for the large pan and one for the smaller one. If you use a recipe instead of a box mix use one of your recipe for the same amount as one box mix. Anytime I use cake mixes and am going to decorate them I freeze the cake before freezing even if I am not going to remove the cake to decorate, I think it adds moisture to the cake. Also if I am using a less expensive cake mix I add one package of instant pudding to each cake mix, really adds some flavor and moisture, also add an extra teaspoon of vanilla or other extract of choice.


Good luck and have fun.

Easy Cake
1 yellow cake mix -Mix as directed on box and bake on cookie pan with sides at least 1" deep (18x12x1) or ( 17x11x2) Do not use a smaller pan. Bake @ 350 for 20 to 25 min. Cool in pan completely.

Mix 2 small size packages of vanilla instant pudding with 3 cups of cold milk beat well then add 1-8oz pkg softened cream cheese. Beat well (some small lumps of cream cheese will remain) Spread this mixture on cold cake
Drain very very well lg can crushed pineapple and put this over pudding layer. Spread 1 lg container of cool whip over fruit layer. Sprinkle some chopped nuts over cool whip. Good cake for a crowd. serves 30 to 35 people


Different cake mixes & different puddings & different fruit toppings can be used.

Need to know your pans, sizes and best uses, also kind of metal they are made of. is the perfect website to help you.

Quality of cake mixes I find diminishing, so I plan for 1 1/2 boxes per 9x13x2or3 cake recipe needed. The other half of the cake the kids get to eat (put in another pan/dish). I also add 1 tsp per cake mix box of FRESH BAKING POWDER for the best moist, fluffy structured cake. If you are planning lots of frosting or decorating, then you need a heavier structured cake, those with puddings in or pound cake consistency.

I use mostly Air Bake Pans. Go to the website listed above and any question you have will be answered. Just know what kind of ingredients will be used, as taller pans and lighter cakes go together. Pound or pudding cakes need a bigger base as not to be all gluey/sticky and easier not to have raw spots.


Above all, ask your son for color and flavor. My grandchildren's favorite is 1 bowl of choco and 1 bowl of white with added orange food color, orange flavoring. Using smaller 8x8, 9x9 pans, pour a little of the chocolate in and spread around. Pour orange in the center, let spread out on its own.

The chocolate swells and bakes around the orange. Who doesn't like the flavor of blood-orange chocolate candy? Tastes just like it! Can do this with variety of flavors and colors. Make Easter basket cakes a breeze! All 1 container contained. Frost with your favorite cooked/whipped fluffy frosting and decorate.

As a cake decorator, I go by this rule: 9x13, one mix; 12x15, 2 mixes; 12x18, 3 mixes. Each pan is approx. 2 inches deep.


I would feel confident using 3 mixes in your 12x20 pan; probably your shallow pan would measure around 2 inches. That should be just fine.

Good luck! Melinda from MO

You might want to consider renting the cake pan from a cake/candy shop. The foil pan is going to have to be re-enforced, unless you don't plan on taking it out of the pan to ice the entire cake. Another thing to consider is the size of your oven. I have a Wilton 20 x 12 pan and my oven is too small for the pan. There is not enough airflow for the pan, and my cakes burn. My Wilton pan takes 3 boxed mixes. You could also use a 9 x 13 pan that it extra deep, it will take 2 boxed mixes, bake 2 separate cakes, different flavors if you want, and place them side by side and ice as one cake. Good Luck!

I am wanting to make a sheet cake, but not sure what type or size of pan I should use. Any suggestions? Thanks in advance.

Wilton's makes cake pans of all sizes and shapes, including sheet cake pans. You can find them at Michael's, Craftmart, Walmart (sometimes) and other craft or baking supply stores. (10/15/2008)

Making A Sheet Cake

A sheet cake is just the flat, long one. You can get disposable pans or used ones at the local store in the bakery aisle, or your local thrift store.

Here's a great recipe to try.


1) Bake a white, yellow, or pink sheet cake. When it is cool, poke holes in the top all the way to the bottom around the cake about 2" apart, with the handle end of a wooden spoon.

2) Make any flavor Jello, Royal or generic 4 oz., using just the hot water! Pour it evenly over the cake, cover, and chill for 1 hour.

3) When the cake is chilled, cover with whipped cream that you make or get in the tubs. When you cut into it, it's moist, a cool color and flavor, and you don't have to frost it!

NOTE: When you fill the cake pan, lift it up several times and drop it from about 3" from the counter. You will see little bubbles come up from the bottom and eventually burst open at the top. Those are why cakes often come out uneven. Doing this helps a lot. (10/17/2008)

A 13x9x2 pan should do. (10/17/2008)

Bake and place two 9x13 cakes side by side, so the cake measures 18x13. (10/18/2008)

I always have thought a sheet cake was at least a 15" by 13". That is what the bakeries call them. (10/18/2008)

Making A Sheet Cake

In our area a "sheet cake" is one that is baked on a large cookie sheet (15 x 10 1/2), so that when you cut it, it is more like squares or bars than a piece of cake. People use a regular cake recipe, and ice it as usual, but of course, the cake is only about an inch thick. If one was using a cake mix, you would use only one packet, I think. The cookie sheet must be the kind with sides, like you would bake a jelly roll in.

Of course, these other posters are also correct, as cake mixes, and of course most cakes, can be baked in a 8 1/2 x 11 or 9 x 12 cake pan as opposed to baking them in round pans and assembling them into a layer cake.

Pyrex cake pans come in the 8 1/2 x 11 size, and aluminum cake pans come in the larger size of 9 x 12. I prefer the larger aluminum pan, but either is nice. (10/19/2008)
