I need a good non dairy cake recipe that will stack well for a wedding cake.  l also need a good frosting that can go under fondant.  any suggested recipes would be very appreciated!!!

You can substitute almond, rice or coconut milk for cows milk and soy pudding/yogurt for sour cream to make a dense pound cake in almost any cake. I make cooked flour frosting, and I use almond milk instead of cow's milk in the recipe. Recipe posted below. Follow instructions...no fail. I add 1 cup of icing sugar and a tablespoon if meringue powder...helps ucing crust and pipe.

@jchuck  you forgot about a butter substitute. I don't know about a butter substitute in icing except to use vegetable shortening in an American Butter Cream. Try Indydebi's recipe on here: http://www.cakecentral.com/recipe/6992/indydebis-crisco-based-buttercream-icing You could ask her what to sub for the Dream Whip (has dairy in it).

But a general ABC is: 2 cups fat to 2 pounds of powdered sugar. As for liquid, start with 1/4 cup and go from there. I usually add 1 tablespoon of flavoring to that amount. Will that hold up under fondant? I don't know, but it's a place to start!

For cake, there are vegan baking sticks usually at your local grocery store. You can also usually substitute butter with vegetable shortening in cakes as long as you make up the water difference (shortening has less water than butter). It will usually say on the package how to sub it out.

Yes, your correct craftybanana2 

I substitute shortening and add some butter flavour extract to offset any greasiness. The icing is still light, tasty and easy to pipe.
