This WASC cake recipe is a tender and moist cake that is perfect for white wedding cakes. It's firm enough to stack and cover in fondant but if you're looking for something to carve, you might want to try my white cake recipe.
What does WASC stand for?
WASC stands for white almond sour cream cake. WASC cake recipe has been used for years and adapted many times. I made this recipe many years ago back after reading a thread on Cake Central before I knew how to bake a cake from scratch. The funny thing is by adding all these ingredients, you're basically making a cake from scratch! The only thing you don't have to worry about is the mixing method which can be tricky at first but is easy enough to learn with a couple of tries.
The good thing about WASC is that it's easy to make, is fairly mistake-proof and tastes pretty good and is an easy way to make a boxed cake taste more like a scratch cake recipe.
WASC cake is a tender cake and needs to be fully cooled before you ice it with buttercream.
What is the best box mix to use for WASC?
I prefer Duncan Hines classic white cake mix. Duncan Hines, in my opinion, has the best tasting box mix to start with.
If you need more information on how to make your first cake, check out my full tutorial. In this tutorial, I show you not only how to make this WASC cake recipe, I also show you how to trim your cake layers, fill your cake evenly with buttercream and create a smooth finish.
Because this doctored mix bakes up sturdy, it works great as the base for my Oreo layer cake when you want to fold chopped cookies right into the batter.

WASC CAKE INSTRUCTIONS
- The instructions for this cake are super easy. Basically, put all the ingredients into a bowl and mix it on medium speed for 2 minutes! Voila! Cake batter is ready. Pour batter into two prepared 8" pans and bake at 350ºF for 30-40 minutes or until a toothpick inserted comes out clean. It's ok to bake your cakes for longer if you're using larger pans.

I am making my firstborn wedding cake for a work friend whose whole wedding plans are shot due to covid. I made a sample and brought it to work for a taste test and some people thought it came from a bakery. Soooooo good! Thank you for sharing!

I love this recipe. I use it as my go to when I’m in a need dessert quick mood. I always make 2 x 1 kg loaf tin cakes, they need 45 mins at 170C

I had a recipe very similar to this one in the 90's....I got it from a coworker when I lived in Atlanta. It was soooo good, and I had no control over eating it, I tossed the recipe. I had given the recipe to my mother but did not find it in her books that I have....so I've been hunting and hunting.
I made it this morning. It is close enough to be that recipe!!! I baked it in a Bundt pan at 325 as my pan is dark. (note to self, get a light colored pan) BTW, the batter is yummy too.

SOS. The doctored cake recipes are great for the multiple bakes I do for a local nonprofit. The chocolate is perfect. However, the WASC and the strawberry both shrink when I use the recipe for cupcakes (but not for cakes). When I pull the cupcakes out of the oven they are good form but after 5-10 minutes they become small, dense, flat-topped cupcakes. They are so small that little room is left on the top for decorating which is a priority for the nonprofit bakes. I have made them multiple times; summer and winter; oven is calibrated; etc. Any ideas of how I can fix this dilemma.

This recipe has not worked well for me for cupcakes either.

OMG the cake was deeeeelicious!! My family loved it. I used a cream cheese whipped cream frosting recipe I have and it pair perfectly with the cake.

I cooked this cake for the ladies at work using all butter for the buttercream icing. It was HUGE hit and it was gone in 2 days even though I had cooked it in 9inch pans and made a 3 layer cake. I will use this recipe for an up coming baby shower since it was such a crowd pleaser!
Treva j Dixon says
In the recipe you say 350 degree what type of oven. I have a convection oven is it still 350 or 325. thank you
Elizabeth Marek says
I have a conventional oven

Hi Liz!
This cake was amazing flavor wise.
I normally bake from scratch, so I am used to slightly more structured (but not dense) cakes. I came across a problem, I followed the recipe exactly, same box mix and everything, used 3, 6x2” rounds as you specify, and stacked, but found it was still too soft for stacking, even just three layers. Even fully cooled, the edges started cracking and the whole cake started tilting because of the cracking edges. Thankfully the cake was for myself, but is there any way to make this more stable and less soft? The crumb structure was pretty loose and I still had large air bubbles in the baked layers even after dropping the pans on the counter many times. I’d really love to try this recipe again, but it’s not stack-able:( Any advice you have would be greatly appreciated! I really love the simplicity and taste of this recipe and would love for the structure to work out!
Elizabeth Marek says
I stack cakes when they are chilled, not room temperature. That helps them hold their shape while you are handling them. I have stacked this cake many times.
Beverly says
This is a wonderful recipe!! I live above 5,000 feet, though...couldn't see anything in comments on altitude adjustment...so I baked a 12 inch layer and it fell just a little, but would require some leveling with a knife. I have now baked many perfect layers by doing this:
Add an extra 1/4 cup milk
Remove 2 tbsp. sugar
Everything else is followed as written in the recipe. The batter is quite thick, so be sure you make the batter very level. I have baked 8 layers for a wedding cake and all of them are perfectly flat! Thank you for this great recipe!!!

Elizabeth Marek says
Yes you can. 1 egg white = 1 ounce.
