I know this is out here somewhere but im not finding..
I need to get 25 servings in a rectangle or square (single layer) cake... What size do I make??? Its for a birthday party ...
Here is a partial chart for 2 layer square cakes. I'm thinking for 25 servings you'll need the 12" square if your doing a single layer. However, this is from Earlene Moore's site and I think her servings are bigger than Wilton's. Someone else may have that info for you.
Square Shape 2 layers
6 inch 12
8 inch 24
9 inch 27
10 inch 40
12 inch 60
Just do the math. Assuming the standard 2x2x2 serving size for 25 pieces .......
Means you'll have to cut the cake in 5 columns by 5 rows (5x5=25). If the pieces of cake are 2" x 2", then the 5 columns x 2" = a 10" cake.
If you cut them in 3x2x2, then the 5 columns would be 3" wide = 15" cake on that side ..... then the 5 rows would be 2" wide = 10" on that side. So that works out to about a 11x15 rectangle.
Sorry, I meant to say the 9" not the 12". But I feel confident that what indydebi told you is right. She has a lot more experience at this than I do.
