Chocolate Sour Cream Doughnut Bundt Cake

Are you ready for cake?  Because I’ve got cake!  This classic Chocolate Sour Cream Doughnut Bundt Cake is a nod to that irresistibly glossy chocolate doughnut that calls to you from the doughnut shop case…

I aim to please here at tvfgi, and when a reader asks for a chocolate version to be next up in my popular series of doughnut bundt cakes, I oblige!  I have to say it was a pretty good idea, you readers are so smart 🙂  I’m always open to suggestions…so let me know which doughnuts you crave in bundt cake form ~ drop them in the comments, I’m ready for #4!

My doughnut bundt cake series is growing ~ here are the first two in the lineup, they’ve already gotten rave reviews :

• Apple Cider Doughnut Cake

• Glazed Old Fashioned Buttermilk Doughnut Bundt Cake

I think you can literally see how good this cake is…it’s chocolatey but not too rich, with a nice even ‘dough-nutty’ crumb.  The sour cream and buttermilk make a nice tender cake.  I use part oat flour just as I did in my previous doughnut bundt cakes, and I highly recommend you give it a try.

Why do I use oat flour in my bundt cake?

I’ve discovered that a combination of regular all purpose flour and oat flour results in a perfect cake crumb, along with an extra nutrition boost from the whole grain oats, and a lovely flavor.  You can buy oat flour in most supermarkets, and you can always find it online.

If you’re interested, it’s super easy to make it yourself.  See my post about How to Make Oat Flour for all the details!

Bundts are great because you get the ‘wow’ factor of a fabulous cake without all the fuss of a traditional layer cake.  This recipe is so easy, you’ll just whisk the dry, whisk the wet, and whisk the two together.  Bake, cool, then slather it with ganache (that’s the fun part.)

My chocolate sour cream doughnut bundt cake looks and sounds extravagant, but honestly, it’s not overwhelmingly sweet or rich.  I don’t recommend it as an after dinner type of dessert, it’s truly a brunch or coffee break treat, not over the top at all.   It’s the perfect ‘what can I bring‘ recipe for a brunch, office party, book club, etc.  The glossy glaze and chocolate sprinkles guarantee it a good reception.

• Cooking notes:
  Sour cream and buttermilk make a tender, moist cake.  You can substitute milk, but the end result will not be as moist.  It’s the little things that make a cake special, like oat flour, sour cream, buttermilk, and, of course, chocolate ganache!  That little bit of espresso powder?  It encourages the chocolate flavor to bloom.  Find it with the regular coffees in your supermarket.

Course brunch, Dessert

Cuisine American

Prep Time 15 minutes

Cook Time 50 minutes

Total Time 1 hour

Yield 20 servings

Equipment

• standard 10 cup bundt pan

Ingredients

dry ingredients

• 1 and 2/3 cups all purpose flour
• 1/3 cup cocoa powder
• 1 and 1/2 cups oat flour
• 1 and 1/2 cups sugar
• 1 and 1/2 tsp baking powder
• 1/2 tsp baking soda
• 1/2 tsp salt

wet ingredients

• 1 cup sour cream
• 3/4 cup buttermilk
• 3/4 cup vegetable oil I use safflower or canola
• 3 large eggs room temperature
• 1 tsp instant espresso powder or instant coffee powder, not liquid
• 2 tsp vanilla extract

glaze

• 1 cup dark chocolate chips
• 1 Tbsp corn syrup
• 2/3 cup heavy cream

garnish

• chocolate sprinkles

Instructions

• Preheat oven to 350F
• Prepare a bundt pan by carefully buttering the entire surface, and then dusting with flour. Shake off excess flour.
• Whisk the dry ingredients together in a large mixing bowl.
• Whisk the wet ingredients together in a another bowl.
• Add the wet ingredients to the dry and whisk until just combined, don't over mix.
• Pour the batter into the prepared pan and bake for 45-50 minutes, until a toothpick inserted near the center comes out without wet batter clinging to it. I always check my cakes on the early end, at 45 minutes. Give it a few extra minutes if it doesn't quite look done.
• Set the pan on a cooling rack for 15 minutes. Then invert the cake and then let cool completely before glazing. It helps to loosen the edges with a small spreading knife first. Go along the outside edges and also the inside tube edge, gently prying the cake away from the pan to loosen it.
• To make the glaze, put the chocolate and the corn syrup in a bowl. Heat the cream until it comes to a simmer, I do this by putting it into the microwave for one minute, you can do it in a small saucepan if you like. Pour the hot cream over the chocolate and let sit for 5 minutes. Then stir until the mixture is creamy and glossy, with no lumps. If there is any remaining unmelted chocolate you can microwave it for a short 15 second burst to reheat the mixture. Let the ganache sit for a few minutes to thicken if it seems too thin.
• Pour the glaze evenly over the entire cake, and immediately shower with sprinkles.

Make this Chocolate Sour Cream Doughnut Bundt Cake your own ~

• You might have noticed I left the nutmeg out of this cake, even though it was in both previous doughnut cakes…I think the flavor will get overpowered by the chocolate, but feel free to add it if you like.
• Use mini chocolate chips instead of sprinkles.  You can even fold regular chocolate chips into the batter for a more ‘chocolatey’ cake.
