Instructions

Bake for 30โ€“35 minutes, or until a toothpick inserted into the center comes out clean (the cake will be slightly fudgy).

As soon as the cake comes out of the oven, sprinkle the mini marshmallows evenly over the top.
Return the cake to the oven and bake for an additional 5 minutes or until the marshmallows are puffed and golden.

In a saucepan, combine the heavy cream, powdered sugar, cocoa powder, and melted butter.
Bring to a simmer over medium heat, stirring constantly, until smooth and slightly thickened.
Remove from heat and stir in the vanilla extract.

Top with the chopped walnuts, pressing them gently into the frosting.
