Ingredients for alton brown devil's food cake
Twelve ingredients, one secret trick—this cake delivers restaurant-quality fudgy layers every time.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Unsalted Butter 🧈 | 1 ¼ cups | Melted and cooled slightly |
| Granulated Sugar 🍚 | 2 cups | Light brown preferred |
| Packed Brown Sugar 🍚 | 1 cup | For moisture and depth |
| Buttermilk 🥛 | 1 cup | Room temperature preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 2 tsp | Pure vanilla preferred |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | High-quality Dutch-processed |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Hot Water 💧 | ½ cup | For dissolving cocoa |
| Vegetable Oil 🫒 | ¼ cup | Light, neutral flavor |
The cocoa powder is your game-changer here. Hershey's Special Dark or Dutch-processed brands from the baking aisle work best—they dissolve smoothly for that velvety texture. Brown sugar isn't just for flavor; it's your moisture secret. Domino or C&H brands pack perfectly, and you'll notice the difference when your cake stays tender for days. The buttermilk? Don't grab the carton—look for cultured buttermilk at specialty stores or make your own with milk and vinegar. And that melted butter? Cool it just until it's warm to the touch—room temp makes it too thick to mix properly.
No buttermilk? Mix 1 cup milk + 1 tbsp vinegar and let sit 5 minutes. Short on brown sugar? White sugar + 1 tbsp molasses gets you close. The eggs should be room temp—cold ones make the batter lumpy. Can't find Dutch-processed cocoa? Natural cocoa works too, but add an extra 1/4 tsp baking powder to compensate. And that vegetable oil? Avocado oil is my go-to—neutral flavor, stays liquid longer than butter. The secret moisture trick? The buttermilk and melted butter combo keeps this cake moist for 5 days without drying out.
This batter needs to rest 30 minutes before baking—trust me on this. It gives the flour time to hydrate fully, which prevents cracking. Store leftover cake in an airtight container with a slice of bread to keep it fresh. The layers stay perfect for 4 days at room temp or 1 week in the fridge. Freeze slices wrapped in plastic for 3 months—they reheat beautifully in the oven for 10 minutes at 300°F. And that melted butter trick? It's what makes this cake taste homemade, not boxed.

Step-by-step instructions for Alton Brown's devil's food cake
Here's how to create layers that stay moist for days—no dry crumbs in sight.
Mix Dry Ingredients for Perfect Texture
In a large bowl, whisk together the 2.5 cups All-Purpose Flour, 2 tsp Baking Powder, and 0.5 tsp Salt. Sift the 0.75 cup Unsweetened Cocoa Powder directly over the dry ingredients and whisk until fully combined. This ensures even distribution and prevents clumping in the final batter.
I always sift the cocoa powder first—it's lighter and absorbs moisture better when incorporated this way. Set the dry mixture aside for now; we'll combine it with wet ingredients next. The key here is to keep everything separate until the very last moment to maintain the cake's moisture.
Combine Wet Ingredients for Maximum Moisture
In a separate large bowl, beat the 1.25 cups Unsalted Butter (melted and cooled slightly) with the 2 cups Granulated Sugar and 1 cup Packed Brown Sugar on medium speed until light and fluffy—about 3-4 minutes. This step is crucial for creating air pockets that make the cake tender rather than dense.
Add the 2 whole Large Eggs, one at a time, beating well after each addition. Stir in the 2 tsp Vanilla Extract and 0.25 cup Vegetable Oil. The oil helps keep the cake moist, while the vanilla adds that signature depth. I like to use room-temperature eggs—they incorporate more smoothly and create a lighter batter.
Create the Secret Moisture Trick
In a small bowl, whisk together the 1 cup Buttermilk and 0.5 cup Hot Water. This combination is the secret to that signature Alton Brown moisture—it creates steam during baking that keeps the cake tender for days. Gradually add this mixture to the wet ingredients while mixing on low speed.
With the mixer still running on low, slowly add the dry ingredients from Step 1. Mix just until combined—overmixing develops gluten and makes the cake tough. The batter should be thick but pourable. Here's the thing—don't worry if it looks too thick. This is exactly what we want for that fudgy texture and perfect moisture level.
Bake in Layers for Perfect Height
Preheat your oven to 350°F. Grease and flour three 8-inch round cake pans (or use nonstick spray). Divide the batter evenly among the pans—you should have about 1 cup batter per pan. Tap each pan gently on the counter to remove any air bubbles.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The edges should be set but the center should still be slightly springy. I know it seems counterintuitive, but slightly underbaking ensures maximum moisture. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Frost and Assemble for Ultimate Richness
Once completely cooled, level the tops of the cakes if needed. For the ultimate devil's food experience, spread a layer of your favorite chocolate buttercream between each layer. I like to use a simple 3:2:1 ratio—3 parts buttercream, 2 parts powdered sugar, and 1 part cocoa powder—whipped to fluffy perfection.
