Ingredients for buzzfeed chocolate cake
Twelve simple ingredients transform into BuzzFeed’s iconic one-bowl chocolate cake with coffee depth.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for perfect texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Melted, cooled slightly |
| Instant Coffee Granules ☕ | 2 tbsp | High-quality for deep flavor |
| Espresso Powder ☕ | 1 tbsp | Enhances chocolate depth |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Natural or Dutch-processed |
| Large Eggs 🥚 | 2 whole | Room temperature for mixing |
| Vanilla Extract 🌸 | 1 tbsp | Pure, high-quality extract |
| Baking Soda 🧂 | ½ tsp | Freshly measured |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Whole Milk 🥛 | ¾ cup | Room temperature |
| Vegetable Oil 🫒 | ¼ cup | Light, neutral flavor |
The cocoa powder is non-negotiable—Hershey’s Special Dark or Dutch-processed for that velvety texture. Grab instant coffee from Starbucks or Folgers for consistency, and espresso powder from Lavazza if you want to splurge. The butter? Plugrá or Land O’Lakes work perfectly—just don’t use margarine. For the flour, sift it through a fine-mesh sieve to avoid a dense crumb. Pro tip: measure your dry ingredients by scooping and leveling, not packing the cups.
No instant coffee? Strong brewed coffee cooled works in a pinch, but the granules dissolve better. Skip the espresso powder? Double the instant coffee for a similar kick. Using cake flour? Add 2 tbsp cornstarch to the all-purpose flour for a lighter texture. For a richer flavor, swap half the milk for heavy cream. And if you’re gluten-free, use a 1:1 gluten-free flour blend—just add an extra 0.5 tsp xanthan gum.
This batter keeps in the fridge for up to 24 hours—perfect for overnight prep. Once baked, let the cake cool completely before slicing, or the layers will crumble. Store wrapped in plastic at room temperature for 3 days, or freeze slices for up to 3 months. The crackly top? That’s your sign it’s ready—just don’t skip the cooling step. And trust me, the coffee notes get even better the next day!

The butter gets creamed with sugar in minutes, and the coffee granules dissolve right into the wet ingredients. Honestly, it’s the kind of cake that makes me feel like a baking pro without the fuss.

