Chocolate Sour Cream Cake- Doctored Mix

DELICIOUS Chocolate Sour Cream Cake (Doctored Cake Mix) Recipe by! So decadent! This one's a keeper!

Nobody would believe that this decadent chocolate cake all starts with a simple mix!


  • ** For a deeper chocolate taste you can add 1 tablespoon cocoa powder and replace the water with 1 cup hot strong brewed or instant coffee.
  • 1 Devil's Food Cake Mix ( I sift the cake mix, but it is optional)
  • 1 cup all purpose flour
  • 1 cup granulated sugar
  • ¼ teaspoon salt
  • 1 cup sour cream
  • 1 cup water (We usually replace the water with 1 cup of hot brewed or instant coffee, it enhances the chocolate flavor.)
  • 3 whole eggs
  • 2 ½ teaspoons vanilla
  • ½ cup (108g) vegetable oil


  1. In a separate bowl, combine the dry ingredients and stir or whisk to blend. In your mixing bowl, combine sour cream, oil, water, eggs, & flavorings. Add about ½ of the dry ingredients and blend together, then add the rest of the dry ingredients & mix on medium speed for 2 minutes.
  2. Pour into three 8 x 2 inch round pans that have been greased and floured. Bake at 325 degrees for 22-25 minutes or until the middle of cake springs back when touched or a toothpick inserted into the center comes out clean or with just a few crumbs attached.
  3. *This also works well for cupcakes! Bake cupcakes at 350 degrees for 18 to 20 minutes. Remove cupcakes from the pan immediately and cool on a baking rack.

  1. Made your Chocolate Sour Cream from a box cake today. What an awesome recipe. Used instant espresso for coffee and added 1 tablespoon Droste chocolate powder and also used the devils food Duncan Hines cake mix. It was such a hit, everyone thought it was from scratch. I've been asked to be the official dessert maker in our group! This is the third cake recipe I have used from your site and each one has been a hit. Thank you for sharing your website. I especially like the way you put the recipes together, it makes it so easy.

    1. Hi Gloria! Thanks so much for your feedback, so happy to hear that you all enjoyed the recipe! xo

  2. Hi
    I’ve been making your doctored cake mixes for years for our cake decorating kits /parties and they’re always fabulous ! I remember when the cake mixes went from 515 grams to 432 grams but your ratios still worked . Today I bought a few new cases of Betty Crocker mixes and they are now 375 grams !!!!!!!!!!!!!!!!!! Should I now change the ratios of added flour , sugar , sour cream and eggs ?! Thanks so much !

    1. Hi Tammy! I am frustrated by this too! We most often use Duncan Hines and haven't had a chance to experiment with the new version of Betty Crocker mixes. My guess would be that the recipes would still work but just may not go quite as far (which would be most noticeable with cupcakes).

      I've seen others say that they deal with downsized mixes by having extra box mixes on hand that are used just for making up the difference.

  3. What does using sour cream instead of mayo do? Maybe make it sturdier? I read somewhere that the sour cream can slightly alter the taste? And last time I used sour cream it didn't seem as chocolatey. Maybe adding that extra tablespoon of cocoa can help bring it back. I definitely need sturdy since doing a fondant ramen bowl cake. Thanks for any guidance.

    1. Hi Tina- I don't detect sour cream flavor in the cakes (scratch or mix) that call for it. It wouldn't hurt anything though if you would like to add more cocoa! This recipe calls for a cup of sour cream-- our cake mix recipe that calls for mayo uses a much smaller amount. The sour cream cakes are probably just a bit more dense, it adds richness and moisture without thinning the batter, and it also helps to extend the recipe. We hope you enjoy it!
