Small Chocolate Cake (6 Inch)

Small cakes are certainly convenient for small celebrations. This 1 layer 6 inch chocolate cake serves 4, so it’s perfect for date night, a Valentine’s Day dessert, a small family birthday celebration, or for whenever you need a scaled down cake. We love it with chocolate ganache on top. You can also use this chocolate cake batter to make a small batch of cupcakes.

This is a 1 Layer 6 Inch Chocolate Cake

Over the past year, we’ve received many requests for smaller variations of normally large desserts. We’ve directed a lot of bakers to our 6 inch cakes blog post, where I teach you how to turn cupcake batter into a 6 inch layer cake. But what if you don’t need 3 layers?

Here’s our 1 layer 6 inch chocolate cake recipe. I worked on this recipe with Valentine’s Day on my mind. Wouldn’t it be nice to make a tiny cake without a ton of leftover slices? But even beyond that holiday, it’s massively convenient to have a dessert option for small gatherings, families, celebrations, or just a casual at-home date night.


Small Chocolate Cake Details

  • Flavor: This cake is sweet with divine chocolate flavor, especially when you pair it with deep dark chocolate ganache (recipe included below). Wait for the cake to cool completely before digging in. I find its chocolate flavor develops after a few hours.
  • Texture: If it’s not over-baked, this cake is soft, rich, and indulgently moist. Have you ever made the sour cream version of my larger chocolate layer cake? The texture is pretty much identical. Any unfrosted edges become delicately crisp (not in a bad way!), which adds a little textural dimension to each slice.
  • Ease: Since the cake is so small and there’s no elaborate decorating required, this is a very manageable recipe for beginner bakers. The ingredient list is pretty straightforward and you don’t even need to use a mixer.
  • Time: Set aside a few hours to complete this cake recipe. The cake is pretty thick, so it takes close to 30 minutes to bake through. The longest stretch of time, however, is waiting for the cake to cool.
  • Equipment: Nothing special except for a 6 inch cake pan (affiliate link to the exact cake pans I use and love).

Overview of the Ingredients & Process

Though you can find the full printable recipe below, let me walk you through a couple steps and answer some possible questions that may arise.

The batter comes together in 2 mixing bowls. Whisk flour, unsweetened natural cocoa powder, baking soda, espresso powder, and salt together in one bowl. The espresso powder is optional, but definitely use it if you have it. Espresso powder accentuates and deepens the chocolate flavor. In another bowl, whisk oil, sugar, egg, vanilla extract, and buttermilk. Buttermilk is our acidic ingredient and crucial for this cake’s rise. If you don’t have buttermilk, use the DIY version detailed in the notes below.

Expect a semi-thick cake batter. 

bowls of ingredients and a 6 inch cake pan

Like I recommend with all my 6 inch cakes, use a parchment paper round. Trace the bottom of your 6 inch cake pan on a large piece of parchment paper. Cut out the parchment circle. Very lightly grease the cake pan. Place the parchment round inside. Grease the parchment round too. Using butter or nonstick spray, I grease the pan AND the parchment. This promises an ultra non-stick environment for your small chocolate cake.

Though its diameter is small, this is a thick chocolate cake. It’s pretty moist, too. Because of its thickness and delicious moisture, the cake may sink a little in the very center. Don’t fret over that. (Cover it up with ganache!) As long as a toothpick inserted in the center of the cake comes out clean, it’s done.

Toppings

You can top this small chocolate cake with chocolate ganache (recipe included below), buttercream, or whipped cream. For a thick layer of buttercream, I recommend halving this chocolate buttercream, this strawberry buttercream, this peanut butter frosting, or this vanilla buttercream. For a lightly sweetened whipped cream topping, you could halve the mocha whipped cream paired with my flourless chocolate cake or halve this vanilla whipped cream recipe.

The pictured heart sprinkles are from this sprinkle set. (Affiliate link.) And I bought this adorable pink cake stand from Home Goods 2 years ago.

Use This Batter for 6 Chocolate Cupcakes

So what if you want a smaller batch of chocolate cupcakes? Yes, you can absolutely use this recipe. This chocolate cake batter yields about 1 and 1/2 cups of batter total, which makes 6 standard size cupcakes. How does it weigh up against my standard chocolate cupcakes recipe? Well, this batter is a little thicker so the cupcakes aren’t quite as light, delicate, and spongy. They’re soft and moist, but have a slightly heavier crumb.

  • For a cupcake topping, use any of the topping options listed above.
  • For the pictured frosted cupcakes, I used the chocolate ganache recipe below. After the ganache cools completely, you can beat it with an electric mixer for about 3-4 minutes to make whipped ganache. Tastes like chocolate mousse! You can read more about it in the recipe below or in my chocolate ganache post.

What About a Vanilla Version?

I don’t have a vanilla version of this recipe at this time. Though I haven’t tested it, I’m confident you could halve this homemade sprinkle cake recipe to yield a 1 layer 6 inch vanilla cake or 6 vanilla cupcakes. Feel free to skip the sprinkles.

