Basic Chocolate Cake (8 inch single layer)

If you’re on the hunt for a basic 8 inch chocolate cake recipe without multiple layers, just like my Moist Chocolate Walnut Cake, consider this your go-to recipe.

This is a one layer and one bowl chocolate cake recipe with a chocolate ganache frosting.

You can switch up the frosting with a basic chocolate buttercream frosting or an easy icing sugar + cocoa powder + water/milk icing.

The texture of this basic chocolate cake is fluffy and moist. By creaming together your butter and sugar, you will avoid a dry and dense cake and instead achieve the best results.

📋 Ingredient Notes & Substitutions

• Plain Flour: Use plain all-purpose flour. Check out my guide on how to accurately measure your flour and basic baking ingredients. 

• Cocoa powder: Use natural unsweetened cocoa powder or Dutch-process cocoa powder. 

• Baking powder: For best results use aluminum-free baking powder and make sure it’s not expired. You can test if your baking powder still works with this handy tip.

• Coffee: Use instant coffee powder and not coffee granules. 

• Salt: Use a fine sea/table salt or Kosher salt, not large/coarse granules.  

• Butter: Unsalted butter works best in this basic chocolate cake recipe. 

• Caster sugar: You can use either golden/raw or white caster sugar.

• Eggs: Must be at room temperature before adding them to your batter. Large eggs that weigh between 55g-65g (1.9oz-2.3oz). 

• Milk: Whole/full fat milk or almond milk can be used. Must be at room temperature. 

• Extra virgin olive oil: A quality extra virgin olive oil will produce the best results. Don’t use any other vegetable oil as they can add too much flavor that changes the result. 

• Vanilla extract: A nice vanilla bean extract tastes amazing but a regular extract works just as well. 

• Dark chocolate: Use a plain dark chocolate block of choice that you would be happy to consume. Cadbury baking chocolate or Lindt works great! 

• Canned coconut cream or regular thickened/heavy cream: I’ve tested this chocolate ganache using both canned coconut cream and dairy thickened/heavy cream and both work great! The coconut offers a mild coconut flavor which is nicely paired with the basic chocolate cake. 

🥣 Step By Step Instructions

There is a full and detailed recipe card at the bottom of this post.

1) In a medium size mixing bowl, add flour, cocoa, baking powder, coffee, and salt. Whisk until well combined. Set aside. 

2) In a large mixing bowl, using either electric hand beaters or a stand mixer with the paddle attached, add softened butter to the bowl.

3) Beat butter for a few seconds to break it up and it begins to turn creamy. This makes it easier on your beater when the sugar is added. 

4) Add sugar. Beat with the butter for 2 minutes until pale and creamy. Scraping down the sides as needed. 

5) Add eggs one at a time, beating for 10 seconds after each addition. Scrape down the sides as needed. 

6) Pour in milk, oil, and vanilla. Beat for 15 seconds until well combined. Scrape down the sides again.

7) Add half of the dry flour mixture and beat until just combined. Scrape down the sides and add the remaining flour. Beat until incorporated, ensuring not to over-mix.

8) Pour into the lined pan and smooth out the top with a spatula. Bake for 30-35 minutes, or until a skewer inserted into the middle comes out clean and it’s golden all over. 

9) Remove from oven and allow to cool in pan for 10 minutes. Carefully remove from pan and transfer to a wire rack to cool completely.

10) Pour cream into a small pot and gently warm over low heat. 

11) Break chocolate down into squares and place it into a small heat-proof bowl. Heat cream until warm and steam starts to come off the surface and small bubbles begin to appear around the edges, do not let it come to a boil. Remove from heat. 

12) Pour warm cream over the chocolate and let sit for 2 minutes. Gently stir the chocolate into warm cream until well combined and smooth. Set aside at room temperature for 30 minutes until it has thickened up to spreading consistency. 

13) Spread frosting over the cooled cake. Set aside and allow to set. Slice into triangles and enjoy. 

💭 Tips For Recipe Success

• Make sure to measure your baking ingredients accurately to achieve the best results. Check out my helpful guide on how to measure basic ingredients.

• I highly recommend you use a non stick baking pan. If your cake pan is prone to sticking, please grease it with butter and line it with parchment/baking paper. If you do have a non stick pan that works great, I always love to grease it with a layer of butter and dust cocoa over the butter, then tap out the excess. This will leave your cake with smooth sides.

• Ensure your refrigerated ingredients come to room temperature before making your chocolate cake. Using cold ingredients in cakes, they will not emulsify and blend appropriately with the rest of the ingredients, which results in problems with the final product. 

• Do not over-mix this cake batter as it will result in a tough cake texture after baking. 

• When heating up your cream for the chocolate ganache, ensure it doesn’t come to a boil as it will burn your chocolate. Wait for the ganache to thicken up to a spreadable consistency so it's easier to spread over the cake. Fasten up this process by transferring the ganache to the refrigerator. 

⏲️  Storing Instructions

• Store your chocolate cake in an airtight container, at room temperature, for 3-4 days. Transfer to the refrigerator after a few days if needed to keep it fresh from humid temperatures. 

• Freeze this basic chocolate cake by allowing it to completely cool after baking. Do not add the chocolate ganache frosting. Wrap it tightly in plastic wrap and then wrap it again in tinfoil. Freeze it for up to 3 months. 

• To defrost your cake, remove it from the freezer and place it in your refrigerator, it’s wrapped up, for a full 24 hours to slowly thaw.
