This America's Test Kitchen old-fashioned chocolate cake delivers moist, tender layers and deep chocolate flavor without a single overmixed crumb. The secret lies in precise mixing techniques and strategic ingredient ratios that create a cake with a rich, fudgy texture—no dryness or dense heaviness in sight.
The recipe relies on two key steps: first, combining dry ingredients with melted butter for even distribution, then folding in just enough egg mixture to create structure without overdevelopment. This method ensures perfectly moist crumbs that stay tender for days, not hours.
The cake's signature flavor comes from Dutch-process cocoa and a touch of espresso powder, which deepens the chocolate notes without bitterness.
What sets this apart is the foolproof baking technique: a single layer baked at 350°F for 30-35 minutes, resulting in a cake with a slightly domed top and edges that pull away cleanly from the pan.
The texture is uniform from edge to center, with no risk of underbaking or overbrowning. No special equipment is needed—just a standard 9-inch round pan and a reliable oven thermometer for accuracy.
Serve warm with vanilla ice cream or whipped cream for the classic presentation, or enjoy it at room temperature for a rich, satisfying dessert that tastes like a bakery favorite.
The recipe scales perfectly for gatherings, and leftovers keep their moisture for up to 5 days when stored properly. Here's how to achieve this restaurant-quality result at home.
Ingredients for america's test kitchen old fashioned chocolate cake
Precision-measured ingredients for a cake with restaurant-quality moisture and depth.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ¼ cups | Sifted for even distribution |
| Dutch-Process Cocoa Powder 🍫 | ¾ cup | High-quality, unsweetened |
| Granulated Sugar 🍚 | 2 cups | Light brown preferred |
| Unsalted Butter 🧈 | 1 cup | Melted, cooled slightly |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Instant Espresso Powder ☕ | 1 tbsp | For deep chocolate flavor |
| Baking Powder 🧂 | 1 ½ tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌸 | 1 tbsp | Pure, high-quality |
| Buttermilk 🥛 | ½ cup | Homemade or store-bought |
| Vegetable Oil 🫒 | ¼ cup | Light, neutral flavor |
The cocoa powder is non-negotiable—Dutch-process delivers that signature rich flavor without bitterness. Hershey's Special Dark or Valrhona Cocoa are top-tier choices, but any high-quality unsweetened cocoa will work. For the sugar, light brown adds subtle moisture, though granulated is fine if that's what you have. The butter must be melted and cooled slightly to prevent overmixing when combined with dry ingredients. Room-temperature eggs incorporate more smoothly, so take them out 30 minutes before baking. Espresso powder might seem unusual, but it deepens the chocolate notes without adding bitterness—Starbucks or Folgers instant works perfectly.
No buttermilk? Mix 0.5 cup milk with 0.5 tsp vinegar or lemon juice and let sit 5 minutes. Vegetable oil can be swapped for melted butter at the same quantity, though it yields slightly denser crumbs. For a gluten-free adaptation, use a 1:1 flour blend like Bob's Red Mill. The baking powder must be aluminum-free to prevent metallic aftertaste—Clabber Girl is a reliable brand. If your pan isn't nonstick, grease it thoroughly with vegetable shortening or line with parchment paper for easy release. The vanilla extract should be pure, not imitation—Nielsen-Massey is a trusted name in professional kitchens.
Store the cake in an airtight container at room temperature for up to 5 days, or refrigerate for 7 days if you prefer cooler slices. For longer storage, freeze individual layers wrapped in plastic for up to 3 months. To serve, bring to room temperature for 30 minutes—this restores moisture and enhances flavor. The cake reheats beautifully in a 350°F oven for 10 minutes if you prefer it warm, though it's equally delicious at room temperature. Portion into slices before storing to maintain clean cuts.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by the creaming method here—just butter, sugar, and eggs beaten until light and fluffy. No fancy techniques, no stress. The Dutch-process cocoa powder cuts through the richness like a whisper, so you don’t end up with a brick.
- Decadent Without Guilt: That first bite? Rich, fudgy, and just dense enough to feel special—but not so heavy it lingers. The butter-to-sugar ratio is spot-on, and the eggs add structure without drying it out. Honestly, it’s the kind of chocolate cake that makes you forget it’s “old-fashioned.”
- Weeknight Hero: Slice it warm for breakfast with a scoop of vanilla ice cream, or pack layers for lunch the next day. It travels well, reheats beautifully, and even my picky teen devours it. (Yes, even when I forget to add sprinkles.)
