The Most Ridiculously Moist Chocolate Cake

I’m never opposed to using a good old-fashioned boxed cake mix from time to time. I treat it just like any other ingredient, and sometimes there really is no substitute. Take my Earthquake Cake, for example. Or, there’s this outrageously moist, positively irresistible, completely ridiculous chocolate cake.

The texture of this chocolate cake is so soft and decadent, made with a cake mix, pudding mix, sour cream, and lots of chocolate chips. This is the perfect little chocolate bundt cake to take to any party, or even whip up on a weeknight. It’s that easy. 

Some would say this is too much chocolate cake. And to them, I say, that’s the point! It wouldn’t be ridiculous if this cake wasn’t completely over the top in all the best ways possible.

What Makes This the BEST Chocolate Cake?

I cannot wait for you to try this ridiculous chocolate cake. Just look at that insanely moist crumb! It is hands down one of the best chocolate cake recipes I’ve ever made. And in case the photos aren’t enough to convince you, here’s why:

  • Out-of-this-world chocolatey. I don’t think any chocolate cake rivals the level of rich, fudgy chocolate flavor and soft, melt-in-your-mouth texture of this ridiculous cake.
  • So easy to make. Dare I say, ridiculously easy. There is a time and place for “from scratch” cakes, but not today. This recipe uses store-bought chocolate cake mix and a handful of other ingredients that you dump and mix.
  • One bowl. The chocolate cake batter comes together in a single bowl, for easy clean-up.
The ingredients for ridiculous chocolate cake.

What You’ll Need

The name of the game here is moisture. All the ingredients layered together make the most absolutely ridiculous moist and decadent chocolate cake. Below you’ll find a quick overview, with the full ingredient amounts available in the recipe card:

For the Chocolate Cake

  • Chocolate Cake Mix: You can use your favorite box of chocolate cake mix whether it’s regular Duncan Hines chocolate cake, devil’s food, triple chocolate, German chocolate cake, or another kind.
  • Chocolate Pudding: Instant chocolate pudding mix adds even more flavor to the cake while keeping the texture super soft. Some cake mixes have pudding already “in the mix.” It might be tempting to omit the pudding and use cake mix with it already added, but adding your own pudding mix separately is just better. Trust me.
  • Sour Cream: Another secret to the best moist chocolate cake is sour cream. I go all out and chuck in the whole container. Ridiculous? Exactly. If you don’t have sour cream, you can use equal parts plain Greek yogurt instead.
  • Eggs: For richness and structure.
  • Oil: This cake replaces butter with vegetable oil for added moisture that doesn’t weigh down the crumb.
  • Chocolate Chips: I up the chocolate factor in this cake recipe with semi-sweet chocolate chips.

For the Frosting

  • Butter: I recommend unsalted butter, brought to room temperature so that it’s easier to combine. 
  • Cocoa Powder: Use high-quality unsweetened cocoa powder. Dutch process cocoa powder will yield a darker color and fudgier flavor.
  • Powdered Sugar: Also called confectioner’s sugar, to sweeten the frosting without making it grainy.
  • Vanilla: Pure vanilla extract is best, to enhance the flavor.
  • Heavy Cream: Full-fat heavy whipping cream will make the creamiest frosting.

How to Make Ridiculous Chocolate Bundt Cake

Who’s ready to have their mind and tastebuds blown by a homemade chocolate cake? Cake recipes really don’t get any easier than this:

  • Combine the Ingredients: Add all the cake ingredients to a bowl and mix until smooth. Next, stir in the chocolate chips.
  • Bake: Pour the cake batter into a well-greased bundt pan, then bake at 350ºF for about an hour, until set. Let the cake cool in the pan for a bit before inverting it onto a plate to cool completely before you frost it. If you aren’t frosting the cake (borderline blasphemy, but I’ll let it slide), try it warm and die at how good it is.
  • Make the Frosting: When the cake is cool, whip up a quick batch of chocolate frosting. Begin by creaming together butter, cocoa powder, and powdered sugar, then add the vanilla and cream. Continue to beat until the frosting is thick and creamy.
  • Frost the Cake: Spread the frosting in a generous layer all over the cake. I like to sprinkle a few spare chocolate chips on top at this point, because why not?

Can I Make This Cake In Another Pan?