Description

This 1 layer 6 inch chocolate cake serves 4, so it’s perfect for any occasion requiring a scaled down cake. You can also use this chocolate cake batter to make a small batch of chocolate cupcakes. For best success, review the recipe notes before starting.


Ingredients

  • 1/2 cup (63g) all-purpose flour (spoon & leveled)
  • 1/4 cup (21g) unsweetened natural cocoa powder
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon espresso powder (optional)
  • 1/4 teaspoon salt
  • 1/4 cup (60ml) vegetable oil
  • 1/2 cup (100g) granulated sugar
  • 1 large egg, at room temperature
  • 1/2 teaspoon pure vanilla extract
  • 1/4 cup (60ml) buttermilk, at room temperature

Chocolate Ganache

  • one 4-ounce quality semi-sweet chocolate bar (113g), finely chopped
  • 1/2 cup (120ml) heavy cream or heavy whipping cream
  • optional garnish: raspberries, mint, and/or sprinkles

Instructions

  1. Preheat oven to 350°F (177°C). Grease a 6×2 inch cake pan, line with parchment paper, then grease the parchment paper. Parchment paper helps the small cake seamlessly release from the pan. I usually grease it with nonstick spray.
  2. Make the cake: Whisk the flour, cocoa powder, baking soda, espresso powder, and salt together in a large bowl. In a medium bowl, whisk the oil, sugar, egg, vanilla extract, and buttermilk together in a medium bowl. Pour the wet ingredients into the flour mixture and whisk until smooth and combined.
  3. Pour the cake batter evenly into prepared cake pan.
  4. Bake for around 27-30 minutes or until the cake is baked through. To test for doneness, insert a toothpick into the center of the cake. If it comes out clean, it’s done. Avoid over-baking. Cake is thick and moist, so the center may slightly sink. That’s normal. Allow cake to cool in the pan set on a wire rack. Cool completely before frosting.
  5. Make the chocolate ganache as the cake cools because the ganache must cool too: Place chopped chocolate in a medium heat-proof bowl. Heat the cream in a small saucepan over medium heat until it begins to gently simmer. (Do not let it come to a rapid boil– that’s too hot!) Pour over chocolate, then let it sit for 2-3 minutes to gently soften the chocolate. With a metal spoon or small rubber spatula, very slowly stir until completely combined and chocolate has melted. Ganache will be thin, so let it cool and thicken for at least 30-60 minutes before using. Refrigerating speeds this up, but the ganache will not cool evenly. Stir it a few times as it sets in the refrigerator so it remains smooth. You can also let the ganache fully cool and thicken (takes about 2 hours). After 2 hours, you can whip the cooled ganache with a handheld or stand mixer fitted with a whisk attachment until light in color and texture, about 3-4 minutes on medium-high speed. (Whipped ganache can be spread or piped. It is pictured on the cupcakes in the post above. I used Wilton 1M piping tip.)
  6. Spread ganache on cooled cake. If ganache has cooled and thickened enough (or if you whipped it), you could pipe it with a piping bag/tip. Decorate with optional garnishes, if desired. Slice and serve.
  7. Cover leftover cake tightly and store at room temperature for 1 day or in the refrigerator for up to 5 days.

Notes

  1. Make Ahead & Freezing Instructions: The cake can be baked, cooled, and covered tightly at room temperature overnight. Frosted or unfrosted cake can be frozen up to 2-3 months. If desired, see my How to Freeze Cakes post. Thaw cake overnight in the refrigerator and bring to room temperature before decorating/serving. For make-ahead instructions for the chocolate ganache, see step 5 in my chocolate ganache post.
  2. Cocoa Powder: Use natural cocoa powder, not dutch-process. (See dutch-process vs natural cocoa powder for more information.)
  3. Espresso Powder: Espresso powder will not make the cake taste like coffee. Instead, it deepens the chocolate flavor. It’s optional, but for best taste, I highly recommend it. You can use the same amount of instant coffee (the powder) instead of espresso powder if desired.
  4. Amount of Sugar: I tested this recipe with 6 Tablespoons of sugar and the cake wasn’t as sweet, of course, but it tasted pretty plain. I recommend sticking with 8 Tbsp (1/2 cup). Topping with chocolate ganache definitely balances out the sweetness.
  5. Buttermilk: Buttermilk is required for this recipe. You can make your own DIY version of buttermilk if needed. Add 1/2 teaspoon of white vinegar or lemon juice to a liquid measuring cup. Then add enough whole milk to the same measuring cup until it reaches 1/4 cup. (In a pinch, lower fat or nondairy milks work for this soured milk, but the cake won’t taste as moist or rich.) Stir it around and let sit for 5 minutes. The homemade “buttermilk” will be somewhat curdled and ready to use in the recipe.
  6. 6 Cupcakes: Preheat oven to  350°F (177°C). Line a standard 12-count muffin pan with 6 liners. Prepare the batter as directed in step 2 above. Pour or spoon the batter into the liners. Fill each 2/3 full to avoid spilling over the sides or sinking. Bake for 20-22 minutes, or until a toothpick inserted in the center comes out clean. Don’t over-bake, which will dry out the cupcakes. Allow the cupcakes to cool completely before frosting.
  7. Chocolate in Ganache: Ganache will only set if the correct chocolate is used. You can use high quality chocolate chips if needed (I prefer Ghirardelli semi-sweet chocolate chips), but I recommend using pure chocolate baking bars. You can find them right next to the chocolate chips in the baking aisle. They are sold in 4 ounce bars. I like Bakers or Ghirardelli brands. You can use other varieties of chocolate too, such as milk chocolate (aka German Chocolate) or Dark Chocolate. If using white chocolate, reduce the cream to 1/3 cup (80ml). White chocolate is softer, so you need less cream.
  8. Dairy-Free Alternative for Heavy Cream in Ganache: Use 1/2 cup full-fat canned coconut milk. Shake it up before opening and measuring. Whisk on the stove as it heats and bring to a simmer.
  9. 8 Inch Pan or 2 Layer Cake: You can use this cake batter in an 8×2 inch cake pan. The cake will be thinner and the bake time is about 24-25 minutes, but use a toothpick to test for doneness just as instructed above. I don’t recommend doubling this recipe to make a 2 layer cake because it will be quite thick and taste heavy. Instead, divide the batter between two 6-inch cake pans (bake time would be shorter) or divide this chocolate cupcake batter in 2 6-inch cake pans. Start checking with a toothpick at 26 minutes.