Plus, it keeps well for days, so you’re not scrambling to use it all up. My wallet—and my taste buds—thank me every time.
Step-by-step instructions for one-bowl fudgy chocolate cake
This cake comes together in one bowl with rich layers of chocolate and coffee flavor—no mixer required!
🍳 Step 1: Melt Butter and Combine Wet Ingredients
In a large microwave-safe bowl, melt the 1 cup unsalted butter in 30-second intervals, stirring between each until completely smooth. Let it cool for 2 minutes—it should be warm to the touch but not hot. Add the 2 cups granulated sugar, 2 whole large eggs, 1 tbsp vanilla extract, 0.75 cup whole milk, 0.25 cup vegetable oil, 2 tbsp instant coffee granules, and 1 tbsp espresso powder.
Whisk vigorously for 2 minutes until the mixture is completely smooth and all the sugar dissolves. Here's the thing—this step ensures your cake won't be grainy. The coffee granules and espresso powder will dissolve completely, giving that signature BuzzFeed coffee kick without bitterness.
👨🍳 Step 2: Sift Dry Ingredients and Fold Gently
In a separate bowl, sift together the 2 cups all-purpose flour, 0.75 cup unsweetened cocoa powder, 0.5 tsp baking soda, and 0.5 tsp salt. I use a fine-mesh sieve for this—it prevents lumps and ensures even distribution of the cocoa. Gently fold the dry ingredients into the wet mixture using a spatula, being careful not to overmix. You'll see streaks of flour at first—that's normal and actually desirable for a tender crumb.
Stop mixing as soon as the flour disappears. Overmixing develops gluten, which makes cakes tough. The batter should be thick but pourable. If it looks too stiff, add 1-2 tablespoons milk to loosen it. This is the moment that matters: your cake's texture depends on this step.
🔥 Step 3: Bake to Perfectly Fudgy Perfection
Preheat your oven to 350°F and grease two 8-inch round cake pans (or one 9x13-inch pan for a sheet cake). Divide the batter evenly between the pans—you should have about 1 cup batter per pan. Tap the pans gently on the counter to remove any air bubbles.
Bake for 30-35 minutes until a toothpick inserted in the center comes out with moist crumbs but no wet batter. The edges should be pulling away slightly from the pan, and the top should be crackly but not dry. I know it seems weird, but trust me—underbaking just a little keeps that fudgy texture we're after. If the top browns too quickly, tent with foil after 20 minutes.
⏰ Step 4: Cool and Layer for Maximum Moisture
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer to a wire rack to cool completely. Here's the secret to keeping this cake moist: don't skip the cooling step. Rushing this will make your cake dry out faster.
Once completely cool, level the tops if needed, then frost with your favorite chocolate ganache or cream cheese frosting. For extra decadence, add a dusting of cocoa powder or a sprinkle of crushed coffee beans on top. This cake keeps well for 3-4 days covered at room temperature, or you can freeze slices for up to 3 months.
Pro Tips For Making Buzzfeed Chocolate Cake
- MELT BUTTER SLOWLY: I learned this the hard way—dumping cold butter straight into hot liquid makes greasy lumps that ruin texture. Warm the butter in a bowl over barely simmering water (or microwave in 10-second bursts) until it’s just pourable but not greasy. The cake’s crumb will thank you.
- SIFT DRY INGREDIENTS TOGETHER: The BuzzFeed recipe’s coffee and cocoa can clump like a stubborn toddler’s socks. Mix the flour, sugar, coffee granules, and espresso powder in a bowl first, then sift them all at once. This guarantees even distribution—no bitter pockets or dry spots.
- DON’T OVERMIX THE BATTER: I used to beat this batter until it looked like pancake batter, but that’s the fast track to a dense, rubbery cake. Mix just until the flour disappears (about 20 strokes with a spatula). Overmixing develops gluten, and this cake’s magic is in its tender crumb.
- CHILL THE BATTER 10 MINUTES: This isn’t the prettiest method, but it’s the tastiest. After mixing, let the batter sit uncovered in the bowl for 10 minutes. The flour absorbs moisture evenly, and the coffee flavor deepens—no weird science, just better texture. (Yes, even if you’re impatient like me.)
Make-ahead tips for this dish
Batter Prep Ahead
Mix your batter up to 24 hours ahead and store it in an airtight container in the fridge. The flavors meld beautifully overnight, and the coffee notes deepen. When ready to bake, let the batter sit at room temperature for 30 minutes before dividing into pans—this prevents uneven baking.
Honestly, this is my favorite trick for stress-free baking days. 💫
Bake and Freeze
Bake your cakes as directed, then let them cool completely before wrapping tightly in plastic wrap. Place the wrapped cakes in a freezer bag and freeze for up to 3 months.
When ready to serve, thaw at room temperature for 2 hours or microwave for 30 seconds per slice. The texture stays moist even after freezing—no one will guess it was prepped ahead!
Frosting Prep
Make your ganache or frosting the day before and store it in the fridge. This gives you a head start and ensures everything comes together smoothly. For a chocolate ganache, combine 1 cup heavy cream and 8 oz dark chocolate chips, heat until melted, then cool slightly before spreading.
The chilled frosting will be easier to work with and won't melt as you assemble.
Layering for Parties
Assemble your cake layers the night before an event and store it uncovered at room temperature. The top will develop that gorgeous crackly crust overnight, and the flavors will be even more developed.
Cover loosely with a cake dome if needed—just don't seal it completely. This is perfect for birthdays or holidays when you want to impress without last-minute stress.
Portioning for Meal Prep
Slice your cooled cake into individual portions and wrap each slice tightly in plastic wrap. Store in a single-layer container in the freezer for up to 3 months.
To reheat, microwave each slice for 10-15 seconds—just enough to warm through without drying out. These make perfect grab-and-go treats for busy mornings or after-school snacks.
Gift-Worthy Packaging
For a BuzzFeed-worthy presentation, wrap individual slices in parchment paper and tie with twine. Place them in a decorative box or gift bag for the perfect shareable treat. Add a dusting of cocoa powder or crushed coffee beans for extra flair.
This is the kind of dessert people will actually take home and rave about—no plastic containers required! ✨

Frequently asked questions
Why does this recipe use both instant coffee and espresso powder?
The instant coffee granules dissolve completely for smooth flavor, while the espresso powder adds depth without bitterness. Together, they create that signature BuzzFeed coffee-chocolate synergy that elevates this beyond basic chocolate cake. The combination is subtle but makes a huge difference in complexity.
Can I make this cake in a 9x13-inch pan instead of round pans?
For a sheet cake version, use the same batter in a greased 9x13-inch pan and bake for 35-40 minutes at 350°F. The baking time may increase slightly, so check with a toothpick at 30 minutes. This works perfectly for parties or when you want to serve larger portions.
What's the best way to store leftovers to keep them moist?
Wrap cooled slices tightly in plastic wrap and store at room temperature for 3 days, or freeze for 3 months. For reheating, microwave for 10-15 seconds—just enough to warm through without drying. The key is airtight storage and minimal exposure to air, which helps maintain moisture.
How do I fix a cake that's too dense or dry?
Dense cake usually means overmixing or underbaking. For next time, fold dry ingredients just until combined (stop when no flour streaks remain) and bake until a toothpick comes out with moist crumbs. If your cake is already baked too dry, try brushing warm slices with simple syrup (equal parts sugar and water heated until dissolved) to restore moisture.
Can I substitute Dutch-processed cocoa for natural cocoa powder?
Yes, but you may need to adjust slightly. Dutch-processed cocoa (like Hershey's Special Dark) is smoother and more mellow, while natural cocoa (like Hershey's Unsweetened) is more acidic. If using natural cocoa, add 1/4 tsp extra baking soda to balance the acidity. The flavor will be slightly different but still delicious!
