White Velvet Cake

I got this white velvet cake recipe from a friend who also does cakes.  I know it’s from a box, but it is so good. Loads of people have tried this cake, and I have had great response. One reader who commented on Facebook sent me a picture of a wonderful Mickey Mouse cake for her son, and had this to say, “I made my son’s birthday cake with your white velvet cake recipe layered with mocha cake, oh my goodness the white velvet is hands down the best white cake I have ever had! Thanks for the recipe!” You will be glad you tried it too.
I sometimes double the recipe, and the batter half way fills 2 – 8×2″ pans and 2 – 10×2″ pans. That gives me a great 2 tiered cake with enough cake top to level off.
1 box white cake mix
1 cup sugar
1 cup flour
1/8 tsp salt
1 1/3 cups water
3 eggs
1 cup sour cream
1 tsp vanilla
Mix the water,eggs, sour cream, and vanilla with paddle attachment then add the other four ingredients. Beat slowly for 30 seconds and then on high for 2 minutes. Makes about 7 1/2 cups batter to fill two full 8″ rounds.
Bake as directed by box instructions.

    I made this cake for my daughter’s birthday on May 15th. It came our great. I baked it in a 9×13 dish with the wet strips and it came out perfectly even. I have never had that happen. No leveling required. My husband loved the cake and even said he could eat it by itself. I plan to use this recipe from now on. Thanks for sharing.

    May I ask what size cake box.. as in how many grams of mix? I’m in Australia and I am not sure if it is just the standard? the cake look amazing and I’d love to make it but I don’t usually use cake mix,. I make things from scratch :-)

      I know – I generally make things from scratch too, but I love this cake. So many people have tried it and love it, so I just stick with what works. The cake boxes here are 18.25 oz (1 lb 2.25 oz) or 517 g. I hope that’s helpful. Let me know how it turns out.

    Hey Jodi!

    I can’t wait to try this recipe, but I have a couple of questions. Is there no butter or oil in this recipe? Also, what kind of flour is used, cake flour, all-purpose…?

    • says

      Thanks for asking, and I’m so glad you are going to try this recipe. It has not butter or oil. The sour cream provides the fat needed, I guess. I just use all purpose flour. For some of my other cake recipes I use cake flour, but I’ve never needed to try it with this one. I don’t think this cake can disappoint. Let me know how it turns out.

    Hi there! Can you say which kind of box mix you use? I’m hoping to find one that doesn’t have any dairy or egg products already in it. I have a really moist white cake recipe I like, but it has a large crumb and I found it’s not as pretty for layer cakes as one with smaller crumbs, which hold a better, crisper shape (mine kind of crumbles a bit and looks sloppy when you cut it–it’s really a cupcake recipe, and is great for that, but is not . Yours looks pretty great, so I’d love to try it!

      You know, I just buy whatever is on sale. I really have wanted to have a taste test between the different brands because I’d be curious. It’s seemed to taste great no matter which one I’m using. I hope you enjoy.

      I’m so glad you tried it and had success. It really is a great recipe. Your daughter’s party looked fabulous. I’m so happy that my posts were helpful, and I really appreciate you linking back. Thanks so much!

    Hi Jodi,
    I’m in Australia and saw your recipe here and would love to try this recipe to bake a cake for my niece 2nd birthday. For the cake mix we have here generally ask for vegetable oil, do I not need to add any additional ingredients requested on the box but instead just add the additional ingredients you suggested? (In this case, like you mentioned in one of the post, sour cream replaced oil/butter?) Thanks!!

    I made this recipe for my daughter’s first birthday. I made six 8″ rounds – one in each color of the rainbow. I also had some left over for cupcakes (taste testing!) and it is delicious. So glad I found the link on Pinterest. Thanks!

    I made this for our Easter gathering and the cake was delish! I will be making this again for my daughter’s upcoming birthday!

    Your recipe says 1 boxed cake mix, the cake mix i have is betty crocker and it’s 16.25oz. I know betty crocker has downsized from 18.25oz. how many ounces does this recipe call for?

    • says

      So interesting! I just checked the boxes I used, and they are 15.25 oz. I hadn’t paid attention until now. I wonder why there is a discrepancy. My Betty Crocker is 15.25 too. I have both Betty Crocker and Pillsbury. I hope that’s helpful. It’s odd though.

    i’ve used this recipe with a chocolate mix and i added cocoa powder and it worked fine. problem is i can’t remember how much i used. start with 1/4 cup but i wouldn’t go past 1/2 cup. you’d end up with a dry cake.

