-For a dairy-free version, substitute almond or oat milk
-Replace all-purpose flour with 1:1 gluten-free flour blend if needed
-Dark cocoa powder can replace regular for a more intense flavor
-Coffee can substitute for half the hot water for deeper chocolate notes
Instructions
Step 1: Prepare Your Baking DishPreheat your oven to 350°F (175°C). Lightly grease an 8x8-inch baking dish or a 2-quart casserole dish. The size matters here—too large a dish will result in a thin cake with minimal pudding, while too small might cause overflow during baking.Step 2: Mix the Dry Cake IngredientsIn a medium bowl, whisk together the flour, granulated sugar, 2 tablespoons cocoa powder, baking powder, and salt. Whisking these ingredients thoroughly promotes even distribution of the leavening agents, ensuring your cake rises uniformly.Step 3: Add Wet Ingredients to Form Cake BatterStir in milk, oil, and vanilla to the dry mixture until just combined. The batter will be relatively thick—this is exactly what you want for the perfect cake-to-pudding ratio. Avoid overmixing, which can develop gluten and make your cake tough rather than tender.Step 4: Transfer Batter to Baking DishSpread the cake batter evenly in your prepared baking dish. Use a spatula to ensure it's level, as this will help create an even pudding layer beneath.Step 5: Create the Pudding LayerIn a separate bowl, combine brown sugar and ¼ cup cocoa powder. Sprinkle this mixture evenly over the cake batter—don't stir it in! This creates the foundation for your pudding layer.Step 6: Add Hot WaterCarefully pour the hot water over the entire surface. Again, resist the urge to stir—what seems like a mistake is actually the magic of this recipe! The hot water activates the cocoa and sugar, which will sink during baking to create your pudding layer.Step 7: Bake to PerfectionBake for 35-40 minutes until the top is set but the center still jiggles slightly. The cake is done when a toothpick inserted into the cake portion (not all the way to the bottom) comes out with moist crumbs but not wet batter.
