How to Make Simple Moist Chocolate Walnut Cake Recipe
Step 1: Prepare Your Oven and Pan
Start by heating your oven to a steady 350°F (175°C). Grease and flour an 8-inch round cake pan so your cake doesn’t stick and bakes evenly. This simple prep step sets the foundation for a cake that will come out perfectly every time.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until combined. This ensures that all the leavening agents are evenly distributed, which is key for a uniform rise and tender crumb in your Simple Moist Chocolate Walnut Cake Recipe.
Step 3: Add Wet Ingredients to Dry
Next, add vegetable oil, eggs, and vanilla extract to the dry mix. Stir just until everything is blended – avoid overmixing to keep your cake light and soft.
Step 4: Incorporate Buttermilk Gradually
Pour in the buttermilk slowly, mixing until the batter is smooth and creamy. The acidity from the buttermilk reacts with the baking soda for extra tenderness and a delightful slight tang.
Step 5: Stir in Hot Water
Add the hot water carefully, mixing until the batter thins out into a nice consistency. This step is crucial as it unlocks the cocoa’s richness, leaving you with a gorgeously chocolatey cake base.
Step 6: Fold in Walnuts
If you love a bit of crunch, gently fold in the chopped walnuts now, spreading them evenly throughout the batter to every slice gets a hit of nutty goodness.
Step 7: Pour Batter and Bake
Pour the batter into your prepared pan, smoothing the top slightly. Bake for 30 to 35 minutes until a toothpick inserted in the center comes out clean, signaling that your cake is baked to perfection.
Step 8: Cool and Serve
Allow your cake to cool in the pan for about 10 minutes, then gently transfer it to a wire rack to cool completely. This resting time lets the texture set beautifully, making it easier to slice.
How to Serve Simple Moist Chocolate Walnut Cake Recipe

Garnishes
A lovely way to elevate your chocolate walnut cake is by dusting it lightly with powdered sugar or topping it with a dollop of whipped cream. You can also sprinkle some extra chopped walnuts on top for an inviting finish that’s both pretty and tasty.
Side Dishes
Pair this cake with a scoop of vanilla ice cream or a drizzle of caramel sauce to bring in extra layers of flavor. Fresh berries or a simple cup of coffee or tea also complement the cake’s richness superbly.
Creative Ways to Present
For a festive touch, consider slicing the cake into petite squares and serving on a platter for a party. Alternatively, layer the cake with a cream cheese or chocolate frosting to create a stunning layered dessert that wows your guests.
Make Ahead and Storage
Storing Leftovers
Store any leftover cake tightly wrapped in plastic wrap or in an airtight container at room temperature for up to 3 days. This keeps the cake moist and fresh so you can enjoy it later without losing any of its charm.
Freezing
You can freeze this chocolate walnut cake by wrapping it securely in plastic and then in aluminum foil. Freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge to preserve texture and flavor.

Warm slices gently in the microwave for 10 to 15 seconds to refresh the moistness and enhance the chocolate aroma before serving, especially if you enjoy it with ice cream or a warm drink.
FAQs
Can I make this cake without walnuts?
Absolutely! The walnuts add a lovely crunch, but the cake itself is just as delicious without them. Simply omit the walnuts and enjoy a smooth, tender chocolate cake.
Is buttermilk necessary in this recipe?
Buttermilk helps tenderize the cake and adds a subtle tang. If you don’t have buttermilk on hand, you can make a substitute by adding a tablespoon of lemon juice or vinegar to a cup of milk and letting it sit for a few minutes.
Can I use a different type of oil?
Yes, vegetable oil is neutral and perfect here, but you can also use canola or light olive oil. Avoid strong-flavored oils to keep the chocolate taste prominent.
How do I know when the cake is done?
Use a toothpick inserted in the center; if it comes out clean or with just a few crumbs, the cake is ready. Overbaking can dry it out, so start checking at the 30-minute mark.
Can this cake be made gluten-free?
To make a gluten-free version, swap the all-purpose flour for a gluten-free flour blend that includes xanthan gum for structure, and ensure your cocoa powder and other ingredients are gluten-free certified.
