Betty Crocker Chocolate Devil Cake Recipe: Fudgy Layers and Secret Buttermilk Moisture

Betty Crocker's Chocolate Devil Cake delivers the perfect balance of fudgy layers and moist crumb that makes every slice irresistible. The secret lies in buttermilk's tenderizing magic and precise layering—no dry cake here.

I've baked this recipe countless times, and it never disappoints, whether you're celebrating a birthday or just craving comfort. This isn't just dessert; it's an experience that starts with the first aroma wafting from your oven.

What sets this recipe apart is the foolproof technique that ensures rich, chocolatey layers without cracking or drying out. The cake batter relies on buttermilk for moisture while cocoa powder delivers deep, velvety flavor.

You'll bake it in two layers, then fill with a velvety chocolate frosting that melts into every bite. The result? A dessert that looks impressive but comes together with straightforward steps—ideal for both beginners and seasoned bakers.

By the time you're done, you'll have a moist, decadent cake with layers so tender they practically dissolve on your tongue. The frosting adds the perfect contrast, creating a texture that's rich yet light.

This cake is designed to impress—whether you're serving it at a gathering or enjoying a quiet slice with a cup of coffee. The secret to its success? Precision in measurements and patience during cooling.

Once baked and cooled, the cake keeps beautifully for up to three days, making it perfect for meal prep or special occasions. The frosting can be adjusted for dietary needs, and the layers hold up well when sliced.

Every bite delivers that classic Chocolate Devil Cake flavor you remember, but with a modern twist that feels fresh and inviting. Let's get started on creating your perfect slice.

Ingredients for betty crocker chocolate devil cake

Rich cocoa, velvety butter, and buttermilk’s secret moisture—these are your cake’s superstars.

The cocoa powder is non-negotiable here. Natural cocoa (like Hershey’s Special Dark) gives that deep, velvety flavor without bitterness. Ghirardelli or Valrhona are splurge options, but the store brand works too—just check the label for ‘natural’ (not Dutch-processed). For the buttermilk, if you’re in a pinch, mix 1 tbsp vinegar or lemon juice with 1 cup milk and let it sit for 5 minutes. The butter? Use full-fat, never margarine—this is where the fudgy magic happens. And the eggs? Room temperature, please—they’ll blend smoother and give you that tender crumb.

No buttermilk? Plain yogurt works at a 1:1 ratio, but the cake might be slightly denser. Running out of cocoa powder? Melted dark chocolate at half the amount gets you close, but texture might change. The frosting can be adjusted too—add 1 tsp vanilla extract if you’re feeling fancy, or 1 tbsp cocoa powder for extra richness. For the chocolate chips in the frosting, Ghirardelli or Nestlé Toll House are the gold standard, but any semi-sweet will do. And if you’re watching sugar, reduce the powdered sugar by 1/4 cup—it’s still delicious.

This cake keeps beautifully for 3 days at room temperature, wrapped tightly in plastic. For longer storage, freeze the layers (unfrosted) for up to 3 monthsStore it in the fridge and bring to room temp before spreading. Pro tip: Assemble the cake the night before—it tastes even better after sitting overnight, with all the flavors settling in.

Step-by-step instructions for betty crocker chocolate devil cake

Here's how to create layers so moist they'll make you swoon every time.

Preheat your oven to 350°F and grease two 9-inch round cake pans with vegetable oil, then line the bottoms with parchment paper. In a medium saucepan, combine the 0.5 cup hot water and 0.75 cup cocoa powder, whisking until the cocoa is completely dissolved and the mixture is smooth. Let it cool for 5 minutes—this ensures the cocoa doesn't cook your eggs when you mix them in later.

In a large mixing bowl, cream together the 1 cup unsalted butter and 2 cups granulated sugar using an electric mixer on medium-high speed for 3-4 minutes until light and fluffy. This step is crucial for aerating the batter, which gives those signature tender layers. Add the 2 whole large eggs, one at a time, mixing well after each addition. Scrape down the sides of the bowl to ensure everything is fully incorporated.

In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 teaspoons baking powder, and 0.5 teaspoon salt. Sift the mixture directly into the wet ingredients to avoid lumps—this creates a lighter texture. Add the 1 cup buttermilk and mix on low speed until just combined. Be careful not to overmix; stop as soon as the ingredients are evenly distributed. Overmixing develops gluten, which can make the cake dense.

Pour the cooled cocoa mixture into the batter and mix on low speed for 30 seconds until fully incorporated. Finally, add the 2 teaspoons vanilla extract and 0.5 cup vegetable oil, mixing just until combined. The batter should be thick but pourable. Divide the batter evenly between the prepared cake pans, spreading it out to create level tops. This ensures even baking and perfectly uniform layers.

Bake the cakes in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden brown, and the tops should spring back slightly when touched. Here's the thing—don't open the oven door early to check on the cakes. The sudden temperature change can cause them to sink in the middle. If you're unsure, rely on the toothpick test rather than visual cues.

Once baked, remove the cakes from the oven and let them cool in the pans for 10 minutes. Then, run a thin knife around the edges to loosen them from the pans before transferring to a wire rack to cool completely. This cooling step is essential for preventing the cakes from becoming gummy when you frost them later.

In a medium bowl, combine the 3 cups powdered sugar, 1 cup heavy cream, and 0.5 cup unsweetened chocolate. Mix until smooth, then gradually add more powdered sugar if the frosting is too thin, or more heavy cream if it's too thick. You want a consistency that's spreadable but still holds its shape—like a thick pudding. This frosting is the star of the show, so take your time to get it just right.

Once the cakes are completely cool, spread a thin layer of frosting on the bottom cake to help it stick. Then, place the second cake on top and spread the remaining frosting evenly over the top and sides of the cake. Use a spatula to create smooth sides and a slightly domed top. Chill the cake in the refrigerator for 30 minutes before slicing. This helps the frosting set and makes it easier to cut clean slices.

Essential equipment for this dish

Mixing Essentials

You’ll need a stand mixer or hand mixer with a beater attachment for creaming butter and sugar—this ensures the perfect light, fluffy texture. I recommend a KitchenAid Artisan Series for its power and durability, but a budget-friendly Hamilton Beach works too.

For measuring, a digital kitchen scale (like the OXO Good Grips) is ideal for precise cocoa and flour measurements, but standard measuring cups work in a pinch.

Baking Tools

Two 9-inch round cake pans with removable bottoms are a must—they help release the cake cleanly. I use Wilton Perfect Results pans because they’re non-stick and durable. Line the bottoms with parchment paper to prevent sticking, and grease them with vegetable oil for extra insurance.

A toothpick is essential for testing doneness—insert it into the center, and it should come out clean.

Frosting Gear

For the frosting, a medium mixing bowl and spatula are all you need, but a piping bag with a star tip (like the Wilton 1M) elevates presentation. If you’re feeling fancy, a cake turntable (such as the Ateco 10-inch) makes frosting smoother and more even.

For chilling, a large cooling rack keeps the cake elevated while the frosting sets.

Optional Upgrades

A cake leveler (like the OXO Good Grips) trims uneven layers for a professional finish. For extra moisture, I sometimes use a thermometer to monitor the oven’s temperature—350°F is critical here.

If you’re making this often, a cake stand (such as the West Elm Acorn) adds a polished touch to your presentation. 💫
