- Total: 1 hr
- Servings: 24
- Yield: Two 9-inch round cake layers
Ingredients
- 2 cups white sugar
- 1 ¾ cups all-purpose flour
- ¾ cup unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup milk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup boiling water
- Butter or nonstick spray + flour for the pans
- Your favorite frosting, for topping (optional)
Kitchen Tools
- Large mixing bowl
- Measuring cups & spoons
- Whisk or electric mixer
- Rubber spatula
- Two 9-inch round cake pans
- Cooling rack
- Knife & offset spatula (for frosting, optional)
Step-by-Step Instructions
- Prep: Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans and line the bottoms with parchment if you like easy release. Bring 1 cup of water to a boil while you gather ingredients
- Mix dry & wet: In a large bowl, whisk together sugar, flour, cocoa, baking powder, baking soda, and salt. Add eggs, milk, oil, and vanilla; beat on medium speed for about 2 minutes until smooth and glossy
- Thin the batter: Stir in the boiling water (the batter will be thin that’s what makes it so moist). Divide the batter evenly between the prepared pans, smoothing the tops with a spatula.
- Bake & cool: Bake 30–35 minutes, or until a toothpick in the center comes out clean. Cool in pans 10 minutes, then transfer to a wire rack to cool completely. Frost, slice, and enjoy every chocolatey bite
Pro Tips
- Storage: Store frosted cake covered at room temperature for up to 3–4 days if using buttercream. If using cream cheese frosting, refrigerate within 2 hours and enjoy within 4 days.
- Subs: Swap milk for buttermilk for extra tenderness. Use any neutral oil (canola, sunflower). Try dark cocoa powder for a deeper, more “bakery-style” chocolate flavor.
- Meal Prep: Bake the layers a day ahead, wrap well, and chill before frosting. You can also freeze unfrosted layers up to 3 months for ultra-fast party prep.
- Serving: Serve with fresh berries, a scoop of vanilla ice cream, or a drizzle of warm chocolate sauce for an extra indulgent dessert plate.
Main Body
This one bowl chocolate cake is the kind of recipe every home baker loves having in their back pocket. It uses pantry staples, comes together in minutes, and bakes into layers that are soft, fluffy, and full of deep chocolate flavor. Because everything is mixed in a single bowl, there’s less to wash and less to worry about, which makes it ideal for busy weeknights, last-minute birthday cakes, or school bake sales. You get that “from scratch” taste and texture without the stress.
The secret to the texture is the thin batter. After you mix the sugar, flour, cocoa, leaveners, and salt with the eggs, milk, oil, and vanilla, you stir in very hot boiling water. At this stage the batter might look too runny, but don’t panic that’s exactly what you want. The hot water blooms the cocoa, intensifying the chocolate flavor, and the looser batter bakes up into a tender, moist crumb instead of a dense cake. Just pour slowly into your pans and let the oven do the rest.
Each ingredient has a job here. Vegetable oil, instead of butter, keeps the cake moist even after a day or two on the counter. The combination of baking powder and baking soda gives the layers a beautiful rise without making them dry. Cocoa powder provides rich chocolate flavor without making the cake overly sweet, so it pairs wonderfully with a variety of frostings from ultra-chocolatey to tangy cream cheese. Milk adds tenderness and just enough richness to keep every bite soft.
Once your layers are baked and cooled, you can dress this cake up or down depending on the occasion. For a simple family dessert, a light dusting of powdered sugar is lovely. For birthday parties and celebrations, go all out with a thick swirl of chocolate buttercream and colorful sprinkles. If you’re entertaining, slice each piece neatly and serve on white plates with a few fresh berries on the side for a polished, Pinterest-ready presentation. Because the recipe yields two 9-inch layers, it easily feeds a crowd.
If you’re planning ahead, this recipe is also incredibly freezer-friendly. Bake the layers, cool them completely, then wrap tightly in plastic wrap and a second layer of foil. Freeze for up to three months. When you’re ready to assemble, thaw in the fridge overnight, unwrap, and frost while the layers are still slightly chilled for fewer crumbs. This simple make-ahead trick turns hectic celebration days into relaxed, enjoyable moments you’ve already done most of the work.
Variation Recipes
- Mocha One Bowl Chocolate Cake: Replace part or all of the boiling water with hot brewed coffee or espresso (or decaf) for a gentle mocha flavor that enhances the chocolate without making the cake taste like coffee.
- Chocolate Sheet Cake: Bake the batter in a greased 9×13-inch pan for about 30–35 minutes. Frost directly in the pan for an easy-to-transport dessert that’s perfect for potlucks and classroom treats.
- Peanut Butter Cup Twist: Stir ½ cup mini chocolate chips into the batter and top the cooled cake with peanut butter frosting. The combination of chocolate and peanut butter gives fun, candy bar vibes with almost no extra work.