- Budget-Friendly Luxury: You’re using pantry staples—no specialty ingredients, no pricey shortcuts. A single batch feeds six, and leftovers? They disappear faster than I can say “second cup of coffee.” Plus, the cocoa powder stretches further than store-bought mixes.
Step-by-step instructions for america's Test Kitchen old fashioned chocolate cake
Master this classic technique for layers that stay moist and rich without overmixing.
Prepare the Dry Ingredients for Even Distribution
In a medium bowl, sift together the 2.25 cups all-purpose flour, 0.75 cup Dutch-process cocoa powder, 1.5 teaspoons baking powder, and 0.5 teaspoon salt. Whisk gently to combine, breaking up any cocoa lumps. This ensures your cake batter will be light and aerated, preventing dense layers. I like to use a fine-mesh sieve for the cocoa powder to eliminate any grit that can affect texture.
Set this mixture aside while you prepare the wet ingredients. The reason for sifting now is to incorporate air into the dry ingredients, which helps create a tender crumb. Don't skip this step—it makes all the difference in achieving that signature moist texture America's Test Kitchen is known for.
Cream Butter and Sugar for Maximum Aeration
In a separate large bowl, combine the 1 cup melted unsalted butter (cooled slightly) with the 2 cups granulated sugar. Using an electric mixer on medium-high speed, beat for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume. You'll notice the color lighten slightly as air is incorporated—a visual cue that the butter and sugar are properly emulsified.
This creaming process is critical for creating the cake's tender crumb. The butter should be cool enough to hold its shape when pressed but still fluid enough to mix smoothly. If it's too cold, the butter will seize up; if too warm, it may separate. Aim for a temperature where it's just slightly soft to the touch.
Incorporate Eggs and Espresso Powder for Depth of Flavor
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tablespoon instant espresso powder and 1 tablespoon vanilla extract. The espresso powder enhances the chocolate flavor without adding bitterness, while the vanilla adds complexity. Mix until just combined—overmixing at this stage can develop gluten and make the cake tough.
Here's where precision matters: beat for only 30 seconds after adding the eggs. You want to incorporate them completely without overworking the batter. The mixture should be smooth but still slightly thick. This step ensures your cake will have that signature moist texture without being dense.
Alternate Dry and Wet Ingredients for Perfect Texture
With the mixer on low speed, add one-third of the dry ingredients to the wet mixture. Mix just until combined, then alternate adding the remaining dry ingredients in two more additions with the 0.5 cup buttermilk and 0.25 cup vegetable oil, beginning and ending with the dry ingredients. This alternating method creates a light, airy batter without overdeveloping the gluten.
Scrape down the sides of the bowl as needed to ensure even mixing. The batter should be thick but pourable. If it looks too stiff, don't panic—this is normal for a rich chocolate cake. The key is to mix just until the ingredients are combined, no more. Overmixing is the enemy of a tender crumb.
Bake for Evenly Moist Layers
Preheat your oven to 350°F and grease two 9-inch round cake pans with vegetable oil, then line the bottoms with parchment paper. Divide the batter evenly between the pans. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Rotate the pans halfway through baking for even browning.
The cake should spring back slightly when pressed in the center. If the tops brown too quickly, tent loosely with foil. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. This gradual cooling prevents cracking and ensures the layers stay moist. For best results, serve the cake at room temperature.
Pro Tips For Making America'S Test Kitchen Old Fashioned Chocolate Cake
- Whisk Eggs Until Ribbon Stage: The recipe calls for beating eggs until pale and thick—don’t just give it a few pulses. Use a stand mixer with the whisk attachment and go until the ribbon test passes (when you lift the whisk, the batter trails slowly). I learned this the hard way after a cake turned dense and flat; those eggs need serious air.
- Sift That Cocoa: Dutch-process cocoa powder clumps like a stubborn child if you don’t sift it first. Even if the recipe doesn’t explicitly say to, take the extra 30 seconds—especially if your cocoa is old or has been sitting in a humid kitchen. Trust me, your cake’s texture will thank you.
- Don’t Overmix the Batter: Once you fold in the dry ingredients, stop as soon as they’re just combined. Overmixing develops gluten and turns your cake into a dense brick. The recipe’s gentle folding method is intentional—resist the urge to stir like you’re making pancakes.
