Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish and set it aside.
In a medium saucepan, melt 1 cup of butter over medium heat. Stir in 1/2 cup of cocoa powder until smooth. Remove from heat and let it cool slightly.
In a large mixing bowl, beat the eggs and sugar together until light and fluffy. Gradually add the cooled cocoa mixture, mixing until well combined.
Sift the flour and salt into the wet ingredients and stir until just combined. Add the vanilla extract and fold in the chopped pecans, if using.
Pour the batter into the prepared baking dish and spread it evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Add the Marshmallows:
Immediately after removing the cake from the oven, sprinkle the mini marshmallows evenly over the top. Return the cake to the oven for 3-5 minutes, or until the marshmallows are soft and puffed up.
Make the Frosting:
In a medium saucepan, melt 1/2 cup of butter over medium heat. Stir in 1/4 cup of cocoa powder and milk, bringing the mixture to a gentle boil.
Remove from heat and gradually whisk in the powdered sugar until smooth. Stir in the vanilla extract.
Frost the Cake:
Pour the warm frosting over the marshmallow-topped cake, spreading it evenly to cover the marshmallows. Allow the cake to cool completely on a wire rack before cutting into squares.
