Ingredients for alton brown devil's food cake
These carefully measured ingredients create Alton Brown's legendary fudgy, moist devil's food cake layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Softened to room temperature |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smoothness |
| Dark Brown Sugar 🍚 | ½ cup | Packed firmly for moisture |
| Buttermilk 🥛 | 1 cup | Full-fat for best texture |
| Sour Cream 🍦 | ½ cup | Full-fat for moisture retention |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for lightness |
| Cocoa Powder 🍫 | ¾ cup | Dutch-processed for smoothness |
| Baking Powder 🧂 | 1 ½ tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher |
| Hot Water 💧 | ¼ cup | For dissolving cocoa |
| Vegetable Oil 🫒 | ¼ cup | Light, neutral flavor |
The butter and sugars are non-negotiable here—unsalted butter is a must for flavor control, and superfine sugar dissolves better for a smoother batter. I always grab Land O'Lakes unsalted butter from the grocery store's baking aisle—it's reliable and affordable. For cocoa powder, Hershey's Special Dark is my go-to, but Valrhona takes it to the next level if you're feeling fancy. The buttermilk and sour cream work together like a dream—they're what make this cake stay moist for days, not hours. Pro tip: measure your buttermilk in a liquid measuring cup after letting it sit for 10 minutes to ensure it's thick enough.
No buttermilk? Substitute with 1 cup milk + 1 tbsp vinegar, let it sit for 5 minutes. Running short on sour cream? Greek yogurt at half the amount works in a pinch. The eggs need to be room temperature—pop them in warm water for 5 minutes if they're straight from the fridge. For the vanilla, pure Madagascar extract has that complex, rich flavor, but imitation works if that's what you've got. The cocoa powder can be tricky—if you're using natural cocoa, expect a slightly tangy flavor. Dutch-processed keeps it smooth and sweet. And if you're feeling adventurous, swap half the all-purpose flour for cake flour for even lighter layers.
This batter is best used fresh, but you can prep it a day ahead and refrigerate it—just let it sit at room temperature for 30 minutes before baking. The cake keeps beautifully wrapped at room temperature for 3 days, or you can freeze it for up to 3 months. To reheat, wrap a slice in a damp paper towel and microwave for 10 seconds. Trust me, the first bite out of the fridge is still amazing. I like to make two 8-inch layers at a time—perfect for a small gathering or a special occasion. The secret to clean layers? Don't overmix the batter, and let the cake cool completely before frosting.

Step-by-step instructions for Alton brown's devil's food cake
Here's how to bake layers so rich and moist they'll disappear faster than you can say "fudgy perfection."
Create the Moisture Base
In a medium saucepan, combine the 0.25 cup hot water and 0.75 cup cocoa powder. Whisk vigorously until completely smooth—no lumps allowed. This mixture should resemble thin batter. Let it cool to room temperature while you prepare the rest of the ingredients. The hot water helps dissolve the cocoa fully, creating a velvety texture that's the secret to that signature moistness.
In a separate large mixing bowl, cream together the 1 cup unsalted butter, 2 cups granulated sugar, and 0.5 cup dark brown sugar on medium speed until light and fluffy, about 3-4 minutes. You'll notice the mixture nearly doubles in volume and becomes pale. This step incorporates air, which helps create those tender layers. Scrape down the sides of the bowl occasionally to ensure even mixing.
Combine Wet Ingredients
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 2 teaspoons vanilla extract and the cooled cocoa mixture. Mix until just combined—don't overbeat. In a separate bowl, whisk together the 1.5 cups all-purpose flour, 1.5 teaspoons baking powder, and 0.5 teaspoon salt. Sift this dry mixture directly into the wet ingredients and gently fold together using a spatula.
Here's the moisture trick: Add the 1 cup buttermilk and 0.5 cup sour cream all at once. Mix on low speed just until incorporated—overmixing develops gluten, which makes the cake tough. The buttermilk and sour cream work together to keep this cake moist for days. The batter should be thick but pourable, with a few streaks of flour visible. If it's too thick, add 1 tablespoon of the vegetable oil to help with moisture and tenderness.
Divide and Bake the Layers
Preheat your oven to 350°F and grease two 8-inch round cake pans thoroughly, then line the bottoms with parchment paper. Divide the batter evenly between the pans. Tap each pan firmly on the counter 3-4 times to remove any air bubbles and ensure even layers. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with moist crumbs but no wet batter.
I always check for doneness at the 25-minute mark—your oven might run hot, so start checking early. The edges should be pulling away from the pan slightly, and the top should be set but still slightly springy to the touch. Rotate the pans halfway through baking for even browning. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
Assemble with Buttercream Filling
While the layers cool, prepare a simple buttercream filling by beating the 0.25 cup vegetable oil and remaining 0.5 cup unsalted butter (if you set aside any) with 1 cup powdered sugar and 1 teaspoon vanilla extract until smooth and fluffy. For extra moisture, you can also add 1-2 tablespoons of milk if needed.
Once completely cool, level the tops of your cake layers if needed. Place one layer on a cake stand or plate and spread a generous amount of the buttercream. Top with the second layer and spread more buttercream on top and around the sides. Dust with a light layer of cocoa powder for that classic devil's food look. The buttercream should be thick enough to hold the layers together but still spreadable—adjust the powdered sugar amount if needed.
