Ingredients
- All purpose flour: gives the cake its structure Always scoop and level for accurate measuring
- Unsweetened natural cocoa powder: brings true chocolate flavor For best results choose a high quality brand
- Granulated sugar: ensures just the right amount of sweetness
- Baking soda and baking powder: are key for a lofty rise Always check their freshness
- Salt: balances and sharpens the flavor profile
- Espresso powder: is optional but deepens the chocolate taste even further A good grocery store brand does the trick
- Vegetable oil: keeps the cake extremely moist Any neutral oil works but avoid olive oil for flavor
- Large eggs: add richness and help bind the batter Make sure they are at room temperature
- Pure vanilla extract: gives that bakery style aroma Go for real vanilla for the best results
- Buttermilk: provides moisture and a hint of tang Use full fat if possible
- Hot freshly brewed coffee: amplifies the cocoa notes without making it taste like coffee Use decaf if you want less caffeine
- Unsalted butter: is the base for a creamy buttercream Softened butter beats up smooth and luscious
- Confectioners sugar: melts beautifully into the frosting Sift if yours is clumpy

Step by Step Instructions
- Prep the Pans:
- Grease two nine inch cake pans and line the bottoms with rounds of parchment paper then grease the parchment This ensures the cakes release fully and avoids sticking
- Mix Dry Ingredients:
- Whisk together flour cocoa powder sugar baking soda baking powder salt and espresso powder in a large bowl Ensuring the cocoa powder is fully combined helps avoid lumps later
- Mix Wet Ingredients:
- Using a mixer or whisk combine the oil eggs and vanilla until smooth and creamy Add in the buttermilk and mix again until just blended
- Combine and Add Liquid:
- Gently pour the wet mixture into the dry ingredients Using low speed or a whisk blend together while pouring in the hot coffee The batter will be thin but this is exactly what makes the cake so moist
- Bake:
- Divide the batter evenly between prepared pans Bake in a preheated oven for about twenty three to twenty six minutes A toothpick inserted in the center should come out clean Slight sinking as cakes cool is normal for a chocolate cake with this much moisture
- Cool the Cakes:
- Set the pans on a wire rack and let the cakes cool completely in their pans before frosting Handling them too early can lead to breakage
- Make the Buttercream:
- Using a mixer whip the butter until creamy Add the confectioners sugar cocoa powder heavy cream salt and vanilla Beat first on low then at high speed for a minute Check the consistency and add more sugar or cream if needed The frosting should be spreadable and hold soft peaks
- Assemble and Frost:
- Level the cooled cakes with a serrated knife if domed Place the first layer on a serving platter Spread frosting generously over top Add the second layer and cover the cake entirely with the remaining frosting Use a bench scraper or spatula to smooth over the sides Scatter chocolate chips on top for decoration
- Chill and Serve:
- Let the cake chill in the refrigerator for thirty to sixty minutes before slicing so the layers set Serve the cake slightly chilled or at room temperature according to your preference

My favorite ingredient in this cake is the espresso powder It truly elevates the chocolate flavor to another level I still remember the first time I tried it in my grandma’s old kitchen and we were all amazed at how deep and flavorful the cake turned out
Storage Tips
Store leftover chocolate cake tightly wrapped in the refrigerator for up to five days This cake also freezes beautifully Either freeze the frosted cake as a whole or slice and wrap individual pieces in plastic wrap then place in a zip bag Defrost overnight in the fridge and bring to room temperature before serving for the best flavor
Ingredient Substitutions
No buttermilk No problem Make a quick substitute by adding a splash of vinegar or lemon juice to regular milk and letting it sit for a few minutes Do not skip the coffee if possible but in a pinch hot water works too Choose coconut oil or canola oil as alternatives to vegetable oil If you are out of confectioners sugar blend granulated sugar in a high speed blender
Serving Suggestions
This cake stands alone but pairs wonderfully with a cold glass of milk Try serving with a scoop of vanilla or coffee ice cream for celebrations For a more festive look decorate the top with sprinkles chocolate curls or fresh berries
Cultural Notes
Chocolate cake has been a classic in American baking since the early twentieth century There are countless versions but this one sticks out thanks to extra moisture from oil and buttermilk plus the addition of coffee Which makes it rich and memorable just like bakery cakes from childhood birthday parties
Recipe Questions
