    Cake pan- 8 inch square v. 8 inch round?

    I want to make the delicious Devil's Food Snack cake for DD's birthday. The recipe calls for an 8 inch square pan, but it would be more festive in a round pan. Will that work? SHould I use a 9 inch round?

    You can use an 8" round, but if you use a 9" the batter will spread more and the cake won't be as high. You can do it though, just check the baking time since it will bake more quickly than with the 8" pan.

    use the 9-inch...

    the area of the 8-inch square pan is 8x8=64.

    the area of the 8-inch round is pi r-squared= 3.14 x 4 x 4 = 48

    the area of the 9-inch round is pi r-squared= 3.14 x 4.5 x 4.5 = 63

    so the 9-inch round would be much closer in area to the 8-inch square.
    (these calculations are approximate)

    I guess I should have paid more attention in math class. Apparently it does have real life applications!

    Actually I was thinking OMG, MATH on a Saturday morning.
    The best sound is that of someone laughing in their sleep.

    Thanks-- I knew the square would be bigger than the round, but I didn't know how to do the math!!

    Here's some helpful information I posted in a thread last week:

    For those of us who are mathematically challenged, here's some information from Cook's Tiptionary:

    There are times when most cooks don't have the size pan called for a recipe. Substitutions can be made, but it's important to remember that baking times will need to be adjusted when pan sizes are changed.

    To measure the volume of a pan or dish, fill it with water, then measure the liquid. The dimensions of a pan are measured from inside edge to inside edge. Measure the depth by standing the ruler in teh pan and checking the distance to the rim (don't slant the ruler, as with a pie pan).

    Once you know the volume or dimensions, mark the measurements right on the outside bottom of the pan. Scratch the information into metal pans; use a waterproof marking pen on glass or ceramic pans.

    The following ... will help determine substitutions of pans of similar sizes. Otherwise, if a recipe calls for a 8-inch square baking pan (which has a 6-cup volume), you can see ... that a 9-inch round cake pan holds approximately the same volume.

    1/8 cup
    1 3/4" by 3/4" mini muffin cup

    1/4 cup
    2 3/4" by 1 1/8 " muffin cup

    1/2 (scant) cup
    2 3/4 " by 1 3/8" muffin cup

    5/8 cup
    3" by 1 1/4" giant muffin cup

    4 cups
    8" by 1 1/2" pie
    8" by 1 1/2" round cake

    5 cups
    9" by 1 1/2" pie

    6 cups
    8" by 2" round cake
    9" by 1 1/2" round cake
    8" by 8" by 1 1/2" square
    11" by 7" by 2" rectangular
    7 1/2" by 3" Bundt
    8 1/2" by 4 1/2" by 2 1/2" loaf

    8 cups
    9" by 5" by 3" loaf
    9" by 2" pie (deep dish)
    9" by 2" round cake
    8" by 8" by 2" square
    9" by 9" by 1 1/2" square

    9 cups
    9" by 3" Bundt
    8" by 3" tube

    10 cups
    9" by 9" by 2" square
    9 1/2" by 2 1/2" springform

    11 cups
    10" by 2" round cake

    12 cups
    10" by 3 1/2" Bundt
    9" by 3" tube
    10" by 2 1/2" springform

    15 cups
    13" by 9" by 2" rectangular

    16 cups
    10" by 4" tube

    ...and as someone pointed out, you may have to also adjust baking times if the pans are made of different materials.