- Use Room-Temp Butter: Cold butter creates pockets of air in the batter, but if it’s straight from the fridge, it won’t emulsify properly. Let it sit out for 30–45 minutes until it’s soft enough to press with your finger but still holds its shape. I used to skip this, and my cakes always had a weird, uneven crumb.
Dietary considerations for this recipe
Gluten-Free Adaptation
Replace the 2.25 cups all-purpose flour with a 1:1 gluten-free flour blend like Bob's Red Mill or King Arthur Measure for Measure. These blends contain xanthan gum, which mimics gluten's structure for proper texture.
For best results, weigh the flour using a kitchen scale—9.5 ounces total—to ensure accuracy. The cake will still be moist but may have a slightly denser crumb. 🌾
Dairy-Free Substitutions
Swap the 1 cup melted butter for vegetable shortening or coconut oil (refined, for neutral flavor) to maintain the cake's tenderness. Replace the 0.5 cup buttermilk with unsweetened almond milk mixed with 0.5 teaspoon apple cider vinegar—let it sit for 5 minutes to curdle.
The espresso powder and cocoa still deliver rich flavor without dairy. For extra richness, use dairy-free chocolate chips in the frosting.
Lower-Sugar Options
Reduce the 2 cups granulated sugar to 1.5 cups and replace the remaining 0.5 cup with monk fruit sweetener or erythritol for a 1:1 substitution. The cake will still taste sweet but with fewer calories.
For added moisture, increase the vegetable oil to 0.35 cups. Test with a toothpick early—lower-sugar cakes may need 2-3 minutes less bake time to avoid dryness.
Nut-Free Considerations
If avoiding nuts entirely, skip the vegetable oil (which may be processed in nut facilities) and use avocado oil instead—it's neutral and nut-free. For buttermilk, opt for oat milk mixed with vinegar, as many brands process almond milk in nut-free facilities.
Double-check labels on all ingredients, especially cocoa powder and baking powder, for cross-contamination warnings.
Egg-Free Adaptation
Replace the 2 eggs with 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let sit 5 minutes to gel). Add 1 teaspoon apple cider vinegar to the batter to enhance rise. The cake may be slightly denser but will retain moisture.
For extra structure, increase the baking powder to 2 teaspoons. Bake for 38-42 minutes—egg-free cakes often need extra time to set.
Storage Adjustments
Gluten-free and egg-free versions dry out faster. Store in an airtight container with a slice of bread or apple to retain moisture. Refrigerate for up to 4 days or freeze layers for 2 months.
To reheat, wrap slices in a damp paper towel and microwave for 10-15 seconds. These adaptations keep the cake's signature richness while accommodating dietary needs. ✨

Frequently asked questions
Why does this recipe use melted butter instead of creamed butter?
Melted butter creates a more tender crumb by distributing fat evenly throughout the batter. When combined with dry ingredients first, it prevents overdevelopment of gluten, which would make the cake tough. The slight cooling before mixing ensures the butter doesn't melt in the oven too quickly, helping maintain moisture during baking. This method is America's Test Kitchen's signature approach for their signature cake texture!
Can I make this cake in a single 9-inch pan instead of two?
Yes, but expect a thicker, denser slice. Divide the batter into the single pan and bake for 40-45 minutes at 350°F, checking with a toothpick. For a classic layered look, stick with two pans—they create the signature tall, elegant slices. If using one pan, reduce baking powder by 0.5 teaspoon to prevent excessive rise.
How do I prevent the cake from cracking on top?
Cracking usually happens from rapid cooling or overbaking. Let the cake cool in the pan for 10 minutes before transferring to a rack, and never open the oven door in the last 15 minutes of baking. If cracks appear, brush them with simple syrup (equal parts sugar and water, heated until dissolved) before frosting to disguise them. For extra insurance, tent the pans loosely with foil if the top browns too quickly.
What's the best way to store leftovers?
Wrap individual layers tightly in plastic wrap, then place in an airtight container at room temperature for up to 5 days. For longer storage, freeze layers for 3 months. Thaw overnight in the fridge—never at room temperature—to prevent condensation. To revive stale slices, wrap in a damp paper towel and microwave for 10-15 seconds before serving.
Can I substitute coffee for the espresso powder?
Not directly—coffee's liquid volume would alter the batter's consistency. For the same flavor boost, use 1 tablespoon instant espresso powder (like Starbucks or Folgers). If you must use brewed coffee, reduce other liquids in the recipe by 2 tablespoons first. The powder dissolves completely and enhances chocolate flavor without adding moisture that could make the cake gummy.