  1. Would you recommend this recipe if I want to add crushed oreo’s to the batter? I need a small batch of cupcakes. Thanks

    1. Lexi @ Sally's Baking Addiction says:

      Hi Gina, we haven’t tried it ourselves but we can’t see why that wouldn’t work. This is a very small amount of batter so you shouldn’t need much — start off with just 1/4 cup or so of crushed Oreos. Let us know how it goes!

  2. Hi Sally, all your recipes are wonderful. I have just started watching and reading them. Can u tell me your cup measurement
    Is it 1 cup = 250 ml??

    1. Trina @ Sally's Baking Addiction says:

      Hi Mani! This blog post includes a helpful measurement chart of common weights – we measure 1 cup as 240ml.

  3. Thank you so much. I use 1 cup =250 ml. Would that make a difference in baking cakes cookies while following your recipes? Do reply

    1. Trina @ Sally's Baking Addiction says:

      Hi Mani! We recommend sticking with the measurements listed in our recipes for best results.

  4. Could I double the recipe to make 12 cup cakes?

    1. Lexi @ Sally's Baking Addiction says:

      Hi Sundie, for 12 cupcakes, we’d recommend using our Super Moist Chocolate Cupcakes recipe instead.

  5. I want to make a 7inch 2 layer cake, what do you suggest

    1. Trina @ Sally's Baking Addiction says:

      Hi G, here is everything you need to know about converting recipes to different Cake Pan Sizes. It may be helpful to start from our 9 inch two layer triple chocolate cake recipe instead.

  6. can you use whole wheat flour instead of all purpose flour?

    1. Lexi @ Sally's Baking Addiction says:

      Hi A, we don’t recommend it here. Best to stick with all-purpose!

  7. Christi Klemm-Hebeler says:

    Thank you for this recipe for “the perfect chocolate cake”! It’s heavenly! Love chocolate ganache. Would take that over buttercream frosting any day! But to each their own! This will be a repeat in our house!

  8. LINDA ORFIELD says:

    I baked your Small Chocolate Cake this morning to take to a friend who recently had surgery. I won’t get to taste it, but I KNOW it will be delicious! I was impressed how quick and easy it was to make. With the whipped chocolate ganache and a pretty cake plate, the cake makes a beautiful presentation. Thank you for all your amazing recipes. So many of them have become my “go to” dessert recipes. I have always been a pie person, but your recipes have made me a cake person, too!

    1. Trina @ Sally's Baking Addiction says:

      Thank you so much for this sweet review, Linda!

  9. Nora Muhammad says:

    Hi Sally! I tried your recipe for our Eidul Fitr celebration. I’m diabetic, so I replaced the sugar with stevia blend and made my own buttermilk. I doubled the recipe to make a 2-layer cake and I used another recipe for chocolate ganache that uses milk or non-dairy milk. It’s a huge success! The texture of the cake is just right! Thanks for the recipe!

  10. Hi Sally!
    I would like to make this cake in an 8×8 square pan. Would I need to double the recipe for that?
    Thanks!

    1. Trina @ Sally's Baking Addiction says:

      Hi Nancy, We’re unsure exactly how much batter you would need for an 8×8 pan, but this Cake Pan Sizes and Conversions Guide should be helpful!

      1. According to the conversion guide, it looks like an 8 inch square pan is twice the volume of the 6 inch round pan. So I should double the recipe.
        Thanks!