    • says

      Hey there. Just use the hand mixer and mix it until it is completely combined. It will be fine with what you have. Let me know what you think! It’s funny, my birthday was last week, and my friend made it for me for my birthday. I said, “Wow, this is really good cake.” She said, “I hope so. It’s you’re recipe.” I hope you like it as much as I do.

    Hello there,
    Thank you for all your tips. They are brilliant. I am making a cake for my brothers wedding soon (first wedding cake aaagh ). The top tier is 8 inch but my middle tier is 10 inch. How would I change ingredient quantities for this please

    • says

      Hi! Ooo – a wedding cake. Have fun! I hope it goes really well. I’m actually a pretty bad person to ask about this. I always just double or triple the recipe without adjusting…especially since it is calling for a full box cake in this recipe. Since I freeze cakes and cupcakes, I just freeze the extra for later use. So, for an 8 inch and a 10 inch, I’d triple the recipe. The extra batter I’d throw into cupcake tins or a six inch and freeze. I wish I had better numbers for you so you could be more exact, but I’d just be making it up, and I don’t want to do that – especially since it is a wedding cake. I hope it goes really well. I don’t think you’d be disappointed in this recipe. Thanks!

        Apologies for late reply. I only saw it now. Thank you for your advice. I will give it a go and let you know how I get. Thanks again

    Iam making this mermaid cake for my daughters 6th birthday and found you! I am in NZ and just curious. Do you just use any old cake mix in a box? I thought it had all the ingredients ready inside you just have to add wet mix. Do you still have to add the flour etc that you stated on the recipe above?

    • says

      Hello, Yes – You use any old white cake mix. You then add all the ingredients in the recipe. I know it seems weird and counter-intuitive, but it’s a great cake I’m sure you will enjoy. Let me know how it goes.

    • says

      Thanks so much for linking back. I’m so glad you like this cake. My birthday was in January, and a friend of mine made me a cake. I said, “This is really good cake. I love it.” She said, “Well, you should. It’s your recipe.” Ha! I’m glad you have had so much success.

    I am going to attempt to make the rainbow cake for my daughter’s first birthday and was going to use this recipe. I’ve heard great things about it. However I am confused about the size cake mix needed for the listed ingredients in one comment I see 18.25 and another 15.25 . I bought the 18.25 size are the ingredient amounts listed correct for this cake mix size? Thanks so much I just don’t want to mess it up.

    • says

      Umm…Interesting…I just went and looked at the three box cake mixes I have on hand and they are three different sizes. I had no idea. None of mine are 18.25 oz though. All are smaller. I am not quite sure. I would just go for it. I’ve never really paid attention to the size and have never had problems. If you do try it, will you report back with the results? I really hope it goes well!

    I am going to make this tonight, can’t wait! I’m in Scotland and our box cake mix are 230g, so I am going to try using 2 packs.

    • says

      I’m not quite sure. I would love to know the results if you tried it. I can say, I tried to do a chocolate box cake with the same additions, and it wasn’t as good. It wasn’t horrible, but I have better chocolate cake recipes. Let me know if you try t and what you think.

    FYI- unless Duncan Hines and Betty Crocker ships different size boxes of cake mixes to different areas of the U.S., the amount in Duncan Hines now is 16.25 and Betty Crocker is 15.25. I have had to recalculate all the ingredients in my cake recipes that use a box mix as the base.

    • says

      Oh no! I switch off depending on what’s on sale. I know I just made a Pillsbury that is 15.25, and it turned out greats. Thanks for the heads up. This is great to know!

    Made this for the first time and frosted it with whipped cream and coconut and the men in our family went completely crazy over it. They thought it was made from scratch :) Thanks for sharing this! can’t wait to make some cupcakes with this recipe.

    • says

      So much fun to hear your reports. I’m glad you love it as much as we do. My husband was never really a cake guy, but all of that has changed now. Enjoy those cupcakes!

    I am planning to make a rainbow cake and wondering how much food coloring did you put in each 8in. pan? Did the colors come out vibrant?

    • says

      I used gel food coloring. I’m not sure how much I added. I would definitely just keep adding until it looks vibrant enough for you. I am sorry I don’t have more details than that. I hope it goes well.