Absolutely. You can make this chocolate cake recipe in a sheet pan, or as a layer cake, just adjust your bake times accordingly. Here are some quick guidelines:

  • Layer Cake: Divide the batter between two 10-inch round cake pans. Bake at 350ºF for 35-40 minutes, until set. You will also need to scale up the frosting recipe in order to fill the layers.
  • Sheet Cake: Add the batter to a 9×13-inch baking pan and bake at 350ºF for about 25 – 30 minutes.

Tips for Success

Cake mix recipes are basically foolproof, so I just know yours will turn out great. Here are some additional hot tips to ensure your ridiculous chocolate bundt cake is a slice of perfection:

  • Don’t overmix the cake batter. Even cake mix cakes can be overmixed to the point where they turn out dense and tough. Make sure to only mix until the ingredients are just combined, to keep the batter light and airy.
  • Keep the chocolate chips from sinking. The cake batter for this recipe is so thick, the chips hardly sink at all. If you’re concerned about it, however, you can toss your chips in the dry cake mix at the start of the recipe to help keep them dispersed.

More Decorating Ideas and Variations

You honestly could skip the frosting and dust it with a little powdered sugar if you feel so inclined, but since frosting-skipping is against my religion I won’t press the issue.

How to Store Homemade Chocolate Cake

Store your ridiculous chocolate cake in an airtight container or cake saver on the counter for up to 3 days, or for up to 1 week in the fridge. If you do keep it refrigerated, make sure it’s tightly covered and let it come to room temperature again before serving.

Can I Freeze Chocolate Cake?

Yes, but I recommend freezing the bundt cake before it’s frosted. Once the cake is cooled, wrap it tightly in plastic wrap plus a layer of foil, and store it frozen for up to 1 month. Defrost your chocolate bundt cake in the fridge, then frost it as usual.

  1. This is my go to chocolate cake. Everyone loves it! So moist and delicious. I have added a can of cherry pie filling a few times and that’s also a hit. Sometimes I do a cool whip topping if we aren’t wanting such a heavy dessert. No matter how I have made it or topped it, it is always amazing!

  2. This is the easiest and moist cake I think I’ve ever tried. It is so gooie and chocolate.
    I substituted olive oil because I didn’t have any vegetable oil in the cake and I used pet milk instead of cream in the icing. It worked great. I want to try the recipe for the Ridiculous White ca ke too.

  3. I have been making this cake for years. If you are a chocolate lover you will really appreciate it. I substitute real butter for the oil, and make a ganache instead of the frosting. It has always been a hit with my family and friends.

  4. I made this cake and used a 13 x 9 inch pan. There is no way that the cake was done after 20 minutes (the instructions are to bake it for 20 minutes). I baked it for a total of 50 minutes and it was finally done. It was very good!

    1. Sorry it took you longer than expected to bake, but glad it worked out in the end. I have made this in a 9×13 and usually 25 – 30 minutes is perfect, which is noted in the post, but certainly ovens can vary. Just glad you liked it after it was done!

  5. VERY chocolately. My husband also mentioned how rich this cake was with the frosting but i thought it was wonderful. I baked it the first time in a 9×13 pan. Took about 40 minutes. Hands down the best chocolate ever. This time I am using small loaf pans about 3×5 and got 4 small cakes took about 30 minutes. I will leave these unfrosted with maybe a sprinkling of conf sugar on top. We think they taste exactly like the costco chocolate muffins.

    1. Rest of mine is going in the garbage. Did not like it at all!
      I too did it in a 13×9 pan and took longer than 30 minutes. Took closer to 50 min and with semi sweet chips it had a bitter taste.

  6. Made this cake for my husband’s birthday since he LOVES chocolate. This cake was too rich, too sweet, and too dense. My chocolate loving husband even said it was too rich for his sweet tooth.

    1. This cake is ridiculously delish!!! I bake it in cupcakes all the time because there are only 2 of us. I use the same temperature 350 degrees in a convection oven and generally check them at the 30 minute mark.

    This cake is amazing! I made it and everyone loved it Can this recipe be made in something other than the Bundt pan?

  8. Made this cake for daughter 2nd birthday because I needed something easy and it delivered! Everyone loved it. I did have to bake it about 1 hr 5 min to have a skewer come out clean, but I used a silicone Bundt pan on top of a sheet pan because it’s a little flimsy without it. I also did butter cream dolops (plus rainbow sprinkles) on top instead of chocolate instead since I figure the cake was a bit rich. 100 percent would recommend and make again!
