INGREDIENTS:

For the Cake

1 cup (230 g) unsalted butter, melted

1/2 cup (50 g) unsweetened cocoa powder

2 cups (400 g) granulated sugar

4 large eggs

1 tsp vanilla extract

1 1/2 cups (190 g) all-purpose flour

1/4 tsp salt

1 cup (240 ml) buttermilk

For the Toppings

3 cups (150 g) mini marshmallows

For the Chocolate Frosting

1/2 cup (115 g) unsalted butter, softened

1/3 cup (30 g) unsweetened cocoa powder

4 cups (480 g) powdered sugar

1/2 cup (120 ml) milk

1 tsp vanilla extract

1/2 cup (60 g) chopped pecans or walnuts (optional)

DIRECTIONS:

Step 1: Prepare the Cake Batter

Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.

In a large mixing bowl, whisk together the melted butter and cocoa powder until smooth.

Add the granulated sugar, eggs, and vanilla extract, mixing until fully combined.

Gradually add the flour, salt, and buttermilk, stirring until just combined.

Step 2: Bake the Cake

Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Step 3: Add the Marshmallows

Remove the cake from the oven and immediately sprinkle the mini marshmallows evenly over the top. Return the cake to the oven for 2-3 minutes, or until the marshmallows soften and puff up. Let cool slightly.

Step 4: Make the Chocolate Frosting

In a medium saucepan over low heat, melt the butter. Stir in the cocoa powder until smooth.

Gradually whisk in the powdered sugar, milk, and vanilla extract, mixing until smooth and creamy.

Step 5: Frost the Cake

Pour the warm frosting over the marshmallow-topped cake, spreading it evenly with a spatula. Sprinkle with chopped pecans or walnuts, if desired.

Step 6: Cool and Serve

Allow the cake to cool completely before slicing into squares. Serve and enjoy!
