Ingredients for america's test kitchen chocolate cake
Precision matters here—these ingredients balance richness and moisture for foolproof chocolate cake layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for reverse creaming |
| Granulated Sugar 🍚 | 2 ¼ cups | Superfine preferred for smooth texture |
| Dark Brown Sugar 🍚 | ¼ cup | Packed, for moisture and depth |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Dutch-processed for smoothness |
| All-Purpose Flour 🌾 | 2 cups | Sifted, plus extra for dusting |
| Baking Powder 🍞 | 1 tbsp | Freshly opened for leavening |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Espresso Powder ☕ | 1 tsp | Enhances chocolate flavor |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| Milk 🥛 | ¾ cup | Room temperature, whole preferred |
| Buttermilk 🥛 | ¼ cup | Homemade or store-bought |
| Vegetable Oil 🫒 | ¼ cup | Light, for tenderness |
The cocoa powder is non-negotiable: Dutch-processed delivers that deep, velvety flavor without bitterness. Valrhona or Guittard are my go-tos, but any high-quality brand works—just avoid the baking aisle's bargain bins. The sugars? Superfine granulated dissolves faster, but if you only have regular, pulse it in a food processor for 30 seconds. Brown sugar should be packed tightly—no scooping. For the butter, European-style (like Plugrá) has higher fat content, which enhances richness. Keep it cold when creaming to avoid gluten development.
No buttermilk? Mix 1 tbsp vinegar or lemon juice with 1/4 cup milk, let sit 5 minutes. Out of espresso powder? Strong brewed coffee at half the amount works, but it adds moisture. The vanilla extract is where you can splurge—Madagascar Bourbon has the most complex flavor. For the eggs, separate yolks and whites for the reverse creaming method; this technique creates air pockets that make the cake light. The vegetable oil keeps the crumb tender without adding greasiness—light olive oil is a decent swap if needed.
Store dry ingredients like flour and cocoa powder in airtight containers away from heat sources for up to 6 months. Butter should stay wrapped in its original packaging until used, then transferred to a cool, dry place. The cake layers keep well for 3 days at room temperature, wrapped tightly, or 5 days in the fridge. For longer storage, freeze layers individually (without frosting) for up to 3 months—thaw at room temperature before assembling.
Why You'll Love This Recipe
- No Mixer Needed: This cake comes together with a simple hand-whisked batter—no stand mixer required. I’ve made it in a mug when I was too tired to stand, and it still turns out rich and moist. The secret? Creaming the butter and sugars properly, then folding in that cocoa powder until it’s just combined.
- Deep Chocolate Soul: That combo of dark brown sugar and unsweetened cocoa? It’s like a hug for your taste buds. The brown sugar adds a caramel depth that cuts through the bitterness of the cocoa, while the butter keeps it luscious. Honestly, I’ve had cake purists sniff at “too much sugar,” but this is the kind of indulgence that doesn’t need an apology.
- Birthday to Brunch: Serve it warm with vanilla ice cream for a birthday celebration, or slice it cold for a weekday breakfast with a dollop of whipped cream. I’ve even packed it in my lunchbox—yes, really—because it holds up better than most store-bought versions. The texture stays tender for days, which is a win for me and my forgetful schedule.
- Budget-Friendly Luxury: You’re using pantry staples here: butter, sugar, eggs, and cocoa. No fancy extracts or expensive mix-ins. Between us, this cake costs me about half what a bakery version would, and it’s way better. Plus, the leftovers? They’re my go-to for “I need dessert but don’t want to bake” moments. Two slices later, and I’m convinced it’s the best chocolate cake for the price.
Step-by-step instructions for america's Test Kitchen chocolate cake
Master this foolproof method for consistently moist layers and perfect rise every time.
👨🍳 Step 1: Prepare the Cake Pans and Preheat
Preheat your oven to 350°F with racks positioned in the upper and lower thirds. Generously grease two 8-inch round cake pans with the 1 cup unsalted butter, then line the bottoms with parchment rounds. Dust the sides with 1 tablespoon all-purpose flour, tapping out any excess. This prevents sticking while ensuring clean release.
