Doctored cake mix chocolate bundt cake made with sour cream and chocolate pudding mix. This is an easy dessert recipe that tastes homemade and a great way to improve boxed cake mix!
Easy Cake Mix Cake with Pudding and Sour Cream
This is a semi homemade or semi from scratch recipe so you still get the great taste of fully homemade cake but without all the work.
In fact, you can make this cake entirely without a mixer or a whisk! I made it by hand using a large spoon and since you only need one bowl to mix everything in, those are the only two things (besides the bundt pan) that you need to dirty.
This cake is super moist, soft, and fluffy, and the chocolate flavor is more pronounced thanks to the addition of chocolate pudding mix.
Ingredients You’ll Need
- 1 cup full-fat sour cream
- 3/4 cup vegetable oil
- 1/2 cup milk
- 4 eggs
- 1 box (15 – 16 ounces / 432 – 492 grams) chocolate cake mix, unprepared
- 1 box (4-serving size) instant chocolate pudding mix, unprepared
Adding these extra ingredients is a good way to make cake mix better! A lot better.
I used Betty Crocker’s Devil’s Food cake mix but you can use Pillsbury, Duncan Hines, or whatever you have on hand.
What does adding Sour Cream to Cake Mix do?
Adding just the right amount of sour cream to cake mix will yield a cake that is richer, more flavorful, and slightly but pleasantly dense.
If you add too little you’ll hardly notice a difference and if you add too much and the cake will be too dense and heavy.
What does adding Pudding to Cake Mix do?
Adding pudding mix to cake mix enhances the flavor, adds moisture, and yields a fluffier texture.
How to make Sour Cream Chocolate Cake with Cake Mix
First, preheat the oven to 325°F. Baking the cake at this temperature prevents the crust from being dry and ensures that the whole cake bakes at the same rate.
Next, grease the bundt pan well with oil or butter. I always use vegetable oil. Be sure to coat the entire surface of the inside of the pan!
Then, mix together all of the ingredients; combine the sour cream, oil, and milk, beat in the eggs, then incorporate the chocolate cake mix and chocolate pudding mix. The batter will be oddly thick but that’s exactly how it’s supposed to be.
Pour the batter into the pan and bake for 40 – 45 minutes.
Let the cake cool in the pan for about 20 minutes before removing. I know that seems long but I find that when you take it out too early, it is more prone to fall apart.
Lastly, top it with your favorite glaze, frosting, or ganache. Or simply dust it with powdered sugar. Thankfully this cake isn’t overly sweet so you can decorate it with whatever you like without worry.
Here’s the vanilla variation! I like this one better.
Sorry, chocolate lovers.

Chocolate Pudding Sour Cream Bundt Cake (Boxed Mix)
Click the stars to rate!
Ingredients
- 1 cup full-fat sour cream
- 3/4 cup vegetable oil
- 1/2 cup milk
- 4 eggs
- 1 box (15 - 16 ounces / 432 – 461 grams) chocolate cake mix, unprepared
- 1 box (4-serving size) instant chocolate pudding mix, unprepared
Instructions
- Preheat oven to 325°F.
- Prepare a 10 – 12 cup (9 – 10 inch) bundt pan by greasing it very well with oil or butter. Set aside.
- In a large bowl combine the sour cream, oil, and milk.
- Beat in the eggs.
- Add the cake mix and pudding mix and gently mix until fully incorporated. Do not overmix.
- Pour the batter into the greased bundt pan. Smooth the top into an even layer.
- Bake for 40 – 45 minutes until a toothpick inserted deeply in the center comes out clean, then again on the opposite side.
- Cool in pan 20 minutes then remove by placing a large plate over the top and flipping it right side up. If cake doesn’t fall out right away, give the pan a few light taps until it does.
- Let cake cool completely for about an hour or at least until no longer piping hot before decorating.
- Top with frosting, glaze, or ganache of choice, or dust with powdered sugar.
Notes
- I used Devil’s Food cake mix for this recipe.
- Can I use low-fat or nonfat sour cream? Low-fat may work but I cannot guarantee that you’ll get the same results and I strongly advise against using nonfat. The fat plays a big role in the taste and texture of the cake. I've only ever used full-fat sour cream for this recipe.
- Can I use butter instead of oil? No! Although the flavor of the butter is really good, it drastically changes the texture of the cake. I have tried it myself with the vanilla version. The butter weighs the cake down and is not as moist as oil.
- My cake mix already has pudding in it. Do I still add the pudding mix? Yes! Do not leave it out!
- Does this cake need to be refrigerated? Yes, however it can be left out for 24 hours. After that, refrigerate immediately.
- How long does it last? About 4 – 5 days.

My favorite is the vanilla too! I love the taste of the pudding in these cakes. Thanks so much for leaving a comment!
I don’t know why this recipe doesn’t have dozens of rave reviews…it’s that good. I’m an old lady who used to only bake from scratch until the COVID shortages hit us in 2020. Then I started using doctored cake mixes so I could continue to bake treats for my grandchildren. I love that this is a 1-bowl recipe using only a whisk or wooden spoon. This cake has the density of a poundcake which is my family’s favorite. Thanks so much for posting this. My family LOVED it.
I’m so sorry for the late reply. I think it doesn’t have dozens of reviews because the pictures look bad ? I need to update them but these will have to do for now. I love that about this recipe too; it’s so quick. That’s really great to hear, Lisa! Thanks so much for the 5-star review.
My family loves this cake. The best chocolate cake ever..
Thank you! I’m happy everyone likes it.
Excellent! I used a Gluten Free cake mix, substituted butter for vegetable oil because that’s what I always do with prepared mixes. It was moist and delicious!
I do that too but I love the moisture you get from the oil with this recipe. Thanks for leaving a comment.
What a terrific cake! So moist and delicious! We added some mini chocoloate chips to it for an added touch (my Mom’s favorite), and everyone swore it was a fully homemade cake! The mini chips were perfect because they spread throughout and don’t all fall to the bottom of the pan.
Will Adding Glaze to Warm cake , make it fall?
I doubt it. As long as it’s mostly cool.
You have my undeniable admiration! I followed your recipe to the letter and when we cut into it the texture and crumb were irresistible. I did bake it for 55 minutes but then, I do have a squirrelly oven! I topped my cake with thick chocolate frosting and a liberal amount of tiny sprinkles. It took only 2 hours for the platter to be ‘clean’. Who knew sour cream could add such richness? ?
Thank you, thank you. But don’t give me all the credit. You executed it perfectly. Bravo. Yes, that’s exactly why I love baking with sour cream!
can you make brownies with this r
Nope, I’m afraid not.
This was delicious! This is a keeper for me 😀
Yay! Thanks so much for the 5-star rating.
Moist cake
Good recipe
I made mine with lemon ,it’s absolutely delicious. One question, mine always falls, how come ? The toothpick comes out clean
My favorite recipe. The best cake I have ever made. I did add 1 teaspoon of vanilla.
