Ingredients You’ll Need

1 cup all-purpose flour (125 grams): Provides the structure of the cake. Ensure it’s spooned and leveled for accurate measurements.
¼ cup plus 2 tablespoons unsweetened natural cocoa powder (34 grams): The star of the show, adding that rich chocolate flavor.
¾ teaspoon baking powder & ½ teaspoon baking soda: Both are essential for leavening, giving height and lightness.
½ teaspoon salt: Enhances the flavors of the cake.
½ cup packed light brown sugar (100 grams) & ½ cup granulated sugar (100 grams): Together, they add sweetness and moisture; the brown sugar brings a hint of caramel flavor.
⅓ cup canola oil, vegetable, or avocado oil (80 ml): Keeps the cake moist; avocado oil is a great heart-healthy option.
½ cup buttermilk (120 ml): Adds tang and helps create a tender crumb. You can replace it with plant-based milk mixed with a teaspoon of vinegar or lemon juice.
1 large egg: Binds everything together and provides richness.
1 teaspoon pure vanilla extract: A classic addition that enhances the chocolate flavor. Always opt for pure over imitation for the best taste.
½ cup hot water (120 ml): This helps bloom the cocoa powder, intensifying its flavor.
½ teaspoon instant espresso powder or 1 teaspoon instant coffee (optional): It adds depth to the chocolate flavor. If you don’t use it, the hot water still helps bring a moist texture.

For the frosting:

1 cup unsalted butter, softened (226 grams; 2 sticks): Forms the base of your frosting, ensuring rich and creamy texture.
3 cups powdered sugar (360 grams): Sweetens and gives structure to the frosting.
½ cup unsweetened natural cocoa powder, sifted (45 grams): Deepens the chocolate flavor in the frosting.
3 to 4 tablespoons heavy cream or whole milk (45 to 60 ml): Helps achieve a silky smooth frosting.
1 teaspoon pure vanilla extract & ⅛ teaspoon salt: Complements the frosting and balances sweetness.

How to Make Small Chocolate Cake

Prepare the Oven and Cake Pans: Preheat your oven to 350°F (180°C). Spray two 6-inch round cake pans with nonstick spray and line them with parchment paper circles to prevent sticking.
Mix Dry Ingredients: In a large mixing bowl, sift together 1 cup flour, ¼ cup plus 2 tablespoons cocoa powder, ¾ teaspoon baking powder, ½ teaspoon baking soda, and ½ teaspoon salt. Whisk in the ½ cup granulated sugar and ½ cup packed light brown sugar until thoroughly combined.
Combine Wet Ingredients: Add the ⅓ cup oil, ½ cup buttermilk, 1 large egg, and 1 teaspoon vanilla extract to the dry mixture. Mix until just combined—you want to keep it light and airy.
Incorporate Hot Water: In a separate bowl, mix ½ cup of hot water with the instant espresso or coffee until dissolved. Pour this into the batter and mix everything gently until fully combined. Don’t worry if the batter is thin; it’s supposed to be that way!
Bake the Cakes: Evenly divide the batter between the prepared pans and bake at 350°F for 28 to 33 minutes, or until a toothpick inserted in the center comes out clean. Your kitchen will start smelling heavenly!
Cool the Layers: Once baked, let the cakes cool in the pans for 15 to 20 minutes. Carefully run a knife around the edges, remove from the pans, and transfer to a wire rack to cool completely. For easier handling while frosting, pop them in the freezer for about 30 minutes.
Make the Buttercream Frosting: In a stand mixer or using a handheld mixer, beat 1 cup of softened unsalted butter on medium speed for a minute until smooth. Gradually add the 3 cups powdered sugar and mix. Then, add the ½ cup sifted cocoa powder and mix until completely incorporated.
Finish the Frosting: Add 3 tablespoons of heavy cream, 1 teaspoon vanilla extract, and ⅛ teaspoon salt. Mix on low speed until everything is smooth and creamy. If you find it too thick, feel free to add an extra tablespoon of cream to loosen it up.
Assemble the Cake: Level the tops of each cake layer with a knife or cake leveler. Place the first layer on a plate or cake board. Spread about ¾ cup of frosting on top. Then, flip the second layer upside down and place it on top of the first.
Crumb Coat: Apply a thin layer of frosting around the sides and top of the cake to trap any crumbs. Freeze for about 10 minutes or refrigerate for 20 to set the crumb coat. It makes applying the final layer much easier!
Final Frosting Layers: Use the remaining frosting to beautifully decorate the top and sides of the cake.

Storing & Reheating

To store your small chocolate cake, keep it covered at room temperature for up to 2 days. If you’d like to enjoy it later, refrigerate it for up to 4 days in an airtight container. You can freeze slices individually, wrapped in plastic wrap and foil, for up to three months. When you’re ready to savor it again, let the cake thaw in the fridge overnight; if it’s a bit dry, a light frosting touch-up can rejuvenate the flavor and texture.

Chef’s Helpful Tips

Make sure your butter is at room temperature to ensure it incorporates well into the frosting.
If your cake layers dome up while baking, gently press them down with a clean kitchen towel after they’ve cooled slightly.
Weighing your ingredients gives the best results—some flour can be denser depending on how it’s packed!
Don’t skip the crumb coat; it’s a game-changer for a smooth final look.
Experiment with toppings—fresh berries or chocolate shavings make for lovely additions.

Baking this small chocolate cake is a rewarding experience that beckons creativity and heart. You’ll find the process not only easy but enjoyable, allowing you to bask in the joy of creation. This recipe is an invitation to explore a world of flavor while letting your personality shine through in every sprinkle of frosting or decorative touch.

Recipe FAQs

Can I use different cake pans?

Absolutely! While this recipe is designed for two 6-inch round pans, you can use larger pans. Just keep in mind that baking times may vary, so start checking for doneness a bit earlier.

What if I don’t have buttermilk?

No problem! You can easily create a substitute by adding 1 teaspoon of vinegar or lemon juice to ½ cup of regular milk. Let it sit for about 5 minutes until it thickens slightly.

Can I make this cake ahead of time?

Yes, you can bake the cake layers a day ahead. Just wrap them tightly in plastic wrap before storing them in the fridge to keep them fresh. You can frost it just before serving for the best results.

How should I store leftover cake?

Keep any remaining cake covered at room temperature for up to two days or refrigerate it for up to four days. For longer storage, freeze slices wrapped well to avoid freezer burn. Enjoy!