Pro Tips For Making Alton Brown Devil'S Food Cake
- Cream Butter Slowly: Alton’s recipe calls for creaming butter and sugars—don’t rush this. Use a stand mixer on medium speed for 3-4 minutes until the mixture is pale yellow and fluffy, not just combined. I learned this the hard way after skipping it; the cake turned dense and dry. ---
- Measure Buttermilk Right: Buttermilk curdles if overmixed, and this recipe relies on it for moisture. Add it to the dry ingredients in two additions, gently folding just until incorporated. If your buttermilk looks thin, skip the sour cream—it’ll add enough tang without extra liquid. ---
- Don’t Overbake the Center: The cake’s done when a toothpick comes out with moist crumbs, not clean. Alton’s recipe runs 25-30 minutes, but ovens vary—start checking at 22 minutes. If the edges set too fast, tent foil loosely over the top to slow browning. ---
- Upgrade with Vanilla Bean: The recipe uses vanilla extract, but a scraped vanilla bean makes a real difference. Split one pod, add the seeds to the butter-sugar mix, and steep the pod in the buttermilk for 10 minutes before mixing. It’s extra work, but the flavor is richer.
Creative variations of alton brown devil's food cake
Spiced Orange Twist
Add 1 teaspoon orange zest and 1 tablespoon orange juice to the batter for a bright, citrusy twist that cuts through the richness. I love this variation for springtime celebrations—it’s like a little burst of sunshine in every bite. Pair it with a simple orange glaze made from ½ cup powdered sugar + 1 tbsp orange juice for extra zing. 🍊
Espresso Infusion
For coffee lovers, replace ½ cup of the hot water with freshly brewed espresso when dissolving the cocoa powder. This adds a subtle coffee depth that pairs beautifully with chocolate. I recommend using Starbucks espresso or a high-quality brand for the best flavor. Trust me, this twist makes the cake taste like a decadent dessert from a fancy bakery. ☕
Peanut Butter Swirl
Divide the batter into two bowls, then stir ½ cup creamy peanut butter into one portion. Spread half of the plain batter into your prepared pans, then dollop spoonfuls of the peanut butter batter on top. Swirl with a knife before adding the remaining plain batter. Bake as directed for a marbled effect that’s pure indulgence. Use Jif Natural or Skippy for the best texture. 🥜
Salted Caramel Filling
Skip the buttercream and replace it with a homemade salted caramel filling. Cook ½ cup sugar in a saucepan until amber, then whisk in ¼ cup heavy cream and 2 tbsp butter. Stir in a pinch of flaky sea salt (like Maldon) before it sets. Spread this between layers for a gooey, salty-sweet contrast that’s irresistible. 🍬
White Chocolate Chunk
Fold ½ cup chopped white chocolate into the batter just before baking for pockets of creamy sweetness. I use Ghirardelli white chocolate squares because they melt beautifully. For extra drama, reserve some chopped white chocolate to sprinkle on top before baking—it’ll create stunning golden-brown chunks. This variation feels extra luxurious without being complicated. 🍫
Boozy Cherry Filling
Simmer 1 cup pitted cherries (fresh or frozen) with 2 tbsp brandy or bourbon and 1 tbsp sugar until syrupy. Let cool, then spread between layers for a boozy, fruity surprise. I love using Morello cherries for their deep flavor. Top with a dusting of cocoa powder for a sophisticated finish. 🍒

Frequently asked questions
Why does this devil's food cake stay moist longer than others?
The secret lies in the buttermilk and sour cream combination, which adds moisture without making the cake dense. The hot water dissolved cocoa creates a velvety texture, while the vegetable oil keeps it tender. These ingredients work together to lock in moisture for days, not just hours like traditional recipes.
Can I make this cake in a 9-inch pan instead of 8-inch?
Yes, but reduce baking time to 20-25 minutes—the smaller surface area cooks faster. For best results, use two 9-inch pans with 1 cup batter each (instead of 1.5 cups). The layers will be slightly thinner but still delicious. Always check doneness with a toothpick at the lower end of the time range.
What's the best way to store leftover cake?
Wrap tightly in plastic wrap or aluminum foil and store at room temperature for 3 days, or freeze for up to 3 months. For serving, let it sit at room temperature for 30 minutes before slicing—this prevents crumbs. The moisture trick makes it stay fresh longer than most cakes, but it's still best enjoyed fresh!
Why did my cake crack on top?
This usually happens from overbaking or opening the oven too soon. Check for doneness at 25 minutes—the toothpick test is key. Also ensure your oven is properly calibrated. For extra insurance, place a metal tray on the rack below for even heat distribution. The cracks won't affect flavor, but they can be prevented with proper timing.
Can I substitute Dutch-processed cocoa powder?
Dutch-processed cocoa is actually preferred here—it's smoother and sweeter. If using natural cocoa, expect a slightly tangy flavor and reduce sugar by 1 tablespoon to balance. The hot water trick works best with Dutch-processed, but either will work. For maximum richness, use Hershey's Special Dark or Valrhona brands.