Frost the top and sides of the cake with remaining buttercream. The layers should be visible through the frosting—that's the hallmark of a proper devil's food cake. Chill for at least 1 hour before slicing to let the frosting set. This cake stays moist for days, but trust me, it won't last that long with how rich it is!
Pro Tips For Making Alton Brown Devil'S Food Cake
- Whisk Butter & Sugar First: I learned this the hard way—skipping the creaming step leaves your cake dense and dry. Beat the butter, granulated sugar, and brown sugar together until light and fluffy (about 3-5 minutes), not just combined. That air incorporates into the batter, giving you that signature tender crumb. ---
- Measure Flour Right: Spooning flour into cups and packing it down? Stop. Use a kitchen scale if you can—this recipe relies on precise ratios. If you must use cups, fluff the flour first, then scoop and level. Overpacking makes the cake tough; under-measuring leaves it cakey. ---
- Don’t Overmix the Buttermilk: Stir the buttermilk into the dry ingredients just until combined—lumps are fine. Overmixing develops gluten, turning your rich devil’s food into a dense brick. Fold it in like you’re tucking in a blanket, not kneading bread dough. ---
- Rotate the Pan Mid-Bake: This recipe bakes unevenly if you ignore the oven’s hot spots. After 20 minutes, swap the pan from top to bottom rack (or front to back if your oven runs hot on one side). No thermometer? Check the edges—when they’re set but the center still jiggles slightly, you’re golden.
Pro cooking tips for this recipe
Batter Resting Matters
Let the batter rest for 30 minutes before baking—this is non-negotiable. The flour needs time to fully hydrate, preventing cracks and ensuring maximum moisture. I've seen home bakers skip this step, only to end up with dense, dry layers. Trust me, the extra wait pays off with a cake that stays tender for days. 💫
Pan Prep is Critical
Grease your 8-inch round pans with butter and dust with flour, tapping out excess. I use nonstick spray> as a backup for extra insurance. The pans should be room temperature—cold pans cause uneven baking. Line the bottoms with parchment circles if you're worried about sticking, but I've never had issues with properly greased pans.
Underbake for Moisture
Pull your cakes out when the center still has a slight spring to it—about 30-35 minutes at 350°F. A toothpick should come out with moist crumbs, not dry ones. This underbaking trick is what keeps the cake fudgy and prevents that dry, crumbly texture. Let them cool in the pans for 10 minutes> before transferring to a rack.
Buttercream Ratio Secrets
For that signature Alton Brown buttercream, use a 3:2:1 ratio> of buttercream base to powdered sugar to cocoa powder. Whip it until light and fluffy—about 3-4 minutes> with a stand mixer. The cocoa powder gives it that rich chocolate depth without overpowering. I like to add 1 tsp vanilla extract> to the mix for extra flavor complexity.
Frosting Chill Time
Never skip the 1-hour chill> before slicing. This allows the frosting to set properly and prevents a messy cake. I've made this mistake—trust me, it's not pretty. The cake will hold its shape better, and the layers will stay intact. If you're in a hurry, pop it in the fridge for 30 minutes> minimum, but 1 hour is ideal.
Storage Hacks for Freshness
Store your cake in an airtight container with a slice of bread to absorb moisture and keep it fresh. At room temperature, it stays perfect for 4 days>, while the fridge extends that to 1 week>. For longer storage, freeze slices wrapped in plastic for up to 3 months>. To reheat, bake at 300°F> for 10 minutes>—it comes out just like fresh!

Frequently asked questions
Why does this devil's food cake stay moist longer than others?
The secret lies in the buttermilk and hot water combination—this creates steam during baking that keeps the layers tender for days. The melted butter and vegetable oil also add extra moisture without making the cake greasy. Unlike traditional recipes, we avoid overmixing to preserve the cake's delicate crumb structure.
Can I make this cake in a different pan size?
Yes! For 9-inch pans, reduce batter by 25% per pan (about 3/4 cup each). For 6-inch pans, increase to 1.5 cups per pan. Always adjust baking time—smaller pans bake 5-10 minutes longer, while larger ones may need 5 minutes less. The key is to pull them when a toothpick comes out with moist crumbs.
What's the best way to level the cake layers?
Use a serrated knife or cake leveler for clean cuts. Dip the blade in hot water between slices to prevent sticking. For perfect results, chill the cake 15 minutes in the freezer first—this makes leveling easier and prevents crumbs. The goal is smooth, even layers for that professional look.
Can I substitute buttermilk if I don't have any?
Mix 1 cup milk + 1 tbsp vinegar or lemon juice, let sit 5 minutes until thickened. For a richer flavor, use 1 cup sour cream + 1 tbsp milk instead. The acidity is crucial for that signature moisture—don't skip it! The cake will still turn out delicious but may be slightly denser.
How do I fix cracked cake layers?
Cracks usually happen from overmixing or not letting the batter rest. For minor cracks, simply frost over them—they'll disappear! For severe cracks, use a spatula to gently press the edges back together before frosting. The secret moisture trick actually helps prevent cracks, but even if they appear, this cake is still delicious with proper frosting.
