Sourdough Chocolate Mocha Cake

Hey Kids, its time for Sourdough Sunday! Yay!

Joel keeps laughing at me that I’ve had this sourdough starter for over a month now, and I have yet to actually bake any bread with it. Haha, I just can’t help myself, there are so many other cool things to do with it! Like this, for instance:

That’s right – CHOCOLATE CAKE!

When I took this cake out of the oven, I was a little
worried. It didn’t rise very much at all. In fact, it was fairly wimpy looking.
So I went back online to try and figure out what I did wrong. All the recipes I
found online were completely different from what I did.  I almost, almost just chucked this thing
right in the trash.
I double checked the recipe I wrote down, and yup, wouldn’t
you know it…I totally forgot to put the baking powder and the baking soda in!
Dang it!! But I know when you make this, you won’t forget, and your cake will
rise beautifully for you! And even in its little stunted self, this cake was very moist and delicious. The tanginess of the sourdough, the coffee, the hint of chocolate, this cake was awesome. I hope you make it soon! 
Ok, one last note. I have completely lost where this recipe came from. I had it open on my phone, and then it wasn’t there. I think Ladybug must have closed it. She has become obsessed with the coolest iPhone app of all time, Peekaboo Farm, and sometimes she accidentally closes out of it and then goes exploring other places. Like sending strange texts to friends (LOL Abby!). So, in short, I did not come up with this recipe, but I cannot for the life of me find where it came from. But good job to whoever did!
Chocolate Mocha Sourdough Cake
1 stick butter, room temperature
1 ¼ cup sugar
3 eggs
3 Tbsp baker’s cocoa
3 Tbsp vegetable oil
1 Tbsp instant coffee
1 tsp baking powder
1 tsp baking soda
½ tsp salt
1 tsp vanilla extract
2 cups active sourdough starter
Preheat the oven to 375 degrees.
Measure the sugar and butter together into a large bowl.
Using a fork, mix them together until they are thoroughly
Add the eggs and the vanilla, one at a time.
Add in the cocoa, vegetable oil, baking powder, baking soda,
and sourdough starter.
Mix thoroughly.
If the mixture seems too thick for cake batter, add ¼ cup of
milk, slowly, until it becomes the correct consistency. DO NOT add too much
milk, or all will be lost!
Pour into a greased bundt pan.
Bake for at least 35 minutes, or until a toothpick inserted
comes out clean.
Cool in the pan for 10 minutes, and then turn out onto a
cooking rack.
You can add a bit of powdered sugar to the top of this,
serve it plain, or whip up a little bit of coffee-powdered sugar glaze like I

    Hi Jenni! Wow this cake looks great. I love that if uses sourdough starter! I'd love to try this, but I don't know how to make a starter. (I tried once during the summer, but it didn't turn out so well, as in the starter just kind of sat there and didn't poof up or anything). Any advice?

    Hi Kyleen! I didn't actually make my own starter, I was handed down part of someone else's. But I will try to help anyway! There are, quite literally, a billion ways to make your own starter, but it is really quite simple. Check out this article from Peter Reinhart ( And here is another good recipe (although this one you have to read the article ot find the recipe, its hidden in there!)

    I hope this helps!!

    I just made this cake. The batter is yummy. I am concerned that it did not list flour. Hopefully the sourdough starter has enough flour. If not, I will let you know.

      I know it seems scary, but trust your starter!

    The cake turned out very tasty. I guess flour is not needed. Now we will see how my guests enjoy.

    You said you didn’t know where this recipe came from? There was a Betty Crocker Magazine called “Sphere” in the 70s. My sister was wild about a cake by the name of-Chicolate Mocha Sourdough cake-this looks just like it. She lost the magazine years ago-we’re going to try it!
