Notes

  • This cake is amazing! It is sweet, rich, gooey, and just decadent. We love chocolate, so this one is always a hit!
  • I like to add the marshmallows after the cake is made. They get perfectly soft. I have made desserts before with marshmallows baked, and the marshmallows get a little tough.
  • I like to make this before guests arrive, so it is warm and gooey.
