Ingredients
- 1 cup coconut sugar or brown sugar
- 1/4 cup vegetable oil
- 1 egg
- 1/2 cup buttermilk
- 1/2 cup hot brewed coffee
- 2 teaspoons vanilla extract
- 3/4 cup white whole wheat flour
- 1/3 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- FROSTING:
- 1/2 cup coconut sugar or brown sugar
- 1/4 cup unsweetened cocoa powder
- 2 tablespoons cornstarch
- 1/4 teaspoon salt
- 1/2 cup water
- 2 tablespoons butter
- 1 teaspoon vanilla extract
Instructions
-
Preheat oven to 350F (175C). Line the bottom of a 9-inch cake pan with a parchment paper round and lightly grease both the bottom and sides. Set aside.
-
In a large mixing bowl, thoroughly whisk together the coconut sugar (or brown sugar), vegetable oil, egg, buttermilk, hot brewed coffee, and vanilla extract until the mixture is smooth and well combined. Gradually add the white whole wheat flour, unsweetened cocoa powder, baking soda, baking powder, and salt to the wet ingredients. Gently fold everything together until just combined. Be careful not to overmix; the batter will be slightly thin in consistency.
-
Pour the prepared batter evenly into your greased and lined cake pan. Bake the cake at 350F (175C) for 28-30 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs clinging to it. Transfer the cake to a wire cooling rack and allow it to cool completely before inverting it onto a serving plate.
-
To make the frosting: In a small saucepan, whisk together the coconut sugar (or brown sugar), unsweetened cocoa powder, cornstarch, and salt with water until the mixture is smooth. Bring this mixture to a boil over medium heat, stirring constantly, until the frosting thickens and becomes smooth. Remove the saucepan from the heat and whisk in the butter and vanilla extract until fully incorporated and glossy.
-
Allow the chocolate fudge frosting to cool slightly until it reaches a spreadable consistency. Once the cake is completely cooled, generously spread the frosting over the top. Slice, serve, and enjoy your delicious homemade chocolate cake!

Why This Easy Chocolate Cake Will Become Your Go-To
There are countless reasons to fall in love with this one-bowl, single-layer chocolate cake. Beyond its undeniable ease of preparation, its rich flavor profile and tender, moist crumb truly set it apart. The inclusion of hot coffee in the batter doesn’t make the cake taste like coffee; rather, it acts as a flavor enhancer, intensifying the cocoa and creating a deeper, more complex chocolate experience. The buttermilk also plays a crucial role, reacting with the baking soda to ensure a light, airy texture and adding to the cake’s exceptional moisture. This recipe is a fantastic choice for those who want to enjoy the satisfaction of homemade baking without dedicating hours to the kitchen. It’s perfect for last-minute dessert needs, unexpected guests, or simply satisfying that sudden, insistent desire for something sweet and chocolatey. Once you try this fuss-free approach, you’ll wonder why you ever bothered with more complicated recipes.
Tips for Perfecting Your One-Bowl Chocolate Cake
- Don’t Overmix: When combining the wet and dry ingredients, mix just until no dry streaks of flour remain. Overmixing can develop the gluten in the flour too much, leading to a tough cake. A slightly lumpy batter is better than a smooth, overmixed one.
- Use Good Quality Cocoa: The quality of your unsweetened cocoa powder significantly impacts the cake’s chocolate flavor. Opt for a good quality brand for the best results.
- Room Temperature Ingredients (mostly): While many recipes stress room temperature ingredients, for this one-bowl cake, the hot coffee helps integrate everything. However, an egg at room temperature will combine more smoothly with other ingredients.
- Test for Doneness: The suggested baking time is a guideline. Ovens vary, so always rely on the toothpick test. When inserted into the center, it should come out with moist crumbs, not wet batter.
- Cool Completely: Resist the urge to frost a warm cake! The heat will melt the fudge frosting, creating a messy situation. Allow the cake to cool fully on a wire rack before applying your decadent frosting.
Frequently Asked Questions About One-Bowl Chocolate Cake
Q: Can I make this cake without coffee?
A: While hot coffee enhances the chocolate flavor and moisture, you can substitute it with an equal amount of hot water or even hot milk. The chocolate flavor might not be as deep, but the cake will still be delicious.
Q: What if I don’t have buttermilk?
A: No problem! You can easily make a homemade buttermilk substitute. Combine 1/2 cup of regular milk with 1/2 tablespoon of white vinegar or lemon juice. Let it sit for 5-10 minutes until it slightly curdles, then use as directed.
Q: Can I use all-purpose flour instead of white whole wheat flour?
A: Yes, you can substitute all-purpose flour for white whole wheat flour. The cake’s texture might be slightly lighter, but it will still be fantastic. No other adjustments are usually needed.
Q: How should I store this chocolate cake?
A: Store the frosted cake at room temperature, covered, for up to 2-3 days. For longer storage, you can refrigerate it for up to a week. Bring it to room temperature before serving for the best flavor and texture.
Q: Can I freeze this cake?
A: Absolutely! This cake freezes beautifully, both unfrosted and frosted. Wrap unfrosted cake tightly in plastic wrap, then foil, and freeze for up to 2 months. For frosted cake, freeze uncovered until the frosting is firm, then wrap tightly and store. Thaw in the refrigerator overnight or at room temperature for a few hours before serving.
