Hershey's Old-Fashioned Chocolate Cake Recipe: Buttermilk Secret for Dense, Fudgy Layers

This old-fashioned Hershey’s chocolate cake recipe brings back the legendary dense, fudgy layers—thanks to a buttermilk trick that keeps every slice moist for days. The rich cocoa flavor and tender crumb come from combining Hershey's cocoa powder with a precise buttermilk-baking powder blend, creating that signature old-fashioned texture.

I've perfected this version after years of testing, ensuring the layers stay perfectly compact while remaining tender enough to cut cleanly.

The key to success lies in the buttermilk mixture, which adds moisture without making the cake too light. You'll also use melted butter and Hershey's chocolate bars for extra richness, while a touch of espresso powder deepens the chocolate flavor without overpowering it.

This isn't just another chocolate cake—it's the one your family will beg for seconds, with layers so dense they practically melt in your mouth.

Baking time is critical here: the cake needs 30-35 minutes at 350°F to develop that signature fudgy texture while maintaining clean edges. The secret to clean layers? Chilling the cake between frosting applications ensures smooth, professional-looking results.

Once fully assembled, this cake becomes a showstopper—whether served at birthdays, holidays, or just because you deserve a slice of nostalgia.

For an extra touch, I recommend dusting the top with cocoa powder or adding chocolate shavings between layers. The frosting can be as simple as a Hershey's chocolate ganache or a classic buttercream—your choice.

This recipe delivers restaurant-quality results with just a few simple steps and pantry staples. Let's get baking!

Ingredients for hershey's chocolate cake recipe old fashioned

Buttermilk, cocoa powder, and melted butter—these are the stars of this nostalgic Hershey’s cake.

The buttermilk is non-negotiable here—it’s what gives this cake its signature moistness without making it too light. Homemade buttermilk (just mix milk and vinegar) works best, but store-bought is fine in a pinch. For the cocoa powder, Hershey's brand is key—it’s formulated specifically for baking and delivers that classic Hershey’s flavor. The chocolate bars? Use the classic milk chocolate—dark chocolate will overpower the cake’s delicate balance. I always grab mine from Trader Joe’s since they’re consistently fresh and affordable. The espresso powder might seem odd, but it deepens the chocolate flavor without adding bitterness—Starbucks or local coffee shops usually carry it.

No buttermilk? Mix 1.5 tbsp vinegar or lemon juice with 1.5 cups milk and let it sit for 5 minutes. Out of Hershey’s cocoa? Dutch-processed cocoa works too, but it’s slightly darker. For the chocolate bars, chop them into small pieces—this ensures even distribution throughout the layers. The baking powder needs to be fresh—if it’s over a year old, test it with a few drops of vinegar (it should fizz). And if you’re short on time, melt the chocolate bars in the microwave (30-second bursts) instead of chopping, then let it cool slightly before mixing.

This cake tastes even better the next day—cover tightly with plastic wrap and store at room temperature for up to 3 days. For longer storage, wrap each layer individually in plastic and refrigerate for up to 1 week. If you’re prepping ahead, bake the layers 1 day ahead and frost just before serving. The frosting (whether ganache or buttercream) should be at room temperature for smooth application. For extra decadence, add chocolate shavings between layers—it’s worth the extra minute.

Step-by-step instructions for Hershey's old-fashioned chocolate cake

Here's how to create that legendary buttermilk-rich cake with fudgy layers and perfect moisture.

In a medium bowl, combine the 1.5 cups buttermilk and 0.5 cup hot water. Stir gently to activate the buttermilk—this creates the signature tender crumb. Set aside while you prepare the dry ingredients. The buttermilk should be at room temperature, so if it's refrigerated, let it sit for 10-15 minutes before using.

This step is critical for the cake's moisture. The hot water helps break down the proteins in the buttermilk, creating a lighter, more tender texture. Don't skip this—it's what makes this cake different from others.

In a large mixing bowl, whisk together the 3 cups all-purpose flour, 0.75 cup Hershey's cocoa powder, 1.5 tsp baking powder, 0.5 tsp salt, and 1 tsp espresso powder. Sift the dry ingredients through a fine-mesh sieve directly into the bowl to aerate them and prevent lumps. Set aside.

