Essential tools to make this recipe perfectly
This recipe is designed for simplicity and maximum chocolate flavor. Here’s why it’s a winner:
- Scaled-Down Ingredients: The ingredient quantities are carefully calibrated to produce a small cake with the perfect texture and flavor. No complicated math or half-used ingredients left over.
- Simple Mixing Method: This recipe uses a straightforward mixing method that’s easy for even beginner bakers. No need for fancy equipment or techniques.
- Moist and Tender Crumb: The combination of oil, buttermilk (or a buttermilk substitute), and hot water creates a cake with a wonderfully moist and tender crumb.
- Intense Chocolate Flavor: Using both cocoa powder and melted chocolate ensures a deep, rich chocolate flavor that will satisfy any chocolate craving.
- Fast Baking Time: Because the cake is small, it bakes quickly, meaning you can have a warm, delicious chocolate cake in your hands in no time.
Ingredients
- Flour: 1/2 cup (60g) all-purpose flour.
- Cocoa Powder: 1/4 cup (20g) unsweetened cocoa powder. Dutch-processed cocoa powder will give a richer, darker flavor.
- Sugar: 1/4 cup (50g) granulated sugar.
- Baking Soda: 1/4 teaspoon.
- Baking Powder: 1/8 teaspoon.
- Salt: 1/8 teaspoon.
- Oil: 2 tablespoons (30ml) vegetable oil or canola oil.
- Buttermilk: 1/4 cup (60ml) buttermilk. If you don’t have buttermilk, you can use regular milk with 1/2 teaspoon of lemon juice or vinegar added and let it sit for 5 minutes.
- Vanilla Extract: 1/2 teaspoon.
- Hot Water: 1/4 cup (60ml) hot water.
- Melted Chocolate: 1 ounce (28g) semi-sweet or dark chocolate, melted and slightly cooled.

Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Grease and flour a 6-inch round cake pan or a similar sized oven-safe dish. You can also use a few ramekins if you prefer individual servings.
- Combine Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, sugar, baking soda, baking powder, and salt. Make sure there are no lumps of cocoa powder.
- Add Wet Ingredients: Add the oil, buttermilk, and vanilla extract to the dry ingredients. Mix until just combined. Be careful not to overmix.
- Stir in Hot Water and Melted Chocolate: Gradually pour in the hot water while mixing. The batter will be thin. Then, stir in the melted chocolate until evenly distributed.
- Pour into Pan: Pour the batter into the prepared cake pan or ramekins.
- Bake: Bake for 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs attached. Baking time may vary depending on your oven and the size of your pan.
- Cool: Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
- Frost (Optional): Frost with your favorite frosting, such as chocolate buttercream, ganache, or a simple dusting of powdered sugar.
- Enjoy! Slice and enjoy your delicious small chocolate cake.
Tips for Success
- Don’t Overmix: Overmixing can lead to a tough cake. Mix the batter until just combined.
- Use Good Quality Cocoa Powder: The quality of your cocoa powder will significantly impact the flavor of the cake. Use a good quality unsweetened cocoa powder for the best results. Dutch-processed cocoa powder will give a richer, darker flavor.
- Measure Accurately: Baking is a science, so accurate measurements are important. Use measuring cups and spoons, and level off dry ingredients.
- Don’t Overbake: Overbaking will result in a dry cake. Check the cake for doneness after 20 minutes and adjust the baking time as needed.
- Cool Completely Before Frosting: Frosting a warm cake will cause the frosting to melt. Make sure the cake is completely cool before frosting.
- Buttermilk Substitute: If you don’t have buttermilk, you can use regular milk with 1/2 teaspoon of lemon juice or vinegar added and let it sit for 5 minutes. This will create a similar tangy flavor and texture.
- Add-Ins: Feel free to add chocolate chips, nuts, or other mix-ins to the batter for extra flavor and texture.
Storage Instructions
Store leftover cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. If storing in the refrigerator, allow the cake to come to room temperature before serving for the best flavor and texture. You can also freeze the cake for up to 2 months. Wrap the cake tightly in plastic wrap and then in foil before freezing.
