This Chocolate Cake Recipe delivers a moist, fudgy crumb with deep cocoa flavor and a rich chocolate finish. It suits anyone who wants a bakery-style dessert with simple steps, and it takes about 1 hour total, including 30 to 35 minutes of baking. I baked this for my college roommates years ago, and they still text me for a slice on their birthdays.
Why You Should Try This Chocolate Cake Recipe
This Chocolate Cake Recipe uses oil, buttermilk, and hot coffee to lock in moisture and boost chocolate intensity. You mix it in one bowl, skip fancy tools, and slice neat, tall layers that taste like a special occasion.
The cake stayed moist for three days and tasted even better on day two, which shocked my entire dessert roster ★★★★★
Ingredients You’ll Need
- All-purpose flour: 2 cups or 240 g
- Granulated sugar: 2 cups or 400 g
- Unsweetened cocoa powder: 3/4 cup or 75 g (natural cocoa gives classic flavor; Dutch-process gives deeper color and smooth taste; both work here)
- Baking powder: 1.5 tsp
- Baking soda: 1.5 tsp
- Fine sea salt: 1 tsp
- Instant espresso powder: 1 tsp optional (intensifies chocolate)
- Eggs: 2 large at room temperature
- Buttermilk: 1 cup (pantry swap: add 1 tbsp white vinegar or lemon juice to a cup of milk and rest 5 minutes)
- Neutral oil: 1/2 cup (canola, vegetable, or light olive)
- Pure vanilla extract: 2 tsp
- Hot coffee: 1 cup strong brewed (pantry swap: hot water plus 1 tsp espresso powder, or just hot water)
Chocolate buttercream frosting:
- Unsalted butter: 1 cup or 2 sticks, room temperature
- Powdered sugar: 3 to 3.5 cups, sifted
- Unsweetened cocoa powder: 1/2 to 3/4 cup, sifted
- Heavy cream or milk: 1/3 to 1/2 cup
- Pure vanilla extract: 1 tsp
- Fine sea salt: pinch
- Optional boost: 4 oz dark chocolate, melted and cooled
Shortcuts and notes:
- Pantry shortcut: use a tub of chocolate frosting if the clock runs tight.
- Brand notes: Ghirardelli, Guittard, or Hershey’s cocoa all give solid results.
- Dietary swaps: use a 1:1 gluten-free flour blend with xanthan gum; for dairy-free, use oat or almond milk soured with vinegar and a dairy-free butter for frosting.
Equipment:
- Two 8-inch or 9-inch round cake pans
- Parchment rounds
- Large mixing bowl and whisk
- Hand mixer or stand mixer for frosting
- Cooling racks, offset spatula, and serrated knife for leveling
How to Make Chocolate Cake Recipe
Prep the pans and oven
- Heat the oven to 350°F. Grease two round pans, line the bottoms with parchment, then dust sides with cocoa powder.
- Set the pans on a sheet pan if your oven runs hot for easy rotation.
Mix the batter
- In a large bowl, whisk flour, sugar, cocoa, baking powder, baking soda, salt, and espresso powder.
- In a second bowl, whisk eggs, buttermilk, oil, and vanilla until smooth.
- Pour wet ingredients into dry. Stream in hot coffee while whisking until the batter turns glossy and thin. Expect a thin batter; that signals moisture.
Bake the layers
- Divide batter evenly between pans. Tap pans lightly to pop big bubbles.
- Bake 28 to 32 minutes for 9-inch pans or 32 to 35 minutes for 8-inch pans, until a toothpick comes out with a few moist crumbs.
- Set pans on a rack for 10 minutes.
Cool and frost
- Turn cakes out, peel parchment, and cool completely, about 1 hour.
- Make frosting: beat butter until creamy, 2 minutes. Add powdered sugar and cocoa in stages, mixing on low. Stream in cream, then beat on medium-high until fluffy, 2 to 3 minutes. Beat in vanilla, salt, and melted cooled chocolate if using.
- Level domes if needed. Add a thin crumb coat, chill 15 minutes, then finish with a thicker coat. Swirl the top like you mean it.
Tips & Tricks
- Weigh ingredients for best texture.
- Use hot coffee to bloom cocoa and deepen flavor.
- Bring eggs and buttermilk to room temperature so the batter emulsifies fast.
- Line pans with parchment to prevent sticking.
- Pull cakes when the center springs back and crumbs cling to a toothpick; dry picks signal overbake.
- Chill the crumb coat so final frosting goes on smooth.
- Slice cleanly with a warm knife; wipe between cuts.
- Convert to cupcakes: fill liners two-thirds full and bake 18 to 20 minutes, yield about 24.
What to Serve with Chocolate Cake Recipe
Serve this moist chocolate cake with cold milk, a double espresso, or a glass of cabernet if you like a grown-up pairing. Add a scoop of vanilla ice cream, fresh raspberries, or a swipe of salted caramel sauce. Sprinkle flaky salt on the frosting to make the chocolate pop. If a stray spoon of frosting never reaches the cake, your secret stays safe here.
Make-Ahead and Storage
Bake cake layers up to 2 days ahead. Wrap each cooled layer tightly in plastic and store at room temperature for 1 day or in the fridge for 3 days.
Freeze unfrosted layers for up to 2 months; wrap in plastic, then foil. Thaw wrapped layers in the fridge overnight or on the counter for 1 to 2 hours.
Keep a frosted cake covered in the fridge for up to 4 days. Bring slices to room temperature for 30 to 45 minutes, or warm a slice in the microwave for 10 to 15 seconds for that fresh-baked vibe.

Ingredients
Instructions
- Heat the oven to 350°F (175°C). Grease two 8-inch or 9-inch round cake pans, line the bottoms with parchment rounds, then dust the sides with cocoa powder.
- Set the pans on a sheet pan if your oven runs hot to make rotation easier.
- In a large bowl, whisk together the flour, granulated sugar, cocoa powder, baking powder, baking soda, salt, and instant espresso powder until well combined.
- In a second bowl, whisk the eggs, buttermilk, neutral oil, and vanilla extract until smooth.
- Pour the wet ingredients into the dry ingredients. While whisking, slowly stream in the hot coffee and whisk until the batter is glossy and thin. A thin batter is normal and signals a moist cake.
- Divide the batter evenly between the prepared pans and tap the pans lightly on the counter to release any large air bubbles.
- Bake 28 to 32 minutes for 9-inch pans or 32 to 35 minutes for 8-inch pans, or until a toothpick inserted in the center comes out with a few moist crumbs attached.
- Transfer the pans to a cooling rack and let the cakes cool in the pans for 10 minutes.
- Turn the cakes out onto cooling racks, peel off the parchment, and let cool completely, about 1 hour.
- To make the frosting, beat the butter with a hand mixer or stand mixer on medium speed until creamy, about 2 minutes.
- Add the powdered sugar and cocoa powder in stages, mixing on low speed until incorporated.
- Slowly stream in the heavy cream or milk, then increase the speed to medium-high and beat until the frosting is light and fluffy, 2 to 3 minutes.
- Beat in the vanilla extract, salt, and melted cooled dark chocolate if using.
- If the cake layers are domed, level them with a serrated knife. Place one layer on a serving plate, add frosting, and spread evenly. Top with the second layer.
- Apply a thin crumb coat of frosting over the entire cake and chill for about 15 minutes to set. Finish with a thicker, even coat of frosting and swirl the top as desired.
