Ingredients You’ll Need

2 cups all-purpose flour: Helps give the cake structure. If gluten-free is preferred, try a 1:1 gluten-free flour blend.
2 cups granulated sugar: Adds sweetness and moisture. Brown sugar can be substituted for a different flavor profile.
½ cup unsweetened cocoa powder: Essential for that deep chocolate flavor. Dutch-process cocoa can enhance richness.
2 teaspoons baking soda: Acts as a leavening agent to make the cake rise.
1 teaspoon baking powder: Provides additional lift for a fluffy texture.
½ teaspoon salt: Enhances the sweetness and balances flavors.
2 large eggs: Essential for binding ingredients; room temperature eggs work best for even mixing.
1 cup vegetable oil: Keeps the cake moist; can be substituted with melted coconut oil for a nuanced flavor.
1 cup whole buttermilk, shaken: Contributes to the cake’s moisture and tanginess. You can make a buttermilk substitute using regular milk and vinegar.
1 cup hot coffee (or hot water): Enhances the chocolate flavor. If you prefer not to use coffee, hot water works just fine.
½ cup (1 stick) salted butter: Used for the luscious frosting; you can use unsalted and adjust the salt in the recipe.
⅔ cup unsweetened cocoa powder: For the frosting to keep that chocolatey goodness going.
3 cups confectioners’ sugar, sifted: Gives the frosting its smooth texture; sifting prevents lumps.
⅓ cup whole buttermilk, shaken: Adds hydration to the frosting.
1 teaspoon vanilla extract: It elevates the flavor of the frosting, making it more aromatic.

How to Make One Bowl Buttermilk Chocolate Cake

Prepare the Baking Pan: Preheat your oven to 350°F (175°C). Grease and flour a 9 x 13-inch baking pan, or line it with parchment paper for easy removal. This step helps ensure your cake comes out perfectly.
Mix Dry Ingredients: In a large mixing bowl, whisk together 2 cups all-purpose flour, 2 cups granulated sugar, ½ cup unsweetened cocoa powder, 2 teaspoons baking soda, 1 teaspoon baking powder, and ½ teaspoon salt until there are no cocoa clumps remaining. The dry mix should be well-combined for the best texture.
Add Liquid Ingredients: Add 2 large eggs, 1 cup vegetable oil, and 1 cup whole buttermilk to the dry mixture. Whisk together until well combined; it should be smooth and creamy.
Incorporate Hot Coffee: Now, add 1 cup of hot coffee (or hot water), whisking the batter until smooth. Don’t worry if the batter looks thin; it will create a moist cake once baked.
Bake the Cake: Pour the batter into the prepared baking pan. Tap the pan gently on the counter to release any air bubbles. Bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Start checking at the 30-minute mark for the best results.
Cool the Cake: Allow the cake to cool completely in the pan before frosting. This step is crucial; frosting a warm cake can lead to a melty mess!
Create the Frosting: Melt ½ cup (1 stick) salted butter in a saucepan over medium-low heat. Whisk in ⅔ cup unsweetened cocoa powder, cooking over low heat for 2 minutes while stirring constantly—be careful not to let it boil.
Finish the Frosting: Remove the pan from heat, then add 3 cups sifted confectioners’ sugar and ⅓ cup whole buttermilk. Whisk until the mixture is smooth and glossy. Stir in 1 teaspoon vanilla extract. If your icing seems too thick, you can add a bit more buttermilk, one tablespoon at a time.
Frost the Cake: Spread the warm frosting over the cooled cake evenly. Let it set for about 15 to 20 minutes before slicing and serving. The cake is best enjoyed when the frosting is slightly firm but the cake is still moist and soft.

Storing & Reheating

To store your One Bowl Buttermilk Chocolate Cake, keep it in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate it in a covered container for up to a week. You can also freeze individual slices wrapped tightly in plastic wrap, then foil, for up to 3 months. To refresh the cake, simply let it come to room temperature, or you can reheat it gently in the microwave for about 10-15 seconds if you prefer it warm.

Chef’s Helpful Tips

Avoid overmixing the batter; this can make the cake tough. Mix until just combined for the tenderest results.
Remember to use room temperature ingredients wherever possible—especially eggs and buttermilk. This helps create a uniform batter.
If you prefer a less intense coffee flavor, you can pour in ½ cup of hot water instead; the chocolate will still shine.
For an added kick, consider folding in a handful of chocolate chips or nuts before baking.
Always check for doneness a few minutes before the recommended time—ovens can vary. The edges should be set, and the center should spring back when touched.

There’s something delightfully simple yet deeply satisfying about a homemade cake, and this One Bowl Buttermilk Chocolate Cake truly captures that essence. The combination of rich chocolate and tender crumb is unforgettable. Experiment with your variations, whether it’s adding a sprinkle of sea salt on top or trying different frostings. Enjoy the delightful process of baking; it’s as much about the journey as it is about the sweet treat at the end!

Recipe FAQs

Can I use a different type of pan?

You can definitely use a different pan, but baking times may vary. If you’re opting for round cake pans, adjust the bake time to around 25-30 minutes. Always check for doneness with a toothpick!

How should I store leftovers?

Store any leftover cake in an airtight container at room temperature for up to 3 days. If you have a lot left, refrigerate it for freshness or freeze individual slices for up to 3 months.

Can I make this cake ahead of time?

Absolutely! This cake can be made a day in advance. Just wait until it has cooled completely, then store it covered. Frost just before serving to keep that freshly-decorated appeal.

What can I use if I don’t have buttermilk?

If you don’t have buttermilk, you can easily make a substitute by adding 1 tablespoon of vinegar or lemon juice to 1 cup of milk. Let it sit for a few minutes before using; it thickens and curdles slightly, mimicking buttermilk’s character.
