This mini chocolate cake is a small cake that serves two made in a round 6 inch cake pan. The recipe makes 4 small slices of cake, which is perfect for two people! The ganache glaze on top is so easy to make and is so pretty garnished with fresh fruit. Small chocolate cake for two people is the best way to celebrate.

6 Inch Chocolate Cake Recipe

The last time I made this mini chocolate cake for two, we ate it in the car on the way to dinner. And if I remember correctly, we had burgers and fries.

It’s not that this cake is ‘light’ or ‘not too sweet’ or whatever it is that people say about dessert to make them feel less badly about eating it. It’s a solid, rich chocolate cake.

The cake has a crumb that is one notch closer to pound cake than boxed cake mix, which I love. The ganache on top is my obsession. I almost never remember to put butter on the counter to soften for cake frosting, and a 2-minute chocolate ganache solves that problem.

If you’re looking for a more standard frosting, try my Chocolate Buttercream recipe.

Why you’ll love this Small Cake Recipe

The best way to celebrate anything is with chocolate, am I right or am I right? I have made this mini chocolate cake for Valentine’s Day, birthdays, anniversaries, job promotions, positive pregnancy test results, and application acceptance celebrations–all of the happy events in my life (and the lives of the people I love). It makes 4 small slices of cake using this 6-inch cake pan, but the cake is still big enough to hold plenty of candles on top! You will love how simple this recipe is, because it’s always easier to make a small cake than a big cake. You’ll be hooked after one bite of the rich, chocolate-y flavor.

Small Cake Recipe Ingredients

White bowls with cocoa powder, sugar, egg, oil and vanilla.
  • Flour. All-purpose, bleached regular flour is what I used to develop this mini chocolate cake recipe. Do not use cake flour, sifted flour, whole wheat or pastry flour for this recipe. If you make changes such as this, the results will not be the same.
  • Cocoa Powder. All-natural, unsweet cocoa powder from the box is what we need, which is not the same as hot cocoa mix.
  • Baking Soda. This cake only calls for baking soda for its rise and lift; it does not require baking powder. The two are not interchangeable, by the way.
  • Oil. The best cake recipes use oil as the base, instead of butter. This is because oil is fully liquid at room temperature, making for a soft, tender cake crumb. This allows you to refrigerate the cake before serving without any hardening, as well. Any type of neutral, flavorless oil works here: canola oil, vegetable oil, sunflower oil, avocado oil, or even safflower oil. Do not use unrefined coconut oil that smells of coconut, because it will alter the whole flavor of your cake.
  • Sugar. Granulated sugar is what we need for this cake, not brown sugar or powdered sugar.
  • Sour Cream. We’re using sour cream for its rich, full flavor, also for the acidity to react with the baking soda and make the cake rise. Sour cream is 40% and it cannot be substituted with anything else. Do not use yogurt, buttermilk, whole milk or even low fat sour cream, if you want perfect results.
  • Egg. While a lot of my small batch recipes call for part of an egg, we need the whole egg for this mini chocolate cake recipe.
  • Vanilla Extract. The best flavor is found in real, pure vanilla extract. My preference is for one made with Bourbon.
  • Coffee. This cake will not taste like coffee, though if you’re looking for that, try my Mocha Cupcakes. The coffee here provides moisture and a flavor boost for the chocolate.
  • Chocolate. We need chopped semisweet chocolate to melt for the chocolate ganache for this mini chocolate cake. I reach for a baking bar or my favorite bar of chocolate to chop up.
  • Heavy Cream. We will melt the chocolate into a small amount of heavy cream.
  • Optional: A small amount of light (clear) corn syrup makes the ganache super shiny, but it is entirely optional. I like to use fresh fruit for decorating.

How to Make a Mini Chocolate Cake

I’m going to help you out with all of your Valentine’s Day dessert for two needs, but first: you’re going to need a 6″ cake pan to make this mini chocolate cake. They’re adorable. And once you buy one, you can make all of my small cake recipes. (Plus, I even use it to make a small batch of fudge, too!).

Preheat the oven to 350-degrees Fahrenheit, and have your pan ready. Line the bottom with a circle of parchment paper, and lightly spray the sides with a non-flavored cooking spray.

Brown bowl with flour and cocoa powder in it.
Egg, sugar, vanilla and sour cream in white bowl.

Whisk the dry ingredients together: the flour, cocoa powder and baking soda; set aside.

In a separate small bowl, whisk together the oil, sugar, sour cream, egg, vanilla and coffee. It’s not necessary to use an electric mixer, whisking by hand is totally fine.

Pour the wet ingredients into the dry ingredients and stir together until no streaks of flour remain.

