I am making a 3 tier cake for a reception. I need a good wedding cake recipe which starts with a white cake mix (I already have the mixes). I tried making a WASC cake. It tasted really good but it wasn't dense or moist enough for what I need. Any suggestions would be appreciated.

How dense are you looking for? pound cake dense?
Why are you looking for a dense cake? For stacking?
If it's because of stacking, it's not the cake that needs to be strong, it's your structure. The cake does not support the other tiers of cake, it's your support structure (plates and pillars/dowels) that support the upper tiers of cake.

It needs to be more dense because thats what the person requested. She liked the taste but not the texture of the WASC cake.

I'm thinking she must want a really moist pound cake. Can anyone help?

Sorry, I don't think you can use the cake mixes. The WASC is basically the closest you can get to pound cake using doctored cake mixes. I hope you can return them or use them for another cake.

I suggest Elvis Presley's Favorite Pound Cake

I came across a doctored cake mix recipe that might work:

1 cake mix
1 package instant pudding mix
4 eggs
1/2 cup water
1/2 cup oil

Makes two 8" rounds; bake approximately 40-45 minutes at 350. Comes out dense and moist. HTH

Paula Deen has a VERY moist pound cake recipe on her website. I think she calls it sour cream pound cake. It is delicious!

Good Luck!

But I don't think you can beat Elvis Presley's Favorite:

Thank you so much! All the suggestions look like they might work! For the Elvis Presley's Favorite Pound Cake it says to use a fluted or bundnt pan. I need to use 16, 12, & 8in square pans plus make 3 12x18in sheet cakes for the event. Do you think it would stil work for these pans?
