My most decadent bundt cake yet, this chocolate bundt cake is dense, moist, rich, and covered in a luscious chocolate fudge frosting. Recipe includes a how-to video!
One Bowl Chocolate Bliss
There are few things I enjoy quite as much as taking a dessert I already love and transforming it into an even more decadent, chocolate version of itself. First was my chocolate cake, then my chocolate cheesecake and chocolate rolls, and today it’s this rich, decadent chocolate bundt cake.
It’s the evil twin to classic bundt cake, dark and mysterious, cloaked with a glossy fudge cape and pierced with melty pops of chocolate chips. It’s deliriously good, perfectly dense but still soft and moist.
And it’s made in one bowl (excluding the frosting, I hope that’s obvious 😉). I literally don’t know what more you could as for.
What You Need
- Flour. Make sure you use all-purpose (plain) flour and do not use self-rising flour or you’ll have quite a mess in your oven.
- Cocoa powder. I use and recommend using unsweetened natural cocoa powder. I have not tried this recipe with Dutch processed or dark cocoa.
- Baking powder & baking soda help give the cake some lift.
- Salt & vanilla extract enhance the flavors of the cake.
- Very hot coffee or hot water. A HOT liquid is essential to “bloom” the cocoa powder and give it a rich chocolatey flavor. Either will work well, but using coffee will enhance the chocolate flavor even more.
- Sugar. I use a blend of granulated and brown sugar (which adds flavor and moisture to the cake).
- Eggs. This recipe uses half the number of eggs that my classic bundt cake uses.
- Sour cream adds moisture, flavor, and tenderness to this cake.
- Butter & oil. A blend of butter and oil gives the cake the right balance of flavor and moisture, without making it dry! I use this technique in many of my cake recipes (like my red velvet cake!)
Tip: Instead of mini chocolate chips you can finely chop a 4 oz chocolate bar by mincing it as you would mince garlic. This leaves melty chocolate flecks throughout the whole cake.

Low Maintenance Cake Batter
This batter for this cake is simple to make and can be made in a single bowl. It’s simple, and unlike many, many cake recipes it’s quite difficult to over-mix.
I’m not saying it’s impossible so don’t go crazy with your Kitchenaid and walk away with it on speed eight while you make a phone call to the IRS, but the batter is… durable. The cake is slightly more dense than your average cake by design (as a good bundt cake should be), made with melted butter and oil rather than creaming together the butter and sugar.
You need to mix thoroughly and can make the whole thing with an electric mixer (rather than worrying about folding together wet and dry ingredients by hand like you must with my vanilla cake).
How could any chocolate bundt cake be complete without a fudgy crown of glossy chocolate icing? While I have my frosting of choice, I’m leaving you with a few options:
- Use the icing I include in the recipe, which is the same irresistible fudge glaze that I use on my hot milk cake.
- Use my chocolate ganache, which is a common bundt cake icing and is a bit darker in flavor.
- Or you can be vanilla and just dust the cake with powdered sugar, just don’t actually tell me that you skipped more chocolate for that it or I might just judge you (just a tiny bit).
I had a battle with my perfectionism while filming the icing portion of this in today’s video (in the recipe card). It was taking forever for it to cool to be thick enough to pour (the lights we use to film are hot!) so I set it aside to do something else and when I came back it had cooled too much and was thick like my chocolate frosting. If this happens to you, you can pop the icing in the microwave for a few seconds at a time until it returns to the proper consistency, but I tried to just roll with it (like I said, those lights are hot and I was tired!) so my icing in my video looks a little less than perfect!
Frequently Asked Questions
While cake flour could work when substituted properly, I don’t recommend experimenting with any other flour. Using self-rising flour is a big no-no and will cause your cake to overflow all over your oven.
Cornstarch helps to make the cake more tender. If you don’t have it you can leave it out.
Yes! Wrap tightly in plastic wrap (sometimes I also wrap with foil for good measure) and then freeze for up to several months.
I recommend using my chocolate cake recipe instead for either of those sizes. However, this cake could be baked in those pans, just make sure not to fill the pan more than ⅔ of the way full (you may have to discard a little batter).

Chocolate Bundt Cake
- 2 cups all-purpose flour (250g)
- 1 cup light brown sugar firmly packed (200g)
- 1 ½ cups granulated sugar (300g)
- ⅔ cup natural cocoa powder (68g)
- 1 Tablespoon cornstarch
- ¾ teaspoon baking soda
- ½ teaspoon baking powder
- ¾ teaspoon salt
- ½ cup unsalted butter melted (113g)
- ½ cup canola oil (118ml)
- 2 large eggs + 1 egg yolk lightly beaten (room temperature preferred)
- 1 ¼ cup sour cream (318g)
- 2 teaspoons vanilla extract
- ¾ cup hot coffee or hot water¹ (177ml)
- ½ cup mini chocolate chips (85g)
- Preheat oven to 350F (175C) and thoroughly and generously grease and flour a bundt pan (tap out excess flour) or spray generously with baking spray (not cooking spray, it must contain flour or the cake will stick). Set aside.
- In a large bowl (or in the bowl of a stand mixer) whisk together flour, sugars, cocoa powder, cornstarch, baking soda, baking powder, and salt.
- Add butter and oil and stir well until completely combined (mixture will be thick).
- Add eggs, egg yolk, sour cream, and vanilla extract and stir until smooth and well-combined.
- Gradually add hot coffee or hot water and stir until combined. Stir in mini chocolate chips.
- Pour batter into prepared bundt pan and bake on the center rack for 50-55 minutes or until a wooden skewer inserted in the thickest part of the cake comes out with a few fudgy crumbs or clean. Allow to cool for ten minutes then carefully invert onto a cooling rack to cool completely before covering with chocolate glaze.
- Combine chocolate, butter, and milk in a large microwave-safe bowl. Heat in 30 second increments (stirring well in between) until chocolate and butter are completely melted (mixture may look slightly separated, this is fine).
- Add powdered sugar and whisk until smooth. Allow to cool until mixture is still fluid but no longer runny (about 15 minutes) then drizzle over the top of the chocolate bundt cake. Allow glaze to harden before slicing and serving.