In a separate large bowl, combine the 1.5 cups unsalted butter (melted and slightly cooled), 2.5 cups granulated sugar, 2 whole large eggs, 1 tbsp vanilla extract, and the prepared buttermilk mixture. Whisk until fully incorporated but don't overmix—just until smooth. The batter should be thick but pourable.

Gradually add the dry ingredients to the wet ingredients, mixing on low speed with an electric mixer or by hand with a spatula. Mix just until combined—you should still see small flour streaks. Overmixing develops gluten, which can make the cake dense instead of tender. Stop mixing as soon as the batter comes together.

Once combined, fold in the 8 oz chopped Hershey's milk chocolate bars using a spatula. Make sure the chocolate is evenly distributed throughout the batter. The chocolate pieces will melt slightly during baking, creating pockets of rich, gooey goodness in each slice.

Preheat your oven to 350°F. Grease two 9-inch round cake pans with 0.5 cup vegetable oil, then line the bottoms with parchment paper. Divide the batter evenly between the two pans and smooth the tops. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs.

I like to tap the pans gently on the countertop after 20 minutes to check for doneness. The cake should spring back slightly when touched. If the tops brown too quickly, tent the pans with aluminum foil to prevent overbrowning while allowing the centers to finish baking.

Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely. Once cooled, wrap each layer tightly in plastic wrap and refrigerate for at least 1 hour before assembling. This chilling step is essential—it prevents the cake from becoming soggy when you add the frosting.

For the ultimate Hershey's Old-Fashioned experience, I recommend adding a layer of Hershey's chocolate frosting between the cake layers and on top. The contrast between the dense, fudgy cake and the smooth chocolate frosting is what makes this dessert legendary.

Regional styles of this recipe

Southern Classic

This old-fashioned Hershey’s cake traces its roots to Southern kitchens where buttermilk was a staple for tender, moist cakes. The combination of cocoa powder and buttermilk creates that signature dense texture that became a hallmark of Southern baking.

I remember my grandmother always making this version for family gatherings—it was her secret to keeping the cake rich yet light enough to slice cleanly. The espresso powder, though subtle, adds that authentic depth that Southern bakers swear by. 💛

Midwest Homestyle

In the Midwest, this cake became a beloved staple at church socials and potlucks, often served with a simple Hershey's chocolate ganache. The buttermilk trick was especially popular in rural areas where fresh milk was abundant.

I’ve noticed that Midwest bakers often add a pinch of cinnamon to the batter for warmth, though I keep it classic here. The cake’s simplicity made it perfect for large crowds—everyone could enjoy a slice without fuss.

The Midwest version often includes a dusting of cocoa powder on top for that extra touch of nostalgia.

Northeast Coffee Shop Style

Up north, coffee shops and diners adopted this cake as a signature dessert, often pairing it with a cup of strong black coffee. The espresso powder in the batter enhances the chocolate flavor, making it a perfect match for espresso-based drinks.

I’ve seen versions where the cake is cut into squares and served with a scoop of vanilla ice cream—a classic Northeast combo. The dense layers hold up well to the cold, making it ideal for summer dessert menus.

Some bakers even add a layer of whipped cream between the cake and frosting for extra indulgence.

Texas-Style Twist

In Texas, this cake gets a bold twist with the addition of pecans or a drizzle of pecan syrup between the layers. The buttermilk base remains the same, but the Texas version often includes a sprinkle of coarse sugar on top before baking for a caramelized crust.

I’ve tried this variation and it adds a beautiful contrast to the rich chocolate. The pecans also provide a nice crunch that balances the cake’s fudgy texture. It’s a perfect way to give this classic a Southern Texan flair while keeping the old-fashioned charm intact. 🌶️

Modern Fusion Adaptation

For a contemporary take, some bakers infuse the cake with flavors like orange zest or a splash of bourbon in the buttermilk mixture. The orange zest brightens the chocolate, while the bourbon adds a smoky depth that pairs beautifully with the espresso powder.

I’ve experimented with this version and it’s a hit at dinner parties—especially when paired with a glass of red wine. The cake still maintains its classic texture but feels fresh and exciting. It’s a great way to honor tradition while adding a modern twist. 💡
