- Top with marshmallows: Once the cake is baked, remove it from the oven and immediately sprinkle the mini marshmallows evenly over the top. The residual heat from the cake will soften the marshmallows, creating a gooey, marshmallowy layer that’s irresistible.
- Make the chocolate icing: In a saucepan, melt the butter over medium heat. Once melted, add the milk and cocoa powder, stirring until the mixture comes to a gentle boil. Once it reaches a boil, remove it from the heat.
- Whisk in the powdered sugar and vanilla extract until the icing is smooth and creamy. The icing should be thick but pourable.
- Drizzle the icing: Pour the warm chocolate icing over the marshmallows, making sure to cover the entire cake. The icing will melt into the marshmallows, creating a deliciously gooey topping.
- Cool and serve: Allow the cake to cool slightly before serving, or let it cool completely for a firmer texture. For a gooey, melt-in-your-mouth texture, serve the cake slightly warm. It’s delicious either way!
