Savor the Richness of Old Fashioned Chocolate Buttermilk Cake

Treat yourself and loved ones to the warm, comforting flavors of Old Fashioned Chocolate Buttermilk Cake. This cake combines deep chocolate notes, a tender crumb, and a frosting that brings it all together. Whether you serve it for a birthday, a cozy afternoon, or a holiday gathering, it delivers that timeless cake experience you crave.

You’ll find simple ingredients, straightforward steps, and helpful tips to make this cake a success. Ready to bake? Let’s get started with the classic recipe that feels like home.

Why This Old Fashioned Chocolate Buttermilk Cake Stands Out

Baking this Old Fashioned Chocolate Buttermilk Cake brings a lovely balance of moistness and flavor. Because we use buttermilk, your cake stays tender and rich rather than dry. Meanwhile, the adjustment of hot cocoa and water gives depth without heaviness. This is truly a cake you’ll return to again and again.

Also, the frosting is warm and flows into every crack in the cake, adding both sweetness and a bit of softness. And with a modest ingredient list, it’s accessible to every level of baker.

Below, you’ll find pro tips, ingredient notes, and a clear, step-by-step method to make this cake shine.

Pro Tips for a Perfect Old Fashioned Chocolate Buttermilk Cake

  1. Bring ingredients to room temperature before starting. This helps them combine more smoothly and evenly.
  2. Do not overmix once you combine wet and dry ingredients. Overmixing can develop gluten and make the cake dense.
  3. Use a thermometer, if possible, to check your oven’s accuracy. Oven variances can affect baking time.
  4. Tilt and rotate the pan halfway through baking for even browning, but be gentle to avoid collapse.
  5. Pour frosting while cake is warm, so it seeps in nicely and forms a glossy top.
  6. Let it cool completely before slicing. Warm slices may fall apart.

Ingredients for the Old Fashioned Chocolate Buttermilk Cake

For the Cake

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup (2 sticks) butter
  • 1 cup water
  • ⅓ cup unsweetened cocoa powder
  • ½ cup buttermilk
  • 2 eggs
  • 1 teaspoon vanilla

For the Frosting

  • ¼ cup (half of a stick) butter
  • 4 Tablespoons buttermilk
  • 3 Tablespoons unsweetened cocoa powder
  • 2 ¼ cups powdered sugar
  • ½ teaspoon vanilla

Directions: How to Bake Old Fashioned Chocolate Buttermilk Cake

For the Cake

  1. Preheat your oven to 350°F (175°C). Grease a 9 × 13-inch glass baking dish.
  2. In a stand mixer bowl, whisk together the flour, sugar, baking powder, and salt until well blended.
  3. In a medium saucepan, combine the butter, water, and cocoa powder. Heat over medium until it reaches a boil, stirring constantly so it doesn’t burn.
  4. With the mixer running on low, pour the hot chocolate mixture into the dry ingredients. Beat until smooth and fully incorporated.
  5. Add the buttermilk, then the eggs and vanilla. Beat again until the batter is silky and even.
  6. Scrape the batter into the prepared pan, smoothing it to the edges.
  7. Bake for 25 to 30 minutes, or until a cake tester inserted in the center comes out clean or with just a few moist crumbs.
  8. Remove from oven and set aside to begin frosting right away.

For the Frosting

  1. Use the same saucepan (or another clean one). Bring butter, cocoa powder, and buttermilk to a gentle boil.
  2. Remove from heat, then beat in the powdered sugar gradually until you reach a smooth, spreadable frosting.
  3. Stir in the vanilla.
  4. Immediately pour the warm frosting over the hot cake. Tilt the dish so the frosting covers evenly.
  5. Let the cake cool fully before cutting into slices.

Serving and Storage Tips for Old Fashioned Chocolate Buttermilk Cake

Serve your Old Fashioned Chocolate Buttermilk Cake with a scoop of vanilla ice cream or a dollop of whipped cream. Alternatively, pair it with fresh berries to contrast the richness. If desired, dust the top lightly with powdered sugar for a decorative touch.

To store, keep it in an airtight container at room temperature for up to 3 days. If you live in a hotter climate, refrigerate—but bring it to room temperature before serving so the cake isn’t too firm. You may also freeze slices wrapped tightly in foil and plastic wrap for up to a month; thaw overnight in the fridge.

Baking Variations and Troubleshooting for Old Fashioned Chocolate Buttermilk Cake

  • Make a gluten-free version by substituting a 1:1 gluten-free baking flour mix. The texture may change slightly.
  • Add a layer of jam before frosting to add fruity contrast.
  • Use sour cream instead of buttermilk if you don’t have buttermilk on hand; it offers similar acidity and richness.
  • If the cake top gets too brown, cover it loosely with foil for the final 10 minutes of baking.

In case your cake sinks slightly in the center, it might be due to opening the oven door too early or under-baking. Next time, wait until the last few minutes before checking, and test with a clean tester.

Why You’ll Love This Recipe for Old Fashioned Chocolate Buttermilk Cake
