Since most folks answered your other questions, I offer a red velvet cupcake recipe. Unless you have access to a huge commercial mixer, you'll have to make your batter in "home" quantities. You actually don't even need a mixer for this recipe, though. Using oil instead of butter keeps these very moist. Since butter is a solid at room temp and hard as a rock out of the fridge, using butter as your fat will give you a drier mouth feel than using a fat that is liquid at room temp and (mostly) in the fridge.
5 c. AP flour (I weigh flour at 4 oz per cup)
2 c. buttermilk
3 c. sugar
3 c. neutral cooking oil
2 t. baking soda
2 t vinegar
4 T cocoa powder
1 oz. liquid red food color
2 t vanilla
2 t. salt
8 oz. whole egg (5-6 eggs, depending on size)
cream sugar, oil, salt
add eggs, 1 at a time, and food coloring
sift dry together
alternate dry and buttermilk, beginning/ending with dry
add vinegar and vanilla
BO 350 F until done
to make a ton of cream cheese frosting (I am just guessing, since it is usually paired with red velvet cake:
4 pounds butter, cool room temp
4 pounds cream cheese, cool room temp
6 pounds 10X sugar
to taste:
vanilla
salt (necessary)
lemon juice
orange zest
Yum.
Best of luck with the wedding. Them's a whole bunch o' cupcakes
