If you’re craving chocolate, this mini chocolate cake with chocolate buttercream is for you! It’s got all the chocolatey goodness you want, but in a smaller size, perfect for two, or for one die-hard chocolate lover.

You might recognize some of this recipe from my mini vanilla cake recipe — this is the chocolate version for all you chocolate fans! I personally prefer vanilla, but sometimes you just NEED chocolate! And this cake is for those times. You’ll follow the same general process as the mini vanilla cake, with just a couple extra ingredients.

Small-Batch Cake

This cake is the perfect size. Especially now while we’re all avoiding large gatherings, unless you want tons of leftovers you need a small batch cake recipe! Depending on how large you cut the slices, it yields 4-6 servings, which is plenty for a group of up to three! You can enjoy cake while watching portion sizes, limiting sugar intake, and avoiding too many leftovers!

6-inch Cake Pan

To make this cute little cake, you’ll need a 6-inch round cake pan. I use this Wilton one (affiliate link). You can also try making it in a small loaf pan, a small cast-iron skillet, or as a few cupcakes. If you try that, let me know in the comments below how it works for you!

This mini chocolate cake recipe is so easy. You just need a few pantry staples and one key ingredient!

  • an egg
  • pure vanilla extract
  • sugar
  • vegetable oil
  • buttermilk
  • all-purpose flour
  • unsweetened cocoa powder
  • baking powder
  • baking soda
  • espresso powder
  • salt
  • hot water

For the chocolate buttercream frosting, you just need to gather

  • salted butter
  • powdered sugar
  • cocoa powder
  • heavy cream
  • pure vanilla extract

And then you’re ready to put together this lovely little chocolate cake!


This is a ONE-BOWL RECIPE!! To make the cake batter, you only need a bowl and a whisk (and I guess some way to heat up your water). It’s so simple and quick, and makes such a delicious mini chocolate cake. Here’s how to make it:

  1. Combine your eggs, vanilla extract, and sugar in a bowl. Whisk them together so they’re smooth.
  2. Whisk in your oil and buttermilk.
  3. Sift in your dry ingredients: flour, cocoa powder, baking powder, baking soda, espresso powder, and salt. Gently whisk until just barely combined.
  4. Stir in the hot water — I just warm mine up for about 45 seconds in the microwave. This helps to bring out the flavor and fudginess of the cocoa powder.
  5. Then you’re ready to bake!

The chocolate buttercream frosting is even easier!

  • Just beat your butter with a hand mixer to get it fluffy.
  • Mix in your powdered sugar and vanilla.
  • Mix in your heavy cream until the frosting is thick and fluffy.

That’s it! This is the perfect antidote to your chocolate craving, and it couldn’t be easier.
