Most experienced bakers have tried this WASC Cake Recipe at least once in their career, and there is a reason that folks keep coming back to it. It works!
So what is a WASC cake? It is a White Almond Sour Cream cake that is semi-homemade. (Meaning there is a box mix involved!) Bakers love this recipe because it tastes so good, but also holds up very well to decorating and fondant. Not to mention that it is SO open to variation!
How to Make Box Mix Taste Like a Wedding Cake
Making a box mix taste homemade is pretty easy, there are just a few simple ingredients that make it perfect. Be sure to ONLY follow the recipe below when making the cake, do not add the ingredients suggested on the box!
Start by sifting the dry ingredients, then introducing the wet. To ensure that you have success, be sure to use ROOM TEMPERATURE ingredients! This will allow proper incorporation of all the ingredients.

How to Decorate White Almond Sour Cream Cake
Prepare WASC cake recipe below and allow to cool.
Prepare buttercream. (follow the instructions for WHITE buttercream!)
Set one layer of cooled white cake on the cake stand. Cover with 1/2 cup of buttercream. Place other layer on top. Cover cake in a thin crumb coat.
Divide remaining buttercream between pastry bags fitted with #18 and Russian tip.
Starting at the bottom of the cake and moving around the base, pipe out a criss-cross border with the #18 tip. (think heart shape, then overlap) For the next layer, repeat this same motion but in the opposite direction. Do this around the entire base (sides) of the cake.
For the top, simple pipe out the roses with the Russian tip. I started at the outer edge and moved in towards the center of the cake. I tried to pull up and “out” as I released pressure from the piping bag so that the outer roses are leaning out a bit instead of straight up and down.
Chill cake until ready to serve.
PRO TIPS for WASC Cake
I used egg whites and clear vanilla extract to ensure that my cake would be as white as possible.
I also used room temperature ingredients and did not over-mix the batter.
Allow the cake to cool before decorating! I often pop it into the freezer which helps to minimize crumbs.
So how does this cake hold up? Very well! Now only is it stable, but it tastes really fresh and delicious!

This semi-homemade WASC Cake recipe is from Kakeladi on Cake Central.
Should there be butter or oil in this recipe?
Does this need to be adjusted since box cakes have less mix now? They have decreased from 18.25oz to 15.25oz. Thanks for your help!
Hi, I would like to try the WASC cake recipe with a 9×13 pan. Any suggestions?
You certainly can, I just don’t know the exact baking time.
Is this recipe similar to a “bakery” white birthday cake recipe?
will this recipe work well with yellow or strawberry cake mix
I am using this to make my strawberries and cream cake. If it turns out lovely (I suspect it will), I will share pics with you.
