  1. You can use any brownie mix that you like, we use fudge for this recipe. Or you can make your own homemade brownie mix.
  2. If you want a less gooey center then bake longer, if you want a more gooey center then bake for the time stated, the brownies will be done.
  3. We use mini marshmallows for the topping, but you can try large marshmallows but we have not tested this.
  4. Add some chopped chocolate to your brownie mix for some extra chocolatey flavor.
  5. You can substitute the coffee in this recipe for water, the coffee enhances chocolate flavor in baking recipes
  6. These can be eaten warm or cold, let them cool slightly before cutting.
  7. Keep an eye on the marshmallows when broiling, they can burn quickly.