I use a pastry brush to distribute the butter evenly—don't skip this step. The flour creates a barrier between the cake and pan, but too much can make the sides tough. Brush the butter in one direction, then dust with flour in the opposite direction for complete coverage.
🍳 Step 2: Cream Butter and Sugars for Maximum Moisture
In a stand mixer fitted with the paddle attachment, beat the 1 cup cold cubed butter on medium speed until creamy but not melted (2-3 minutes). Add the 2.25 cups granulated sugar and 0.25 cup packed dark brown sugar, then beat on high speed for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume.
This step incorporates air into the batter, which creates the cake's structure and moisture. The cold butter creates tiny pockets that hold air, while the brown sugar adds moisture and depth. Stop when the mixture is pale and ribbon-like—overmixing develops gluten and makes the cake dense.
👨🍳 Step 3: Add Eggs and Dry Ingredients in Stages
Add the 2 room-temperature whole eggs, one at a time, mixing on low speed after each addition until fully incorporated. Scrape down the sides of the bowl as needed. In a separate bowl, whisk together the 2 cups sifted all-purpose flour, 1 tablespoon baking powder, 0.5 teaspoon salt, 0.75 cup unsweetened cocoa powder, 1 teaspoon espresso powder, and 2 teaspoons vanilla extract.
With the mixer on low speed, gradually add the dry ingredients to the butter-sugar mixture in 3 additions, mixing just until combined after each. This prevents overmixing which develops gluten. The espresso powder enhances the chocolate flavor without adding bitterness—don't skip it.
🥘 Step 4: Combine Wet Ingredients and Fold Gently
In a measuring cup, whisk together the 0.75 cup milk, 0.25 cup buttermilk, and 0.25 cup vegetable oil. With the mixer on low speed, gradually pour the wet ingredients into the batter, mixing just until the flour is moistened. Avoid overmixing—you should still see small flour streaks.
This step ensures even distribution of moisture without developing gluten. The buttermilk adds tang and tenderness, while the oil creates a tender crumb. The batter should be thick but pourable. If it's too thick, add 1-2 tablespoons milk to reach the proper consistency.
⏰ Step 5: Bake for Perfectly Moist Layers
Divide the batter evenly between the prepared pans. Bake for 25-30 minutes, rotating the pans halfway through, until a toothpick inserted in the center comes out with moist crumbs but no wet batter. The edges should be set but the tops should still look slightly underbaked.
This baking time ensures moist layers without a dense center. The cake should spring back when gently pressed in the center. If the tops brown too quickly, loosely tent with foil. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before frosting.
Pro Tips For Making America'S Test Kitchen Chocolate Cake
- STOP WHISKING TOO SOON: The butter-sugar mix needs 3-4 minutes on medium-high to get pale yellow and ribbony—not just creamy. I used to cut it short, and the cake turned out dense. The recipe relies on that airy emulsion, so resist the urge to rush.
- SIFT THE COCOA: No, I’m not kidding. The ATK recipe uses Dutch-process cocoa, and sifting it removes clumps that can create dry pockets. Do this before mixing with the dry ingredients—your cake’s texture will thank you.
- DON’T OVERMIX THE BATTER: Once you fold in the flour mixture, stop after 10-12 strokes. Overmixing develops gluten, and that’s how you end up with a cake that’s more cakey than fudgy. The recipe’s magic is in the restraint.
- USE ROOM-TEMP EGG WHITES: Cold whites whip up with more volume, but they also deflate faster. If your kitchen’s chilly, let the whites sit out for 30 minutes before whipping. The difference in rise is noticeable—especially in a dense chocolate cake.
Troubleshooting this recipe
Cake Stuck in Pans
If your cake layers refuse to release from the pans, you likely missed the flour-dusting step or didn’t grease properly. First, chill the pans in the fridge for 10 minutes to firm up the cake. Then, run a thin, flexible knife or offset spatula around the edges to loosen.
