Dry Ingredients
- 2 cups flour
- 2 cups granulated sugar
- 3/4 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
Wet Ingredients
- 3 large eggs
- 1 cup milk
- 1 cup hot water or hot coffee
- 1/2 cup vegetable oil
- 2 teaspoons vanilla extract
Topping Ingredients
- 3 cups mini marshmallows
- 1/2 cup butter
- 1/4 cup cocoa powder
- 1/3 cup milk
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 23×33 cm (9×13 inch) baking pan thoroughly to prevent sticking.
- Mix Dry Ingredients: In a large mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt until evenly combined to create the dry base for your cake batter.
- Add Wet Ingredients: Incorporate the eggs, milk, vegetable oil, and vanilla extract into the dry ingredients. Mix until the batter is smooth and consistent with no lumps remaining.
- Add Hot Liquid: Slowly pour in the hot water or hot coffee while mixing at low speed. This will thin the batter and help dissolve the cocoa powder for a deeper chocolate flavor.
- Bake the Cake: Pour the thin batter into the prepared pan and place it in the preheated oven. Bake for 30 to 35 minutes or until a toothpick inserted into the center comes out clean.
- Add Marshmallows: Immediately after removing the cake from the oven, evenly sprinkle the mini marshmallows over the hot cake. Let them soften undisturbed for about 5 minutes.
- Make Chocolate Mud Sauce: While marshmallows soften, melt the butter in a saucepan over medium heat. Stir in the cocoa powder and milk, cooking for 1 minute until combined and smooth.
- Finish the Sauce: Remove the saucepan from heat and whisk in the powdered sugar and vanilla extract until the chocolate mud sauce is smooth and glossy.
- Drizzle Sauce Over Cake: Pour the warm chocolate sauce evenly over the softened marshmallows, allowing it to soak into the cake layers below for a rich, decadent finish.
- Rest and Serve: Let the cake rest for 20 to 30 minutes to allow flavors to meld and sauce to set before slicing and serving.
Notes
- Using hot coffee instead of water intensifies the chocolate flavor without adding caffeine if desired.
- Allow the cake to cool slightly before adding marshmallows to ensure they don’t completely melt.
- You can substitute vegetable oil with melted coconut oil for a slight flavor twist.
- Store leftovers covered at room temperature for up to 2 days or refrigerate for longer freshness.
- For a gluten-free version, substitute the all-purpose flour with a gluten-free baking mix of equal measure.