Pour the mini chocolate cake batter into the prepared pan, slide into the oven and bake for 29-32 minutes. Use a toothpick to ensure the cake is done before removing it from the oven.

While the cake cools, make the chocolate ganache frosting: in a double boiler, or bowl fitted over a pan of simmering water, combine the chopped chocolate, cream, and corn syrup (if using). Stir over medium heat until melted and smooth. Alternatively, you can melt the chocolate and cream in the microwave in 25-second pulses on LOW power. Stir between each pulse.

Pour the chocolate ganache over the cake on a cake stand, garnish with fresh fruit, and serve.

Prep Time 20 minutes
Cook Time 32 minutes
Total Time 52 minutes

Ingredients

For the cake:

  • 1/2 cup all-purpose flour
  • 5 tablespoons unsweetened cocoa powder
  • 1/2 teaspoon baking soda
  • 1/3 cup neutral oil (like canola or grapeseed)
  • 1/2 cup granulated sugar
  • 1/3 cup full-fat sour cream
  • 1 large egg
  • 1/2 teaspoon vanilla extract
  • 1 tablespoon warm coffee

For the ganache:

  • 3 ounces semisweet chocolate, chopped
  • 1/4 cup heavy cream
  • splash of light corn syrup (to keep the frosting smooth, optional)
  • pomegranate arils, for garnish

Instructions

  1. Preheat the oven to 350, and position a rack in the lower third of the oven.
  2. Line a 6" round cake pan (with 2" sides) with parchment paper on the bottom, and lightly grease the sides with oil.
  3. Next, in a medium bowl, whisk together the flour, cocoa powder, and baking soda. Set aside.
  4. In a small bowl, whisk together the oil, sugar, sour cream, egg, vanilla and coffee.
  5. Combine the two bowls, mixing just until combined.
  6. Pour the batter into the cake pan, and bake for 29-32 minutes, or until a toothpick inserted into the cake comes out clean. If you under-bake the cake, it will slightly sink, so check it! It will also start to pull away from the sides when it's done.
  7. Remove the cake from the pan by carefully tilting it into one hand, peel off the parchment from the bottom, and then place it on a small cake stand.
  8. In a double boiler, or bowl fitted over a pan of simmering water, combine the chopped chocolate, cream, and corn syrup (if using). Stir over medium heat until melted and smooth. *Alternatively, you can melt the chocolate and cream in the microwave in 25-second pulses on LOW power. Stir between each pulse.
  9. Pour the chocolate over the cake, and garnish with pomegranate arils.

    I doubled the recipe to make a birthday layer cake to serve 3. I used a half batch of the chocolate buttercream frosting to use between the layers, then had enough to frost the sides of the cake. Then I used the ganache over the top. The pomegranate seeds were a nice contrast to all of the sweet. Delicious!

    This is so good. Just the right size for my husband and I. I didn;t frost it , just used cabot whipped cream. yummy.

  4. L says:

    This is the best chocolate cake recipe ever. Bakes perfectly every time which is amazing compared to the time putting the ingredients together. I’ve used it for so many cakes; strawberry and cream, plain with a dusting of chocolate powder, but the best is my cheat; I mix melted butter (1 tbsp) with Nutella and viola I have a Nutella ganache.
    I think your web site is the best, fabulous recipes and entertaining to boot.

    Hi Christina,
    Can you please let me know how to double this recipe? I want to make it with 1 cup flour for my son’s birthday. He really likes your cake.

    1. Christina Lane says:

      I would make it twice in two 6-inch pans, stack them together and frost them like a mini layer cake :)

  6. Sadie says:

    I made 6 cupcakes and they were excellent! The crumb is moist, tender, and light, but not fragile. Instead of coffee, I added a few teaspoons of instant espresso to enhance the chocolate flavour. I also added a pinch of cinnamon. The only other change I made was to sub yogurt for the sour cream. The cupcakes were even better the next day.

  7. Mimi says:

    My 3-year old granddaughter and I made mini cupcakes using this recipe. They were excellent! We had so much fun making them. The recipe made 24 cupcakes. Working with a 3-year old, I appreciate how easy it was to make them. She was so proud to take some home for her family. We’ll definitely make them again.

  8. Francesca says:

    This turned out perfect! So elegant and tasty too. Thank you!

  9. Veronica says:

    Can I use semisweet chocolate chips instead of a chocolate bar or is the chip version different than the bar version?

  10. Monica says:

    Yum! I made a raspberry syrup to add to the ganache, and made a raspberry buttercream for the middle. It was rich enough with the added buttercream that it could have easily fed 6-8 people. Great recipe for smaller gatherings when I don’t want to make a full size!
