This Small Batch Chocolate Cake is everything you love about a classic chocolate cake — rich cocoa flavor, tender crumb, and silky frosting — in a perfectly portioned size for just 2 to 4 servings. Whether you’re baking for date night, a birthday treat, or simply a chocolate craving, this cake delivers big flavor without the leftovers.
Baked in a 6-inch pan or as two mini layers, it’s easy to whip up with simple pantry ingredients and no mixer required. The result is a moist, fudgy cake topped with smooth chocolate ganache or buttercream — indulgent, intimate, and effortlessly satisfying.
Ingredients Overview
This cake uses classic ingredients scaled down for a small batch without sacrificing taste or texture.
Dry Ingredients
-
All-purpose flour: Just enough to hold everything together without drying it out.
-
Unsweetened cocoa powder: Choose Dutch-processed for deeper color and flavor, or natural cocoa for a classic bite.
-
Baking soda: Gives the cake lift and tenderness.
-
Salt: Enhances the chocolate and balances sweetness.
Wet Ingredients
-
Granulated sugar: Just enough to sweeten a single-layer cake without being cloying.
-
Vegetable oil: Keeps the crumb moist and soft — better than butter in small-batch cakes.
-
Milk: Use dairy or non-dairy milk (like almond or oat) — it adds moisture and richness.
-
Vinegar: Reacts with baking soda for a fluffy crumb. White or apple cider vinegar both work.
-
Vanilla extract: Deepens the chocolate flavor.
Optional Add-Ins
-
Espresso powder: Just ¼ tsp intensifies chocolate flavor without tasting like coffee.
-
Chocolate chips: For gooey chocolate pockets.
Frosting
You can choose between two options:
-
Chocolate Ganache – Rich and silky, made from chocolate and cream.
-
Chocolate Buttercream – Classic and fluffy, ideal for spreading or piping.
