One Bowl Chocolate Cake
This One Bowl Chocolate Cake is nearly as easy to make as a boxed mix. This simple, classic recipe results in a perfect chocolate cake every time!
For another easy, homemade chocolate treat, try my recipe for Classic Fudge Walnut Brownies—they’re simple to make and packed with rich, fudgy goodness.
This is my go-to easy chocolate cake recipe that I’ve made countless times over the years for birthdays, summer parties, and pretty much any other excuse I can think of. Most recently, it was a much needed comforting dessert that we delivered to my my son and daughter-in-law after they welcomed our new baby grandson into the family.
If you know me well, you’ve had this cake.
In addition to being our family’s favorite chocolate cake, this One Bowl Chocolate Cake recipe has a seriously no-fuss method that I love. All you’ll need is a large bowl, an electric mixer, and a few minutes on your hands to get it in the oven.
The fudgy chocolate icing is made quickly on the stove and seals the deal in the most delicious way.
Ingredient Notes
- Dry ingredients: All-purpose flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt.
- Wet ingredients: Eggs, buttermilk, vegetable oil, pure vanilla extract, and some very hot water.
- Chocolate icing: Butter, unsweetened cocoa powder, powdered sugar, and a little additional buttermilk and pure vanilla extract. From time to time, I will add some finely chopped pecans or walnuts. Nuts are totally optional.
Variation
For something a little different, try using hot brewed coffee in place of the hot water. Coffee naturally intensifies the richness of cocoa, making the chocolate taste deeper and more complex. It enhances the chocolate flavor without making the cake taste like coffee.
How to Make One Bowl Chocolate Cake
This is a quick overview of how to make this recipe. You’ll find detailed instructions and a video in the recipe card at the end of this post.
- Whisk together the dry ingredients in a large mixing bowl. Then, add the wet ingredients and mix with an electric hand mixer until combined. You could do this all in the bowl of your stand mixer if you’d like.
- Add the very hot water and mix again briefly until combined. The cake batter will be quite thin.
- Transfer the batter to a 9- x 13-inch baking pan (glass or metal) that has been coated with nonstick cooking spray.
- Bake at 350 degrees F for 35 to 40 minutes or until a toothpick inserted in the center comes out clean.
If you’re making this cake to deliver to a friend or family member, bake it in a 9- x 13-inch disposable aluminum foil cake pan with a lid. Or be like me and divide it between two 8-inch foil pans so you can give one away and keep one for yourself! The baking time can differ slightly when you use foil pans so just watch it carefully towards the end of the baking time.
The Fudgy Chocolate Icing
- In a large saucepan, whisk melted butter with the cocoa powder, buttermilk and vanilla.
- Reduce the heat and whisk in powdered sugar, using as much as you need until you’ve reached the desired consistency. It should be thick but pourable.
- Continue whisking vigorously until smooth. This is where you would stir in chopped nuts, if you want a nutty frosting, or reserve them to use as a garnish on top.
- Immediately pour the icing over the cake and use an offset spatula or butter knife to spread it out evenly over the surface. Allow the icing to set for a few minutes before slicing and serving the cake.
Alternate Layer Cake and Cupcake Instructions
I nearly always use a 9- x 13-inch pan for this recipe but it works well as round layer cake too.
- Divide the batter between two greased 9-inch round cake pans. Bake at 350 degrees for 28 to 32 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely before frosting.
I frost my round cakes with a sturdier, buttercream-style frosting which works better for a layer cake than a thinner icing. I’ve even been known to buy a tub of chocolate fudge frosting from the store (gasp!) to make it super easy. No one will ever know!
Want to make cupcakes? No problem!
- Grease or line your cupcake pan with liners, and fill each cup about two-thirds full with cake batter.
- Bake your cupcakes at 350 degrees F for about 18 to 22 minutes. Allow them to cool in the pan for about 10 minutes, then remove to a wire rack to cool completely before frosting.

Instructions
For the Cake
Preheat oven to 350 degrees F. Coat a 9- x 13-inch baking dish with nonstick cooking spray.

Pour the batter into the prepared baking dish. Bake for 35 to 40 minutes or until a toothpick inserted in center comes out clean. Cool completely in the pan before frosting.
For the Icing
Melt butter in a large saucepan over MEDIUM heat. Whisk in the cocoa powder, buttermilk and vanilla. Turn the heat to LOW and whisk in the powdered sugar, using as much as you need until you’ve reached the desired consistency. It should be thick but pourable. Continue whisking vigorously until smooth. Stir in chopped nuts, if using, or reserve them to use as a garnish on top.
Immediately pour the icing over the cake and use an offset spatula or butter knife to spread it out evenly over the surface. Garnish with nuts, if desired. Allow to set for a few minutes before slicing and serving the cake.
Notes
Store the cake, covered, at room temperature and consume within 2 to 3 days for the best quality.

Make and Take Directions
If you’re making this cake to deliver to a friend or family member, bake it in a disposable 9- x 13-inch aluminum foil cake pan with a lid.
