Chocolate Sour Cream Bundt Cake With Ganache

Save For Later

My Chocolate Bundt Cake is super moist and fudgy thanks to sour cream. It's finished with silky smooth chocolate ganache that perfectly coats every slice. This beauty is in the oven in 10 minutes or less.

We've shared amazing chocolate desserts before like our Death By Chocolate Cake and our decadent chocolate poke cake, but this chocolate Bundt cake is our best yet. The cake has a rich chocolate flavor and always comes out super moist. The best part is it's super easy: no piping bags or pastry school required. We love it for birthdays, potlucks, or anytime you're craving an over the top chocolate dessert.

Why This Recipe Works: A Sprinkle of Food Science

  1. Bakery Soft For Days: Milk adds fat and sour cream's acid tenderizes the gluten. The results a moist soft crumb that doesn't dry out.
  2. Rich Chocolate Flavor: Espresso in the batter and ganache intensify the chocolate flavor. It tastes more chocolately than chocolate on its own could ever be.

Ingredient Notes and Shopping Tips

ingredients including butter, sour cream, white/brown sugars, baking powder, eggs, espresso, and cocoa powder.
  • Butter: Butter should be room temperature: not cold out of the fridge or melted. The sweet spot is that it should give slightly when pressed with your finger. Short on time? Microwave water in a Pyrex measuring cup until boiling then pour it out. Next, place the hot cup upside down over the butter for a few minutes to soften.
  • Sour Cream: Use full fat for the best results. Greek yogurt works too but is slightly tangier in flavor.
  • Cocoa Powder: Sine we're using baking powder, not soda you can use any cocoa powder you like. I suggest Dutch process for the darkest color and richest flavor.
  • Flour: Measure correctly by scooping into your measuring cup and then leveling off with a knife. Dipping the cup into the flour will result in over measuring which can lead to a dry and dense cake.
  • Baking Powder: Replace every 6-12 months. I like to write the date I open it on the lid in Sharpie and toss ~6 months later.
  • Eggs: Bring eggs to room temperature to help everything mix together smoothly. Short on time? Place in a glass of warm not hot water for 5-10 minutes.
  • Chocolate Chips: Use good quality chocolate chips for smooth melting. I like Ghirardelli.

Krystle's Tips: Steal My Culinary School Secrets

  1. Grease Your Pan: I like using Pam baking spray which contains flour. Then I'll dust the pan with cocoa powder. This avoids white flour streaks on our dark cake.  
  2. Don't Overmix: Mix until the flour just disappears. This prevents a tough cake and also lessens the likelihood of tunneling.
  3. Don't Overbake: Test doneness with a toothpick. If it comes out with a few moist crumbs it's done! Don't wait for a clean toothpick which can signal an overbaked cake which will be dry and crumbly.
