Pin it This classic American chocolate cake delivers rich, moist layers with a decadent cocoa buttercream frosting. The batter comes together quickly with basic pantry staples, while the boiling water creates an incredibly tender crumb. Bake two 8-inch rounds, cool completely, then sandwich and frost with the smooth chocolate frosting for a stunning celebration centerpiece that serves 10-12 people.
My apartment smelled like chocolate paradise when I first attempted Matildas recipe on a rainy Sunday afternoon. I had no idea something so decadent could come from such humble pantry staples. The boiling water trick genuinely terrified me, but that thin glossy batter bakes into the most incredibly moist cake Ive ever made.
Last summer I made this for my sisters birthday and watched her literally scrape the frosting off the serving plate. My nephew asked if I could bake it every single weekend. Something about old fashioned chocolate cake just makes people feel at home.
Ingredients
- 200 g all-purpose flour: The foundation that gives structure while keeping everything tender and light
- 200 g granulated sugar: Sweetens perfectly while contributing to that gorgeous moist texture we all love

Pin it My grandmother would have adored how this cake makes the whole house smell like a bakery. Sometimes the simplest recipes are the ones that become family legends.
Making It Ahead
I bake the layers a day ahead and wrap them tightly in plastic wrap at room temperature. The frosting can be made ahead too and stored in the refrigerator then brought to room temperature before spreading.
Storage Secrets
This cake actually tastes better on day two when all the flavors have had time to meld together. Keep it covered at room temperature for up to three days though it rarely lasts that long in my house.
Serving Suggestions
A warm slice with vanilla ice cream is absolute heaven. I also love serving it with fresh raspberries or strawberries to cut through all that rich chocolate.
- Sprinkle a pinch of flaky sea salt on top of the frosting for a sophisticated touch
- A dollop of whipped cream on the side lightens up each serving beautifully
- Pair with a bold red wine or strong coffee for the ultimate dessert experience

Common Recipe Questions
- → What makes this chocolate cake so moist?
-
The boiling water added to the batter creates steam during baking, resulting in an exceptionally moist and tender crumb while activating the cocoa powder for deeper chocolate flavor.
- → Can I make this cake in advance?
-
Yes, bake the layers up to 2 days ahead, wrap tightly in plastic, and store at room temperature. Frost the day of serving for best texture and appearance.
- → How do I store leftover cake?
-
Keep covered at room temperature for up to 3 days, or refrigerate for up to a week. Bring to room temperature before serving for the best texture and flavor.
- → Can I make this dairy-free?
-
Substitute the butter with vegan butter alternative, whole milk with almond or oat milk, and use plant-based oil instead for a completely dairy-free version.
- → Why is my batter so thin?
-
The boiling water creates a thin, glossy batter intentionally. This consistency is correct and essential for achieving the moist, tender texture of the finished cake.