For stubborn spots, place a damp paper towel over the cake and flip the pan onto a plate—gravity helps release it. Always use European-style butter for better greasing results. 🧈
Dry or Crumbly Texture
Overbaking is the usual culprit, but dryness can also come from overmixing the batter or using too much flour. To fix it, reduce baking time by 2-3 minutes—the cake should spring back when pressed.
For extra moisture, brush warm layers with simple syrup (½ cup sugar + ¼ cup water, heated until dissolved) before frosting. If the crumb is too coarse, sift your flour again and ensure your baking powder is fresh—old leavening loses potency.
Soggy Bottoms
This happens when steam escapes too quickly or the oven isn’t properly preheated. First, always use parchment paper lined with a silicone mat or extra parchment circles. Second, preheat your oven for at least 20 minutes—use an oven thermometer to confirm it’s at 350°F.
If the bottoms are already soggy, place the cake on a wire rack over a baking sheet and bake at 300°F for 5-10 minutes to dry them out slightly.
Cracked or Sunken Top
Cracks usually mean the batter was too wet or the oven temperature fluctuated. To prevent this, ensure your buttermilk and milk are room temperature—cold liquids can cause uneven rising. For a sunken top, the cake likely cooled too quickly.
Next time, let the cakes cool in the pans for 15 minutes before transferring to a rack. If it’s already sunken, frost immediately with a stiff buttercream—the weight helps hold the structure.
Bitter Aftertaste
Bitter chocolate flavor often comes from overmixing or using low-quality cocoa powder. Stick to Dutch-processed cocoa like Valrhona or Guittard, and avoid overmixing the batter. If the cake tastes bitter, try adding 1 teaspoon vanilla extract to the frosting to balance the flavor.
For extra depth, add ½ teaspoon instant espresso powder to the frosting as well—it enhances sweetness without bitterness.
Uneven Rise
Uneven baking usually means your oven has hot spots or the cakes weren’t rotated halfway through. Always position racks in the upper and lower thirds of the oven and swap pans at the 15-minute mark.
If your oven runs hot, reduce the temperature by 10°F and add 5 minutes to the baking time. For a convection oven, reduce the temperature by 25°F and check for doneness 2-3 minutes early.

Frequently asked questions
Why does America's Test Kitchen use reverse creaming for this chocolate cake?
The reverse creaming method (mixing dry ingredients into butter first) creates a more tender crumb by preventing gluten development. This technique also ensures even moisture distribution, resulting in layers that stay moist for days. The cold butter incorporates air more effectively than room-temperature fat, giving the cake its signature lightness.
Can I make this cake in a 9-inch pan instead of 8-inch?
Yes, but reduce the batter by about 20% to prevent overflow. Bake for 20-25 minutes instead of 25-30, checking for doneness 2 minutes early. The cake will be slightly thicker but still moist. For best results, use a water bath (bain-marie) to ensure even cooking.
What's the best frosting to pair with this cake?
America's Test Kitchen recommends their chocolate buttercream (made with cocoa powder and espresso powder) for maximum flavor harmony. For a lighter option, try ganache or whipped cream with a dusting of cocoa powder. Avoid overly sweet frostings—the cake's rich chocolate flavor stands on its own.
How do I store leftovers to keep them fresh?
Wrap frosted layers tightly in plastic wrap and store at room temperature for up to 3 days. For longer storage, refrigerate for 5 days or freeze unfrosted layers for 3 months. Thaw at room temperature before frosting. Never refrigerate frosted cakes longer than 24 hours—condensation makes frosting soggy.
Can I substitute Dutch-processed cocoa powder?
Use natural cocoa powder only if you reduce the baking powder by 0.25 teaspoons to prevent over-leavening. The cake will be slightly more acidic but still delicious. For best results, stick with Dutch-processed cocoa—it dissolves smoothly and gives that signature velvety texture. The espresso powder can be omitted if using natural cocoa, but the flavor won't be as deep.
